The use of participatory approaches and methods in research, development, and humanitarian work has evolved in framing and content. Different terminologies have been used over time – Rapid Rural Appraisal (RRA), Participatory Rural Appraisal (PRA), Participatory Learning and Action (PLA), Participatory Appraisal (PA), and in the recent, the application of PA methods in animal health services and research dubbed as Participatory Epidemiology (PE).
