Drought poses a critical threat to global water and food security. Thus, there is an urgent need to develop advanced methodologies for accurately assessing water security. This requires integrating cross-sectoral approaches that address both large-scale drivers of water availability and their local impacts on systems such as irrigation districts and river basins. Coupling water availability assessments with information on food production is critical to gaining a comprehensive understanding of food security challenges. The availability of high-quality, representative datasets on water and food security is essential for supporting global water management strategies. Under the TERESA project we aim to harness Earth Observation data and agro-hydrological models to pioneer new methods for drought sensing, water balance monitoring, crop yield estimation, and the development of water-food security metrics. These efforts are expected to enhance management strategies for sustainable food systems and agriculture.
