Urban water, urban birds

When I’m in Phoenix, I always try to squeeze out some time to go birding at the Gilbert Water Ranch, a constructed wetland where practical water management has been turned into a lovely urban amenity.

The shrinking of the American lawn

According to this piece by Andrew McGill of CityLab/The Atlantic, the average American yard has shrunk by 26 percent since the 1970s, as homes get larger while lots get smaller: The shrinking lawn is actually an economic compromise.

The removal of two dams on the Elwha River, on Washington’s Olympic Peninsula, has been rightly celebrated as a major achievement – returning a river and its fish to their old channel.

Stuff I wrote elsewhere: The Great Decoupling of the West’s Water

This 2010 paper by Peter Gleick and Meena Palaniappan planted the seed, and as I worked on my book I found examples everywhere – geographies and economic communities that are using less water even as they were growing. I blogged about it, as one does, one thing led to another, and when I finished the book …

Green versus green: removing Snake River dams

One of my University of New Mexico Water Resources Program colleagues frequently points out what they call “green versus green issues” – environmental tradeoffs that are often under-examined because our environmental discourse focuses on one set of values without sufficiently incorporating other values. Today’s inbox missive: removing dams from the Snake River in the U.S. …
