Abstract:-

Assessing ecosystem health and biodiversity requires an understanding of termite diversity and distribution. Using transect sampling across several seasons, this study examines the richness of termite species and their spatial-temporal distribution in Chikhli, which is in theBuldhana district of Maharashtra. Using standardized ecological indices (alpha, beta, and gamma diversity), the goal was to measure and examine termite diversity while evaluating the impact of seasonal variation on community composition. Using transects (100 m × 2 m), fieldwork was carried out in a few chosen semi-urban and forested environments in 2023 during the pre-monsoon, monsoon,and post-monsoon seasons. By manually inspecting termite mounds, decaying wood, soil, and leaf litter, termites were collected. Morphological keys and expert validation were used to preserve and identify each collected sample down to the species level. In all, 14 termite species belonging to the Rhinotermitidae and Termitidae families were recorded. Due to increased moisture and organic matter availability, alpha diversity peaked during the monsoon season, whereas beta diversity showed a moderate turnover of species across various habitats and seasons. An indicator of overall richness, gamma diversity demonstrated the research area’s ecological importance in maintaining termite biodiversity. Simpson’s diversity index and Shannon-Wiener’s diversity index provided more evidence for seasonal variations in species richness and evenness. Notably, Odontotermesobesus and Microtermesobesi showed ecological resilience by emerging as dominant species in every season. Statistical techniques, such as cluster analysis and Bray-Curtis dissimilarity, showed distinct patterns of seasonal gradient change in community structure. According to the study, temperature and moisture in particular have a significant impact on termite diversity in Chikhli, influencing both nest dispersal and foraging behavior. These results emphasize the necessity of localized biodiversity conservation measures and the significance of seasonal monitoring for comprehending termite ecology. In the semi-arid ecosystems of central India, this study provides important baseline data for future ecological assessments, sustainable land management techniques, and the potential creation of bio-indicators.

Aim:-To assess the termite species diversity and distribution in Chikhali, Buldhana District, Maharashtra, using transect sampling, and to evaluate seasonal variations through measures of alpha, beta, and gamma diversity.

Objectives:-

1. To document and identify termite species present in different habitats of Chikhali, Buldhana District, Maharashtra.
2. To analyze seasonal variations in termite diversity and distribution using transect sampling.
3. To evaluate alpha, beta, and gamma diversity indices to understand species richness and community turnover.

Introduction:-

Termites are one of the most ecologically important soil-dwelling insects in tropical and subtropical areas. They are necessary for the cycling of nutrients, the fermentation of organic materials, and the evolution of soil.They are bio-indicators of habitat quality and environmental stability due to their abundance and presence. In many regions of India, termite diversity is still poorly understood, especially at the regional level, despite their ecological significance. Chikhli is located in Maharashtra’s Buldhana district, which has a transitional climate that provides a variety of microhabitats that are conducive to termite species. Nevertheless, there is a dearth of information on species composition, seasonal dynamics, and diversity metrics in this area[1].

Combining alpha, beta, and gamma diversity metrics with transect sampling. This study seeks to close that gap by examining termite diversity and distribution over the seasons. For conservation planning, land use management, and sustainable farming practices in central India, an examination of the ways in which seasonal change affects termite assemblages can yield deeper ecological insights.

Ecological Significance of Termites in the Environment:

Termites are dominantly sentient in terms of habitat elucidation and soil motility, earning them the title of “ecosystem engineers.” They have a major impact on the breakdown of plant material that is high in cellulose, which speeds up the recycling of organic matter in ecosystems. Termites improve soil fertility and water retention by adding nutrients to the soil through the breakdown of decaying wood, leaf litter, and plant residues. Their tunneling action enhances microbial growth and soil aeration, both of which boost plant output[2].Moreover, termite mounds provide favorable conditions for a variety of plants and animals by influencing microclimates and landscape heterogeneity. Additionally, termites play a crucial role in the food chain as food for mammals, birds, reptiles, and other arthropods. They are sometimes considered pests because of the damage they cause to crops and wooden structures, but their ecological benefits greatly exceed their negative economic effects. It is essential to comprehend their function to preserve ecological stability and biodiversity, particularly in tropical and semi-arid regions.

Biodiversity Assessment and the Role of Diversity Indices

Termite diversity research offers important insights into habitat quality, climate change resilience, and ecosystem functioning. Three important metrics are frequently used to assess ecological diversity:

1. Alpha Diversity: Species richness within a particular habitat or sample site is represented by alpha diversity[3].
2. Beta Diversity: The turnover of species across various habitats or periods is measured by beta diversity.
3. Gamma Diversity: The overall diversity of a whole landscape or region is reflected in gamma diversity.

These metrics work together to help quantify environmental variability, species composition, and community organization. Accurate biodiversity evaluation requires an understanding of seasonal variations in these diversity indices.

Transect Sampling: A Systematic Approach:

A common ecological survey technique for studying biodiversity is transect sampling. Finding forage groups, mounds, and nesting locations in termite ecology entails examining designated belt transects[4].The technique guarantees quantitative, repeatable data collection across many habitat types and seasons, enabling researchers to identify trends in termite number and distribution.

Study Area:

The study was carried out in Chikhli, which is located in the Buldhana district of Maharashtra. The climate of this area is semi-arid to sub-humid, with distinct seasonal variations such as hot and dry pre-monsoon, wet and humid monsoon, and cooler and semi-dry post-monsoon phases. Numerous termite species find favorable niches created by the varied soil types, vegetation cover, and moisture regimes[5].Nevertheless, there is still little ecological documentation of the termite fauna in this area.

Research Gap and Significance:

Although research on termite biodiversity has been conducted throughout India, central Maharashtra lacks seasonal and localized studies. The majority of earlier research offers broad-scale or generalized data without taking ecological dynamics in space and time into consideration. This study closes that gap by employing a standardized analytical approach to provide a thorough, season-by-season investigation of termite communities[6].

Methods:-

1. Study Area Description:

The study was conducted in and around the Indian metropolis of Chikhli, which is situated in the Buldhana district of Maharashtra.With distinct pre-monsoon and post-monsoon seasons, this area has a semi-arid to sub-humid climate. Scrublands, semi-urban areas, agricultural fields, and degraded woods make up the landscape, which provides a variety of microhabitats that are appropriate for different termite species. This area is perfect for researching termite diversity and distribution patterns because of the seasonal variations in temperature, humidity, and soil moisture.

• Sampling Method: Transect-Based Survey:

The variety and distribution of termites were examined using belt transect sampling. In ecological field research, this method is commonly used and standardized, and it is especially helpful for identifying ground-dwelling and cryptic species like termites.

1. Transect Dimensions: The dimensions of eachtransect were 100 meters in length and 2 meters in width (100 m × 2 m), resulting in a total area of 200 m², 100 meters transect divide into 20 section, each section was (5×2 meter).
2. Sampling Sites: Two copies of each of the six transects were placed in three different habitat types: open scrublands, woodland patches, and agricultural land[7].
3. Sampling Seasons: To record temporal variance, surveys were carried out during three distinct seasons:
4. Pre-monsoon (April).
5. Monsoon (August).
6. Post-monsoon (November).

Every transect was carefully examined for termite activity, including termite-colonized decaying wood, nests, mounds, and indications of foraging.

• Termite Collection and Preservation:

Termites were manually gathered by inspecting:

1. Layers of soil
2. Dead logs
3. Bark from trees
4. Litter from leaves
5. Mounds in nature

Soft forceps were used to carefully collect termite samples, which were then preserved in 70% ethanol. Every colony or group that was encountered was regarded as a separate sample. Every piece of field data, including substrate, moisture level, microhabitat type, and GPS location, was captured on the spot[8].

• Species Identification:

Using common morphological keys and classification aids, specimens were identified down to the genus and species level. These included:

Chhotani and Roonwal (1989).

Krishna et al. (2013).

Diagnostic features such as mandibles, wing venation, soldier caste traits, and head capsule form were used to identify the species. Where required, expert verification was acquired.

• Diversity Indices and Data Analysis

Three essential ecological indices were used to examine termite biodiversity:

1. Alpha Diversity: Species richness and evenness within each habitat and season are calculated by using Shannon-Wiener and Simpson’s diversity indices.
2. Beta Diversity: Whittaker’s index and Bray-Curtis dissimilarity are used to analyze species turnover between habitats and seasons.
3. Gamma Diversity: The overall variation of the topography across the entire study area.

The data was handled and analyzed using PAST (Paleontological Statistics) software and Microsoft Excel.Seasonal and regional comparisons of diversity patterns were made using graphical representations and cluster analysis.

• Ethical and Environmental Considerations:

The natural environment was not significantly disturbed during any of the termite sampling operations. Non-target organisms and vacant structures remained undisturbed. The study complied with ecological and institutional standards for ethical biodiversity research[9].

Overview of Species Richness and Abundance:-

                     The study recorded atotal of 14 termite species across three major seasons: pre-monsoon, monsoon,and post-monsoon.

Fig 4:- Seasonal Trends in Termite Diversity and Richness

The pre-monsoon season has a Simpson Index of 0.800, indicating a good distribution of individuals among species, while the alpha diversity is 1.978, indicating substantial species diversity. Beta diversity is 0.273, and species richness is somewhat lower at 11, indicating a moderate turnover of species from prior seasons. The species composition varies moderately, as shown by the Bray-Curtis Index value of 0.251. O. obesus and M. obesi are the dominating species, and the gamma diversity is steady at 14 species[11].

More species diversity and even distribution are reflected in the monsoon season, when alpha diversity peaks at 2.051, the greatest of all seasons. Furthermore, the Simpson Index reaches its maximum value of 0.825, indicating a community with little balance and dominance.The monsoon season has the greatest number of species, with a species richness of 14. The lowest beta diversity is 0.135,suggesting that the species composition has not changed much. Higher resemblance with other seasons is indicated by the Bray-Curtis Index, which is likewise the lowest at 0.220.Gamma diversity continues at 14 species, while dominant species (O. obesus, M. obesi) do not change.

The Simpson Index is 0.805, and alpha diversity slightly declines to 1.981in the post-monsoon season, indicating both strong evenness and diversity[12].With a species richness of 12, the monsoon has somewhat decreased. Higher species compositional dissimilarity is suggested by the Bray-Curtis Index of 0.304and beta diversity of 0.182, both of which are higher than during the monsoon. Gamma diversity stays at 14 species, while the dominating species (O. obesus and M. obesi) continue to exist.

Conclusions:-

The current study used belt transect sampling in the semi-arid area of Chikhli, Buldhana district, Maharashtra, to provide a thorough investigation of termite variety and distribution over three seasonal phases: pre-monsoon, monsoon, and post-monsoon. Using ecological index-based evaluation and thorough field surveys, the results demonstrate how seasonal variations impact termite community composition, species richness, and spatial dynamics. A thorough evaluation of termite biodiversity’s intra- and inter-seasonal trends was made possible by the use of alpha, beta, and gamma diversity indices. According to the Shannon-Wiener and Simpson indices, alpha diversity peaked during the monsoon season, indicating favorable environmental factors such as more soil moisture and organic matter that promote a more varied and uniformly dispersed termite colony. Indicating that the monsoon season provides ideal habitat conditions for termite proliferation, species richness peaked at this time of year, with 14 species seen. Whittaker’s index and Bray-Curtis dissimilarity, which measure beta diversity, showed a moderate turnover of species throughout the seasons. This suggests that although core species such as Odontotermesobesus and Microtermesobesi are year-round, some species show seasonal variation in their occurrence and distribution. As a stable habitat for a variety of termite taxa, the region’s ecological value was highlighted by the fact that the gamma diversity, or overall termite diversity across all seasons, stayed consistent at 14 species.

Consistent observation of dominant species in every season showed their ecological adaptability and potential as bio-indicators of habitat and soil quality. Dissimilarity indices and cluster analysis were used to further show how climate factors like humidity and temperature affected the slow changes in community structure. The study concludes by highlighting the significance of regular biodiversity monitoring in addition to the seasonal patterns of termite diversity in a transitional setting. In the semi-arid regions of central India, these observations provide important baseline data for ecological conservation, sustainable land-use planning, and upcoming research on termite-driven ecosystem processes.

Abstract:-The intriguing features of MXene, a novel family of two-dimensional materials, include strong surface area, negative zeta potential, metallic conductivity, and electric conductivity.The majority of Mxene are currently only successfully prepared by exfoliating MAX with high concentration hydrofluoric acids. In this study, the 2D Ti₃C₂ with large interplanar spacing was successfully achieved by alkali mixture of NaF and HCl, in single process. The morphology and structure of prepared sample characterized by XRD and SEM. This work presents a safely effective route to synthesize the 2D Ti₃C₂. Fabrication of ZnO/MXene composites by a facile chemical method. Under UV irradiation, Rhodamine B was degraded by composites within 15 min and retained photo-catalytical efficiency after 5 cycles. Therefore ZnO/MXene composites can be regarded as aeffective candidate for waste water treatment and environmental protection.

1.Introduction:-Due to the discovery graphene in 2004[1-3], The 2D materials have attracted researcher interest. Owing to the reduction of the dimension and size, two-dimension materials have exhibited many intriguing properties that are not found in their bulk counters, holding tremendous promise for a host of applications ranging from electronics[4-6] and optoelectronic device[7, 8], photocatalysis[9, 10]to electrochemical catalysis[11, 12]. In recent years, with great advances in the synthetic techniques, more 2D materials beyond graphene have been successfully produced such as silicene[12], silica glass[13], molybdenum disulfide[14, 15], germanene[16, 17], stantene[18], phosphorene[19]. Among the, a newly discovered large family of 2D large family of transitional metal carbide/ nitride or carbonitride called ‘’MXene’[20], is rapidly rising starThese novel materials are produced from MAX phaseswith selective remove A layered using etchants without destroying M-X bond because the M-X bonds are much stronger than the M-A bonds[21]. MAX phasesare layered ternary compound with general formula of M_n+1AX_n(n=1,2,3), where M represents early transition d block transition elements, A is predominately IIIA or IV A group element, and X is either C or N,MAX phases possess hexagonal layered structure in which M_n+1X_n units and A layers are alternatively stacked.After the exfoliation resulting surface of MXene are terminated with other groups, such as -F, -OH and -O[22]. So, the MXene represents as M_n+1X_nT_x, Where T is the surface terminal groups depends upon etchants solution and condition. Experimentally, the proportions of different functional groups on the MXene surface are uncertain.In case of hydrothermal or electrochemical etching methods absence of terminal functional groups and represented as M_n+1X_n such as Ti₃C₂[23]. Most of MXeneshows metallic behavior exhibiting electronic conductivity higher than all other solution possessed 2D materials. These materials have shown significant promise in variety of applications including electrochemical energy storage[24], electromagnetic interference shielding[25], gas sensing[26], and many other. In particular, the good flexibility of MXene make easy to form composite with other materials, which provide an opportunity of integrating the outstanding properties of different materials in a complementary way. MXene also has exceptional capacity to transport photogenerated electron from closely coupled semiconductor photocatalyst and suppress the recombination of electron hole pairs[27]. However, MXene based photocatalyst system with more efficient for removal of water pollutants is still needed to develop.

