Given the impacts of global change on water and food security and the need for increasing agricultural intensification, this research theme examines the tradeoffs for water and food security. This research includes global modeling of water, food, and energy; projections of current and future demand for water for food production; integrated hydro-economic modeling, models linked across scales; and off-site and on-site modeling of water management and ecosystem health. Key sub-topics include:

Economic impact, investment, and growth

• Water and growth
• Economic impacts of water scarcity
• Investments in water (public/private)

Water and climate change linkages

• Climate change impacts on water supply
• Adaptation to climate change

Water quality impacts of agricultural intensification
