Why is Coastal Erosion The imminent danger?

What is Coastal erosion? New Delhi, July 19th: Coastal erosion is the displacement or loss of land caused due to rise in sea level, resulting in strong waves and coastal flooding. There are anthropogenic activities or natural causes that hasten the erosion of the coast. What are the Natural causes of coastal erosion? Natural causes of coastal erosion are hydraulic actions, attrition, abrasion, corrosion, and solution (acidic elements of the seawater dissolving rocks containing limestone or chalk). This affects the communities that live along the coast and depend on it for their livelihood. At the same time, the area’s biodiversity, including plant and animal lives, is seriously endangered. How many coastal districts are there in India? The Indian mainland has 9 coastal states and 2 Union Territories, having 66 coastal districts (2018). A 2018 report published by National Centre for Coastal Research (NCCR) says around 99 sq.km of land along the West Bengal coast alone was lost during 1990-2016. More than 40% of erosion is noticed in four states: West Bengal (63%); Pondicherry (57%); Kerala (45%) and Tamil Nadu (41%). The sea levels swelled by 40 cm in the past century. It is projected to rise by another 60 cm by the next century. As per the IPCC report, a rise of 1 mm per year can inundate about 0.5 m per year. In response to a question, Dr Jitendra Singh, Union Minister of State (Independent Charge) of the Ministry of Earth Sciences, Minister of State (Independent Charge) of Science & Technology, Minister of State in the Prime Minister’s Office, Minister of State in the Ministry of Personnel, Public Grievance, informed the Lok Sabha on 6 April 2022 that about 34% of India’s 6,907.18-km long coastline was under varying degrees of erosion. “As per the 6thAssessment Report (AR6) of the Intergovernmental Panel on Climate Change (IPCC), relative to 1995-2014, the global mean sea level is expected to rise by 2100 is 0.28-0.55 m under the very low greenhouse emission scenario (SSP1-1.9), 0.44-0.76 m under the intermediate emission scenario (SSP2-4.5), and 0.98-1.88 under the very high emission scenario (SSP5-8.5),” the Minister…
