 This research examines the impacts of road construction and infrastructure improvements on land cover change in a tri-national border region between Peru, Brazil and Bolivia. It finds that road paving leads to increased deforestation rates, with the highest rates occurring near the roads themselves. Additionally, the rate of deforestation decreases with distance from the roads, suggesting that the effects of road paving extend beyond the immediate area.
