The story of settled agriculture, the growth of cities, and the rise of early empires is, to no small degree, a story of controlling water to make the land more prosperous and habitable. Pillar of Sand examines the history, challenges, and pitfalls of irrigated agriculture ? from ancient Egypt and Mesopotamia to twentiethcentury India and the United States.
