Coastal Landscape of Maharashtra: An Overview
摘要
The resource-rich coastal zone experiences intensive and competing use and is also under stress across the world. There are national and international initiatives to devise appropriate management plan for the coastal zone. Decentralised, site-specific analysis provides important gateway in this direction. This chapter presents the case of Maharashtra state, one of the progressive states in India. Maharashtra coast, popularly known as Konkan coast, stretches over a length of 720 km along the Arabian Sea. It is a high energy, rocky coast with headlands-bay complexes found all along. The tidal range is high with decreasing trend from north to south. The major landform features evolved along the coast include beaches, creeks and estuaries, mangroves, headlands, shore platforms, sea cliffs, caves and islands. The beach is not continuous and is marked in 82 patches. There are 44 islands formed under different environmental set up. The coastal configuration was conducive for development of ports and harbours. Mumbai city, the financial and commercial capital of India, originally evolved as a port city. Around 65% of coastline of Maharashtra is stable, while 24% of coastline experience erosion of various intensity. High erosion segments are mostly noted in Palghar, Thane, Ratnagiri and Raigad districts. The coastal area, intensely used for various purposes, is undergoing changes, driven both by natural forces and human actions. Loss of ecological habitat, occurrence of coastal hazards and increasing vulnerability are major causes of concern. Multi-factor coastal vulnerability study brought out that the north Maharashtra coast from Mumbai to Gujarat border is highly vulnerable, whereas the southern part is less vulnerable. Integrated approach is necessary to address coastal zone management problems.