ZnO is widely applied semiconductor photocatalyst in pollutants removal including heavy metal ions[28] and organic contaminants[29], and it has a strong oxidation capacity and a wide band gap (~3.3 ev)[30] because its valence band is sufficiently to generate hydroxy radicals[31]. On the other hand, ZnO shows fast recombination of electron hole pairs[32] and shows poorest photocatalytic degradation of dyes[33]. Based on above consideration, we constructed an efficient heterojunction photocatalyst for degradation of hazardous water pollutants which consisted of MXene sheets and ZnO. These heterojunctionsfacilitate minimize the photogenerated electron transfer distance. Moreover, the heterojunction structure between the stable ZnO and high conductive layered structure of Ti₃C₂T_x, MXene can further facilitate the separation and transfer capacities of photogenerated charge carriers. Therefore ZnO/Ti₃C₂T_x exhibited excellent photocatalyst. This work provides new insight into for development of traditional semiconductor photocatalyst for traditional semiconductor photocatalyst for highly efficient degradation of Rhodamine B as waste water pollutants.

3. Photocatalytical Application of ZnO/MXene composite

The Photocatalytical performance were evaluated through removal of Rhodamine B as typical pollutants 200 mg ZnO/MXene composites were dispersed into 40 ml of 50 ppm solution of Rhodamine B, uniformed stirring with help of magnetic stirring. The solution kept in dark for 30 min and then irradiated withUV light for 18 min the reaction sample were collected at regular of 3 min for UV-visible analysis. The same set of experiment carried using 100 mg of ZnO particle were used to evaluated photocatalytical performance and the rhodamine b solution were collected at regular interval of 20 min for UV-Visible analysis

     The degradation efficiency was evaluated by comparing percentage of degradation using following formula

η = (1-C_t/C₀) where η is photodegradation in % and C and C₀ are concentration of RhB solution after and before UV radiation, respectively. C/C₀ calculated by A/A₀, because the concentration of solution is directly proportion to absorbance of solution

Abstract

The main purpose of current study was to analyses biochemical composition (protein, lipid and moisture) appropriate amount of entire body wet weight tissue of 19 fish species which were previously recorded from four different stations i.e. Sakri, Kasare, Dahivel and Pimpalner during May, 2024 to April, 2025. The mined outcome was showed difference in diverse fish species with their biochemical composition. Protein was found in between (21.40 ± 01.25) to (11.05 ± 01.65), lipid ranges in (09.30 ± 01.80) to (01.10 ± 00.85) whereas moisture content ranges in (82.60 ± 01.15) to (70.50 ± 02.15). In all nineteen species of fishes had been recorded higher caloric value. Mystus bleekeri, Channa punctata and Mastacembellus armatus are more nutritionally beneficial fishes as compare to other 16 species.

Key words: Kasare, Caloric value, Mystus bleekeri, Dahivel.

Introduction:

Fish food is a highly proteinoids in nature. A large percentage of people consume it due to its low cholesterol, tender meat, and great taste. It is the cheapest source of animal protein and other vital nutrients that are important in the human diet, predominantly in low- and middle-income groups and it has been widely accepted as a good source of protein and other elements for maintaining a healthy body (Andrew, 2001).

The importance of fish as a source of high-quality, balanced and easily digestible protein, vitamins and polyunsaturated fatty acids and other organic products is well understood3. It is the most important source of animal protein. (Kumar et. al., 2020). The chemical composition of proteins and lipids has traditionally been used as an indicator of the nutritional value of fish as well as their physiological condition and habitat (Prakash and Verma, 2018)

The nature and quality of nutrients in maximum animals depend mostly on their food type. Besides, the feeding habit of an individual fish species significantly affects the nutritional composition of its flesh. Almost 85-90% fish protein is digestible and all the dietetic vital amino acids is found in the fish meet. The amount of roughly proximate composition together with protein and fats content is often essential to ensure the food monitoring necessities.

Material and Methods:

Present study was conducted at four selected stations from Sakri and Sakri Tahsil i.e. Sakri, Kasare, Dahivel and Pimpalner during June, 2023 to May, 2025. The geographical location of the study area has Sakri- (20⁰59’25” N and 74⁰18’52” E), Kasare- (20⁰56’57” N and 74⁰15’33” E), Dahivel- (20⁰59’25” N and 74⁰18’52” E), Pimpalner- (17⁰50’55” N and 74⁰52’30” E) (Google Earth,2015).

During the study, healthy, appropriately sized fresh fish specimens brought from fishermen. The entire sample was covered with inverted box for keeping freshness, brought them to laboratory. The fish were de-scaled wherever essential, their abdomens were cut open and they were washed two to three times with distilled water. Photographs were taken for identification and taxonomic studies. Fish were identified using various literature viz., Day (1994); Jayaram (2002); Talwar and Jhingran (1991). Proper amount of whole-body wet weight tissue of the fish was taken for biochemical analysis. The tissues were homogenized and centrifuged at 3000 rpm for 10 minutes for estimation of protein, lipid and moisture. Subjecting the body tissues to a solvent mixture of ethyl ether and ethanol (3:1) Bloor mixture. Six observations were made on each chemical analysis. The mean and standard deviation were calculated over the two-year study period. The estimated parameters content was determined by Protein by- Lowry O.H. (1951) method, lipid by – Jayaraman J. (1981) method Whereas total moisture by oven dried method – Anonymous, (1996) method.

Result and Discussion:

The existing study was carried out in total 19 previously recorded fish species from four different stations of Sakri Tahsil. Total 19 species were collected, which belonging to 6 orders followed by 10 families, 18 genera and species. Order Cypriniforms were dominated with 11 species and Family Cyprinidae with 10 species.

From Sakri (Tor khudree, Mystus bleekeri, Opsarius bendelisis, Devario aequipinnatus, Paracanthocobitis botia), from Kasare (Salmostoma bacaila, Labeo boggut, Mastacembelus armatus, Systomus sarana, Channa punctata, Puntius sophore, Oreochromis niloticus, Garra mullya), from Dahivel (Notopterus synurus, Mystus bleekeri, Cirrhinus reba) however from Pimpalner (Ompok bimaculatus, Hypophthalmichthys molitrix, Corica soborna) were identified. Analyzed nutritive values of Protein, Lipid and Moisture were estimated immediately on same day of collection. Six observations were taken of each parameter in two years study from June, 2023 to May, 2025. Mean and standard deviation were calculated and the values are shown in (Table no.-1) however graphical representation mentioned in fig. 1 to 4 with different stations.

Total Protein (%): As compare to others, protein is most leading biochemical parameter. Consumers gain from fishes near about 16% of animal protein. Protein is the second major component in muscle tissues of fish and is generally present in the range ranged in between 15 to 20 g/100g tissue. In some species lower or higher than this percentage of protein was found. Protein content of fish is considered low if it is below 15%. The extent of variations in protein level is comparatively low. Feeding habits, spawning cycle etc. affect the level of protein in the tissues. These results demonstrate that in good quality of protein is present in all fish species to fulfil the need of healthy diet. Higher content of protein evaluated in Mastacembelus armatus (21.40 ± 01.25)Least count of protein content estimated in Garra mullya (11.05 ± 01.65). Remaining 16 fish species shown protein range in between (11.10 ± 01.20) to (20.15 ± 01.05). Our findings are corroborated with Acharya et al. (2018).

Total Lipid (%): Lipids include a wide heterogeneous group of compounds. Lipids are defined as the fraction of any biological material extractable by solvents of low polarity. Variations in the lipid content are much wider than that in protein. Fish with fat content as low as 0.5% and as high as 16 18% are of common occurrence. In many species, there is a build-up of lipids during the feeding season and decrease during spawning (Bheem Rao and Sanjeevaiah, 2023). Percentage of Lipid shown variation in 19 fish species, stated in Lipids are most vital constituent of fish egg as reserve energy source, (Pal et al., 2011).  The maximum percentage of lipid shown in Corica soborna (08.85 ± 00.70), followed by Mastacembelus armatus (07.90 ± 00.85). Least count of protein content estimated in Mystus bleekeri (01.15 ± 00.85), Remaining 16 fish species protein ranges in between (01.35 ± 00.15) to (05.90 ± 01.40). Our study was corelated with some researchers, (Arunachalam et al., 2017)

Total Moisture (%): Water is essential for all living systems. Body fluids act as medium of transport of nutrients, metabolites etc. and water is the major component in these fluids. It is required for the normal functioning of many biological molecules.According to (Daniel, 2015) this type of relationship between moisture and fat is accurate for various body tissues as well as for whole body tissues. If moisture content increases, then fat content decreases, Praveen et al. (2018). Estimated percentage of the moisture ranges from (80.75± 01.60) to (45.45 ± 02.10) found in Hypophthalmichthys molitrix and Mastacembelus armatus respectively. Remaining 16 species are followed by (81.00 ± 02.80) to(60.00 ± 01.25).  

The biochemical composition of the fish muscle generally indicates the fish quality. Therefore, proximate biochemical composition of a species helps to assess its nutritional and edible values. Although several studies dealing with the proximate composition of biochemical components of many commercially important food fishes have been reported. Khalili and Sabine(2018) investigate lipids, protein, vitamins and minerals percentage in some fish species. Singh et al. (2016) stated that the amount of protein showed higher in liver due to greater concentration of enzymes. Kumar et al. (2020) analyses the effect of dietary vitamin-C on biochemical and morphometric parameters of Labeo rohita. Ali et al. (2020) estimated biochemical composition of some marine edible fish species from Kasimedu fish lading centre of Chennai. Patil and Patole (2025) estimated biochemical profile (Glycogen Protein, Lipid ad Moisture) of fresh water fishes from Nakana lake.

Conclusion

Generally, fish quality depends upon biochemical composition of the whole body which is revealing decline of energy reserves and storage of energy. Hence assessment of their edible and nutritional values related to energy element judge with other species. These values are noticeably varied within species. Based on the results of this research, it was observed that the diversity of fish fauna is more in Kasare village as compare to remaining three stations i.e. Sakri, Dahivel and Pimpalner. All nutritious fishes found in Kasare Village. It is recommended that further the reservoir can be consider being in good condition for fish production.

Abstract: For the preparation of omeprazole suspension granules are available in the market. In this research suspension is prepared by using combination of vehicle, preservative and pH regulator. After preparation of chemical stability is evaluated by using stability indicating parameters. Chemical stability of suspension is significantly increased after pH maintain in strongly basic side.  Storage temperature plays significant role in chemical stability. Storage container has no significant impact on chemical stability. Due to use of polysorbet 80, shelf life is increased to significant extent due to its properties such as preservative agent, wetting agent, suspending agent. Research highlights novel suspension medium preparation, its impact on chemical stability. Temperature and storage container impact on stability.

Keywords: Omeprazole suspension, Chemical stability, polysorbet 80, Temperature effect on stability, Noval suspension medium.

Introduction: Proton pump inhibitors commonly known as PPI. PPI is used in the treatment of GRED (Gastroesophageal reflux disease), gastric and duodenal ulcers, erosive esophagitis (1). Omeprazole is wildly used PPI. Omeprazole dosage forms available in market having is lyophilised injection, capsules and dry powder for suspension. Oral route of administration is most common for all medicinal product. However any liquid dosage is always considered as most efficient dosage form, due to having advantages as flexible dose proportionality, suitable for all patient such as elderly or children, high efficiency and quick action. But “Omeprazole” is highly unstable in liquid dosage form due to acid catalyzed and hydrolytic degradation in aqueous medium. Presence of water accelerates protonation resulted to loss in potency. To slow down the reaction speed high pH is maintained by using sodium bicarbonate (2). Refrigerated storage condition further increases stability due to reduction in kinetic energy. In spite of these stabilization process, chemical stability of omeprazole suspension is very less, typically less than 14 days, reflecting the fundamental chemical limitations of maintaining sulfoxide stability in aqueous systems (3).

Hence Noval suspension medium is prepared by using combination of water, polysorbet 80 and NaOH for pH regulation. Polysorbet 80 is surfactant which will be added to increase stability and  suspendability due to its wetting, preservation and other properties such as hydrophobic nature, chelating nature, viscosity enhancer etc. but not limited to. (4, 5, 6, 7).

Chemical stability is evaluated mainly as change in appearance, decrease in therapeutic efficacy and increase in impurity. The degradation is influence by light, temperature, reaction with container and closer, oxidation, moisture etc.

Materials and Methods: For the study omeprazole granules are procured from chemist which is manufactured by Dr. Reddy’s laboratories Ltd having brand name Omez Insta. The sachet is having label claim of 20 mg omeprazole. As per instruction provided on the sachet, complete sachet to be dissolved in water. Dubble distilled water is prepared in lab and used. Sodium hydroxide is procured from Merck and Polysorbet 80 (Vicapol 80) is procured from Viaswaat Chemicals.

For performance of test Morter Pestel, glass beaker, measuring cylinder is used to prepare suspension. For storage stability chamber of make Thermolab having storage temperature 2-8°C, 25°C & 60 % RH, 30°C & 75 % RH and 40°C & 75 % RH. For testing,pH meter, Oswal viscometer, Balance and Shimadzu HPLC is used (8).

For the determination of chemical stability of suspension, decided to perform test as Appearance, pH, Viscosity, Specific gravity, Assay, impurities and microbial limit test (8).

After preparation  suspension is stored in the glass bottle (Impermeable) and PET bottle (semipermeable) are used (9).

Figer 1 Molecular structure of Omeprazole.

Result Discussion:

Appearance:Evaluatedand foundcolour change indicates progressive degradation, which is more rapid at higher temperatures.

