Mapping crop water use from space.
Remote sensing scientists at SAWS develop methods using satellite imagery to monitor evapotranspiration (ET) over California crops to better manage the state’s water resources. To the right is an image showcasing satellite-derived ET over the Central Valley and the spatial variability in crop water use commonly found field to field (magnified circle).
Mission
The mission of the SAWS unit is to increase the efficiency and sustainability of irrigated agriculture in California under changing environmental conditions, with a special focus on vine and tree orchard crops in the Central Valley. This is accomplished by: (i) improving irrigation efficiency; (ii) optimizing on-farm strategies for managed aquifer recharge; (iii) assessing the long-term impacts of irrigated agriculture on crop production, soil health, and groundwater quantity and quality under changing environmental conditions; and (iv) support and enable climate-informed decision making for working and natural land managers by co-developing resources, translating information, and assisting with the implementation of science-based tools and technologies that lead to greater climate resilience and support carbon neutrality.
