Wetlands need to be reinforced as more than just open sources of water. How they are identified and conserved requires a rethink

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.
