(a) Eutrophication, siltation, pollution, overexploitation, encroachment, etc., are some of
the major problems with the wetlands of
Manipur.
29.2.5.4 In Tripura
Potentials
1. Wetlands assume special signifi cance in
Tripura. Four hundred eleven wetlands covering an area of c 6,327.70 ha (pre-monsoon) have been identifi ed. Each of these
wetlands is >2.25 ha in area. There are, further, 3,407 number of wetlands which
are <2.25 ha in area. The vast area covered
by the wetlands is itself a sign of its rich
potential.
2. Besides providing with fi shes for nutrition,
habitat for biota, etc., the wetlands also provide
livelihood support to many people. They also
help in navigation and fl ood management.
