Global Yield Gap Atlas

Decision-making abilities for your next investment in agriculture are only as good as the data in front of you.

The world's leading database on high-quality agronomic data with local to global relevance that covers up to 13 major food crops across 70 countries and six continents with the following data:

  • actual and potential yield and yield gap
  • actual and potential water productivity
  • actual and minimum nutrient requirement
  • underlying data on weather, soil and cropping systems
  • climate zones and technology extrapolation domains (TEDs).

The data serves research, strategic decision making and local-global actions that aim to improve yield and resource use efficiency by public and private sectors.

UPDATE: GYGA got featured in the recently-published 2022 Sustainable Development Report by the Sustainable Development Solutions Network (SDSN)! Check out the 'Yield Gap Closure' indicator in the SDR 2022 here!

Our product and service

The GYGA platform - what makes GYGA a unique database?

  1. All-in-one data management platform
  2. High-quality and locally-relevant data collected by agronomists from well-known institutions in each country following a common protocol with a solid agronomic foundation
  3. A bottom-up approach from local level up to region and country
  4. Data are available at different spatial levels: weather station, climate zone and national levels
  5. The database can be readily expanded with additional crops and countries.

Currently, the country by crop combinations included in GYGA account for 88%, 76%, 55% and 71% respectively, of the global rice, maize, wheat and soybean growing areas.

Research expertise by the GYGA team

The GYGA team (University of Nebraska-Lincoln and Wageningen University & Research) consists of world-leading scientists on agronomy and resource use efficiency who will be happy to support you to achieve your goals. We always work in collaboration with country agronomists from reputable institutions with knowledge on production systems, soils, and climate to ensure local relevance and a strong agronomic foundation. See our partners across the globe here.

Possible areas of future research include:

  1. Addition of new countries or crops of specific interest
  2. Scenario studies on food security, land use, climate smart agriculture or resource use efficiency for specific regions, countries or the globe
  3. Ex-ante impact assessment of agricultural technologies
  4. Ex-post impact assessment of R&D investments.

“It is our ambition to add indicators on water use efficiency and nutrient use efficiency with the best available (agronomically robust) data. The Atlas can deliver this. It is also SDSN’s ambition to publish such indicators annually to monitor progress of realising the SDGs. Hence frequent updates of data are critical." “The Atlas has the potential to be an important diagnostic tool for evidence-based policy dialogue, policy making and policy implementation around different SDGs, particularly also for developing countries. The expansion of the global data is critical for applications in integrated agriculture and land management, raising productivity in a sustainable manner."

GYGA has come a long way. GYGA started as a research project in 2011, and it has now transitioned into a first of its kind database that provides high-quality and locally-relevant data on yield gaps and agronomic data used by thousands across sectors (companies, public, research institute-academia, NGOs).

In order to grow into a comprehensive and self-sustaining global database, we are looking for your contribution to determine the future development of GYGA and bring the platform to the next level!