In the cold storage (2-8°C) it starts with off-white, and gradually changes to pale yellow, and eventually yellowish orange. Similar change in colour occurs in all storage temperature. But it will change quickly at elevated temperature such as 30°C & 40°C. 

pH: Evaluatedand foundpH decreases with higher temperature and longer storage, consistent with chemical breakdown.At refrigerated condition (2–8°C)pH remains 10.24 compared to initial 11.022, relatively stable.In room temperature (25°C) Slight decline over time to 10.04. At  30°C Noticeable drop 10.1in 45 days.40°C Clear downward trend from 11.02 to 10.31 in just 3 days.

Viscosity: Evaluatedand foundphysical consistency is largely stable, not significantly affected by storage. Across all conditions, viscosity remains in the range 2.4–2.7 mPa·s, showing minor fluctuations.

Density: Evaluatedand founddensity changes are modest, but higher temperatures show more variability. At refrigerated condition (2–8°C) it is ranging from 1.18 to 1.36 g/ml, in room temperature (25°C)slightly higher variation ranging from 1.11–1.42 g/ml. At higher temperature (30°C & 40°C) Variation is less which is 1.18 to 1.39 g/ml, But fluctuation are more.

Chart 1: Assay drift at various temperature over the period of storage.

Assay: Evaluatedand found Omeprazole suspension is stable at refrigerated conditions but loses potency faster at elevated temperatures.At refrigerated condition (2–8°C) Gradual decline but remains within 90–100% limit up to 60 days. In room temperature (25°C) assay drops faster and by 30 days it will be about 93 %. In the elevated temperature (30°C) assay falls below 90 % in 30 days. At accelerated temperature degradation reaction will be very fast due to kinetic energy. Very rapid decline observed and at 3 days assay is about 91 %

Impurities: Evaluatedand founddegradation products accumulate significantly at higher temperatures.Impurity D & E are generally below limit (NMT 0.15%), but at higher temperature 30–40°C levels it will approach/exceed thresholds (e.g., Impurity E up to 0.26%). Total impurities remain <0.5% at 2–8°C, but exceed limit at higher temperatures (30°C: 0.53%, 40°C: >0.5%). In the short period of time that is 30 days and 3 days.

Microbial Limit test: Microbial stability is maintained across all storage conditions. There is no impact of storage microbial susceptibility.

Chart 4: Storage container impact on assay                 Chart 5: Storage container impact on Impurity

Impact of storage containers are also evaluated and found that, there is no significant change in properties such as appearance, pH, viscosity and specific gravity due to storage container. Hear concluded that Glass bottles consistently show slightly better assay retention across all temperatures. However, there is significant impact on assay find below table for more clarity.

Temperature	Time Point	Glass Bottle	PET Bottle	Observation
2–8°C	90 Days	89.4%	86.7%	Both within spec; PET slightly lower
25°C	45 Days	87.6%	85.2%	Glass bottle shows better retention
30°C	30 Days	89.9%	88.5%	Solution in glass container is  more stable
40°C	3 Days	93.1%	91.7%	Glass maintains potency better

Table 1: Comparison of impact due to storage containeron assay.

When impurities are compared glass container is found less reactive. It might be due to inert and impermeable nature of glass.  However there is no significant difference in the impurity results. The limit of impurities are NMT 0.15 % for impurity D & Impurity E and NMT 0.5 % for Total impurity. Hence concluded that at elevated temperatures (≥25°C), PET bottles show higher impurity accumulation, especially total impurity. Glass bottles perform better in controlling degradation products.

Temperature	Time Point	Container	Impurity D	Impurity E	Total Impurity	Observation
2–8°C	90 Days	Glass	0.04	0.06	0.2	All within limits
		PET	0.06	0.12	0.41	Slightly higher but comparable to glass.
25°C	45 Days	Glass	0.14	0.16	0.46	Near limit
		PET	0.15	0.19	0.56	Exceeds impurity E and total impurity limit
30°C	30 Days	Glass	0.13	0.18	0.46	Exceeds limit of impurity E
		PET	0.19	0.16	0.53	All impurities within specification except total impurity.
40°C	3 Days	Glass	0.16	0.21	0.49	Exceeds limit except total impurity.
		PET	0.18	0.26	0.62	All impurities exceeds limit

Table 2:Comparison of impact due to storage containeron impurity.

Microbial Load: There is no significant increase in the load during the storage. Can be better understood by following table and graph. After evaluation it is concluded that PET bottles show slightly lower microbial counts across all temperatures.

Temperature	Time Point	Glass Bottle	PET Bottle	Observation

. Conclusion: Duering studyit is confirmed that the suspension stability is highest in refrigerated (2-8°C) condition, which maintains assay, low impurity and acceptable appearance up to 90 days. The stability found moderate at room temperature which is up to 30 days. At the elevated temperature potency drops below acceptable threshold, and impurities crosses limit threshold in short period and stability is very poor which is only 3 days at 40°C. But the microbial load are well within limit. In the suspension suspendability is maintained throughout the storage period in refrigerated condition (2-8°C) also. When compared containers it is concluded that for cold chain storage (2-8°C) both the containers are suitable. For ambient and elevated temperature glass bottles are preferred due to better impurity control. Though PET bottles offer better microbial resistance but may compromise impurity thresholds and assay retention under stress. The designed solvent for suspension is effective in increasing the physical and chemical stability of suspension.

1. Introduction

After the industrial revolution demand of energy completely rely on energy extracted from fossil fuel (oil, gas and coal) but it causes a severe effect on human health like cardiovascular disease, respiratory syndrome, cancer, reproductive effects, etc. and it can happen due to the evolution of carbon dioxide, carbon monoxide, CFC, and other toxic gases which may leads to greenhouse effect. To get ride from this problem we need to adopt renewable energy resources like hydroelectric energy, solar energy, wind energy, geothermal energy, tidal energy, and biomass energy.^[1] There is a challenge in effectively storing energy extracted from these resources. To address this issue electrochemical energy storage system (EES), namely supercapacitors and batteries have become crucial technologies.^[2] Energy density of batteries is higher than the supercapacitor but power density of batteries is lower than the supercapacitor so for rapid charging and discharging applications supercapacitor are more convenient. Continuous research progression in this area is due to wide range of applications such as industries, medical field, military, automobile sector, etc.

In recent days automobile sector mostly relies on lithium-ion batteries due to higher energy density and safe during handling.  Lithium is a key part of batteries that runs electric vehicles but due to limited availability of lithium it really hard to keep up with demand and supply. Researchers are continuously working on replacement of lithium to alkali metals like sodium cause abundant in nature and low cost but sodium ion batteries having poor cyclic performance.^[3] In comparison to batteries supercapacitor having some positive features like fast charging- discharging cycles. Supercapacitor require 1-10 s and batteries require 0.5-5 hr. charging -discharging time. Power density defines how quickly energy can be delivered or receive per unit mass (W/kg): supercapacitor having higher power density 500-10000 W/kg and batteries having power density less than 1000 W/kg. Supercapacitor have longer lifetime more than 500,000 hrs. and batteries 500-1000 hrs. Energy density defines amount of energy stored per unit mass: energy of batteries 10-100 Wh/kg more than supercapacitors 1-10 Wh/kg.^[4] The Ragone plot shown in graph 1. provide the information about behavior of electrochemical energy storage devices power density and energy density.^[5]

Conventional capacitor having lowest energy density and higher power density in comparison to other electrochemical energy storage devices. Supercapacitor having lower energy density and higher power density also batteries having higher energy density and lower power density compared to other electrochemical devices.^[6] To overcome the limitations of conventional batteries, supercapacitors have emerged as a promising electrochemical energy storage device. Unlike batteries, supercapacitors require electrode materials that exhibit high electrical conductivity, a large electrochemically active surface area, and well-tuned porosity to facilitate rapid ion transport. In addition, excellent thermal and chemical stability of the electrode material is essential to ensure long-term performance and safety. The development and fabrication of such advanced electrode materials play a crucial role in enhancing the energy density and overall efficiency of supercapacitor systems.

2. Synthesis Method

Cobalt sulfide (CoS) can be synthesized through several methods, depending on the desired properties and the form of the material. In this review article most of the materials are synthesize by hydrothermal method, solvothermal method, microwave induced synthesis, chemical bath deposition (CBD) etc.

2.1 Hydrothermal Method

This is a popular method for synthesizing CoS nanostructures, such as nanoparticles, nanowires, nanotubes etc. It involves a chemical reaction in an aqueous solution at elevated temperature and pressure. It involves crystalizing materials from aqueous solutions at high temperatures and pressures within a sealed and compact vessel. This method has some advantages facilitates the growth of nanostructured materials with controlled morphologies.

 It provides precise control over particle size and morphology, form crystalline structures at relatively low temperatures and allows to enhance material properties. This method also has limitations, requires specialized equipment to withstand high pressures. Extended reaction times may be necessary to achieve desired crystallinity.^[7]

2.2 Solvothermal Method

In this method chemical reaction carried out in an autoclave which sealed vessel using a different solvent at high temperature and controlled pressure. Due to this conditions nucleation and growth of materials of materials occurred in a controlled manner. This method having some advantages, it allows precise control over particle size, crystallinity, shape and growth of pure materials. It suitable for synthesis of wide range of nanostructure of metal sulfides, oxide and hydroxide.^[8]This method has some limitations like the process is time consuming and it run with help of high pressure; scalability is also a problem.

2.3 Microwave-Assisted Synthesis Method

Microwave-assisted synthesis involves rapid heating of reactants using microwave radiation, enabling uniform nucleation and growth of nanomaterials. Heating occurs due to the interaction of 2.54 GHz microwave energy with polar molecules and ions via dipole polarization and ionic conduction mechanisms. This technique offers reduced reaction time, uniform heating, and high energy efficiency. However, limitations include restricted precursor selection and challenges in large-scale production.^[9]The method has been effectively applied to synthesize metal sulfide nanoparticles, metal oxide nanoparticles etc. for high-performance supercapacitor electrodes.

2.4 Chemical Bath deposition (CBD) Method

The chemical bath deposition (CBD) technique is a low-cost and simple method used to deposit thin films of materials from a solution. In this method, the substrate is immersed in a chemical bath containing metal ions and a suitable complexing agent. Controlled chemical reactions in the solution lead to the slow and uniform deposition of the material onto the substrate surface. The deposition occurs due to the controlled release of ions and subsequent nucleation on the substrate. Parameters such as bath temperature, pH, concentration of reactants, and deposition time play an important role in determining the thickness, morphology, and quality of the deposited film. CBD has several advantages. It is simple, cost-effective, and does not require vacuum or high-temperature conditions. It allows large-area and uniform film deposition and is suitable for coating complex-shaped substrates.^[10] However, the technique has some limitations, such as poor adhesion, lower crystallinity, and limited control over film thickness compared to advanced deposition methods.

Abstract:

Biological control of plant pathogen by microorganism has been considered more natural and environmentally acceptable alternative to the existing chemical methods^[1]. Biological control has been developed as an alternative to synthetic fungicide treatment and considerable success had been achieved upon utilizing antagonistic microorganism to control both pre harvested and post harvested diseases^[2]. A variety of microbial antagonistic has ability to control several pathogens of various fruit and vegetables^[3].

            Antifungal assay using bacterial isolates such as P. fluorescens ATCC 9028 was tested against ten fungal pathogens of leafy vegetables. P. fluorescens ATCC 9028 was most effective with 58.19% fungitoxic activity against all tested fungal pathogens. Among the tested pathogen, F. moniliforme was highly susceptible with 65.78% inhibition and P. pullulans was highly resistant with 44.02% inhibition against all three antagonistic bacteria.

Keywords: Biological control, antagonistic bacteria., P. fluorescens etc.

Introduction:

On an average each crop plant can be affected by hundred or more than hundred diseases. The development of new physiological race pathogens to many of the systemic fungicides is gradually becoming ineffective. The biological control agents have enormous antimicrobial potential. They are effective in treatment of infectious diseases, simultaneously mitigating many of the side effects which are associated with pesticides. Therefore, there is growing realization in the people that biological control can be successfully exploited as an agricultural method for soil borne pathogens^[4].

            Beside this, Biological control of numerous crops by application of antagonistic bacterial isolates from suppressive soils has been accomplished during last two decades all over the world^[5]. The bacterium has been reported to be effective in controlling Phytopthora and Pythium amongseveral soil borne plant pathogens^[6]. Several studies have been demonstrated reduced incidence of disease in different crops after supplementing the soil with bacterial antagonists^[7]. Rhizosphere bacteria are excellent agents to control soil borne plant pathogens. Bacterial species like Bacillus, Pseudomanas, Serratia and Anthrobacter have been proved in controlling the fungal diseases^[14,15]. More recently an increasing number of reports have been focused on the potential of Bacillus subtilis as a biocontrol agent^[8]. A successful biocontrol agent efficiently suppresses the pathogen and reduces disease incidence. Biocontrol agent acts against pathogens by antagonism- competition, antibiosis and parasitism therefore in recent years a new biocontrol agent, Pseudomans flouresence have drawn attention due to the ability to produce secondary metabolites such as siderophore, antibiotic, volatile metabolites, HCN, enzyme and phytochrome which were highly antagonistc component to various phytopathogens^[9]. Pseudomonas flourescence is effective candidate for biological control of soil borne plant pathogens owing to their versatile nature, rhizophere competition and multiple mode of action^[10,11,12].

Material and method:

            Biological control of numerous crop diseases by application of antagonistic bacterial isolates from the soil has been accomplished during last two decades all over the world^[13,14,15]. Hence for the assessment of antifungal activity, the three bacterial isolates which has high antagonistic activity were procured from the Department of Microbiology, Government Institute of Science, Aurangabad as fallows,

            1)         Pseudomonas fluorescens ATCC 9028

            There after this bacterial cultures were transferred to fresh Nutrient agar slants in triplicates and were kept at 4⁰C in refrigerator for further studies.

Antifungal activity by antagonistic bacteria:

            The antifungal activity of three bacterial isolates was tested against ten pathogenic fungi of leafy vegetable by dual culture method^[16]. The antagonistic bacteria and targeted fungal pathogen were inoculated dually on PDA medium in sterile Petri dish 2-2.5 cm apart from each other. Whereas Petri plate without bacterial inoculation served as control and incubated at 37 ± 1 ^oC for 7 days. The inhibition of growing fungi by tested bacteria was quantified as distance of radial towards and away from bacteria in relation to control. The percent inhibition of mycelial growth of the fungi was calculated using formula,

                                             100 (R₁-R₂)

                               I  =

     R₁  

                                    Where              I           =          Inhibition of mycelial growth.

