Coastal zone is highly dynamic in nature and undergoes rapid change. It plays an important role in the livelihood of 55 million people along Indian coast. The critical issue faced by the coastline includes coastal erosion, Sea Level Rise (SLR), urbanization, industrialization, and resource management. 23% of Indian coastline is facing coastal erosion and this problem is relatively severe in Dakshina Kannada, making it a critical stretch. As per NOAA report prediction, global SLR is of the order of 0.5–2 m over the next century which ultimately cause extensive loss of low lying coastal areas. The present study is carried out with a view to identify the coastal vulnerability sites along 40 km stretch of Mangalore coast, starting from Talapady in South to Mulky in North. Both conventional and remotely sensed data, coupled with field data were employed to identify critical erosion zones, over a period of 16 years. ERDAS Imagine (2014) software was used to analyze the satellite data to prepare Land Use/Land Cover map. This can be employed in identifying area of land submergence, in case of coastal inundation and to develop ICZMP for Mangalore Coast. |
