“…Especially where water is scarce and poverty widespread, water infrastructure can improve the livelihood of people. Large dams can facilitate access to water in water-scarce regions by improved ground water levels and increased fl ows in downstream areas during water scarce periods; thereby increasing food security (Shah and Kumar 2008 ). In addition to irrigation, water supply and fl ood control, electricity generation by hydropower has been a major driver for many large-scale water infrastructure projects (Biswas and Tortajada 2001 ).…”

“…Shah and Kumar ( 2008 ) analyse large dams in 145 countries and fi nd that the main arguments for large dams are food and drinking water security, hydropower generation, and fl ood control. The criticism against large dams generally focuses on environmental, fi nancial, economic, and human rights issues (ibid.).…”

Major water infrastructure projects like dams can provide substantial benefi ts such as food and drinking water security, hydropower generation, and fl ood control. But these benefi ts may come at a (too) high cost of large scale ecological alterations or adverse social impacts such as involuntary resettlements. If these costs are neglected, an investment decision will hardly be effi cient. In this chapter, we will stress the necessity to make these "neglected values" visible and demonstrate how this can be achieved through economic valuation.

“…For instance, water has been allocated to Concentrated Solar Power (CSP) plants in Rajasthan from the agricultural water apportionments in the Indira Gandhi Canal (Bhushan et al 2015a). Such unplanned reallocations can be observed across the country for satisfying the rising demands for water in the power, industry and domestic sectors (Joy et al 2008;Shah and Kumar 2008). The increasing water scarcity and the piecemeal and sectoral approach to water legislation have exacerbated inter-sectoral allocation issues and increased conflicts between different users (Cullet et al 2015).…”

Climate change is a major concern in the twentyfirst century and its assessments are associated with multiple uncertainties, exacerbated and confounded in the regions where human interventions are prevalent. The present study explores the challenges for climate change impact assessment on the water resources of India, one of the world's largest human-modified systems. The extensive human interventions in the Energy-Land-Water-Climate (ELWC) nexus significantly impact the water resources of the country. The direct human interventions in the landscape may surpass/amplify/mask the impacts of climate change and in the process also affect climate change itself. Uncertainties in climate and resource assessments add to the challenge. Formulating coherent resource and climate change policies in India would therefore require an integrated approach that would assess the multiple interlinkages in the ELWC nexus and distinguish the impacts of global climate change from that of regional human interventions. Concerted research efforts are also needed to incorporate the prominent linkages in the ELWC nexus in climate/earth system modelling.

“…We have to manage decreasing water resources & increasing demand along with maintaining the ecological sustainability (Saito et al, 2012;Jain et al, 2008). Assessment of the dependable inflow in existing dams is the first and primary step in the field of water management (Garg, 1984;Shah & Kumar, 2008). To test the actual inflow whether it is dependable or not, a null hypothesis has been generated: "There is no change in the water inflow pattern in the dams of Rajasthan state, i.e.…”

Rajasthan is a semi arid state with the highest of the geographical area (343,000.00 square km) of the Indian subcontinent. Annual rainfall variation is very high over the state ranging from 100 mm to 1000 mm from west to south/east. Matter of water resources planning is of prime importance for the state. There are 237 blocks, out of which 200 blocks are declared as dark zone due to over exploitation of ground water. In these circumstances, it becomes necessary to plan the storage and uses of surface as well as subsurface water (conjunctive use) with maintaining the ecological sustainability. Surface water reservoirs are becoming dry year after year. It was observed from the annual storage data of the dams that water inflow is declining year after year due to various reasons like changes in land use and land pattern, change in hydro geological conditions, changes in environmental factors e.g. temporal and spatial distribution of rainfall, indiscriminate infrastructural development. Due to less water inflow in the dams and increase in the number of dark zone blocks, state is facing the water stress problem. With the increasing population, it will become more severe with the passage of time. Therefore, an effort is being made through this research to test the hypothesis whether there is an appreciable change in water inflow in the dams of Rajasthan state. A total of 115 nos of major & medium dams in the state have been selected by cluster sampling to test the hypothesis. Chi Square test has been conducted for testing the hypothesis and found that there is declining trend of water inflow in the dams and dependabilities of the river basins have been reduced.
