DOOMED TO DIE |

Wetlands in India are dying
at a frightening pace, says the Salim Ali Centre for Ornithology and Natural History,
(SACON), a Coimbatore-based research insti-tute. We have lost almost 3 lakh (about 40 per
cent) inland lakes and ponds in the past 10 years!

Wetlands. They are water bodies and
marshesfound in mountains or river basins. In cities, valleys and deserts. India
once had many, many of them. They were called by different names. Talab in
Rajasthan and Uttar Pradesh, pukur in West Bengal and Bihar; and eri in
Tamil Nadu. People drank water from them and bred fish. They acted like water cushions
after heavy downpours, and prevented floods. They also recharged the water table under the
earths surface. So they were nurtured with care by those who lived around them. But
not any more. States now seem to consider these as "wastes" or non-productive
units of land, says SACON. So they are either turned into dump yards to dispose sewage and
solid waste; or they are filled up to make way for new constructions! The news is even
worse than you think. A similar study was conducted 10 years ago by the Ahmedabad-based
Space Application Centre (SAC). But it was done in a smaller scale, taking into account
only the larger wetlands (covering 56 hectares or more). SACON spread its net much wider,
and surveyed all wetlands from 2.25 ha to more in size. And still the total number
recorded by SACON is less than that counted by SAC!
What price?
Consider the scale of the damage:
Ladakh has lost 87 per cent of its
wetlands;
Madhya Pradesh has lost 35 to 86 per
cent;
Surendranagar and Sabar-kantha in
Gujarat lost about 78 to 94 per cent, while in Jalore and Jodhpur of Rajasthan the loss is
95 and 89 per cent;
Cuddalore in Tamil Nadu lost about 90
per cent.
Now, let us take stock:
SACON says the demise of lakes has
affected 69.25 to 73 lakh people, who used these for their various needs;
Ecosystem service value of a wetland,
that is, its contribution in providing livelihood and sustaining the planets
ecological balance is Rs 6.65 lakhs per hectare almost seven times higher than that
of forest (Rs 90, 000 per ha)!
