Unsettled questions about Native American water rights in the Colorado River Basin

More than a dozen Native American communities in the Colorado River Basin have yet to have their legal entitlements to a share of the river’s water quantified, according to a new report from the Colorado River Research Group. With the river’s water already over-appropriated (meaning users, largely non-Indian, have built farms and cities that have …

New outlook shifts odds slightly toward dry 2016-17 across Colorado River Basin

At the risk of driving faster than is prudent on a twisty mountain road at night, the new 2016-17 climate outlook released yesterday does not look particularly encouraging for the Colorado River Basin: That’s December 2016 – February 2017. Browns mean odds are shifted toward dry. A reminder that the maps can be a little …

Have we stabilized the Colorado River’s water supplies?

It’s a bait and switch. The answer is “no”. (It always is when it ends with a question mark. See Betteridge’s Law of Headlines.) But as I report in my water newsletter, there are some encouraging signs that we’re moving in the right direction. You can subscribe to the newsletter, which is supposed to come …

I’m not sure I would be as sanguine as this Coachella pepper packer about the long term availability of water: The process of producing peppers is both simple and complicated.  “Workers, water, weather–those are our three big headaches,” Aiton says. Aiton says while water is a concern in the state, it’s not as critical in …

the role of science and evidence in decision-making processes

I’m working on a couple of projects right now in which I’m trying to help policymakers effectively communicate complex science (involving drought, climate change, and water availability, but that goes without saying, right?) in political and policy processes. Paul Cairney suggests the constraints: In debate, evidence is mentioned a lot, but only to praise the …

Nestlé, Phoenix water, and the bicycle shed problem

Toxic materials regulatory reform

I got an education this year in the nuances of global toxic materials regulatory regimes when I served on UNM graduate student Rachel Moore’s masters committee with Caroline Scruggs, a professor here at the university who’s worked for years in this area. (The paper on their work is here.) Caroline showed up in the Albuquerque …
