Abstract
Mangroves are one of the most threatened ecosystems worldwide located within the intertidal zones of tropics and subtropics. They provide both ecologic and economic benefits to coastal communities. They safeguard community lives and properties in coastal areas during storm surges, hurricanes, cyclones and tsunamis. Global estimate shows decline in mangrove vegetal covers to ~150,000 sq. km. Degradation of mangrove ecosystems in India are mainly due to continuous increase in anthropogenic activities such as conversion of mangrove wetlands for aquaculture and destruction of mangrove forest for timber. In the coastal areas inhabitants are at risks of losing their livelihood and ecological communities are in the verge of extinction. The effective conservation and management of mangrove habitats should be considered in association with local community participation and application of remote sensing technique and Geographic Information System (GIS)-based comprehensive database approach. We reviewed threats and vulnerabilities to mangrove habitats around the world with a special emphasis in east coast of India. We also reviewed current mangrove management practices. We discussed the importance of acquisition/assessment of remote sensing data for GIS-based effective mangrove management approach in remote Indian coasts. A combination of remote sensing and GIS-based approach will have significant ecologic and economic benefits by gaining real-time data from inaccessible areas. This strategy has valuable implications to other remote/threatened mangrove wetlands worldwide.
