AquaCrop on the ground: Model applications for sustainable agricultural water management

Efficient agricultural water management is essential in addressing global challenges like water scarcity, climate variability, and increasing food demand. AquaCrop, a crop–water productivity model developed by FAO with leading scientific institutions, offers an innovative, research-driven approach to optimize water use and boost crop yields. Designed for water-limited conditions, AquaCrop provides actionable insights for farmers, policymakers, and researchers to improve water-use efficiency. Since its 2009 launch, it has been widely praised for its simplicity, scientific rigour, and adaptability to different agroecological contexts.This report highlights real-world applications of AquaCrop, showcasing its effectiveness in arid regions with water shortages and areas with excess moisture. These examples demonstrate AquaCrop’s versatility in optimizing irrigation schedules, supporting decision-making, and promoting sustainable agricultural intensification. The report also emphasizes the value of collaboration among FAO, national agricultural agencies, research institutions, and farming communities.By integrating climate-smart practices, AquaCrop contributes to food security, environmental sustainability, and economic stability. It enhances resilience to climate change, supports sustainable resource management, and fosters evidence-based decision-making. This report underscores FAO's commitment to advancing practical solutions for agricultural water management and aims to inspire further collaboration and innovation to ensure sustainable water use in agriculture for future generations.
