CIMIS conserves water and increases water availability for urban users
CIMIS station in the Mexicali Valley- CIMIS helps growers in the region to develop crop water budgets for determining when to irrigate and how much water to apply
What Has ANR Done?UCCE initiated and coordinated meetings between scientists from California Department of Water Resources, University of Baja California, and the state of Baja California to install and calibrate two CIMIS weather stations in the Mexicali Valley. UC scientists developed bilingual computer programs and publications that are used to educate growers in the region about how they can improve water use efficiency and increase the availability of Colorado River water to urban areas in Southern California and northern Baja California.
Mexicali Valley CIMIS weather station and bilingual information cut water useThe additional weather stations and irrigation scheduling programs help growers in both Baja California and Southern California conserve water. Growers in California extensively use evapotranspiration information from CIMIS. Parker et al. (California Agriculture journal, 2000) estimated that California growers save approximately $64.7 million per year in water and energy savings by using CIMIS. The estimated benefit to growers in our region is $6.5 million in water and energy savings. In addition to water savings, reduction in agricultural water use also reduces fertilizer usage and surface and ground water pollution. In light of this data, our best management practices to conserve water and improve irrigation efficiency were included in Regional Water Quality Control Board - Region 7 Silt/Sedimentation TMDL standards.