                                                            R₁        =          Mycelial growth in control

                                                            R₂        =          Mycelial growth in treated.

Result:

            The antagonistic effect of bacterial isolates was screened by dual culture method^[16]. The bacterial cultures, Pseudomonas fluorescens ATCC 9028 was tested against ten fungal pathogens of leafy vegetables. After a week of incubation, the growth of targeted fungal pathogens towards and away from the bacterial antagonistic isolate was recorded. The percent inhibition of mycelial growth over control was tabulated.

The bacterial antagonistic, P. fluorescens ATCC 9028 had significantly inhibited the radial growth of all tested fungal pathogen of leafy vegetables. Among tested pathogens, F.moniliforme and F. oxysporum were most sensitive and revealed 68.42% and 66.66% inhibition of mycelial over control (Table 1). On contrary, A. carthami and P. pullulans were most resistant and showed 50.90% and 49.18% inhibition respectively. While remaining pathogens namely C. lindemuthianum, F. roseum, A. brassicae, A. humicola, S. verruculosum and H. sativum showed 62.31%, 60%, 59.45%, 57.81%, 54.23% and 53.01% respectively inhibition (Table 1; fig. 1).

On average, F. moniliforme was found to be most sensitive with 65.78%  and P. pullulans as most resistant with 44.02% against all three bacterial antagonistic when compared to other tested fungal pathogens (Table 1).

Among the three tested antagonistic bacterial cultures, P. fluorescens ATCC 9028 was most effective and showed 58.19% fungitoxic activity (Fig 1).

Discussion :

Antifungal activity of three bacterial isolates namely Pseudomonas fluorescens ATCC 9028 was tested against ten fungal pathogens of leafy vegetables by dual culture method. Similar work previously carried out by many workers and reported that bacterial isolates like Bacillus sp., Pseudomonas sp., Serratia sp. and Anthrobacter sp. have been proved their efficacy against many fungal diseases^[17,18]. In the present study among three tested antagonistic bacterial isolates, P.  fluorescens ATCC 9028 was most effective one and revealed 58.19% inhibition of mycelial growth all ten targeted fungal pathogens. Similar finding were reported by Moataza and Saad^[19] and mentioned that five isolates P.  fluorescens were effective and showed 56% inhibition of Phythopthora capsici and 58.08% inhibition of Rhizoctonia solani.  

Among the tested pathogens, F. moniliforme was most susceptible with 65.78% inhibition on contrary P. pullulans was most resistant with 44.02% inhibition against all three bacterial isolates. Antagonistic activity may be due to the production of secondary metabolites such as siderophore, antibiotic, volatile compounds, HCN, enzymes or may be due to phytochromes which were inhibitors of various phytopathogens^[18].

Introduction:

India has a great diverse agricultural systems as well as it posses’ rich agricultural resources, different geographical, factors had resulted into agricultural typologies. Therefore, important agricultural facility is usefulprogramme to improved productivity and thereby achieving rural development. They may beachieved by technological intervention and by adopting strategic cropping pattern. This would reduce the water requirement of agricultural without comprising agricultural output.Maharashtra is leading state in area and production of cereals crops in the country. According to some expert and farmers there is a shift from cereals crops to other because of water requirement, low input and high profitability over these crops.  Drought is a major problem in Dhule district. They are natural hazards and are related with rainfall. Drought may be best benefited as persistent and abnormal moisture deficiency that has an adverse impact on agricultureAgriculture in this district is mostly of intensive subsistence type. There are two main crop growing seasons, its Kharif and Rabbi. Jawar crop is grown in both seasons.

Study area: The shape of the study area is triangular. It is located in the northern part of the Maharashtra State. It has occupied over an area of 8063.11 sq.km. It is extended from 20⁰38 N to 21⁰39 N latitudes and from 73⁰50 E to 75⁰13^l E longitudes (Fig. No.1). Dhule district contributes 2.62 percent total geographical area of the Maharashtra State. As per the 2011 Census, the population of Dhule district is 2,048, 781. The density of population is 285 persons per sq. km.

Objectives:

            To study the temporal changing cropping pattern of Dhule district.

            To study the relation between rainfall and cropping pattern of Dhule district.

Hypothesis:

Cereals cropping pattern depend on rainy days and annual rainfall

Database and Methodology:

            In this study secondary data have been collected from various socio-economic reports of Dhule districts. Analysis the 2005 and 2015 is cropping pattern. Simple statistical techniques are used to analyze the changing trend in cropping pattern, for calculating transformation the data 2005 and 2009 are compared. The data have been summarized processed and representedwith graph and map using GIS software, MS Excel was applied to process and analysis the data.In the present paper out of all crops only cereal cropping pattern has been studded. Cereal crops like Bajara, Rice, Wheat, Maize, Jower, Nachani and Pulses are studded.

Results and Discussion:

Dhule district comes under drought prone area. Cereal crop is a major crop in this district. Tahsilwice rainfall is varied; hence cereals crop cultivation is also uneven. Annual rain fall is highest in Shirpur tahsil (above 700mm). Shirpur tahsil does not come under drought area. Therefore amount of cereal crop is 43% of NSA in 2005 and 15% of NSA in 2015. Shindkhed Dhule and eastern part of Sakri tahsilcome under drought prone area. Hence near about 70% of NSA fall under cultivation area of cereal crops. In 2015 due to rainfall is increase cereal crop cultivation area has been declined from 60% of NSA (2005) to 37% of NSA (2015). Sakri tahsil stood first in cereal crop cultivation in Dhule district (70% of NSA 2005 and 51% of NSA in 2015)Bajara crop cultivated all over the district, area under Bajara crop in 2005 was 60.26% of NSA and in 2015 it was 37.16v. In 2015 due to increase in rainfall (Annual average rainfall 673mm) instead of cereal cropping pattern other cash crop cultivated area has been increased.

The net sown area in the Dhue district was 409900ha. and 390458ha. year 2005 and 2015 respectively.  This year cereals have occupied 247051ha. (60.26% of NSA) and 145096ha. (37.16% of NSA) area in 2005 and 2015 respectively. The main cereals crops have been Bajara, Jawar and Wheat are the important food grain crop in the district. Maize is mostly grown in the irrigated areas. High proportion of cereals indicated that the tahasils has very low level of commercialization of agriculture. The field observation revealed that the tahsils dominated by cereals with slightly more than half the cultivated areas.

Bajara :

Bajara is the important food crop cultivated in the district. It is generally taken in kharif season and hence it must have replaced hybrid that was grown in the same season. It is usually grown on the light to medium soil. It requires dry climate and less rainfall bajara is grown everywhere in the district. The use of high yielding verities of seeds is increased in the district. The farmer mostly areas this crop when the amount of rainfall is less. Through bajara is the important kharif crop it is also grown in rabbi season Dhule and Shindkheda tahasils. Rabbi bajara is grown in the summer season in the villages having the irrigation facilities.Climate of the district is suitable for Bajara crop. This crop can be taken low amount of rainfall. Sakri tahsil stood first in the cultivation area of bajara 33.51 % of NSA, it is follow by Dhule (30.59% of NSA), Shindkheda (24.46% of NSA) and lowest area under cultivation is Shirpur tahsil which is 15.22% of NSA in 2005. In 2015, due to increase in rainfall, inspite of bajara, maize and other cash crops have been cultivated.

Jowar:

Jawar is also important food grain crop in the district. It is cultivated in kharif and rabbi crop season. The jowar cultivation is basically related to firstly low rainfall and secondly soil in the district. It is traditionally cultivated as a rain feed crop in the both seasons.Jowar is cultivated all over the district. Highest area under cultivation of jower is in dhule tahsil (19.68% of NSA), which is followed by Shindkheda (15.12% of NSA), Shirpur (10.55% of NSA)and lowest area under jower cultivation is in Sakri tahsil(1.26% of NSA)in 2005. But in 2015, due to increase in average rainfall, area under this crop has been declined.

Rice:

Rice crop is cultivated only in western part of Sakri tahsil and Shirpur tahsil in Dhule district. The average annual rainfall in this area is 650 to 750mm, which is higher and suitable for rice crop. The area under cultivation is increased Sakri tahsil 3.72% of NSA in 2005 to 10.54% of NSA in 2015.  Dhule tahsil this crop is rarely cultivation and in Shindkheda tahsil rice crop is not cultivated.

Wheat:

Wheat is the third important food grain in the district. This crop is grown in the medium and black soil. It is cultivated in dry and cool month of rabbi season. The farmer has grown the crop on a very small scale in the district. The crop is taken as an irrigated crop. The agricultural land is prepared after the harvested season of bajara. Sowing is done in the month of Oct. / Nov. The crop date takes 110 to 140 days to mature from the date of sowing. Now, improved verities of seed are sown in the district. Wheat cultivation area increased the mainly because of increase in area under irrigation by Panzar, Kan and Kabryakhadak medium projects.This crop is cultivated very less (1 to 3.8% of NSA) Dhule district in 2015. Climate of the District is not suitable for this crop. Therefore, the average production of this crop is very less.

Maize:

Maize is important crop which is mostly usa as a fodder in the Sakri, Dhule and Shindakheda tahsils. The area under maize has increased for the year 2005 (4.23 of % NSA) to the year 2009 (5.63% of NSA). Maize crop gives a higher production and income of the farmer in Dhule district. The area under cultivation of this crop is increasing day by day. The climate of this District except Shirpur tahsil, is favorable for this crop. In 2005 higest area under cultivation of the crop is Sakri (9.82% of NSA) and it followed by Dhule (2.62% of NSA), Shindkheda (0.26% of NSA). The crop requires water in large amount. It needs irrigation facility.  In Sakri tahsil Panzara, Kan, Kamkheli and Kabryakhadak irrigation medium water tank. Whereas, in 2015, the area under cultivation of the crop is increased double higher due to hybrid seed and irrigation facilities.

Nachni:

Nachni is important kharif crop in only Sakri tahsil in Dhule district. The area under Nachani in year 2005 was 3.21 % of NSA and year 2015 was 0.75% of NSA in Sakri tahsil. The Nachani is grown on the light soil and heavy rainfall area.In high rainfall area, this crop is cultivation. In Dhule district, only in western part of Sakri tahsil Nachani crop is cultivated, which is due to the high rainfall in hilly area of Sayadri. The crop is cultivated in (3.21% of NSA) area as per 2005.

Pulses:

Pulses grown in all tahsils in Dhule district. It is dominant crop in shirpur tahsil. It is account 13.21% of NSA in year 2005 and 11.47% of NSA in year 2015. In the tahsil a variety of pulses area grown like Gram, Tur, Green gram, Mug, Chavali, Wal, Green peas etc. Almost all the pulses except Gram and Tur are cultivated in kharif season. Mostly varieties of pulses are cultivated in all tahsils in dhule district. The pulses are grown on light soil in the district.This crop can be cultivated in both less and high rainfall area. This crop is economically beneficial. The crop is cultivated in all tehsils of the district. In 2015 in Sakri tahsil, the crop is cultivated in 14.17% of NSA.

Generally, cereal crop is cultivated all over the district. If rainfall is increased, other crops like cotton, Sugarcane Vegetable can be cultivated in large amount. Dhule district is drought prone area, hence cereals cropping pattern analysis is essentional. Geographical and technological factors affect on the cereals cropping pattern.

Suggestions:

1. For cereals crop, instead of traditional cropping pattern, new technological cropping needs to be accepted for better results.

2. Newly developed hybrid seeds of cereals crop need to be used.

3. Where there is less rainfall, irrigation system based on new technology is to be used.

4. In less rainfall and less area, higher productivitycropping pattern to be accepted.

5. Fruit crop cultivated in less water area like Pomegranate, Crusted Apple, Ber etc. are to cultivated

6. Cereal crops should betaken for commercial purposes instead of traditional cropping pattern.

“Hydrogel-Based Growth of Cobalt Tartrate Single Crystals and Their Morphological Study”

Sachin J Nandre,

Dept of Physics, Uttamrao Patil College, Dahiwel (Dhule)

Abstract

Single crystals of cobalt tartrate (CoC₄H₄O₆·xH₂O) were successfully grown using the hydro-silica gel technique, which allows controlled nucleation and slow diffusion of reactants in a three-dimensional porous medium. Cobalt tartrate is a transition metal-organic complex with potential applications in catalysis, magnetic materials, and electrochemical sensors. The growth process was optimized by adjusting gel concentration, reactant molarity, and pH, resulting in well-faceted, transparent to pale pink crystals. The study demonstrates the effectiveness of the hydro-silica gel method for producing high-quality cobalt tartrate crystals and provides insights into their growth mechanism and morphology control.

Keywords: Hydrosilica gel, catalysis, electrochemical sensors.

1. Introduction

Cobalt tartrate, a coordination complex of cobalt and tartaric acid, exhibits unique optical, magnetic, and structural properties due to the d-orbital interactions of cobalt ions and the chelating behavior of tartarate ions. The controlled growth of single crystals of cobalt tartrate is essential for materials characterization and applications in electronics, optics, and catalysis.The hydro-silica gel technique is a soft chemical crystal growth method where reactants slowly diffuse through a gel matrix, enabling controlled nucleation and growth at ambient temperature. This method offers advantages over conventional solution growth, including, low temperature growth, avoiding thermal decomposition, control over crystal size and morphology, reduction of spontaneous precipitation.

This work aims to grow cobalt tartrate crystals using the hydro-silica gel method and study the effect of gel concentration, reactant molarity, and growth time on crystal morphology and size. Growth of crystal ranges from a small inexpensive technique to a complex sophisticated expensive process and crystallization time ranges from minutes, hours, days and to months. The starting points are the historical works of the inventors of several important crystal growth techniques and their original aim. The methods of growing crystals are very wide and mainly dictated by the characteristics of the material and its size.

2. Experimental Technique

2.1 Materials

The materials were purached from Lobachempvt ltd. All the materials were AR grade and they are used without any further purification. Cobalt chloride hexahydrate (CoCl₂·6H₂O), Tartaric acid (C₄H₆O₆), Sodium metasilicate (Na₂SiO₃·5H₂O) for gel preparation, Distilled water,Glacial acetic acid (for pH adjustment).

