    This reports summarizes and synthesizes activities and achievements of the CGIAR Challenge Program on Water and Food (CPWF) through the end of 2007. The CPWF is an intiative of the CGIAR designed to take on the global challenge of water scarcity and food security.

    Rice, a staple food for over 70% of Asians, is also the single biggest user of water, requiring 2-3 times more input (irrigation plus rain) water per unit of grain produced than crops such as wheat and maize. With growing populations, increased urbanisation and environmental degradation, the supply of fresh water is depleting. Recognising the water constraints to rice yield, the aim of the project entitled ‘Developing a System of Temperate and Tropical Aerobic Rice (STAR) in Asia’ was to develop water-efficient aerobic rice technologies.

    More irrigated land is devoted to rice than to any other crop. A method to save water in irrigated rice cultivation is the intermittent drying of the rice fields, known as alternate wet/dry irrigation (AWDI). This report reviews previous studies in AWDI, with a focus on mosquito vector control, water saving, and rice yields. Examples are provided from a number of countries.

    Over the past several decades, DRP Korea has suffered from extensive land degradation leading to the loss of livelihoods causing increased food insecurity. To restore degraded sloping land, the Ministry of Land and Environmental Protection of DPR of Korea (MoLEP), the Swiss Agency for Development and Cooperation (SDC) and the World Agroforestry Centre (ICRAF), have been promoting the multi-purpose use of trees to transform landscapes and livelihoods using a participatory approach.

    Palestina, Asia, Asia oriental

    In regions where water is in short supply, wastewater treatment offers the possibility for the efficient removal of unwanted pollutants and germs so that the water may be used for irrigation. Water scarcity is an old problem in Palestine because of various geographical settings and political turbulence. The problem is compounded by population growth and development. As a result of the increasing demand for water, using alternative options has become a must to meet water needs.

    The paper demonstrates the application of a new water accounting plus (WA+) framework to produce information on depletion of water resources, storage change, and land and water productivity in the Indus basin. It shows how satellite-derived estimates of land use, rainfall, evaporation (E), transpiration (T ), interception (I ) and biomass production can be used in addition to measured basin outflow, for water accounting with WA+. It is demonstrated how the accounting results can be interpreted to identify existing issues and examine solutions for the future.
