Crop Yields and Forest Conservation in the Tropics: Systematic Evidence from Billions and Trillions of Satellite Measurements 1: University of Bonn, Germany; 2: World Bank Understanding how crop yield changes affect forest conservation in tropical regions is central to achieving both food security and environmental sustainability. While existing evidence is primarily based on case studies, systematic evidence at broad spatial and temporal scales remains limited. We combine high-resolution (30 × 30 m) satellite data covering the entire tropics annually from 2001 to 2022 to estimate the local effects of crop yield changes on forest cover. Using a dynamic panel framework, we find modest but statistically significant forest loss following yield gains. On average, approximately eight percent of local forest loss can be attributed to local yield increases in the tropics. Effects are heterogeneous and concentrated in more accessible areas with higher initial forest cover, a certain balance between land availability and incentive for expansion, and few agri-environmental policies. Regions with mostly smallholder farming (even defined up to 20 ha) as well as those with broad agroforestry adoption do not lose any forest on net in response to crop yield gains. The strongest negative effects are observed in Sub-Saharan Africa and in Latin America, respectively, whereas we do not find an effect in Asia. | |
