Developing countries are increasingly granting local communities legal title to forests. Almost a third of forests in the global south are now managed by local communities, more than twice the share currently found in protected areas. However, we know little about the effects of titling on forest clearing and disturbance, which remain urgent problems. We use community-level longitudinal data derived from high-resolution satellite images, along with statistical techniques that control for confounding factors, to measure the effect of titling indigenous communities in the Peruvian Amazon. Results indicate that titling significantly reduces both clearing and disturbance, at least in the short term. The implication is that awarding formal land titles to local communities can protect forests.

Abstract

Developing countries are increasingly decentralizing forest governance by granting indigenous groups and other local communities formal legal title to land. However, the effects of titling on forest cover are unclear. Rigorous analyses of titling campaigns are rare, and related theoretical and empirical research suggests that they could either stem or spur forest damage. We analyze such a campaign in the Peruvian Amazon, where more than 1,200 indigenous communities comprising some 11 million ha have been titled since the mid-1970s. We use community-level longitudinal data derived from high-resolution satellite images to estimate the effect of titling between 2002 and 2005 on contemporaneous forest clearing and disturbance. Our results indicate that titling reduces clearing by more than three-quarters and forest disturbance by roughly two-thirds in a 2-y window spanning the year title is awarded and the year afterward. These results suggest that awarding formal land titles to local communities can advance forest conservation.
