Track 5: Land-use, water and food - at the heart of sustainable economies and cultures

Our current efforts to provide food and water to a world population of 6.5 billion stress the ecosystems that support us.

This competition between global land-use priorities is now set to intensify with the shifting emphasis towards biofuels. What is a sustainable diet? Can one Earth supply this diet?
