San Joaquin Valley farms and Southern California cities are facing different but equally daunting water challenges. For Valley farmers, the requirement to achieve groundwater sustainability in coming years has heightened interest in expanding water supplies to reduce the need to fallow irrigated farmland. For Southern California, falling demands since the early 2000s have reduced water stress during normal and wet years, but a warming climate makes future droughts a major concern. Both regions’ water futures could be more secure if they jointly developed and managed some water supplies.
