The document evaluates the shortcomings of the current monitoring and evaluation (M&E) system for Payments for Forest Ecosystem Services (PFES), highlighting the absence of robust ecological assessments and unclear contract enforcement. It emphasizes the need for a well-structured M&E system to include baseline establishment, stakeholder engagement, and data collection protocols to effectively measure environmental and social impacts. Policy recommendations propose defining key performance questions, compliance thresholds, and clear reporting requirements to improve transparency and accountability within the PFES framework.
