Metro Region Concept

 A metropolitan area (metropolis) is a region consisting of a densely populated urban core and its less populated surrounding territories, sharing industry, infrastructure and housing. A metro area usually comprises multiple jurisdictions and municipalities, neighborhoods, townships, boroughs, cities, towns, exurbs, suburbs, counties, districts, states and even nations. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions. Metropolitan areas include satellite cities, towns and intervening rural areas that are socioeconomically tied to the urban core, typically measured by commuting patterns. 

At first, the ‘metropolitan district’ was used in 1910 in the Census of Population carrying a central city of 50,000 or more population and all adjacent minor civil divisions having a population density of 150 or more persons per square mile. By 1940, the concept of the metropolitan district had lost favour because the possibilities of correlating local data with district data were limited. 

Besides this, the metropolitan district did not truly represent social and economic integration with the central city. Therefore, a new areal unit, the standard metropolitan area, came into vogue in 1949. It was defined as made up of counties instead of minor civil divisions. It was succeeded by the ‘Standard Metropolitan Statistical Area’ (SMSA).It is defined below as it existed in 1970. 

A contiguous county will be included in an SMSA if: 

(a) At least 75% of the resident labour force in the county is in non-agricultural labour sector 

(b) At least 30% of the employed workers living in the county work in the central county or counties of the area. 

A contiguous county which does not meet the foregoing requirements will be included in an SMSA if at least 75% of the resident labour force is non-agricultural and meets two of the following additional criteria of metropolitan character and one of the following criteria of integration. 

(i) Criteria of Metropolitan Character 

(a) At least 25% of the population is urban. 

(b) The county had an increase of at least 15% in total population during the period covered by the most recent two censuses. 

(c) The county has a population density of at least 50 persons per square mile. 

(ii) Criteria of Integration 

(a) A least 15% of the employed workers living in the county work in the central county or counties of the area, or 

(b) The number of people working in the county who live in the central county or counties of the area is equal to at least 15 per cent of the employed workers living in the county, or 

(c) The sum of the number of workers commuting to and from the central county or counties is equal to at least 20% of the employed workers living in the county.

As stated above it seems that metropolis is primarily a demographic concept. But this may be emphasized once again that metropolis is much more than an agglomeration. It possesses distinct character and functions which are not likely to be found either in agglomeration or in conurbation. In metropolitan cities each function has benefited from the conditions which brought about the other functions and has found reasons for developing there itself. 

There the powers of attraction make them bigger and bigger, and consequently enormity of their size increases their power of attraction. This is happening in Mumbai which has grown tremendously during 1901-1991 by 1000 times. Mumbai has simultaneously an international port, one of the biggest commercial marts, an important industrial node of the country and a cosmopolitan centre. After analyzing the conditions of this development, it may be observed that out of 300 cities with population over one million in the world (1991), more than 50% are sea ports. In reality, ports possess immense potentials to concentrate functions, because, on the one hand, they are by definition commercial places, and on the other, they attract manufacturing industries by the materials of all sorts which they receive from various parts of the country. 

Even in the days of the ancient Mediterranean civilizations, and also, during the colonial times, the great commercial connections were then maritime links with the metropolis. The eastern and western sides of the Atlantic in Europe and America therefore, have great ports. Metropolitan cities acquire a sort of permanence and remain evergreen over time.

Metropolitan Cities in India 

The Constitution (74th Amendment) Act, 1992 defines a metropolitan area in India as, an area having a population of ten lakhs or more, comprised in one or more districts and consisting of two or more municipalities or panchayats or other contiguous areas, specified by the Governor by public notification to be a Metropolitan area. 

In India, the Census Commission defines a metropolitan city as one having a population of over four million. Delhi, Mumbai, Kolkata, Chennai, Hyderabad, Bangalore, Ahmedabad, Pune, Surat and Nashik are those Indian cities that have over 4 million people. For these million plus cities the Census definition of an urban agglomeration requires that it should be a continuous urban spread constituting a town and its adjoining urban growths or two or more physically contiguous towns together with adjoining outgrowths. 

There are 53 urban agglomerations in India with a population of 1 million or more as of 2011 against 35 in 2001. As per the preliminary results of the Census 2011, released by the Registrar General of India, Greater Mumbai with a population of 18,414,288 continues to be India’s biggest city, followed by Delhi – 16,314,838 and Kolkata- 14,112,536. These three cities are India’s mega-cities with 10 million plus population. But, when we consider Urban Agglomeration as an extended city comprising built up area of central core and any suburbs linked by continuous urban area, we have a change at the top. Delhi NCR, with the inclusion of Gurgaon, Faridabad, Noida and Ghaziabad becomes the No.1 urban agglomeration with a population of 21,753,486, ahead of 20,748,395. 

As of 2011 census of India, there are 46 metropolitan cities in India and the top ten are, Mumbai, Delhi, Kolkata, Chennai, Hyderabad, Bengaluru, Ahmedabad, Pune, Surat and Visakhapatnam.

Water and No Water: Wastage, Shortage and mismanagement.

Mumbai is facing a shortage of water with a third of its residents not having drinking water as per a recent report. This comes in heels with the news of massive water-logging across the city and flood-like situations. This is reminiscent of the Chennai Water Crisis in 2019 when a flood had hit the city in 2018 and in May 2019, the city declared a zero-water day – no water left in any of its reservoirs. As per statistics, in the coastal city with a medium size river flowing right through it (the famed Anna University is actually partially built on lands claimed from the river), 60% of its population relies on bottled water for drinking all year long. Was this always the case? History suggests no. But it has been so for about a decade now. This is not very shocking given that Mawsynram, the place with the highest recorded average rainfall on the planet also faces water shortage during summers!!!

