I recently read Heart of Dryness (http://www.heartofdryness.com/) by James G. Workman. In an age of permanent drought, this book explores what we might learn from the Kalahari Bushmen about how to manage water resources. The book is well-worth reading, both intellectually and emotionally rewarding.

Circle of Blue is doing a 7-part series of excerpts here: http://www.circleofblue.org/waternews/2010/world/heart-of-dryness-revers...
