Climate Change

Incorporating Drought Risk from Climate Change into California Water Planning, August 2, 2012.

This report, submitted to the California Department of Water Resources as comments on the draft Climate Adaptation Strategy, compared modeled projections of areas of increased drought under climate change with the  unprecedented droughts in Texas, New Mexico, Australia, and around the world.  The report discussed how in California, many climate change models predicted increased frequency and severity of droughts, as well as markedly reduced stream flow and reduced reservoir inflows. The report made specific recommendations for incorporating drought risk into climate modelling and planning by the Department of Water Resources.   The severe drought in the Southwest came to California the following year.


Mendota:  Evidence that Soil and Groundwater Salinization is the Predominant Cause of Land Fallowing

Compiled information from maps, satellite photos, USDA and other salinity
investigations, which showed that the greatest concentration of fallowed land in Westlands Water District in 2009 was near Mendota, and that the fallowing in that area was associated with severe soil and  groundwater impairment, and with land retirement. The district later admitted that 100,000 acres had gone out of production.
