The ecologically subsidised city: on Kolkata's wetland communities

If ever there was someone who lived true to his name, it was Dhrubajyoti Ghosh. In Sanskrit, “Dhrubajyoti” refers to the light (jyoti) emitted by the pole star (dhruva tara). The ecologist, who passed away in February, was unwavering in his commitment to the cause he lived for and fearlessly defended: saving the ecologically critical East Kolkata Wetlands from the greed of developers for almost four decades, right up until his passing away.

Rural ecological wisdom

What Ghosh discovered serendipitously, as a public sanitation engineer in the early 1980s, was that Kolkata’s wastewater is introduced into and detained in shallow waterbodies (bheris in Bengali) which serve as oxidation ponds because of the presence of algae. Under the open tropical sun, the water undergoes change, getting comprehensively treated and cleaned as the bacteria disintegrate and the algae proliferate, serving as food for fish. The treated water is used by villagers in the area to grow vegetables and paddy.

The beauty of what Ghosh discovered is that these villagers have been following such sane ecological practices for many decades without any help from the State, and well beyond the gaze of the media. It suggests remarkable ecological wisdom on the part of largely illiterate villagers, based on knowledge of local conditions and wetland hydrology.

Thanks to his dedicated work, the 125 sq km area of the wetlands were recognised internationally in 2002 as a ‘Ramsar site’, or a wetland of international significance, which made it incumbent by both the State and the Central governments to protect them from invasive encroachments.

To the untrained eye, wetlands are easily and frequently mistaken to be wasteland, a point of view that shows remarkable ecological ignorance. Greater Kolkata, with a population of more than 14 million people, is one of the largest metropolitan areas in the world. A growing population of this size in a developing economy puts huge pressures on the infrastructure, sanitation being foremost among them.

Nature at work

Kolkata is fortunate to be home to the world’s largest organic ‘sewage treatment plant’, the wetlands. Unobserved by the rest of the world, sun-fed algae and the bacteria in the sewage perform this wondrous function.

A conservative estimate of this great service being performed quietly by nature would give us this data: the capacity to treat 750 million litres of wastewater per day. In monetary terms it would be over $25 billion (₹162,500 crore) annually.

But this is only one part of it. These wetlands are also home to a wide variety of aquatic life, vegetation, and hundreds of species of birds. Moreover, after nature’s organic treatment, the sewage that drains into the wetlands results in 55,000 tonnes of vegetables and paddy and 10,000 tonnes of fish annually, giving a community of 100,000 people a livelihood. In effect, the wastewater works as a costless fertilizer to produce cheap food for what Ghosh called an “ecologically subsidised” city.

Because these invaluable benefits cannot be calculated, they are often brushed aside in the calculations of developers. No textbook of development economics in India or elsewhere talks about “the developer’s model of development”, the one that is actually the dominant understanding of development at work across 21st century India.

In 2005, the UN Millennium Ecosystem Assessment found ecological degradation to be more prominent within wetlands than any other ecosystem on Earth.

Dhrubajyoti Ghosh recognised this and did more than perhaps any other individual in creating public awareness in India about the need to conserve its wetlands. His efforts were recognised internationally, when he was named, in 1990, as a UN Global 500 Roll of Honour laureate. In 2016, he received the prestigious CEM Luc Hoffmann Award from the International Union for Conservation of Nature.

Ghosh was an ecologist, not an environmentalist. Based on his close observations of wetland communities and their organically renewable livelihoods, he argued for several new concepts relevant to ecological pedagogy and policy-making. For him, the environment was not a mere after-thought in the operations of a market economy; and the forgotten natural world was no mere ‘resource’. Such a perspective illustrates the holistic quality that an ecologist brings to his vision and work. Ghosh was that sort of a man.

Missing the wetlands for the water

The government is all set to change the rules on wetlands. The Draft Wetlands (Conservation and Management) Rules, 2016, which will replace the Wetland (Conservation and Management) Rules of 2010, seek to give power to the States to decide what they must do with their wetlands. This includes deciding which wetlands should be protected and what activities should be allowed or regulated, while making affable calls for ‘sustainability’ and ‘ecosystem services’.

On the face of it, this appears to favour decentralisation and federalism. But the peculiar reality of wetlands shows that local pulls and pressures are not the best determinants for their protection. Both water in liquid form and wetlands in the form of ‘land’ are hotly contested, making wetlands the most imperilled natural ecosystem worldwide. It is imperative that the Draft Wetlands Rules, 2016 (comments for which close today) be looked at with a hard, if not cynical, eye. Three issues are of immediate concern. First, the draft does away with the Central Wetlands Regulatory Authority, which had suo moto cognisance of wetlands and their protection. Second, the draft rules contain no ecological criteria for recognising wetlands, such as biodiversity, reefs, mangroves, and wetland complexes. And finally it has deleted sections on the protection of wetlands, and interpretation of harmful activities which require regulation, which found reference in the 2010 rules.

