"India has a 7516.6 km coastline spread over nine coastal states with a 2.02 million sq km exclusive economic zone (EEZ). The peninsular region of India has the Arabian Sea on the west, the Bay of Bengal in the east and the Indian Ocean in the south. The coastal zone is a unique environment where land, ocean and atmosphere interact and produce a highly dynamic and important ecosystem. Estuaries, mangroves, coral reefs, sea grassÂ beds, mud flats and sand beaches are the diverse habitats that comprise the coastal environment and provide valuable benefits to human and marine lives. Eric Bird points out, in his book
Coastal Geomorphology: An Introduction, that the total coastline of the world is 3,56,000 km, with coastal zones comprising around 10 per cent of the earthâ€™s surface. The population density in the worldâ€™s coastal zones is much higher than that in non-coastal areas because of the economic benefits and livelihood opportunities that the coastal ecosystem bestows to the people. Coastal habitats, especially mud flats, mangroves, coral reefs, sea grasses and salt marshes are highly productive and serve important ecological functions, besides protecting populations against coastal erosion. However, the w
A coastal zone is one of the most fragile ecosystems on earth. Managing coastal resources sustainably calls for up-to-date knowledge, cutting edge planning and trained human resources. Satellite remote sensing provides synoptic and unbiased content in a multi-temporal domain that can help planners put suitable management policies in place.
