A global comparison of the biodiversity impacts of coffee agricultural systems––From monoculture to diverse agroforestry

Summary

Coffee is an important tropical crop with growing demand and intensification, combined with increasing public interest in the sustainability of production methods. Shade grown coffee, or agroforestry coffee, is often seen as an environmentally friendly alternative to monocultures. However, it encompasses a wide range of growing strategies with little known about the extent to which they differ in biodiversity impact. Here we build a comprehensive dataset from existing literature on species richness loss associated with a range of coffee management strategies to better understand the effect of coffee management practice on biodiversity. We use meta-analysis methods and mixed effects models to determine the extent to which five coffee management strategies, from monoculture to diverse agrofo
