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

A study was carried out to determine the effect of cli-mate change on design rainfall and its effect on design and costing of soil and water conservation structures in watersheds. For this study, the micro watershed located at Central Soil and Water Conservation Research and Training Institute, Research Centre, Research farm, Vasad was selected and rainfall data from 1957 to 2012 was used. The analysis showed that as a result of climate change, there is significant in-crease in number of extremely heavy rainfall days as well as rainfall amount. The design rainfall of various soil and water conservation structures has increased by 11%, 30% and 38% for design of staggered con-tour trenches, contour bunds and check dams respec-tively. The cost of construction of staggered contour trenches, contour bunds and check dams in water-sheds has increased by 26%, 28% and 12% respec-tively. This study reveals that, there is a need to account for design and costing of soil and water con-servation structures in the light of the climate change and a relook into the watershed programmes of the central Gujarat region of India.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

Ravine agro-ecosystems are characterized by degraded gullied lands formed over the years due to several natural and anthropogenic factors, surrounded by the adjacent table lands cultivated for the production of food and fibre for humans and livestock. These potential lands not only support the livelihood of marginal and smallholder farmers, but are host to various plants and grass vegetation providing a cushion to the local environment. A two-way relationship exists between the human settlements and ecosystem services in these agro-ecosystems. While the ravines support plants, grasses and human settlements in these agro-ecosystems, the same biophysical pressures over time degrade the ecosystem leading to ecosystem services loss, if not managed sustainably. The present pilot study conducted in the Mahi ravines, Gujarat, India, has examined these issues from the local socio-ecology perspectives and suggests management options for participatory management.Keywords
