"Eliminating water shortages depends on a global attempt to raise water productivity similar to the effort launched a half-century ago to raise land productivity, an initiative that has nearly tripled the world grain yield per hectare." –Lester R. Brown, World Facing Huge New Challenge on Food Front in Plan B 3.0: Mobilizing to Save Civilization
Joel Makower of GreenBiz.com spoke with Lester recently about the challenges and opportunities in a world with a growing demand for food, a rising population and climate change. Lester said, "What's happening is that we're seeing a tightening of food supplies. We're going to see much higher food prices in the future. We've actually seen world grain prices double since early 2007 and that increase is going to continue in the future. And not only is that rise in prices likely to continue, it may well accelerate because we're pressing against the limits in so many parts of the world." Check out the full interview here.
