Proxydetection of the impact distance of trees on crops: An indicator of the Land Equivalent Ratio? Agric. Ecosyst. Environ. 394, 109918. https://doi.org/10.1016/j.agee.2025.109918 Description: This repository provides the codebase used to generate the analyses, figures, and key metrics presented in Agbohessou et al. (2025). The code implements the proxydetection framework developed to quantify the spatial influence distance of agroforestry trees on crop performance and derive spatial proxies for the Land Equivalent Ratio (LER). It provides also a tutorial of the geomatics chain.
