Management of scarce resources

A continued increase in production of healthy food depends crucially on the availability of inputs that are becoming increasingly scarce – land, water, and also essential micronutrients. Management of such inputs is critical for food and nutrition security, and raises important research questions. Land and water management present difficult challenges at multiple scales: local, regional and often international (as with multiple countries along a common river basin and through land acquisition by foreign states). Appropriate technologies and management techniques must be identified to enhance sustainable water use. Important questions pertaining to land management are related to concerns about ownership of land and competing uses of land besides agricultural production, such as land-based mitigation of climate change and biodiversity conservation.