Experiments with water systems

One of the biggest ironies around water is that it comes from rivers and wetlands, yet it is seen as divorced from them. While water is used as a resource or good, public policy does not always grasp that it is part of a natural ecosystem. Efforts at engineering water systems are thus efforts at augmenting water supply rather than strengthening the capacities of ecological systems. There have been many recent attempts at this sort of engineering — Karnataka had dredged its rivers, for instance; other States may follow suit. The Ken and Betwa rivers in Madhya Pradesh are to be interlinked, and we have a history of building dams and barrages to store water. Parliament has already passed a Waterways Act, which will make navigation channels of 111 rivers, by straightening, dredging, and creating barrages.

While these projects require serious ecological consideration, they are usually informed only by the need to ‘use’ water. For instance, river dredging may increase the capacity of a river channel, but can also interfere with underground reservoirs. Over-dredging can destroy these reservoirs. River interlinking changes hydrology and can benefit certain areas from a purely anthropocentric perspective, but does nothing to augment water supply to other non-target districts. Constructions of barrages have impacts on ecosystems and economies: the commercially important hilsa fish are no longer found in the Padma river after the construction of the Farraka barrage across the Ganges.

In the case of wetlands like ponds, lakes and lagoons, the contestations are more fierce. Who owns the wetland is a common quandary — and what happens to the wetland also depends on this. Asia’s largest freshwater oxbow lake, the Kanwar lake in Bihar, has shrunk to one-third of its size due to encroachment, much like Jammu and Kashmir’s Dal lake. Water sources like streams, which go into lakes, also get cut off, as is the case of lakes in Bengaluru and streams in the Delhi Ridge. The political pressure to usurp water and wetlands as land is high — and for this reason, States have failed to secure perimeters and catchment areas or notify wetlands.

Why then do the Draft Wetland Rules award full authority to the States? The particularly complex case of wetlands warrants more checks and balances. In the proposed scenario, with an absence of scientific criteria for identifying wetlands, it is imperative to have a second independent functioning authority.

What comprises a wetland is an important question that the Draft Rules leave unanswered. Historically, as wetlands did not earn revenue, they were marked as ‘wastelands’. While the Wetland Atlas of India says the country has 1,88,470 inland wetlands, the actual number may be much more: U.P. itself has more than one lakh wetlands, mostly unidentified by the government.

Significantly, the 2010 rules outline criteria for wetland identification including genetic diversity, outstanding natural beauty, wildlife habitats, corals, coral reefs, mangroves, heritage areas, and so on. These criteria would refer to wetlands like Pulicat in Andhra Pradesh which have nearly 200 varieties of fish.

The Ramsar Convention rules are the loftiest form of wetland identification that the world follows. Ramsar has specific criteria for choosing a wetland as a Ramsar site, which distinguishes it as possessing ‘international importance’. An important distinguishing marker is that Ramsar wetlands should support significant populations of birds, fish, or other non-avian animals. This means that it is ecological functioning which distinguishes a wetland from, say, a tank, which is just a source of water. However, man-made tanks or sources of water can also evolve into wetlands. For instance, Kaliveli tank in Tamil Nadu, an important bird area, is fed by a system of tanks and man-made channels forming a large and vibrant landscape. A wetland is more than a source of water, or a means for water storage, though it is often reduced to only that. By removing ecological and other criteria for wetland identification and protection, and the examples of activities that could hamper this physical functioning, the new draft underlines the same malaise which misses the wetlands for the water.

Use and non-use

While the new draft calls for sustainability, this is a difficult concept to enforce, particularly with regard to water. Regulation of activities on a wetland and their “thresholds” are to be left entirely to local or State functionaries. There are insufficient safeguards for the same, with the lack of any law-based scientific criteria or guidance. For instance, it is telling that regulation of activities in the draft rules do not make any obvious connection with existing groundwater legislations because these two aspects are still seen as separate.

The 2016 Draft Wetland Rules also call for wise use of wetlands. ‘Wise use’ is a concept used by the Ramsar Convention, and is open to interpretation. It could mean optimum use of resources for human purpose. It could mean not using a wetland so that we eventually strengthen future water security. It could also mean just leaving the wetland and its catchment area as is for flood control, carbon sequestration, and water recharge functions.

