This document discusses participatory rural appraisal (PRA) and related methodologies. PRA involves local communities in the assessment of their needs and resources through participatory techniques. It aims to gather qualitative information in a bottom-up, flexible manner. Some key PRA techniques discussed include participatory mapping, seasonal calendars, wealth rankings, and semi-structured interviewing. PRA seeks to overcome some limitations of earlier rapid rural appraisal approaches by increasing participation and incorporating local knowledge. Related methodologies like participatory technology development also take collaborative, community-based approaches.
