Short summary
Improving crop yield predictions is crucial for food security. Prior research relied on case studies, making it hard to compare methods and track progress. We introduce CY-Bench (Crop Yield Benchmark), a global dataset for forecasting maize and wheat yields across diverse farming systems in over 25 countries. It includes standardized weather, soil, and satellite data, curated by a diverse set of experts. CY-Bench supports the development of tools to help decision-makers plan for food security.
