PACA (Participatory Analysis for Community Action) is the core approach to support participatory, sustainable development. You'll use PACA throughout your service to identify community needs, co-create solutions, and implement meaningful, community-led projects. Volunteers apply PACA throughout service to brainstorm, design, implement, and improve projects with community members. The PACA Field Guide outlines the five phases of moving from participatory analysis to community action and provides practical tools for each step.
