Write about causes and distribution of coastal erosion in India.
Answers
Between 1990 and 2016, 33 per cent of India’s coastline underwent erosion and in the same duration, about 29 per cent of the coastline expanded, shows a recent technical report by the National Centre for Coastal Research (NCCR) under the Ministry of Earth Sciences.
In the last 26 years, India’s coastline has undergone major changes, said the report which was prepared to determine long-term changes in the shoreline. Using observations from five satellites, the survey covered about 6,632 km of the 7,517 km long coast line, across nine coastal states and two union territories, excluding the Andaman and Nicobar Islands.
Shoreline observations were recorded for 1990, 2000, 2006, 2008, 2012, 2013, 2014, 2015 and 2016. The survey showed that while 2,533 km, or 38 per cent of the country’s shoreline, remained stable; 2,156 km had eroded and the remaining 1,941 km expanded over 26 years.
