I read this just now:
IS THIS the face of future water conflicts? China, India and Saudi Arabia have lately leased vast tracts of land in sub-Saharan Africa at knockdown prices. Their primary aim is to grow food abroad using the water that African countries don't have the infrastructure to exploit. Doing so is cheaper and easier than using water resources back home. New Scientist
Do we really want this to happen in Africa? Mineral resources, rain forests, water . . . What can we do?