Finally, in a country which is both water-starved as well as seasonally water-rich, it is not just politics and use that should dictate how wetlands are treated. Sustainability cannot be reached without ecology. Towards this end, our wetland rules need to reinforce wetlands as more than open sources of water, and we need to revise how wetlands should be identified and conserved.

Reconsider the Rules: on 2017 Wetland Rules

Earlier this year, a judgment by the Uttarakhand High Court, stating that Ganga and Yamuna rivers are “living entities”, captured the national imagination. It is worth noting that wetlands, the other major water-based ecosystem apart from rivers, are at a moment of policy transition in the country. This year, a new legal framework for wetlands was passed, the Wetland (Conservation and Management) Rules, 2017, replacing the earlier Rules of 2010. Also this year, the Supreme Court passed an order directing States to identify wetlands in the country within a stipulated timeframe.

Going forward

The 2017 Wetland Rules have been criticised for doing away with strong wetland monitoring systems and omitting important wetland types. At the same time, the Supreme Court order directs States to come forward and notify wetlands. What then could be the way forward?

The 2010 and 2017 Rules for wetlands both emphasise that the ecological character of wetlands ought to be maintained for their conservation. ‘Ecological character’ refers to processes and components which make the wetland a particular, and sometimes unique, ecosystem. For example, as lagoons like Chilika (Odisha) and Pulicat (Tamil Nadu/Andhra Pradesh) are characterised by a mix of saline and fresh water, the flows of each type need to be maintained; river flood plains contain wetlands that require conservation so they can re-fuel the river with fish and other aquatic life during flooding.

In the 2010 Rules, some related criteria were made explicit, such as natural beauty, ecological sensitivity, genetic diversity, historical value, etc. These have been omitted in the 2017 Rules. There are a few reasons why this is problematic. First, there is multiple interest around wetlands. Multiple interests also have governance needs, and this makes it absolutely necessary to identify and map these multiple uses. Leading on from this, and second, it is crucial to identify ecological criteria so that the wetlands’ character can be maintained. The key to wetland conservation is not just understanding regimes of multiple use — but conserving or managing the integrity of the wetland ecosystem. Finally, restriction of activities on wetlands will be done as per the principle of ‘wise use’, determined by the State wetland authority. Whether wise use will include maintaining ecological character remains to be seen. Under the new Rules, no authority to issue directions, which are binding in nature to desist from any activity detrimental to wetland conservation, has been prescribed to State wetland authorities.

Salt pans are an example how one use (of making salt) has trumped the other (of environmental balance). Salt pans as ‘wetlands’ have been omitted from the new Rules. They were identified as wetlands in the 2010 Rules, as they are often important sites of migratory birds and other forms of biodiversity. The omission in the 2017 Rules suggests that while saltpans do exist as wetlands, they do not require any conservation or ecological balance. The inference can also be that it would be acceptable to tip the environmental balance or integrity of such a wetland, which could lead to damage and pollution.

The case of Deepor Beel

The issue of wetlands being multiple-use areas — and subsequently being abused due to clashes of interest — found centre-stage this year with the observations of the National Green Tribunal (NGT) in the case of Deepor Beel.

Deepor Beel is a Ramsar site and a part of it is also wildlife sanctuary in Guwahati, Assam. (‘Ramsar Sites are designated because they meet the criteria for identifying wetlands of international importance.’) This wetland harbours a wide variety of biodiversity, and also suffers from intense man-made pressure — the city’s municipal waste is dumped close to the Beel. Large, meat-eating storks (Greater adjutant storks) are ironically found eating from the mountains of garbage at the site. Potential impacts of contamination or poisoning from the garbage are still unknown. This January, 26 storks died. The fact that Deepor Beel (Beel means water body) exists as a wetland does not prevent garbage dumping; this is a fate faced by many wetlands. The NGT’s observations on Deepor Beel are interesting and symptomatic of what is happening in several wetlands. In an inspection done by the judicial member of the Tribunal, it was noted that waste was being dumped “not beyond the site but within it,” and “demarcations are made by drying out areas or cutting off water sources”. These are classic ways of killing a wetland and turning it from a wet to a dry ecosystem; or from a lake to a garbage dump or cesspool. The Tribunal has now asked for the “traditional” spread of the wetland.

Given all the modern uses of wetlands, or the use of the wetland only for its land, looking at traditional cartography may be one way to understand catchments of wetlands. It may also be a way of restoring some modicum of ecological character, identity or ‘rights’ to wetlands, as the river judgment suggested. There are challenges ahead in identifying wetlands – multiple and competing use is just one of them. Understanding the historic spread and ecological character will be an important bulwark for the way forward. Setting clear governance systems would be the next. Without either, we are looking at a complete dilution of wetlands in the country.