2.2 Preparation of Hydro-Silica Gel

Sodium metasilicate solution was prepared by dissolving 50 g of Na₂SiO₃·5H₂O in 100 mL of distilled water.The solution was acidified slowly with 1 M acetic acid under constant stirring until gelation occurred (pH ~4–5). The gel was allowed to set in test tubes and aged for 24–48 hours to strengthen the matrix. The following table 1 shows the standard optimized parameters for the crystal growth development.

Sr.No	Optimum Conditions	Cobalt Tartrate
1	Density of Sodium Meta Silicate	1.04gm/cm3
2	Conc. of Tartaric acid	0.5M
3	Volume of Tartaric acid	7ml
4	Volume of Sodium Meta Silicate	18ml
5	Volume of Cobalt Cholride	5ml
6	pH of the gel	4
7	Ageing Period	One week

The crystals were extracted by carefully breaking the gel after two to three weeks depend on the growth parameters.  The extracted crystals were subjected to study their physical properties particularly crystal size, growth morphology, crystal structure, and optical behavior. Growth morphology was studied by using scanning electron microscope. Crystal structure was identified by using X-ray diffraction technique.

3. Results and discussion

Crystal growth occurs via slow diffusion of Co²⁺ and tartrate ions through the hydro-silica gel.Gel acts as a porous medium, restricting rapid precipitation and promoting uniform nucleation.Chelation of cobalt ions by tartarate ions stabilizes the crystal lattice.Hydrogen bonding and van der Waals interactions within the gel network facilitate orderly crystal assembly. In the present experiment, a 0.1 M solution of cobalt chloride was carefully poured on top of the set silica gel and 0.1 M solution of tartaric acid was layered above the gel to allow slow diffusion. The test tubes were sealed to prevent evaporation and left undisturbed at room temperature (~25°C).Crystals started to appear after one week, and growth continued for up to three weeks in order to get full grown crystals with different facets.

It is observed that concentration of cobalt chloride and tartaric acid has significant effect on the growth of the crystals. It is found out that higher cobalt ion concentration increases the nucleation sites resulting smaller crystals and for lower concentration of cobalt ions slowed crystal growth, yielding larger but few crystals. However, the equimolar concentrations of cobalt chloride and tartaric acid resulted in optimal crystal quality.

Figure 2 shows the X-ray diffraction pattern of Cobalt Tartrate Single Crystals.  The orientations of (111), (200), (220), and (311) planes are observed which reveals well-defined crystal structure of the grown materials.

Figure 3 shows the microscopic SEM images of cobalt tartrate crystals. These crystals were pale pink to pink in color with transparent, and prismatic properties. The grown crystals shaped changed with respect to pH of the gel concentration. The shape of the crystals changed from spherical granule to crystal size ranged from 1–6 mm, depending on gel concentration and reactant molarity.Lower gel density led to faster diffusion, resulting in smaller but more numerous crystals.Higher gel density slowed ion diffusion, producing fewer but larger, well-faceted crystals.

4. Conclusions

Cobalt tartrate crystals were successfully grown using the hydro-silica gel technique. The study shows that gel density, reactant molarity, and pH are critical parameters in controlling crystal size and morphology. The hydro-silica gel method is effective in producing high-quality, well-faceted cobalt tartrate crystals at ambient temperature. These crystals can be used for further studies in materials characterization, optical properties, and catalytic applications.

Abstract

In the field of supramolecular chemistry, the detection of ions by using fluorescence and absorption techniques have gained significant importance due to their simplicity, high sensitivity and selectivity, low cost, detection limit, rapid response, and applicability to bioimaging. In recent years, Schiff-based receptors have been developed for the detection of various ions. This study mainly focuses on the fluorescent sensors which are based on Schiff base. 

Keywords: Chemosensor, Schiff base, Fluorescence, Molecular recognition. 

Introduction

In chemistry, environment, medicine and biology, cations play a vital role. In biological processes such as maintaining potentials across cell membranes, triggering muscle contraction, metal cations play an important role. On the other hand, some cations, such as lead and mercury, can cause harmful effects to the human body and the environment.In medical diagnostics, catalysis, environmental chemistry and physiology, several neutral and ionic species find extensive applications [1,2]. Excess accumulation of toxic ions may cause somesevere neurodegenerativediseases, such as Parkinson’s disease, Alzheimer’sdisease, amyotrophic lateral sclerosis (ALS), and Wilson’sdisease in the human body.

From above it is clear that detection of ions is necessary either they are useful or harmful. Fluorescent molecular sensors are used for detecting ions. Since fluorescent sensors are highly selective and easy to operate, they play an important role in many areas and disciplines.  The molecular recognition of cations and anions by using absorption and fluorescence technique are receiving great interest in the field of supramolecular chemistry [3-6]. Cation complexation chemistry has played a significant role in the origin of the field of molecular recognition, since in many areas,cations play an important role. For the detection of cations, anions and biomolecules wide range of highly selective and sensitive chemosensors have been developed [7, 8].

The present review highlights recent progress in Schiff base fluorescent probes used for sensing biologically and environmentally significant ions.

Sensors for Nickel

Liu et al. reported a highly selective colorimetric chemosensor (1) for detection of Ni²⁺ ions in aqueous system DMSO-H₂O (v/v = 1:1, pH= 7.4). The addition of 10 equivalent of Ni²⁺ to the aqueous solution of probe (1) results into a dramatic colour change from yellow to red. Absorbance spectra of probe (1) showed a new peak at about 525 nm. Titration plots in UV-visible spectra revealed 1:1 stoichiometry between (1) and Ni²⁺. Interference study shows that no significant changes in the UV-visible spectra was found with and without the other competing metal ions. The detection limit was found to be 2.2×10^-7M. [9].

Fegadeet al. reported a fluorescent receptor (2) for the determination of Ni²⁺ in semi-aqueous media DMSO-H₂O (1:1, v/v) solvent system. Upon addition of Ni²⁺ ion solution prepared in distilled water to the aqueous solution of receptor (2) gave remarkable fluorescent enhancement. Also, addition of 10 equivalent of Ni²⁺ to the aqueous solution of probe (2) causes color change from colorless to yellow. Interference study showed that interference of other tested metal ion in the detection of Ni²⁺ was insignificant. Job’s plot experiment indicates the formation of 1:1 complex between probe (2) and Ni²⁺[10].

Sensors for Zinc

Khairnar et al. reported a highly selective fluorescent ‘turn on’ chemosensor (3) for the detection of Zn²⁺ in DMSO-H₂O (90:10, v/v) solvent. The weak fluorescence of probe (3) was enhanced with red shift from 360 nm to 385nm (Δλ=25). The probe (3) was successfully applied for detection of Zn²⁺ in live HeLa cells. Interference study shows that probe (3) has high selectivity toward Zn²⁺even in the presence of same concentration of other metal ions. Job’s plot indicates 1:1 binding ratio between Zn²⁺ and probe (3). The detection limit was found to be 0.67 µM [11].

Tayade et al. reported a novel chemosensor (4) based on isonicotiamide for the detection of Zn²⁺. The probe (4) also shows selectivity towards HSO₄^–. Weakly fluorescent probe (4) showed highly selective enhancement in the emission wavelength at 470 nm for Zn²⁺. Interference study showed that no significant variation was observed in the fluorescence of probe (4) with Zn²⁺in the presence and absence of other cations.  LOD of probe (4) as a fluorescent sensor for the analysis of Zn²⁺ was found to be 3.81 nM. The fluorescence properties of probe (4) were effectively clarified by two chemical input (Zn²⁺ and HSO₄^–) OR INHIBIT type logic gates at molecular level [12].

Sensors for Copper

Yeh et al. reported a coumarin-based sensitive and selective fluorescent sensor (5) for the detection of Cu²⁺. In presence of Cu²⁺ probe (5) shows significant fluorescence quenching. Probe (5) upon addition of Cu²⁺ shows visible colour change from yellow to orange. Titration of Cu²⁺ with probe (5) shows that the absorbance at 487 nm decreased and new band at 440 nm was produced. Interference study shows that in presence of other competing metal ions no significant changes were observed in fluorescence spectra of probe (5) with Cu²⁺. Job’s plot revealed that 2:1 binding stoichiometry between Cu²⁺ and probe (5). The probe has limit of detection of 0.27µM. Moreover, probe (5) could be successfully used as a fluorescent probe for detection of Cu²⁺ in living cells [13].

Yang et al. reported a colorimetric and fluorescent sensor (6) for Cu²⁺ detection in methanol-water (3/7, v/v) solvent system. Upon addition of Cu²⁺ to the probe (6) results into enhancement of the absorbance with formation of new peak at 552 nm and the color of the solution changes from colorless to pink. When more than 1.0 equivalent of Cu²⁺ was added the enhancement was saturated indicating that the binding mode was probably of 1:1 stoichiometry. Same conclusion about binding mode was obtained from Job’s plot. The limit of detection for Cu²⁺ was found to be 0.096 µM. The competition experiments showed that no visible color change was observed and no change in the fluorescence spectra of probe (6) with Cu²⁺were observed in the presence of other competing metal ions. The probe (6) was successfully applied for the fluorescence imaging in living cells [14].

Sanmartin-Metalobos et al. Synthesized a fluorescent probe (7) for detection of Cu²⁺ in aqueous samples.  Spectroscopic studies show that probe (7) has higher affinity towards copper than other tested d-block metal ions. The detection limit of probe (7) for Cu²⁺ ion was found to be 8.7 nM [15].

Zhang et al. reported a novel chemosensor (8) for detection of Cu²⁺ ion in DMSO solution. Chemosensor (8) showed visible colour change from yellow to colorless on treatment with Cu²⁺ ion. The detection limit of chemosensor (8) forCu²⁺ ion was found to be 4.87 nM. The binding constant for chemosensor (8) and Cu²⁺ ion was determined as 6.15×10¹⁰ M^-1. Job’s plot revealed that 1:2 binding stoichiometry of the complex between chemosensor (8) and Cu²⁺ ion [16].

Sensors for Magnesium

            Kao et al. synthesized a turn on Schiff base fluorescent sensor (9) for the detection of Mg²⁺. The probe (9) alone shows no significant emission after excitation at 353 nm but upon addition of Mg²⁺, the fluorescence intensity of probe (9) increases significantly at the wavelength of 487 nm. Also, the probe (9) shows weak fluorescence enhancement upon addition of Ca²⁺ and Cd²⁺. On the other hand, probe (9) shows very weak fluorescent band towards other metal ions. The probe (9) was successfully applied to detect Mg²⁺ in different sources of water such as lake, ground and tap water. Job’s plot clearly shows 1:1 binding stoichiometry between probe (9) and Mg²⁺.The detection limit for probe (9) for the analysis of magnesium was found to be 19.1 ppb. The association constant for probe (9) and Mg²⁺ was determined as 1.91×10⁷M^-1 [17].

Wang et al. reported a turn on fluorescent sensor (10) based on Schiff base derivative for the detection of Mg²⁺. Fluorescence spectra show that upon addition of Mg²⁺ ion to the probe (10) displayed significant fluorescence enhancement with emission maximum at 547 nm due to the Photo-Induced Electron Transfer (PET) effect. No other metal ion except Mg²⁺shows change in the absorption and fluorescence spectra of probe (10). Interference study shows that even in presence of other competing metal ions probe (10) shows similar spectral changes that with Mg²⁺ion. Based on Benesi-Hildebrand the association constant for complex (10)-Mg²⁺ were determine as 3.33×10⁴ M^-1. The detection limit was found to be 5.16×10^-7M [18].

——————————————————————————————————————-Abstract

Kamala Das (1934–2009), a pioneering Indian English poet, is widely known for her confessional voice that merges the personal with the political. While criticism has largely emphasized her treatment of female desire, sexuality and identity, this paper argues that her poetry also forges a significant relationship between nature imagery, gendered experience and social protest. Through close readings of “An Introduction,” “The Old Playhouse”, “The Sunshine Cat” and “My Grandmother’s House”, the study examines how Das places the female subject within natural and domestic spaces shaped by patriarchal power. Nature in her poetry functions both as a metaphor for confinement and as a symbolic site of resistance, enables a critique of social expectations and gendered oppression. Using a feminist ecocritical framework and qualitative textual analysis, the paper explores images of birds, light, land, memory and domestic landscapes as expressions of women’s alienation and longing for autonomy. By foregrounding the ecological dimension of Das’s feminist poetics, the study demonstrates how nature intensifies her social protest and expands the scope of Indian English poetry as a medium of gendered resistance, ethical reflection and cultural critique. The paper contributes to existing scholarship by situating Kamala Das within a broader discourse of nature, gender and social justice.

Keywords: Nature, Gender, Kamala Das, Confessional voice, Indian English Poetry, Gender, Nature Imagery, Feminist Protest, Ecocriticism, Ethics, Cultural Critique

Introduction

Indian English poetry in the post-independence period reflects a sustained engagement with questions of identity, social change and cultural negotiation. Within this literary landscape, Kamala Das emerges as one of the most influential and controversial voices. Her poetry is marked by emotional candor, autobiographical intensity and an unapologetic interrogation of patriarchal norms governing women’s lives. While Das has often been discussed primarily as a confessional poet articulating female desire and sexual autonomy, such readings, though valuable, tend to overlook the complex symbolic structures through which her protest operates.

One such structure is nature imagery, which plays a crucial role in articulating emotional states, gendered experiences and social critique in her poetry. Nature in Kamala Das’s work is never a neutral or decorative presence. Instead, it is deeply implicated in the lived realities of women, functioning as a metaphorical extension of confinement, longing, resistance and memory. Through birds, sunlight, land, houses and landscapes, Das constructs a poetic vocabulary that critiques social institutions such as marriage, family and gender hierarchy.

This paper argues that Kamala Das uses nature imagery as a dialectical force -simultaneously reflecting women’s oppression and offering symbolic possibilities for resistance. Her engagement with nature enables her to articulate a form of social protest that is intimate rather than overtly political, grounded in everyday experiences rather than ideological slogans. By examining selected poems, this study seeks to demonstrate how nature, gender and social protest are intricately interwoven in Das’s poetic imagination.

