Peter Gleick: California’s next one million acre-feet of water

Peter Gleick:

This is a key time for California water: we are coming off of three years of serious drought and growing political conflict over water allocations. The Legislature passed a comprehensive water bill last November. A major water bond was proposed to fund a wide range of interventions, but has now been tabled for at least two years and could be greatly altered or even scrapped altogether. New reviews from around the state are calling for prompt efforts to use infrastructure, markets, and institutional reform to address the state’s water crisis. All parties agree that the state will need a diverse portfolio of solutions for our diverse and complex water problems.

But the argument that we must do everything at once — conservation, new dams, seawater desalination plants, replumbing the Delta, some of this or that — is disingenuous, and wrong. We must do the most critical and effective things first, from a technical, political, and economic perspective.

And the most effective thing, hands down, is improving water-use efficiency. The Pacific Institute has just released a new analysis that recommends a set of specific actions that can annually save a million acre-feet of water quickly and at a lower economic and ecological cost than developing new supplies. These water savings are split 30/70 between the urban and agricultural sectors.
