Yield gap analysis of field crops. Methods and case studies

Abstract

The publication “Yield gap analysis of field crops: Methods and case studies” reviews 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 publication is a contribution to advance global water and food security through improvements in water and land productivity. It discusses methods to measure yield gaps, and ways to diagnose the root causes of yield and water productivity gaps and the actions that will be needed to close yield gaps in both small and large scale cropping systems, including management options and policies to provide incentives for the adoption of gap-closing technologies.