Theoretical Framework and Methodology

This study employs a qualitative textual analysis grounded in feminist ecocriticism, an interdisciplinary approach that examines the intersections of gender, power and ecological representation in literature. Feminist criticism provides tools for understanding how patriarchal structures shape women’s experiences and voices, while ecocriticism foregrounds the symbolic and ethical dimensions of nature in literary texts. Together, these perspectives allow for a nuanced reading of Kamala Das’s poetry that moves beyond purely autobiographical or psychological interpretations.

The methodology involves close reading of selected poems, focusing on imagery, metaphor, tone and narrative voice. Attention is given to how natural elements function symbolically in relation to gendered confinement, emotional alienation and resistance. Secondary critical sources are used to contextualize the analysis within existing scholarship, while the interpretative emphasis remains on original textual engagement.

Nature is treated not merely as environment but as a cultural and emotional construct, shaped by social relations and power dynamics. Gender is approached as both a lived condition and a poetic articulation, while social protest is understood as resistance embedded in language, imagery and emotional truth rather than overt political rhetoric.

Nature and Gendered Identity in “An Introduction”

“An Introduction” is one of Kamala Das’s most anthologized poems and serves as a manifesto of self-assertion. The poem challenges linguistic, cultural and gendered expectations imposed upon women. While its feminist thrust is evident, the poem also relies on natural metaphors to articulate fluid identity and resistance to categorization.

The speaker’s refusal to conform –

“Dress in sarees, be girl / Be wife, they said…”

Here, it is noticed that or it signals a rejection of socially “naturalized” gender roles. The act of wearing her brother’s trousers and cutting her hair becomes symbolic of transformation, echoing natural processes of growth and change. Nature here signifies fluidity, opposing the rigidity of patriarchal norms.

The declaration –

“I am sinner, I am saint, I am the beloved and the betrayed”

This line reflects a multiplicity that mirrors the diversity of the natural world. Just as nature resists singular definition, the female self refuses confinement within fixed moral or social categories. Through this alignment, Das challenges the notion that gender roles are natural or inevitable, revealing them instead as social constructs.

Thus, nature imagery in “An Introduction” becomes a vehicle for social protest, enabling the poet to reclaim identity through metaphors of movement, plurality and transformation.

Marriage, Confinement and Nature in “The Old Playhouse”

In “The Old Playhouse,” Kamala Das offers a powerful critique of marriage as an institution that suppresses female individuality. Nature imagery plays a central role in exposing the emotional violence embedded within domestic life.

The metaphor of the swallow–

“You planned to tame a swallow, to hold her / In the long summer of your love…”

– this line captures the tension between freedom and possession. The bird, traditionally associated with flight and migration, symbolizes the woman’s natural desire for autonomy. The attempt to “tame” it reflects patriarchal control that seeks to domesticate female independence.

Nature here is not romanticized; instead, it underscores the unnaturalness of confinement. The woman’s shrinking sense of self contrasts is sharply with the expansiveness implied by flight and open sky. Das suggests that social institutions that restrict women operate against natural instincts for freedom and growth.

By employing nature imagery, Das critiques marriage not merely as a personal failure but as a social structure that systematically erodes women’s emotional and intellectual agency. The poem thus transforms intimate suffering into a broader social protest.

Domestic Space and Nature in “The Sunshine Cat”

“The Sunshine Cat” presents one of Kamala Das’s most haunting portrayals of marital alienation. The poem depicts a woman confined within a domestic space, deprived of emotional fulfillment and autonomy. Nature appears here in fragments, emphasizing both deprivation and resilience.

The image –

“A streak of sunshine lying near the door like / A yellow cat to keep her company”

– introduces nature into the oppressive domestic interior. The sunlight, compared to a cat, represents warmth, movement and life–elements largely absent from the woman’s existence. This small intrusion of nature highlights the contrast between vitality and stagnation.

Rather than offering escape, nature in this poem serves as a reminder of what is missing. The fleeting presence of sunlight underscores the transience of hope within patriarchal confinement. At the same time, it suggests the persistence of desire and imagination, even in restricted spaces.

Through such imagery, Das critiques gendered power relations without overt accusation. The poem’s protest lies in its exposure of emotional deprivation as a form of social injustice, with nature functioning as a silent witness to female suffering.

Memory, Landscape and Social Change in “My Grandmother’s House”

“My Grandmother’s House” shifts focus from marital relationships to memory and belonging. Nature here is closely associated with the ancestral home, representing emotional security and continuity. The poem reflects on loss – not only personal but cultural.

The house, surrounded by familiar landscapes, symbolizes a nurturing environment that contrasts with the alienation of adult life. Nature becomes a repository of memory, anchoring identity in a past marked by affection and acceptance. The loss of this space parallels the speaker’s emotional displacement in the present.

While the poem does not directly articulate feminist protest, it critiques social change that disrupts emotional and cultural continuity. The erosion of intimate spaces reflects broader transformations that leave individuals – especially women – isolated and rootless.

Nature, in this context, functions as a link between personal history and social evolution. It is reinforcing Das’s broader concern with belonging, lossand identity.

Nature as a Medium of Social Protest

Across Kamala Das’s poetry, nature serves multiple symbolic functions. It represents freedom, confinement, memory, and resistance, depending on context. What unites these representations is their role in articulating social protest.

Unlike overtly political poets, Das embeds resistance within emotional truth. Her protest is not shouted but felt, conveyed through images that resonate with lived experience. Nature provides a language through which private suffering is transformed into collective critique.

Birds signify thwarted or dissatisfied freedom, sunlight embodies fleeting hope, landscapes preserve memory and domestic spaces reveal systemic oppression. Together, these images construct a poetic world where gender injustice is exposed as both personal and social.

Nature, Gender and Sustainability: A Contemporary Reading

From a contemporary perspective, Kamala Das’s poetry can also be read as engaging with questions of sustainability and ethical coexistence. Her portrayal of nature emphasizes relationality rather than domination, aligning with ecofeminist critiques of hierarchical power structures.

By linking women’s oppression with the control of natural spaces, Das anticipates later ecofeminist thought that connects environmental exploitation with patriarchal ideology. Her poetry suggests that liberation – both human and ecological – requires dismantling systems based on possession and control.

Conclusion

Kamala Das’s poetry offers a profound exploration of nature, gender and social protest, revealing how intimate experience can serve as a powerful site of resistance. Through rich and nuanced imagery, she transforms nature into a symbolic medium that critiques patriarchal structures and articulates women’s longing for autonomy, dignity and belonging.

Nature in her poetry is never passive; it is charged with emotional, ethical and political significance. By foregrounding this dimension, the present study expands critical understanding of Kamala Das as a poet whose feminist vision is inseparable from her engagement with nature and society.

Her work affirms that social protest need not be loud to be effective. Through images of birds, sunlight, houses and memory, Das offers a deeply human critique of injustice, making her poetry enduringly relevant in discussions of gender, ecology and social transformation.

Introduction: –

Spider taxonomy is the alpha taxonomy of the spiders, members of the Araneae order of the Arthropod class Arachnidae with about 40,000 describe species. However, there are likely many species that have escaped the human eye to this day and many. The current global list of spider fauna is approximately 42,055 families. The spider fauna of India is represented by 1520 spider species belonging to 377 genera and sixty families. (Chetia and Kalita 2012) describes the identification of the spider assemblages with respect to their diversity and distribution in the semi evergreen forest, Gibbon Wildlife Sanctuary, Assam, India. According to survey the first approach to prepare checklist of GWS. 120 species representing 49 genera under 16 families, 16 specimens were identified till genera. Families indicating excessive member of species are Thomisidae (24 species under 9 genus) followed by Araneidae (22 species under 8 genus), while family Gnaphosidae indicates highest number of genera (10 genera). (Kujur R. and Ekka A. 2016).

 (Gajbe 2016) The spider fauna of Karhandla is being reported for the first time. During some faunal surveys of invertebrates carried out in this region from November 2014 to October 2015, some species of spiders were observed and identified. These spiders are mainly of two types, hunting spiders and web-making spiders.

Family Thomisidae: –

This is large family with more than 3000 known species. 62 are found in this region. They are not active hunters and make more use of camouflage techniques than other spiders. Crab spiders can be found on flowers or leaves of plants. Because they sit on easily spotted places they are also easily to catch by the predator. There eye sight is excellent develop. They have normally to big front eye.

All spiders use their fangs to inject venom; the fangs of many more than 3,500 spider species in the United States are incapable of penetrating human skin. Spiders are rarely aggressive towards humans they bite only in self defense. Spider silk is the strongest fiber in nature, five times stronger than steel, yet so times thinner than human hair. A unique anatomical feature of spider is pedipalps. The two of these appendages positioned just outside the fangs. The male spiders use its pedipalps as miniature boxing gloves, in courtship dance.

Material and Methods: –

The following study of crab spider family Thomisidae is based on morphological characters of crab spider and also phylogenetic analysis of spiders. Through this project and attempt has been made to focus on study of crab spider in.

Study area: –

The Sakri forest is situated about 55Km West of Dhule city at a latitude of 20-59’-28”N and longitude 74⁰-18’.36’’ E.

Sakri forest faces extreme variation in climatic condition with hot summer and very cold winter as well as average rainfall. The annual average rainfall in the forest ranges between 514.1mm to 525mm and temperature ranges between 16⁰C to 31⁰C.

Collection and identification of crab spider species of family Thomisidae: –

            A number of methods are available for collection of spiders from a wide variety of environments. The type of vegetation determines the kinds of spider crab spider (Thomisidae) were collected from the above gardens.

The change in position of the eyes have gone further than in the genus Thanatus, and eyes of the anterior row, with the posterior median pair, from a small compact hexagonal group of which the posterior laterals conspicuously removed. Abdomen is long and cylindrical or cigar-shaped. Legs relatively long, bearing scapulae on both tarsi and metatarsi. These spiders are found in grass and on bushes; when at rest the legs are stretched out longitudinally, two pairs forward and two pairs backward.

Eyes black ringed with chalk white tubercles, lateral tubercles contiguous, ocular quad slightly longer than wide, space anterior median eye a little smaller than posterior medians; both rows strongly recurred. Legs are not very strong, I and II pair longer than III and IV, tibia I and II with two pairs of ventral spines. Abdomen light brown, oval, scattered chalk with patches on the dorsum, four pairs of or regular black patches on the posterior half of abdomen arrange in a longitudinal row, the anterior pair larger and posterior pairs smaller, the anterior half provided with black dots; lateral sides with the deep brown patches, ventral surface uniform pale.

Conclusion: –

            Though good work has been done in India by Sudhirkumar 2005, a pioneering study was conducted to reveal the spider diversity in Mannavan shola Forest in Kerala state, India. Mannavan shola, the largest Shola patch in Asia, exists in “Western Ghats”, one of the biodiversity hot spots of the world. A total of 72 species of spiders belonging to 57 genera of 20 families were collected from this area during this five-day study. But majority of this work is focused traditional taxonomy of the spiders using morphological characters with little or no emphasis on evolutionary or phylogenetic perspectives. Apart from three volumes of ‘fauna of Indian spider’ and spider of India, no other authoritative books exist on Indian spider. The published literature on Indian spider is poor and not easily available in laboratories. Moreover, most of the literature available on internet does not have open access. Most of the keys for identification are poor and fails to identify immature spider. Hence, it is very much difficult to identify the correct spider species.

             The evolutionary study of the crab spider as not yet attempt in India. The modern trends in systematic such as DNA fingerprinting; sequencing has also not yet tested on the spider from India. The present focus of project on the genetic diversity and evolutionary relationship among intra and inter population of crab spider from Sakri region of Sakri, Dhule District.

Introduction:

The experiment of SHG was firstly started by Mysore Resettlement and Development Agency (MYRADA) in India on the basis of SHG development in Bangladesh and after that the movement of SHGs spared all over the India.

The self-help groups have ancient traditions in India historical as well as prehistoric era, there is evidence that such groups existed. Thousands of such groups are operating in rural and urban areas of India. The aim of self-help groups to eradicate poverty and unemployment, establishing such groups on the basis of self-reliance and mutual support rather than waiting for someone else. In India, job creation is a major problem and it is impossible for everyone to get permanent jobs in the organized sector. In India, there are two major types of self-help group’s i. e. Micro finance group and self-help groups.The micro finance groups work in savings and debt allocation while self-help groups do other programs to increase their incomes with regular savings. It mainly works for the production of garments, food processing, and production of products by using local technology. The role of non-governmental organizations or NGOs or similar mechanisms is very important in this type of entrepreneurship. In India, such organizations are doing well in various states.

Therefore, it is imperative to increase their income through self-help groups to increase their family income, increase their living of standards, self-esteem, self-reliance, decision making and fearlessness. Lastly it helps women to become economically, socially and politically empowered through SHGs.

Review of Related Literature:

A. Venkatachalam and A. Jeyapragash (2004) in their work, “Self Help Groups in Dindigul District,” found that the total savings of the SHG members in Dindigul District amount to Rs.622.99 lakhs. The Sangha Loan sanctioned to its members is in tune of 4.3 times of savings. In words, the total amount of Sangha loan sanctioned is Rs.27.20 lakhs. The SHGs in Dindigul District have made a silent revolution for the economic empowerment of poor rural women.

M. Soundarapandian (2006) in his study “Micro Finance for Rural Entrepreneurs Issues and Strategies” made an attempt to analyses the growth of the SHGs and the role of microfinance in developing the rural entrepreneurship. The study suggests that though there is a positive growth rate of the SHGs in states get in terms of growth of the SHGs there is wide variation among states. Linkages of banks with the SHGs are found impossible for this variation.

Ravindra C. Satpute (2012) in his research on“Micro-Finance: A Critical Study of Need, Practices and Future Trends (With Special Reference to Self Help Groups of Amravati District)”, he selected the sample of 400 SHGs in activities like Phenile making, Candle, Agarbatti making, Pickle and Papad making, etc. and found that the maximum number 273 (69.46%) of respondents joined the group for their overall economic development. he further stated that loan amount used by the respondents for domestic purpose, asset building and agriculture respectively. Only 63.07% of the total SHG’s get the benefits from various government schemes.

Objectives of the Study:

1. To analyze the growth of Indira MahilaYojana andSwayamsidha scheme forwomen SHG’s in Maharashtra.
2. To study the socio-economic status of women SHG’s under Swayamsidha scheme in Maharashtra
3. To study the effective support of the government on women SHG’s.

