A note on alfalfa export data

There’s a letter to the editor in the latest High Country News (it’s in the paper edition, can’t link yet) that repeats a California water myth that’s just flat wrong – the California Supergiant Alfalfa Water Use Export Myth.

Equity versus efficiency

John Whitehead: Economists are often bad at considering the distributional impacts of policies: To the point that we often ignore issues of equity in favor of the more objective measure of efficiency.  If two policies were to result in the same net benefits to society, but different distribution of those benefits within society, the efficiency-oriented …

Has the Peripheral Delta Tunnel Canal Thingie paralyzed California water?

OtPR has a super insightful observation about three decades of California water policy: The Peripheral Canal was voted down in 1982.  My sense is that the possibility of the Peripheral Canal has largely paralyzed California water policy since then (with the possible exception of IRWM).  If the Peripheral Canal had been entirely off the table, the regions …
