Heart of dryness : how the last Bushmen can help us endure the coming age of permanent drought

This nonfiction narrative set in the Kalahari dramatizes the timeless struggle over water, the fulcrum of political power. Facing drought, scarcity and climate change the besieged indigenous Bushmen use voluntary survival strategies while Botswana's government enforces regulatory rule. Their rivalry foreshadows our world, where two in three thirsty humans will soon endure shortages, resource conflict, a $900 billion market, and a global fight for water as a human right.
