The Guidelines aim to guide adaptation practitioners at national and local levels on how to take different steps when factoring ecosystems functions and services into countries’ NAP processes and instruments. The Guidelines detail the multiple benefits as well as the challenges of adopting ecosystem-based approaches to climate change adaptation; what information to collect and generate; what expertise to seek; and which stakeholders to engage for successfully integrating EbA into NAP formulation, implementation and review processes. The Guidelines have been developed under the NAP-Global Support Programme (NAP-GSP), implemented jointly by UNDP and UNEP that supports the Least Developed Countries (LDCs) in advancing their NAPs.
