Abstract
Reduced surface water supplies in the Southern San Joaquin Valley of California in recent years have forced growers to make difficult decisions regarding cropping, irrigation practices, and groundwater use. There is interest in objectively quantifying economic and hydrologic impacts of these reductions at levels ranging from locally-affected communities to the State and Federal governments. However, the ability to analyze impacts is limited by the unavailability of timely disaggregated data. This paper explores the opportunity to apply satellite remote sensing of crop evapotranspiration and biomass production to increase information available and perform objective analysis of the actual economic and hydrologic impacts incurred.
