FAO, Water for Food Institute publish global yield gap analysis report

June 23rd, 2015


To feed a world population that is expected to exceed nine billion by 2050 requires an estimated 60 percent increase over current agricultural productivity. Closing the gap between actual and potential crop yield is critical to achieve this goal.

A new report published jointly by the Food & Agriculture Organization of the United Nations and the Robert B. Daugherty Water for Food Institute at the University of Nebraska reviews current methods for yield gap analysis, clarifying definitions and techniques to measure and model actual, attainable and potential yield at different scales in space and time and using case studies to illustrate different approaches. The report builds on the activities of FAO and the institute to develop tools and knowledge delivery systems to better inform and guide policymakers in managing water and agriculture. Two major initiatives are at the foundation of this publication: the Global Yield Gap Atlas (led by the institute) and the Regional Initiative on Water Scarcity for Near East and North Africa (led by FAO).

The report is co-authored by Water for Food Institute Faculty Fellows Ken Cassman and Patricio Grassini, as well as the institute’s International Advisory Panel member Pasquale Steduto, among others.
