The document discusses participatory rural appraisal (PRA), which is a methodology for collecting data in rural communities through participatory techniques. It was developed as an alternative to the top-down rapid rural appraisal approach. PRA emphasizes local community participation, empowerment, and mutual learning between outsiders and community members. The core features of PRA include voluntary involvement of local people, participation in decision making, and improving community well-being. Some commonly used PRA techniques described in the document include transect walks, social mapping, seasonal mapping, daily activity charts, Venn diagrams, problem prioritization, and group discussions.
