Anthropogenic Interventions in the Coastal Environment – A Serious Threat to Insular Ecosystem in Kadmat Island, Lakshadweep, Southwest Coast of India.

Abstract

The growing crisis in the coastal environment is the presence of pollutants and other anthropogenic activities which ultimately results in deterioration of coastal biodiversity and ecosystem. Present study reports based on the research conducted during November 2019 provide the initial findings regarding the threats faced by the insular ecosystem of Kadmat Island. Transect line with equal intervals and quadrate method were used for the survey of marine debris. Field observations and photographs were taken to record the impact of coastal modifications by unscientific constructions. Sandy beaches are the highly vulnerable marine ecosystem and a number of persistent drivers are negatively impacting and undermining their ability to provide these services. Marine debris contributed mainly by plastic is considered as one of the principle reason for concern in the coastal environment. The uncontrolled developmental activities and unscientific coastal protection measures are another leading cause deteriorating the health of the beaches. This study forms a baseline data for efficient management of coastal environments based on field survey at Kadmat Island of Laskhadweep, southwest coast of India.
