In this paper, we study how deforestation in West Africa affects economic development in locations distant from where tree losses occur. Clouds passing over recently cleared areas accumulate less water, leading to a reduction in rainfall downwind. Using satellite data, we exploit wind patterns in the region to quantify the effects of this externality on key development indicators. We find significant negative effects on rainfall up to 200 km from deforested regions. Additionally, we observe a decrease in GDP and an increase in out-migration in rural areas, whereas in urban areas, both GDP and the number of demonstrations rise. Our results underscore the importance of spatial interdependencies in natural ecosystems across developing regions.
