Payments for Environmental Services (PES), also known as Payments for Ecosystem Services, is a results-based financing mechanism to promote environmental conservation and restoration by the hands of local communities, farmers, and Indigenous communities, providing cash benefits for acting as custodians of nature. The publication explores the integration of digital technologies into Payments for Environmental Services (PES) schemes. The report underscores the potential of leveraging Digital Public Goods (DPG) and Digital Public Infrastructure (DPI) to enhance the scalability, efficiency, and effectiveness of PES programs. The research was conducted through interviews with UNDP practitioners, frontrunner countries with national PES schemes.
