The overall goal of the project is to contribute to achievement of sustainable development of water for poverty alleviation and food security. The purpose of the proposed project is to assess the impact of water and food related policies on water scarcity, food production, food security, environment and livelihoods through the year 2025 at the global, regional, and local scale. This modeling exercise will provide objective and scientifically sound analyses of water-for-food related discussion issues that were raised during and after the World Water Vision meeting in The Hague. The modeling results will be a major contribution to the Dialogue for Water, Food and the Environment that was launched by a consortium of ten international institutes (including IWMI and IFPRI). The project will develop two linked and integrated models: a state-of-the-art research and analytical model to support the Dialogue, and a transparent and user-friendly model that allows interactive scenario testing with national and international policy makers to inform irrigation investment and water policy decisions.
Collaborators and partners: IFPRI and IWMI

ICID - Country Policy Support Studies
PODIUMSim – Model for National Level Water and Food Policy Dialogue Released
As part of the World Water Vision 2025, IWMI developed PODIUM- the Policy Dialogue Model (http://www.iwmi.cgiar.org/tools/podium.htm) in 1999.
PODIUM enables the users to develop national level scenarios of water and food supply and demand on various policy options. Though PODIUM was recognized as a useful tool for generating scenarios, some limitations were also identified. Inability to capture spatial variations, especially in large countries, was a major limitation in PODIUM. The revised version, named PODIUMSim addresses these limitations. PODIUMSim was developed in collaboration with International Commission for Irrigation and Drainage (http://www.icid.org/) under Country Policy Support Studies (CPSP) program (http://www.icid.org/cpsp.html). Under the CPSP program the revised model is being applied at the river-basin level in India and China.
