| In recent years there has been increasing regulation of agricultural water use in order to reduce transboundary and environmental water conflicts. Effective policy analysis needs to have tools to estimate correctly the value of irrigation water. Irrigating land increases crop yields and this higher profitability should be capitalized into the sales price of the land. For irrigation that depends on surface water rights, studies have found this to be the case (Xu et al. 1993, Faux and Perry 1999). However, studies that have analyzed the value of groundwater in irrigation have found mixed results. Hartman and Taylor (1989) and Sunderland, Libbin and Torell (1987) find that groundwater irrigation has no significant effect on land prices; Torrell et al. (1990)... |

| Farming communities in water-scarce regions increasingly practice the use of urban wastewater in agriculture. Untreated urban wastewater is generally considered unacceptable for direct use because of potential health risks. However, in many parts of the world, poor farmers in peri-urban areas use untreated wastewater. This situation is considered likely to continue even in the foreseeable future due to the high investment cost associated with the installation of treatment facilities. |

| In this study, the cost of groundwater extraction, impact of groundwater depletion on farm income, wateruse efficiency, technical efficiency in crop production and costs of groundwater depletion among different categories of farmers have been reported. The study has been conducted in the Chamarajanagar district of the Karnataka state, where groundwater is the major source of irrigation. Data have been collected from over-exploited, semi-critical and safe villages. The study has shown a wide difference between large and small farms in their access to groundwater resource in terms of cost. The functional analysis has revealed that farm income is lower in over-exploited and semi-critical villages compared to safe villages. The mean technical efficiency in... |

| Of the four major ways of storing water -in the soil profile, in underground aquifers, in small reservoirs, and in large reservoirs behind dams-the first is possible only for relatively short periods of time. In this paper, the authors concentrate on the three kinds of long-term technologies, and compare the hydrological, operational, economic and environmental aspects of each. |

| With a rapidly expanding economy many changes are taking place in India today. The business-as-usual (BAU) scenario, which assumes the continuation of current trends of key water demand drivers, will meet the future food demand. However, it leads to a severe regional water crisis by 2050, where many river basins will reach closure, will be physically water-scarce and will have regions with severely overexploited groundwater resources. While the alternative scenarios of water demand show both optimistic and pessimistic water futures, the scenario with additional productivity growth is the most optimistic, with significant scope for reducing future water demand. |
