Yield Potential and Yield Gap Atlas (YPYGA)
The world's leading agronomic database with local to global relevance covering the world’s most important staple food and vegetable oil crops across 83 countries and six continents with the following data:
  • Actual and potential yield and yield gap.
  • Actual and potential water productivity.
  • Underpinning data on weather, soil and cropping systems.
  • Bottom-up spatial aggregation based on climate zones and technology extrapolation domains (TEDs) to evaluate crop and soil management practices, identify yield-limiting constraints, and to inform research prioritization in both the public and private-sectors

Short History
YPYGA was initiated in March 2026 to continue the tradition of the Global Yield Gap Atlas (GYGA). From 2011 to 2025, GYGA scientists from the University of Nebraska and Wageningen University and Research developed improved methods for estimating local to global crop production potential and the gap between that potential and today’s average farm yields (link to publications). A coordinated international effort enabled substantial global coverage for wheat (60% of global wheat production), rice (88%), maize (77%), and soybean (95%), among other crops.
YPYGA is built on the knowledge and data contributions from a global network of agronomists who understand the importance of accurate yield potential and yield gap data from local to national scale for all major food crops (link to contributors).
The new Atlas
The previous Global Yield Gap Atlas (GYGA) has transitioned into the Yield Potential and Yield Gap Atlas (YPYGA).
The Atlas is a comprehensive and self-sustaining global database with local to global agronomic rigor for the benefit of thousands of public and private data users.
