Participatory Rural Appraisal (PRA) describes a growing family of approaches and methods to enable local people to share, enhance and analyze their knowledge of life and conditions, to plan and to act. PRA has sources in activist participatory research, agroecosystem analysis, applied anthropology, field research on farming systems, and rapid rural appraisal (RRA). In RRA information is more elicited and extracted by outsiders; in PRA it is more shared and owned by local people. Participatory methods include mapping and modeling, transect walks, matrix scoring, seasonal calendars, trend and change analysis, well-being and wealth ranking and grouping, and analytical diagramming. PRA applications include natural resources management, agriculture, poverty and social programs, and health and food security. Dominant behavior by outsiders may explain why it has taken until the 1990s for the analytical capabilities of local people to be better recognized and for PRA to emerge, grow and spread.