Indira MahilaYojana:

According to the report of director of MAVIM “the Indira MahilaYojana was implemented by the Central Government from 1994 and the MahilaSamruddhi Programme was merged with it and a revised Swayamsiddha Programme was declared for implementation for 5 years from 2001 – 2002 onwards. MAVIM implements the Swayamsiddha Programme in 19 districts and 36 Blocks in Maharashtra. Out of 36 blocks, 21 blocks (old) of Indira MahilaYojana and 15 new blocks were selected. A target of forming 3,500 self-help groups was to be formed by the end of 2006, in 19 districts where the programme operated” and “sauchalayaswere to be constructed with 40% contribution by the members of the village and 60% contribution from Company’s own funds obtained from Government of Maharashtra under Swayamsidha scheme.”

At the end of “March 2005, 3797 SHG groups were formed and 47760women were organised. The women saved `2.42 crores and generated internal lending of `2.34 crores. They obtained bank loans of `87 lakhs. 2237 women started their own business.”

According to the report of MAVIM “at the end of March 2007, 3943 SHG groups were formed and 50,066 women were organised. The SHG members saved `5.70 crores and generated an internal lending of `10.31 crores. They obtained bank loans of `12.65 crores and 17,734 women started their own business.”

Year wise Growth of SHG under Swayamsidhha Scheme of MAVIM

According to the data table (4.7) growth of SHGs were ranged from76.69% to 0.00% during the years 2003 to 2017. The highest ratio of SHGsformed by MAVIM under Swayamsidhha scheme in Maharashtra was into the year of 2004 i.e. 76.69% whereas the negative growth was observed during 2007, 2008, 2010, 2011, 2012, 2014 and 2015 (i.e.-0.53%, -12.90%, -6.09%, -2.65%, -11.66%, -18.92% and -23.47%).

Conclusion

According to the data table it is well seen that the participation of women in economic activities increased and also positively seen their entrepreneurial development in Maharashtra. The number of members does not increase under scheme due to norms of MAVIM. Lastly, we can conclude that MAVIM putting its effort at great extents to upliftment of women and bringing them into the main stream of economic development.

Abstract:

The grief and suffering of those who have been downtrodden and who have become brutal victims of caste prejudice have been captured in works of writing known as downtrodden literature. It is also a potent vehicle for uprising and opposition to untouchability. Instilling a strong resolve to transform society by seizing these marginalized people’s hopes and aspirations, the exploitation of Downtrodden in all spheres of life gives them a strong motivation to do so. Through the analysis of Sharankumar Limbale’s well-known life story The Outcaste, this essay aims to illustrate the picture of suffering and resistance of the oppressed. This essay will also help readers to understand how a Dalit autobiography has developed into a crucial tool for expressing oneself and reclaiming a suppressed sense of selfhood in order to get over the inferiority complex associated with “being a Scheduled Caste.” Through the telling of their stories, downtrodden authors hope to forge a new sense of cultural identity and belonging as well as a place all their own. This literature also demonstrates Sharankumar’s autobiography, “The Outcaste,” as a historical and social narrative that illustrates caste prejudice in society, the deceit of higher caste Hindus, devastating poverty, downtrodden women’s exploitation, and the search for identity.

Keywords:  Caste, Gender, Identity and Marginalization

Introduction:

India has advanced greatly in all spheres of life, but the caste system has persisted there for centuries despite this progress. Despite the fact that oppressed people have existed for generations, they continue to face hostility and are even forbidden from being near Hindus from higher castes. The oppressed are taken advantage of, butchered, kicked, raped, slain, denied minimum pay, and thought to be cursed. Gurram Jashuva accurately captures the plight of the oppressed in Indian culture in his poem “Gabbilam,” in which he expresses his outrage at the crimes committed against the untouchables. According to him, an owl is thought to bring bad luck. However, a downtrodden is not allowed entry inside a temple, while a stray dog can.        

The caste system, which is based on birth rather than ability in India, is totally to blame for the formation of the oppressed in this social arena. The Rigveda’s Purusukta, which explicitly mentions the caste system, is where the word “Dalit” originates. Hindu legend holds that Lord Brahma gave birth to the Brahmans from his mouth, the Kshatriyas from his shoulders, the Vaishyas from his thighs, and the Sudras from his feet. Therefore, Sudras are viewed as the lowest caste—a group of oppressed and marginalized people—while Brahmans are seen as the superior caste. Even Muslims and Christians in India could not avoid the effects of the caste system.

The Marathi dictionary defines the term “Dalit” as having a number of meanings. They are crushed, reduced to pieces, ground, etc. Different regions of India insult Dalits by calling them names like Dasa, Raksasa, Asura, Avarna, Chandala, and etc. The term “untouchable” for members of the lower caste was created by Dr. Babasaheb Ambedkar,. Hindus were referred as the dejected class by the British in 1909. In 1933–1934, Mahatma Gandhi gave them the new name “Harijan”means a child of God, whereas Rabindranath Tagore suggested Hindu upper caste people to call untouchable as an outcaste people. Dr. Babasaheb Ambedkar has given the term Scheduled caste to suppressed downtrodden (untouchable) in our constitution Therefore, entire underprivileged population has been referred as “Scheduled caste” since India became a republic. The oppressed majority often rebels against the rulers’ oppression. Similar to black literature, dalit writings emerged as a protest genre to call attention to all manners of inhumanity. To realize their ambitions and aspirations, to instill a new cultural and social consciousness, to overcome the treatment, humiliation, and caste prejudices in society, to create their own distinct identity.

With Mahatma Phule’s thought, Dr. Babasaheb Ambedkar called for a political movement to bring about balance and offered the untouchables all the rights they had been denied for so long. Writing is a powerful tool for protesting against all types of repression and tyranny. Veteran non-Dalit writers like Rabindranath Tagore, Sarat Chandra Chatterjee, Taru Dutt, Daya Pawar, and others grasp their pens with an egalitarian attitude to speak out against injustice within the servile caste and to raise societal consciousness. Many Dalit authors have written autobiographies to express their traumatic experiences of being oppressed as well as their damaged psyches, including Bama, Sharmila Rege, Narengra Kumar, Jagadhar, Namade Dhanshal, and Sharankumar Limbale. of the Dalit community. Sharankumar Limbale is a writer, editor, critic, Dalit activist, and the creator of 24 books. The essence of Dalit literature is shaped by the life story he tells in his groundbreaking work “Akkarmashi,” which was first published in Marathi in 1984.

In 2003, Santosh Bhoomkar translated his autobiography into English as “The Outcaste.” The fundamental theme of Sharankumar’s work is to establish his mother’s innocence, and he has expertly depicted the misery of his workplace’s irresponsibility. Sharankumar brings up a number of serious points in this book about the caste system and what it means to be a Dalit, but most of his concerns go unanswered.  

Sharankamar Limbale demonstrates in his memoirs how caste prejudice and the associated social stigmatization follow the oppressed everywhere. For them, the moniker “Dalit” turns into a curse. An oppressed person is unable to mingle with Hindu upper castes or move about freely. Sharankumar introduces his readers to the Wani and Brahmin students from the upper castes who used to play their sports apart from the untouchables. The boys from Mahar and Mang have their own games they play among themselves. Caste distinctions were made in the school’s seating layout. The Brahmin and Wani pupils had the front row to themselves in the temple. Seats were set aside lower down in the temple hall for the students from the cobbler community. Hindus from the castes have compassion for the downtrodden  students.

In addition to receiving an education, the downtrodden were assigned the task of collecting dung to cover the walls and floors. The irony is that while the upper castes avoided all contact with the oppressed, they continued to sit on the “baseborn soiled “‘ floor. A disadvantaged person was not allowed within the temple, and there were separate water reservoirs for the various communities. The privilege of using the upstream river to wash their clothes and fill their water containers was reserved for the upper caste. For residential use, the downtrodden gathered water from the river downstream. In the same reservoir, they also used to wash their animals, their clothes, and themselves.

“We are the garbage the village throws out. There were so many caste factions in our school. The umbilical cord between our locality and the village had snapped, as if the village, torn asunder, had thrown us out of it. We had grown up like aliens since our infancy. This sense of alienation increased over the years and to this day my awful childhood haunts me.”(05)

The above cited words suggest the smearing of the hall with dung paste, lighting of the village street lamps, sweeping of the village street, skinning of dead animals, and selling of dead skin are all low-level chores given to untouchables by higher authorities. The upper Caste Hindus in the community pay the Mahar a set amount of grain to carry the dead animal away after it dies. Even while it may seem ironic, it is true that the very animal these people love (in this case, a cow), they detest even touching it after it has passed away.

A person who is oppressed in all facets of life is freed by the caste system. Even the village barber who trims the buffaloes won’t shave a downtrodden head. To get his head shaved, a downtrodden must make a difficult decision. The strap of a Mahar cannot be fixed by the cobblers. The downtrodden have their own sets of cups and saucers that are stored in a tea shop. Latur is a large city in the state of Maharashtra with tall buildings and bungalows, but not a single room is available for rent to a Mahar or a Muslim. The idea of untouchability in Hindu society is contested by Limbale as given below. He says:

“I used clean clothes, bathed every day and washed myself clean with soap, and brushed my teeth with toothpaste. There was nothing unclean about me. Then in what sense was I untouchable? A high caste who is dirty was still considered touchable! This city was made of herds of castes. Even localities were identified by castes.”(107)

As per Limbale, caste prejudice and poverty coexist in a struggling household. Here, Sharankumar Limbale also illustrates two different types of hunger: the need for food and the want for passion. A dejected person typically has to choose between going without food and becoming underfed. A downtrodden is supposedly destined to starve, according to popular belief.

In his child hood Limbale could not control his appetite, so his grandmother ‘Santamai’ would go to the village to ask for some “bhakaris.” His sisters never complained about being hungry, and they go to bed without eating anything. Thus, poor downtrodden were compelled to steal food to fill “the cave of hunger” because they were starving; even they were subject to physical punishment if they caught stealing the food. Consequently, the following quote from Limbale about this topic perfectly sums up his outburst in following  given words, he says:

“Black-marketeers become leaders, whereas those who are driven to steal by hunger are considered criminals.” (Limbale, 21)

The upper castes provided leftover food for the downtrodden. Leftover food is like nectar to downtrodeen. (03) Sharankumar related the story of a school picnic where the Hindus were eating a wide range of dishes while the downtrodden were able to eat only a few dry “bhakaris.” Later, when the caste Hindus’ leftover food was distributed to the Mahar youngsters, they dove in like ravenous vultures. Due of starvation, they consumed rotting, old, and filthy food. Limbale’s grandmother created “bhakaris” out of the grains she salvaged from the animal excrement. These “bhakaris” were difficult to swallow and had an offensive manure odour. The stomach makes you clean crap, and it even makes you eat shit, Limbale declares with justification. (08)

Anyone would be moved to tears by the dreadful poverty in a depressed household. Absolute poverty forced Sharankumar’s family into the vile alcohol industry. Sharankumar and his grandparents used to reside under the bus stand’s squalid surroundings because the bus ridership was their only source of income. The way a prostitute waits for her clients is how they awaited the bus. Under the bus stand’s tin roof, they passed their days and nights. The difficulties they frequently encountered during the wet season are depicted by Sharankumar as given below the words. He claims:

“The village bus stand had large windows, the front almost open. Its roof was made of tin. The rain dripped in through the holes in the roof and drenched us. The chill wind made us shiver. The rain dripped on us throughout the night. Thunder roared and lightening flashed through the wet village…The water becomes streams. In the morning we saw water all over, our village looked as if it had had a bath. Whenever it rained I slept under the bench. Santamai sat shivering in a corner, wrapped in rags. She suffered from rigors. She felt something churn in her stomach.” (Limbale, 51)

Sharankumar Limbale suffers from two social disadvantages as a result of his identity: first, he was born into the Mahar community, and second, he was born out of wedlock. His second identity as an illegitimate kid isolates him from his own community while his Dalit identification distances him from the top classes of society. He is mistreated as a result of being a “keeper’s” child. He considers it inconvenient to enroll oneself in the

school. His illegitimate status prevented him from marrying the woman he loved. He eventually succeeds in marrying a girl, but only after great difficulty. A child inherits both the surname and the identity of his father in a patriarchal society like that of India and the subcontinent. However,  an unborn kid. He stated in given line:

“Why did my mother say yes to the rape which brought me into the world? Why did she put up with the fruit of this illegitimate intercourse for nine months and nine days and allow me to grow in the foetus? Why did she allow this bitter embryo to grow? How many eyes must have humiliated her because they considered her a whore? Did anyone distribute sweets to celebrate my birth? Did anyone admire me affectionately? Did anyone celebrate my naming ceremony? Which family would claim me as its descendant? Whose son am I, really?” (37)

The persona of Sharankumar Limabale is complicated. He criticizes the high caste individuals who cower at the least touch of the oppressed but continue to prey on Dalit women to sate their lustful appetites. Additionally, because of the “unbridgeable divide” between the father and the son, the child born from such an unlawful relationship is denied paternal affection and affiliation. For a parent to give his son his name and standing in this culture, his honor would be on the line.

 “My father lives in a mansion, my mother in a shack, and I on the street,” he says, feeling mentally agitated by his sense of estrangement and rootlessness. Where shall I perish? “Exactly where are my roots?” (62)

Limbale was only 25 years old when he penned this novel. His desire for Identity is stronger when he is younger. He forges a bond with Karna, the fabled son of Kunti. He understands that in this society, a guy can only be identified by his caste, religion, or parent.

He doesn’t really belong anywhere because he lacks both of them. Because his father was from another village, Balsegaon, other boys in Maharwada used to call him “akkarmashi,” which meaning an orphan or a pariah, and he was expelled from the community hall. He could only manage to have the identify of a “akkarmashi” (an unclean or an illegitimate child).

 Sharankumar portrays his grandmother, Santamai, as an elderly woman whose skin ages and becomes dry from exposure to the sun on a regular basis. Her teeth become darker as a result of the usage of herbal powder, and Santamai, who was perspiring, had a blacksmith’s appearance in the light of the stove’s fire. (11)

In their autobiographies, numerous oppressed women writers have expressed their deep emotions in literature. In his memoirs, Sharankumar Limbale conveys his sincere compassion for oppressed women. He also discusses how oppressed women are victimized and marginalized, citing his grandmother and mother as two egregious examples. His Masamai and Santamai are independent women who work outside the home to support themselves. Santamai gets up early in the morning to sweep the village street. And Masamai establishes a home-based liquor business and serves alcohol to the clients.

