Description Indian remote sensing satellite (IRS) data have been used to find out the Environmental Sensitivity Index (ESI) for the Goa coast which is situated in the west coast of India. It is one of the most sensitive environments in terms of its rich biodiversity and also due to its coastal geomorphologic features. It comprises of mangroves, creeks, Sandy as well as rocky beaches and cliffs. The shoreline is crenulated and segmented, with alternating headlands, cliffs, estuaries, bays, beaches, creeks and spits (Wagle. B.G, 1993). Marine and fluvial features are pre-dominant in this coast. Goa has been identified as one of the major tourist destinations of the world because of its beautiful beaches and associated recreational activities (Vethamony. et al 2007). The economy of Goa depends on tourism and any damage to its environment will badly affect its economy. The aim of the study is to map and rank coastal areas of Goa on the basis of their sensitivity to oil spill using remote sensing and field data. Physical, geomorphic and biological environmental attributes have been used for the study area and respective sensitivity index for oil spills have been derived. These attributes have been used for classifying as well as to rank the sensitivity for oil spills. By using Geomorphology, Land use/ Land cover, Slope, Digital Elevation Model (DEM), part of the Goa coast have been classified and ESI maps are prepared. This map is very important and may be used for spill response contingency planning. The paper uses GIS and remote sensing techniques to achieve the task. The paper suggests the need for having a pre-validated ESI maps in response to action and contingency planning for oil spills in India. This study is of first kind in this region to have an integrated approach using remote sensing and GIS.
