The major activities that are responsible for coastal pollution in India are discharge and
disposal of untreated domestic and industrial wastes, discharges of coolant waters, harbour
activities such as dredging, cargo handling, dumping of ship wastes, spilling of cargoes
such as chemicals and metal ores, oil transport, fishing activities such as mechanized fishing
vessel movement, draining of waste oil, painting of fishing vessels, inflow of fresh water
into this part of Sundarbans as a result of the construction of the Farrakka Barrage in 1971,
designed to divert fr,
Calcutta. Inflow is now confined only during the monsoon period. In the state ofTamilnadu,
between the years 1986 and 1993, 0.36 km" of mangroves in Pichavaram was lost and over
a period of 20 years 2825 km2, were lost (Ramachandran et al. 1995). Mangrove destruction in the Andaman and Nicobar islands is described by Singh et al. (1986) and Balga and
Menon (1989). About 10 000 ha have reportedly been cut since 1960, mainly for fuel. The
reports {)f Ministry of Environment and Forests, Government of India (1987) have shown
