• In comparison with Indonesia, Uganda and Nepal, Peruvian law provides a weak mandate for tenure reform implementers to address conflict, and Peru has the lowest number of implementing officials stating that addressing conflict is among their responsibilities. • In the villages studied, Peru reports the highest proportion of villagers involved in land or forest conflicts, the highest proportion with actors external to the community and the lowest portion resolved. • Despite the legal significance of a land title, collective titling alone does not assure the end of land/forest disputes with outsiders. The state needs to defend the property rights that it has recognized. • Peru must improve its legal framework for conflict management in land/forest disputes both in and after formalization processes, drawing on state and customary, community or alternative mechanisms.
