A REVIEW ON STUDIES PERFORMED TO ASSESS THE IMPACT OF CLIMATE CHANGE AND ANTHROPOGENIC ACTIVITIES

Climate change is wreaking havoc on many types of ecosystems and biodiversity around the globe. Changes in temperature and rainfall patterns, the frequency and amplitude of cyclones, forest fires, disease outbreaks, and other climate change effects were all felt. The severity of these consequences is predicted to increase significantly in the future, but relatively few studies have been conducted in India to evaluate ecosystem vulnerability due to climate change on a regional scale. As a result, the goal of this study is to determine the impact of climate change on ecosystems along the Puducherry region's shoreline in the Union Territory of Puducherry. This page summarises a number of research that look at the effects of climate change on coastal ecosystems, such as changes in cyclone frequency and impact, sea-level rise, and the amount of urbanisation near coastal regions. Studies on mangroves, coastal sand dunes, and turtle nesting along Puducherry's coast were reviewed in particular. Climate change and anthropogenic influences have reduced the spatial area of mangrove vegetation in the last decade, according to the study. Tourism, fishing, construction, Casuarina plantations, soil erosion, and sea-level rise have all been identified as serious threats to the nesting areas of three critically endangered marine turtle species: Olive Ridley (Lepidochelys olivacea), Leatherback (Dermochelys coriacea), and Hawksbill (Eretmochelys imbricata).
