better water management
say there isn't a shortage of water. The problem is caused purely due to
you look at the pattern of rainfall, you realise that it's been
more or less the same over the years. We have sufficient water, but we
don't know how to conserve this water. Nobody has employed the ecosystem
approach that should be used in water management. The earlier concept of
tanks isn't followed by the present generation either.
would you say is the cause for the present problem?
problem with the Western Ghats is encroachment and its conversion
into an agricultural area. Initially, there is productivity but this
comes down and people leave and move on, turning it into barren land.
Lakes are silted, encroachments aren't maintained and people have
removed the vegetation.
do you suggest the eco-system be managed?
is an urgent need to restore and conserve the actual source of water.
Take for example a lake or river basin. The cachement area should be
maintained. One should, make sure that there is no barren land in
the catchment area. Also,
if you part with good vegetation you have contaminants coming in
to the water.
the imal solution?
one river belongs to many agencies, as a result there is no co-ordinated
action. We have to restore the eco-system by removing all encroachments.
The solution is the development of something similar to a Lake
Development Authority that's given full power to manage the eco-system.
This team should take up restoration work. The river basin should be
treated as one unit and all should be made stakeholders.
