摘要
Large dams, though necessary for national growth, adversely affect the life-support strategy of a large number of people living in the submergence zone and the hinterland of the reservoir. With the help of GIS-based techniques and land-use/land-cover map prepared with the help of satellite remote sensing tools, it is estimated that the Tehri reservoir in the upper catchment of Ganga river would directly affect 2687 ha of agricultural land and another 3347 ha around the reservoir rim would be rendered unfit for cultivation.
