Estimates on lost reservoir capacity in India provide an alarming picture. There are several instances of soil erosion and sedimentation with run-off water. The cost of sediment removal from a large reservoir may be high, in addition to cost of dam construction. The present article estimates the loss to economy by siltation of Sardar Sarovar reservoir through loss of electricity generation and agricultural productivity. The article also suggests adoption of intensive soil and moisture conservation measures on scientific lines from protection viewpoint.Keywords

Watershed management is considered as a way for sustainable rural development and thus impact evaluation is a must. The common approach of postclassification comparison of pre- and post-implementation satellite imageries for watershed impact evaluation suffers from serious limitations, mainly ignoring the changes which are not due to watershed interventions. To minimize such biases, control area approach is proposed and relative change in watershed compared to control area is attributed to watershed management. The studied four clusters of watershed in Vidarbha region, Maharashtra show that the effect of the watershed could stand out irrespective of pre- and post-implementation conditions of satellite imageries.Keywords
