Current public attention to efforts by the Standing Rock Sioux to protect their water supply by blocking construction of an oil pipeline has drawn attention to Native water rights issues. Anne Strainchamps at Wisconsin Public Radio’s To The Best of Our Knowledge had me on last week to talk about the broader issues.

Greenhouse gases and southwest “megadrought”

Scientists have dubbed decades-long periods of aridity in southwestern North America “megadroughts“. We’ve had them in the past, and research has long pointed toward an increasing risk of them as the climate warms.

Municipal water conservation – lots more room to move

Central to my “decoupling” argument is the premise that, in addition to the water conservation we’ve already seen, we have significant opportunities to conserve yet more. This from  Dave Cogdill (California Building Industry Association and an adviser to the Public Policy Institute of California) puts some numbers to the thing: New homes are quite water efficient, …
