Free, prior, and informed consent, or FPIC, is a crucial component of reducing emissions from deforestation and forest degradation in developing countries (REDD+) projects. This study addresses a significant research gap regarding FPIC in the context of REDD+ projects, with a focus on the Implementation of Governance, Forest Landscapes, and Livelihoods (I-GFLL) project in the Lao People’s Democratic Republic (Lao PDR). This research aimed to evaluate the FPIC’s components and implementation. We employed a literature review of the FPIC implementation reports from 242 targeted villages involved in the I-GFLL project and face-to-face interviews with 12 key informants. The research found positive aspects, such as female team membership, boosting ethnic women’s participation; the exclusion of forestry officials to foster an open dialogue; and respect for project rejections, displaying adherence to the FPIC principles. However, some challenging aspects were also highlighted, such as the exclusion of civil society organizations (CSOs) and non-government organizations (NGOs) and the loss of their expertise; limited team knowledge of forestry/climate change, hindering communication; short consultation durations; and an incomplete understanding of technical terms due to the project’s novelty, raising concerns. The study emphasizes the importance of crafting FPIC teams that promote communication, respect community rights, and, ultimately, ensure successful project implementation.
