Abstract

The present study is aimed at assessing the impact of watershed development on the energy efficiency in groundnut cultivation. Overall technical, pure technical and scale efficiency increased by 11, 3 and 12% over the pre-watershed scores due to watershed development. Estimated potential for saving input energy was 3608, 3223 and 2907 MJ ha^-1 for marginal, small and large farmers respectively, in groundnut production while maintaining status quo for energy output. Farm size, age of farmer, number of livestock owned and implementation of watershed activities were identified as key determinants for higher overall energy efficiency.

Abstract

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.

Abstract

Pulses play a major role in providing overall prosperity to the small and marginal farmers through nutritional security by meeting their dietary protein requirements and improving production base through conservation of natural resources. Inclusion of pulses in the cropping system as a crop rotation improves soil fertility and crop productivity of cereals and oil seeds. Chickpea is one of the important pulses cultivated in Vertisols during winter season. We examined chickpea cultivars for energy use efficiency, economics, physiological efficiency and water use efficiency (WUE) under different rainfall situations for their sustainable yield and overall profit, in Vertisols of semi-arid tropics of South India. Results revealed that low input energy and high grain and stover yields of cultivars result in higher total output energy and net benefit energy. Higher dry matter efficiency of 0.702 was observed with medium-duration cultivar, whereas WUE was higher in short-duration cultivar followed by medium-duration cultivar. We conclude that medium- duration cultivar and short-duration cultivar are more suitable for the SAT region in terms of greater energy benefits, higher income per unit area, physiological efficiency and water use efficiency. Thus short-duration cultivar could be cultivated during normal to above normal rainfall years and during normal to drought years in winter season on residual soil moisture in Vertisols medium-duration cultivar for higher energy efficiency and economics.

Abstract

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.

Abstract

Soil degradation induced by erosion represents a major threat to food production and ecosystem service globally, and in India more than 80 Mha have been impacted. In the light of the serious threat, there is a pressing need for a systematic nationwide assessment of land degradation due to erosion. We discuss the potential for using caesium-137 and lead-210 tracers to address this need and the next steps to realizing nationwide implementation.
