A private company, Cadiz Inc. (Cadiz), has revived plans to mine groundwater underlying land in the delicate Eastern Mojave Desert. This project revives fundamental questions about how we manage our precious water resources, and in particular, whether in the 21st century it is appropriate, or even necessary, to use renewable water resources in a nonrenewable and unsustainable way, for short-term profit.

Geologic time scales are long – too long for the human mind to really comprehend. Over millions, and tens of millions, and hundreds of millions of years, the Earth has changed from something unrecognizable to the planet we see on maps, plastic globes, and photos from space.

Not all zombies are fictional, and some are potentially really dangerous – at least to our pocketbooks and environment. These include zombie water projects: large, costly water projects that are proposed, killed for one reason or another, and are brought back to life, even if the project itself is socially, politically, economically, and environmentally unjustified.

When I go to water meetings, there are serious scientific discussions about climate impacts on water systems, international conflicts over water, water quality and contamination threats, new technologies and strategies for providing basic water and sanitation for the world’s poor, and much more. But in the hallways between meetings and sessions, the real arguments are about the conflicts between public and private control and management of water.

The world faces a wide range of serious, complex, and long-term water challenges, from shortages to contamination to local and regional disputes over water to long-term climate changes.