A lot of rain, and yet no water to drink

Yemen – the poorest of Arab nations and a region marred by civil war and international interference for more than a decade now might also have the root of its civil war as water shortage. Let us understand that the Yemeni factions are the Houthis, the republicans – with both basically supporting their tribal interests – and a swinging group of Saudi-led forces. Records suggest that there existed blood feud between villages just because a village constructed a well very close to that of the other village. As per data, Yemen has the least water availability per capita on the planet, even inviting statements like – if water were to get exhausted on Earth, this process would begin in Yemen. This is odd, given the fact that Dubai is a sprawling metropolis situated in the same Saudi desert.

Yemen is the most water depreciated nation on the planet.

The situation is actually grim in many more places – Northern India – a land abundant with rivers and lakes – most of them, technically all of them polluted beyond potability. Go to Africa and the nations with rainforests and rivers are dry.

What is the cause then? We often hear of climate change. A reader would agree about the reality of climate change but would certainly not let go of the sheer amount of mismanagement involved in the handling of water resources. Governments all over the world have tried in their own way to clean water bodies – the money ending up in their coffers owing to balant corruption. In India, for instance, the Save Ganges Movement or ‘Ganga bachao abhiyaan’ in the vernacular has been a project spanning over three decades and costing lakhs of crores – the best part – to no result. NGOs and villagers have often revived water bodies across the planet showing the importance of public participation in government or local initiatives. But, the people aren’t really very concerned about this issue it seems. It might find itself in discussions during summers or in newspapers – but people refuse to consider it as a problem as grim as climate change. No one can imagine the change Chennai saw with themselves.

Chennai’s water crisis- Natural or man made?

Chennai, the capital city and heartthrob of Tamil Nadu observed ZERO DAY on 19th June, 2019 when there was no water left in all the four reservoir tanks built in the city. Chennai is a city located on southeast coast of India serving as a gateway to the magnificent South India with the Bay of Bengal surrounding it on one side, the city is intersected by three rivers. How come that the city which has “abundant of water bodies” becomes dry. Read this blog to know how the water crisis in Chennai is a result of man’s selfish actions and is a warning giving a hint of what the nature holds for us in future if we degrade it.

Causes of water scarcity in Chennai

Chennai is situated on the south east coast of India and receives majority of its rain during winters because being situated on the south east coast, it lies on the leeward side of the Western Ghats preventing the south west monsoon winds which originates in the Arabian sea on the west coast of India to shed its rain there during summers when generally rest of the country experiences monsoon. Thus it gets majority of its rain from retreating southwest monsoon winds and northeast winds during the months of December and January. The rest of the months the city has to rely on occasional rains and mainly on the reserved water which is scarce in Chennai.

Owing to Urbanisation and construction on the bodies which once were the catchment and flood relief basins, the space required to hold the rains is now blocked. The very suitable example being the very famous IT corridor of Chennai which is built on 230 square kilometers of marshland , has reduced the area of the places to hold the precipitation which occurs during its monsoon. Moreover with the rise in the number of Industries , the water bodies in Chennai are highly polluted. Though the industrialization resulted in Chennai being called “The Deteroit of India” due to the vast automobile sector established there housing the scions such as the Tata motors, the neglection of the authorities in maintaining the precious water bodies resulted to Chennai experiencing the ZERO DAY.

Chennai receives rain on an average of 54 days per year with a minimum average of 140 centimeters of rainfall which is enough for the survival if the water is properly harvested but it is the inability to collect and reserve the rain water which led to the MAN MADE water crisis. Between 1893 and 2017 the area covered by the water bodies is reduced from 12.6 square kilometers to 3.2 square kilometers. As reported by The Diplomat, NITI Aayog  predicted in June that 21 Indian cities would run out of groundwater in 2020. A report by the London-based risk analytics firm Verisk Maplecroft named Chennai as facing an “extreme risk” of water stress, saying its present crisis “could be the new normal for tens of millions of people” in India’s urban centers.

Since there is no enough reserved water for the heat days which comes in June and the water remaining in the water bodies is either too saline or too polluted to be fit for use, Chennai has to rely on the tanks which carry water from hundreds of kilometers far away to satisfy its water needs. As suggested by the various reports , there is 85 percent decline in Chennai’s groundwater levels.

Actions taken by the Government to prevent

  • Chief Minister of Tamil Nadu Edappadi Palaniswami , after that dreadful day in June 2019, announced a public program including maximum participation of women covering everything from rainwater harvesting to water saving and recycling to the protection of water bodies and a massive study on how to clean the polluted rivers. Until the research and the plan is completed , the government decided the construction of desalination plants in the city which though costly will help in a great way to solve Chennai’s water problems until the natural water bodies are restored, by desalining the sea water making it fit for domestic and industrial use. The plan is however still in the initial process as there are many protests regarding how it will cause environmental damages and intense loss to the local fisheries.
  • The past always comes to the rescue. Supported by the Asian Infrastructure Investment Bank and the Dutch Government , the Greater Chennai Corporation has started an initiative called “the city of 1000 tanks” which aims at restoring the tanks near the temples and making it the reservoirs for storing the rain water just like in the past and building new tanks too surrounded by green slopes to help catch the rainwater and increase the groundwater level.

The state of Tamil Nadu of which Chennai is the capital has predicted in its climate action plan that the annual temperature of the city will raise by 3.1 degree celsius by 2100 from its original level of what it was in 1983 and 2000s with the annual rainfall falling by 9%.Further , the little rainfall which the city experience in June and September which was enough to refill the reservoirs and maintain the growth of crops will decrease while the winter rainfall will increase causing more floods and droughts.

The condition which Chennai is facing can be taken as a threat issued by nature to not degrade it else the consequences can be severe. The day is not too far when the rest of the world may also experience what Chennai is , if the present practice continues and that day will lead to our downfall.
