Response and Adaptability of Mangrove Habitats from the Indian Subcontinent
Mangrove habitats, a great ecological and socioeconomic resource predominately exist in the tropical belt that extends from 30° S to 30° N. The Indian subcontinent harbors ;9700 km
of mangrove area. The major formations occur in the regions of the Indus, Sunderban, and Mahanadi deltas, the Gulf of Kutchchh, the Andaman and Nicobar group of islands, and a part of the west coast and the Jaffana peninsula in the north of Sri Lanka. A wide range of anthropogenic activities have been the major cause of large-scale deterioration and reclamation of mangroves. These activities include urbanization; agricultural, industrial activities; constructions of jetties and ports; dumping of waste, material, and garbage; effluent release; mining; deforestation. The larger scale damage in the recent past is mainly attributed to a lack of, or poor management. Increased anthropogenic activities and resultant temperatures are likely to cause thermal expansion, melting of ice, and rising sea levels. Global emissions of greenhouse gases are likely to raise the world temperature and the sea level at the rate of 0.38�C and 6 mm 10 y
by the year 2100. The potential impact of global warming and sea level rise (SLR) is a great concern for ecosensitive marine habitats. By altering ecobiological processes, the intertidal and supratidal zones may extend further inland, resulting in changes in the existing ecological setup. The limitation of the landward margin would cause vertical rise, resulting in water-logging and ultimately killing the mangroves and dependent biota.
