This study introduces a novel decision support web tool (doi.org/10.15140/D3J04K) to assist farmers and policymakers in managing salinity in California’s Central Valley. The tool integrates agronomic, economic and spatial data to predict crop yield and profitability under varying irrigation water salinity. This resource also supports policymakers and groundwater sustainability agencies in identifying areas where saline groundwater prevents profitable farming and prioritizing those areas for land repurposing to reduce agricultural water demand.
