catchment treatment, but again this has declined
in 2004–2005. There is an increase in open forest
area in 2004 and decrease in degraded forest
which again shows that deforestation activities
have become less and natural regeneration is
going on in the catchment area.
The above study in Manipur revealed that
there has been an increase in the water spread in
waterbodies/aquaponds. This is mainly due to
conversion of agriculture and marshy/swampy
land into aquaponds. There is rapid increase in
fi shing activities in the state of Manipur, and
annual fi sh yields from these aquaponds have
also increased.
26.12.3 Example(s) from Coastal
Area(s)
Coastal areas could be regarded as the place
where the waters of the seas meet the land. These
are unique places in our global geography. They
are endowed with a very wide range of coastal
ecosystems like mangroves, coral reefs, lagoons,
sea grass, salt marsh and estuary. The combination of freshwater and salt water in coastal estuaries creates some of the most productive and
richest habitats on earth. The resulting bounty in
fi shes and other marine lives could be of great
value to coastal nations. But these values could
diminish or even be lost if they are not managed
properly. Pollution of coastal waters could greatly
reduce the production of fi sh due to the degradation
of coastal nursery grounds and other valuable