Citizens for waterfowl: on the urgent need to save wetlands across India

Every winter, the thousands of wetlands that dot India transform from muddy slips of water to raucous bird parties. Ducks and geese from Ladakh and Tibet swim through aquatic vegetation, waders on stilt-like legs forage for grubs on squelchy, half-submerged banks, and sinuous Oriental darters spear the water for fish.

The two-week Asian Waterbird Census (AWC) that surveys sites across 25 countries in Asia and Australasia, including India, began last month.

While the data is still pouring in from this huge citizen science initiative, the census over the years has pointed to some clear trends. India has the biggest species diversity among the regions sampled by AWC. The survey tallied a mean figure of 1.8 million waterbirds over 300 sites in the country between 2008 and 2015.

Odisha’s lagoon, Chilika Lake, they found, supports a staggering half-a-million waterbirds. Many of the waterbirds that winter in India’s wetlands are of course migratory: like the bar-headed goose, which breeds in Mongolia, Tibet and Kyrgyzstan and crosses the Himalayas and Hindu Kush to reach India.

Decline in species

But the picture isn’t all rosy. There has been a notable decline in several species: the Oriental darter, better known as the snakebird for its long neck, which was once a common sight in many wetlands, numbered just 4,000 in the sites surveyed. The Indian skimmer, with a bright orange bill — the lower mandible longer than the upper one so it can ‘skim’ over water to snap up fish — were just 300. As for the sarus crane, the world’s tallest flying bird, often found in pairs or small groups near wetlands, only 100 birds were found in several years.

But wetlands, cherished equally by local residents, birdwatchers — and real estate developers — are in peril. The National Wetland Atlas, prepared by the Indian Space Research Organisation in 2011, found that India has over 2,00,000 wetlands. But a vast majority had not been notified as wetlands thus running the risk of being destroyed.

The many cases being heard right now in courts across the country reflect the wetland’s precarious existence.

In Delhi-NCR, birdwatchers have filed a case to protect the Basai wetland, which is fed by sewage but continues to harbour almost 300 bird species. A similar case was recently filed to conserve Najafgarh jheel, a riverine wetland in Haryana. Kolkata’s iconic East Kolkata Wetlands, designated a Ramsar wetland of international importance, is being steadily eaten up by construction, and a case has been filed with the National Green Tribunal. This wetland, like many in and around cities, plays an important civic role: it acts like a giant sieve for the city’s sewage, thanks to the fish and aquatic vegetation.

What’s not a wetland

Committees are also examining the condition of Sukhna Lake in Chandigarh, Deepor Beel in Guwahati, and the lakes in Nainital, all choked by sewage, garbage and encroachment. To make matters worse, the new legislation for wetlands, the Wetland (Conservation and Management) Rules 2017, unlike the Wetland Rules of 2010, implies that manmade waterbodies (such as tanks) and salt pans are not wetlands. In reality though, salt pans and tanks not only support birds both in coastal and peri-urban areas, they are also an essential part of the local cultural fabric.

“A simple assessment of (bird) count information indicates that several waterbird populations in the Central Asian flyway (comprising migratory routes) are declining. Urgent national and regional action is needed to reverse this trend,” says Taej Mundkur, Regional Coordinator of the AWC with Wetlands International.

While hundreds of wetlands in India are in need of identification and notification, at the Conference of the Parties to the Convention on the Conservation of Migratory Species of Wild Animals last year, the Central government offered to consult with other countries to operationalise the Central Asian Flyway Action Plan to Conserve Migratory Waterbirds and their Habitats.

The action plan hopes to reduce threats to waterfowl and conserve wetlands while also tackling threats such as power lines and windmills. This plan is now being created with civil society and other experts. “It should be recognised that better management of our productive wetlands for waterbirds also provides a wide range of benefits to people. So it is a win-win situation,” says Mundkur.

Yet, one thing is clear. While wetlands are clearly in legislative, administrative and physical peril, the citizens of India are standing up for them. The AWC, a simultaneous and widespread count over two continents, would not be possible without the active involvement of citizens. This effort — coming from nature lovers, forest departments, and networks like the Indian Bird Conservation Network — harnesses the spirit of volunteerism. And the observations of these intrepid citizen scientists, who count birds year after year, sometimes in places that are dismissed as nothing more than a sewage line, give hope to the world’s waterfowl that today must cross both geographical and metaphorical mountains.
