At dinner the other night, one of the people at the table commented about the risk we face when the Ogallala Aquifer, beneath the great plains, runs out, which he’d heard would happen in 20 years. Without taking action now to begin regrowing the native grasses needed to hold the plains in place, he’d heard, …

Visiting a farm recently, I was reminded that business people for whom water is an input think about water conservation differently than city folk like me. For a given amount of water available, the farmer wants to grow and sell as much food as possible. So it should not be surprising to see water conservation …

Hannah Holm of the Water Center at Colorado Mesa University argues that agricultural water conservation doesn’t really save water: When water is diverted from a stream and put onto the land, part of that water is taken up by plants, part of it evaporates, and part of it makes its way back to the stream. With …
Given my profession, I’m incentivized to freak out about drought. If I thought it wasn’t a big deal, I’d have to find something else to write about. But in darker moments, I wonder if I’m overdoing the freakout. Chris Austin’s writeup of Ellen Hanak’s comments at this week’s California water bond hearing raise the question …
The Jevons Paradox would suggest that our new solar panels would give me an easy comfort about using more electricity. And yet, ever since we gathered two weeks ago with the installers and the electric company guy in the ritual of turning them on and watching the meter run backward, I have been obsessed with …

Nearly every time I give a talk on water (which seems to happen frequently lately – wonder if I’ll be less popular as a speaker once the drought ends) I get asked about desalination. It is, as Bettina Boxall noted in a recent LA Times story, the stuff of dreamers: “an inexhaustible, drought-proof reservoir in …
The “broken windows fallacy” is the economic argument that spending money on X is of intrinsic value because of the jobs created, regardless of the value of the thing being done. The reference to broken windows is the argument’s reductio ad absurdum – hire one person to break a bunch of windows, and a second …
I consider the business model that supports my journalism a great privilege. But I understand that a big part of the benefit offered by news production is a classic case of what economists call a “public good“. That is to say, civil society as a whole benefits, even if you don’t have the time to …
At the peak of the housing bubble in January 2006, when the annual pace of new home construction hit a blistering 2.29 million units, an estimated 14 percent of laborers in the construction sector were undocumented immigrants, including 20 percent of carpet, floor and tile installers, 28 percent of drywallers, and 36 percent of insulation …
Just the blog equivalent of thinking out loud here. It’s not that this data was surprising to me, so much as that I wasn’t sure what to expect. Four cities in the western United States with some similar characteristics – arid climate, water supply challenges, growing populations. Each of the four is the dominant population …
