Spatial frameworks for robust estimation of yield gaps
J. I. R. Edreira, J. F. Andrade, et al.
This paper reveals that commonly used top-down frameworks for estimating crop yields, such as GAEZ and AgMIP, may actually underestimate production, sometimes providing lower figures than what farms currently achieve. Authors Juan I. Rattalino Edreira, José F. Andrade, Kenneth G. Cassman, Martin K. van Ittersum, Marloes P. van Loon, and Patricio Grassini emphasize the importance of using bottom-up approaches for more reliable food security assessments, especially in regions like sub-Saharan Africa.
