The goal of the project was to understand the challenges posed to food security by the changing climate and how to overcome these. The project used simulation models to assess food and water demand and climate change impacts on production of staple crops, and identified some adaptive measures, in the three participating countries. Food security in all the three participating is at the risk of being disturbed as a result of global climate change and climatic variability. All study sites showed declining trends in crop yields which could have severe food insecurity concerns. National Planners and Policy makers can use this information to manage agricultural production and food security issues. A total of four workshops and three National Seminars for Policymakers and Planners in Bangladesh, Pakistan and Sri Lanka were organized to disseminate the research results. The project outcomes were highly appreciated by the participants who emphasized that economic valuation of the impacts also needs to be done.
