Fresh water availability is crucial for food security as it is required for crop and livestock production. Especially irrigated agriculture needs large quantities of fresh water and uses nearly 70 percent of the global freshwater appropriate for human consumption. Population growth combined with dietary shifts and increasing relevance of non-food crops heavily increase the pressure on fresh water resources. At the same time, climate change strongly affects the spatial and temporal availability of fresh water. To ensure food security and not only yield it is necessary to understand the impact of irrigation on composition (micronutrients) of crops and further food products on food security.
Considering these developments, scientifically based solutions are necessary to ensure water and therewith food security for future generations.
This session combines approaches which aim to scientifically contribute to achieve food security in the water scarce world. Studies presented in this session combine multidisciplinary approaches of climate change impact assessment and farmers’ adaptation strategies, decision support tool development, and the development of alternative water use strategies such as ocean and lake farming or comprehensive sets of site-adapted solutions for improved fresh water management.
