Abstract

Is there enough water to feed a growing population over the next 50 years, or will we run out of it? Agriculture accounts for 70% of global freshwater withdrawal. In 2050 food demand is predicted to increase by 70%, while the impacts of climate change are set to add further stress to water availability, leading water supply to become less reliable in several areas. Current water use systems and future perspectives require solutions to better use water and guarantee food security under changing climate conditions.
