This document summarizes a training workshop on payments for ecosystem services (PES) and reducing emissions from deforestation and degradation (REDD+). It discusses key elements of PES agreements including structuring the agreement, either as a purchase of ecosystem credits or a contract for ecosystem services. It also covers negotiating PES contracts and special considerations, such as ensuring free, prior and informed consent of stakeholders. PES agreements can vary in formality from oral agreements to complex, legally-binding written contracts depending on the specific ecosystem service and transaction complexity.
