Agriculture consumes more than 70% of global freshwater and remains a major source for water pollution. Improving agricultural water and land management can help reduce water footprint of agricultural production and restore healthy watersheds. This session explores science, technology, and policy at the water-agriculture nexus, emphasizing systems-based and interdisciplinary approaches. We invite contributions on: (1) process-based insights in integrating agronomic and conservation practices, hydrological processes, biogeochemistry, and socioeconomic dimensions to better understand and manage connections between agriculture and natural water systems; (2) new sensing and data-driven techniques to monitor agricultural water use, soil health, and ground- and surface water quality; (3) advanced systems modeling and model-data integration for improved quantification; (4) decision support systems to co-create solutions with stakeholders and translate science into practice for sustainable land and water management; and (5) policies, market mechanisms, and socioeconomic issues grounded in stakeholder engagement that promotes more effective water governance in agriculture.