It’s a curse to be gorgeous in a community of Scheduled Cast people. The high caste Patils has a tradition of creating whores from the Dalit population and having children out of wedlock with oppressed women. He has been forced to choose between the lust and hunger games, and His Masamai is a victim of such persecution. Her home is destroyed by a Patil named Hanmanta Limbale, who also takes her away from her adoring husband and nursing children and keeps her as a “keep” in order to satiate his lust. Later, he abandons her after she gives birth to a child.

She later becomes the concubine of Yeshwantrao Sidramappa, a different Patil from a different village, with whom she had eight children not through marriage. Masamai degrades herself from the status of a wife to that of a whore after getting divorced in order to have a family and provide for them, as a divorced downtrodden

Woman is not permitted to remarry but her divorced husband is permitted to do so numerous times. Limbale very skillfully explains this gender politics in the lines that follow:

“A man can eat paan and spit as many times as he likes, but the same is not possible for a woman. It is considered wrong if a woman does that. Once her chastity is lost it can never be restored.” (36)

Hindus from the upper castes sexually objectify the body of oppressed women. In his writing, Limbale exposes the corruption and hypocrisy of the so-called high caste population as well as the lustful wrongdoings committed by landowners and clergy under the guise of caste and religion. Even to the point of offering his wife to the gloomy darkness of the Patil mansions, a downtrodden man will go. A few Dalit communities have a custom of dedicating a girl child to the gods. These young women spend a significant portion of their lives engaging in ritualistic worship. These women are referred to as “devadasis” (a dancer-prostitute dedicated to the deity and the patrons of a temple). The priest and the kids later have them inked on their thighs.

The downtrodden women frequently experience “rape,” whether the women are victimized by high caste landowners or by their own males. Sharankumar cites the case of Dhanavva, a destitute widow whose father raped her on purpose after her husband’s passing. This arrogant man proudly admits his deed rather than feeling any remorse:

“I have sown the seed from which she has grown as a plant.” Now why shouldn’t I eat the fruits of this plant? (67)

Black people experience the same cruel torture that Toni Morrison depicts in her well-known book “The Bluest Eye,” in which Pecola is sexually assaulted by her own father:

“We had dropped our seeds in our own little plot of black dirt just as Pecola’s father had dropped his seeds in his own plot of black dirt. Our innocence and faith were no more productive than his lust or despair” (5).

Conclusion

As per the above cited words of Author it concludes that the main goal of downtrodden literature is to raise social consciousness among the underprivileged in order to spark a revolution. In fact, Sharankumar Limbale’s autobiography serves as an outlet for his suppressed opposition to the caste system. He paints a negative image of caste prejudice in this book, including its impact on poverty, the search for identity, and the misery of oppressed women. In the same way that black literature addresses the agony and suffering of the Negros, Downtrodden writing carves out a distinct niche for itself by examining the issues and struggles of the oppressed people in their own native tongues.

Sharankumar is a symbol of the community’s overall resilience, which overcomes challenges head-on and emerges with grace at each step. His autobiography’s release has enabled him to successfully revolt against the debased Hindu establishment and its persistent caste stereotypes as well as to forge a depressed sense of self. The autobiography of Sharankumar Limbale is not just an honest account of a single person; it also serves as a narrative about the past and contemporary conditions of the underprivileged community. Consequently, Sharankumar Limbale’s autobiography is a burning explanation as well as a potent representation of an impoverished community in the modern setting.

Abstract

Sustainable development has become an important concern in governance, policy making and legal discussions across the world. The adoption of the Sustainable Development Goals by the United Nations in 2015 introduced a balanced approach to development. It linked economic growth with social justice and environmental protection. India, as a developing country, faces serious social, economic and environmental challenges and also has a major role in achieving these global goals. The Constitution of India reflects values such as justice, equality, liberty, dignity and responsibility towards the environment. These values support the objectives of sustainable development. This paper examines the integration of Sustainable Development Goals with constitutional values in India. It analyses relevant constitutional provisions, Directive Principles of State Policy and Fundamental Duties that promote sustainable development. The study traces the historical development of sustainable development in India. It also highlights how constitutional values provide a strong foundation for implementing the SDGs. Using a qualitative and analytical research methodology, the paper concludes that effective integration of SDGs with constitutional principles is necessary for achieving inclusive and sustainable development in India.

Introduction

Development is seen as an important part of building a nation. This is especially true for countries like India which emerged from colonial rule with poverty and economic weakness. After independence, India focused mainly on industrial growth, economic planning and infrastructure development. The purpose was to reduce poverty and create employment. These efforts did support economic growth. However, they also created serious problems. Environmental pollution increased. Natural resources were overused. Social and economic inequality also increased. Over time, it became clear that development cannot be judged only by economic growth. Growth without social and environmental concern is incomplete. It often benefits a few people and ignores the larger population. This led to the idea of sustainable development. Sustainable development stresses balance. It connects economic progress with social welfare and environmental protection. Its aim is to meet present needs without harming future generations.

At the global level, sustainable development gained recognition with the adoption of the Sustainable Development Goals in 2015 under the United Nations 2030 Agenda. The SDGs consist of seventeen goals. These goals deal with major issues such as poverty, environmental damage, inequality and weak institutions. They are universal in nature. They apply to both developed and developing countries. India is a signatory to the SDGs. It has taken several steps to achieve these goals through laws, policies and welfare programmes. An important point is that many of the ideas behind the SDGs already exist in the Constitution of India. The Constitution was framed to build a society based on justice, equality and dignity. It is not only a legal document. It also acts as a tool for social and economic change. This paper examines how the Sustainable Development Goals and constitutional values in India work together to support inclusive and sustainable development.

Objectives of the Study

The objectives of this research paper are as follows:

1. To examine the concept of sustainable development and its significance in the Indian context.
2. To analyse the constitutional values enshrined in the Constitution of India that are relevant to sustainable development.
3. To study the Sustainable Development Goals from a constitutional perspective.
4. To evaluate the integration of SDGs with Fundamental Rights, Directive Principles of State Policy and Fundamental Duties.
5. To analyse the role of the State in promoting sustainable development in India.

Hypothesis

The hypothesis of this study is as follows:

1. The constitutional values enshrined in the Constitution of India provide a strong foundation for the integration of Sustainable Development Goals.
2. Fundamental Rights like Article 21 support the social and environmental dimensions of sustainable development.
3. Directive Principles of State Policy significantly helps to achieving the objectives of the Sustainable Development Goals in India.
4. Judicial interpretation of constitutional provisions has strengthened the implementation of sustainable development principles.
5. Effective integration of Sustainable Development Goals with constitutional values promotes inclusive and environmentally sustainable development in India.

Research Methodology

This research uses a qualitative and analytical method. The purpose is to study how the Sustainable Development Goals are connected with constitutional values in India. The study is descriptive in nature. It explains the basic idea of sustainable development and important principles of the Indian Constitution. It is also analytical as it looks at how these values support the implementation of the SDGs.

A qualitative approach is used to understand constitutional provisions such as Fundamental Rights, Directive Principles of State Policy and Fundamental Duties. The role of constitutional governance in promoting sustainable development is also discussed. The study is limited to the Indian constitutional framework only. No fieldwork or empirical data has been used. This method helps in understanding the relationship between constitutional values and sustainable development in a clear manner.

Constitutional Values Supporting Sustainable Development

The Constitution of India provides a strong base for sustainable development. The term sustainable development is not directly mentioned in the Constitution. But its ideas can be clearly seen in many constitutional provisions. These values guide the government in achieving development which is balanced in nature. They support economic growth along with social justice and environmental protection. The Preamble of the Constitution sets the main goals of the Indian State. It talks about justice, social, economic and political. It also speaks of equality, liberty, fraternity and dignity of the individual. These values are closely connected with the idea of sustainable development. Social justice aims to reduce inequality and support weaker sections of society. This is necessary for inclusive development. Economic justice focuses on fair distribution of resources and opportunities. Development should benefit everyone and not just a few. Political justice ensures participation of people and transparent governance. This is important for proper implementation of sustainable policies.

Equality is another important constitutional value. Articles 14 to 18 guarantee equality before law and prohibit discrimination. This ensures that people are not denied benefits of development on the basis of caste, gender, religion or economic status. Sustainable development cannot be achieved if inequality continues. Equal participation of all sections of society is necessary. Article 21 of the Constitution guarantees the right to life. The Supreme Court has given this right a wide meaning. It includes the right to live with dignity. It also covers the right to livelihood, health, clean drinking water and a pollution free environment. These interpretations strengthen the idea of sustainable development. They show that environmental protection and human well-being are part of the right to life.

The Directive Principles of State Policy also strongly support sustainable development. They guide the State in forming policies for public welfare. Articles 38 and 39 ask the State to promote social welfare and reduce inequalities. Article 41 talks about the right to work and public assistance. Articles 42 and 43 focus on humane working conditions and decent living standards. Article 47 places a duty on the State to improve public health and nutrition. Article 48A directs the State to protect and improve the environment and to safeguard forests and wildlife. The Constitution does not place responsibility only on the State. It also involves citizens. Under Fundamental Duties, Article 51A(g) makes it the duty of every citizen to protect and improve the natural environment. This includes forests, rivers, lakes and wildlife. This shows that sustainable development is a shared responsibility. Both the Government and the people have a role to play.

Integrating Sustainable Development Goals with Constitutional Values in India

The Sustainable Development Goals were adopted by the United Nations in 2015. They provide a broad framework for development. The goals focus on economic growth, social inclusion and protection of the environment. In India, these goals cannot be achieved in isolation. Their success depends on how well they are linked with the values of the Indian Constitution. The Constitution provides a strong base for this integration. It supports the idea of sustainable development and gives legal and moral support to the SDGs within the country. Many of the SDGs are closely related to the Directive Principles of State Policy. These principles guide the State in matters of social and economic welfare. Goals related to poverty removal, food security, health, education and social security match with Articles 38, 39, 41 and 47. These provisions ask the State to reduce inequality, ensure livelihood, improve public health and provide a decent standard of living. Government welfare schemes on poverty reduction, nutrition, healthcare and education show an effort to connect SDG targets with constitutional duties.

Fundamental Rights also play an important role in this integration. Article 21 which guarantees the right to life has been given a wide meaning by the courts. It includes the right to health, clean environment, safe drinking water and livelihood. These interpretations support several SDGs related to health, sanitation, clean water and environmental protection. By treating these aspects as fundamental rights, the Constitution ensures that development remains people focused and rights based. Environmental protection is an important part of many SDGs. The Indian Constitution strongly supports this goal. Article 48A directs the State to protect and improve the environment. Article 51A(g) places a duty on citizens to protect natural resources. The judiciary has also applied principles like sustainable development, precautionary principle and polluter pays principle. This helps in balancing economic growth with environmental safety. It also protects the interests of future generations.

SDGs related to gender equality and reduction of inequality are supported by constitutional provisions on equality. Articles 14 and 15 guarantee equality before law and prohibit discrimination. Laws and welfare measures for women and weaker sections show the link between constitutional values and SDG commitments. Similarly, SDG 16 focuses on peace, justice and strong institutions. This goal is supported by India’s democratic system, rule of law and independent judiciary. The integration of Sustainable Development Goals with constitutional values creates a complete framework for sustainable governance in India. The Constitution supports the goals of the SDGs and also guides their implementation. It ensures that development takes place with justice, dignity and concern for the environment. For effective integration, there must be proper policies, strong institutions and active participation of citizens. This will help India achieve sustainable development practically.

Challenges in Integration and Implementation

The Sustainable Development Goals are closely linked with the constitutional values of India. But many problems arise in their integration and implementation. One of the main challenges is social and economic inequality. Poverty, unemployment and unequal access to resources are still widespread. Because of this, inclusive and sustainable development becomes difficult. Many marginalised groups do not receive the benefits of development. This goes against the aims of both the SDGs and constitutional justice. Another major challenge is population growth and rapid urbanisation. India has a very large population which continues to increase. This puts heavy pressure on natural resources and basic services. Urban areas are expanding very fast. This has led to unplanned settlements, poor sanitation, pollution and environmental damage. As a result, it becomes difficult to achieve goals related to sustainable cities, clean water and climate action.

Environmental degradation is also a serious concern. Problems like industrial pollution, deforestation, water scarcity and loss of biodiversity still exist. This is so even after having constitutional provisions and environmental laws. In many cases, laws are not properly enforced. Regulatory authorities are often weak. Development projects sometimes move forward without giving enough importance to environmental protection. This affects long term sustainability. Governance issues also create obstacles. There is often a lack of coordination between different institutions. Policies are sometimes fragmented and not properly implemented. While policies may follow constitutional values at the national level, problems arise at the state and local levels. Administrative inefficiency and limited institutional capacity are common reasons for this gap.

There is also a clear gap between constitutional ideals and actual practice. The Constitution lays down strong values. However, turning these values into real outcomes needs political will and sufficient financial support. Public awareness also plays an important role. Many citizens are not fully aware of sustainable development or their constitutional duties. This weakens public participation in governance. To overcome these challenges, a combined effort is required. Policies need to be better coordinated. Institutions must be strengthened. Laws should be strictly enforced. Citizens should also take an active role. Addressing these issues is necessary for meaningful integration of the SDGs with constitutional values in India.

Conclusion

The integration of the Sustainable Development Goals with the constitutional values of India creates a balanced way of development. Both the SDGs and the Indian Constitution aim to create a society that is inclusive and sustainable. The SDGs provide a global direction for dealing with economic, social and environmental problems. The Constitution supports these goals by giving a strong legal and moral base for their implementation in India.

The Constitution of India reflects the idea of sustainable development in many ways. The Preamble, Fundamental Rights, Directive Principles of State Policy and Fundamental Duties promote values like justice, equality, dignity, welfare and protection of the environment. The role of the judiciary is also important. Through interpretation of Article 21, the right to life has been expanded to include health, livelihood and a clean environment. These interpretations strengthen the link between constitutional values and the objectives of the SDGs. They ensure that development remains focused on people and the environment.

Effective integration of the Sustainable Development Goals with constitutional values can help India achieve long term and meaningful development. When policies are framed in line with constitutional principles and people actively participate in governance, development becomes more balanced. It supports economic growth while ensuring social justice and environmental protection. Such an approach is important not only for present needs but also for protecting the rights of future generations.
