Reconnaissance
of the East Coast of Tamilnadu was carried out covering nearly 750Kms so as to
gauge the role of Wetlands in the coastal economy. The entire stretch was
divided into 11 sectors and each sector into units of 10km. The survey was
conducted along the villages on both sides of the road and a few towards the
eastern and western parts. Peoples’ perceptions were obtained through
interviews and other data are recorded by direct field observations. Three
surveys were made in all.
108
Bridges, 737 Culverts 150km of Storm drains were recorded. Nearly 570 water
bodies were noted. The major wetlands include 11 Rivers, 15 Canals, 140 Tanks,
17 lotus Tanks, 70 Backwater areas, 23 Mangrove patches, 575 Aquaculture ponds
and 10 sites of Social forestry. The status of water bodies was poor throughout
the stretch. Four varieties of
water scarcities were detected; Out of 437, 140 villages have both water
scarcity and saline water intrusion. The potable water status was worse to
critical at many places and the seriousness of scarcity was equal at all
sectors. Diversion of run-off into the sea has left many wetlands dry
throughout. These wetlands play a major role in potable water status; its role
is also vital in maintaining the ecological balance of the other critical
Habitats along the Coast and Marine systems.
Besides
the natural changes, the development along the East Coast Road has hiked the
pressure on the coastal systems. The wetlands that are already at critical
stages will get eliminated if left unnoticed, which will increase the
seriousness of the potable water scarcity. Documenting ecology of the entire
coast is necessary for its conservation and Development. A suitable blue print
for action for the East Coast on Potable water, Conservation and developmental
awareness is likely to emerge from our Preliminary work.
