***** (***** | *****)Increasing water scarcity is posing a major challenge for meeting the continuously growing demand for water from all sectors. In many developing countries, in particular, this crisis is likely to be further exacerbated by the negative impacts of climate change on overall water availability. Potentials for mobilizing additional water resources are often limited and extremely costly to realize. Consequently, irrigated agriculture as the largest water user will face growing competition for scarce water resources from other sectors with higher use efficiency and value added. For meeting the ever increasing demand for food, fiber and other products, irrigated areas wherever feasible have to be extended, and existing irrigation schemes often require rehabilitation or modernization to ensure a more rational and efficient water use. However, related additional investments are substantial and accordingly require adequate financial and economic justification.
