Impact of SGMA on Crop Mix in California

Abstract

This was year one of a two-year project

Specific Objectives of the Project:

  • Collect data on soils, crops, production costs, and groundwater sustainability plans in the San Joaquin Valley.
  • Develop a mathematical programming model to allow simulation of optimal crop mix within and between groundwater sustainability agency (GSA) boundaries under alternative scenarios regarding irrigation water availability.
  • Simulate the effects of decreased water availability on crops grown in the San Joaquin Valley’s GSA’s.

Project Report/Summary of Results:
This first year of the project consisted of compiling geo-referenced data on crop production (yields and acreage), crop profitability, and groundwater sustainability plans, that are required to calibrate a spatially explicit programming model of crop supply in the San Joaquin Valley. We have decided that the decision unit in the model will be determined by GSA boundaries as they coincide with each GSA’s groundwater sustainability plans. We hired a post-doctoral student, Dat Tran, to lead our modeling effort. He will join us from the University of Arkansas once UCR is again accessible to faculty and staff.
