Realising the significance of using micro irrigation system as a demand management strategy, an attempt has been made in this chapter to examine the social benefit-cost analysis of drip irrigation. As found in many earlier studies, the drip irrigation resulted in significant increase in yield over the flood method of irrigation. The analysis of economics of crop cultivation in drip and control villages revealed that the drip method of irrigation has significant impact on resource use, cost of cultivation, yield of crops and farm profitability. The social benefit-cost analysis revealed that the social benefits exceed the social costs in the water and labour scarce regions. Thus, one can conclude that the drip irrigation is a viable and more beneficial in regions where there is more water scarcity. The social benefit-cost ratio (SBCR) in over-exploite...

The value of groundwater as a new source of supply is well known. However, its additional buffering or stabilization value is less appreciated and even less analysed. ...

The impacts of major watershed development programmes have been outlined in terms of biophysical impacts, environmental impacts, socio-economic impacts and overall economic impacts. It is pointed out that the watershed development activities have made significant positive impacts on various biophysical aspects such as soil and water conservation, soil fertility, soil and water erosion in cropped area, changes in cropping pattern, cropping intensity, production and productivity of crops. Watershed development activities have shown significant positive impacts on water table, perenniality of water in wells, water availability for cattle and other domestic uses, etc. The overall economic impacts have been evaluated in terms of NPV, IRR and BCR. The peoples' participation in watershed development activities has been found satisfactory but the optimal level is yet to be achieved....

Conventional methods to value them using financial measures attempt to quantify the impacts of watershed development in an isolated manner. In order to evaluate the impacts of watershed programmes in a holistic manner, the Economic Surplus (ES) approach has been applied using the data from a cluster of 10 watersheds in the Coimbatore district of Tamil Nadu. The distributional effects of watershed programmes are also captured through the ES method. Hence, possibilities of using this methodology in the future watershed evaluation programmes could be examined. The study has suggested that people's participation, involvement of Panchayati Raj Institutions, local user groups and NGOs alongside institutional support from different levels, viz. central and state government, and district and block levels should be ensured to make the programme more participatory...

Climate change and agricultural water management in Developing Countries, 2016

There is an increasing concern among farmers, researchers and policy makers about the potential impacts of climate change on food security and livelihoods. Researchers are using several climate change models to make an assessment of the impacts and identify adaptation strategies. The present chapter reviews the current state of understanding of the climate change impacts on irrigation water in South Asia and specifically on the crop yield and relevant adaptation measures in three major river basins (Godavari, Krishna and Cauvery) in India. Optimization model was used to evaluate the different adaptation practices and their potential to maximize rice production and income, and minimize water use for the mid- and end-century climate-change scenarios. Adaptation practices such as systems of rice intensification, machine transplantation, alternate wetting and drying (AWD) and direct seeding could r...

Can the System of Rice Intensification be the answer to meet the country's future rice demand... more Can the System of Rice Intensification be the answer to meet the country's future rice demand? A macro-level study covering 13 major rice-growing states indicates that fields with SRI have a higher average yield compared to non-SRI fields. Out of the four core SRI components typically recommended, 41% adopted one component, 39% adopted two to three components, and only 20% adopted all the components. Full adopters recorded the highest yield increase (31%), but all adopters had yields higher than those that used conventional practices. They also had higher gross margins and lower production costs compared to non-SRI fields. Though the rice yield of the country can significantly increase under SRI and modified SRI practices, there are major constraints that have to be tackled before this can be achieved
