Highlights
► We define the concepts relevant for yield gap analysis. ► We review different methods for local and global yield gap analyses. ► Global methods are coarse and local studies use different methods. ► A number of methods is compared using data sets from three regions. ► Components of a protocol for global yield gap analysis with local relevance are proposed.
