Participatory research methods in environmental science: local and scientific knowledge of a limnological phenomenon in the Pantanal wetland of Brazil (original) (raw)

2000, Journal of Applied Ecology

1. Participatory research methodologies incorporating local knowledge are important to the success of ecological research and the sustainable management of natural systems. However, methods of this type are not commonly employed in the natural sciences. 2. We adopted a scienti®cally rigorous ethnographic research methodology to incorporate local knowledge into understanding a natural limnological phenomenon in the Brazilian Pantanal. Known locally as`dequada', it is associated with ®sh kills. 3. Using primarily open-ended questions and semi-structured interviews, 30 older head-of-household men were interviewed, by the same interviewer, in a small community representative of the few local riverside settlements. Their opinions were then contrasted with current scienti®c knowledge. 4. In concordance with the scienti®c community, the local community cited decomposition of organic material as the principal cause of ®sh mortality due to the dequada. Local people therefore can have a well-founded understanding of their environment. 5. This study demonstrates the importance of incorporating local knowledge to corroborate and, often, to guide the process of scienti®c inquiry. In this case, local knowledge added to scienti®c knowledge by providing a more complete understanding of the management and conservation of a natural system. We recommend that ecologists should be ready to acknowledge that local understanding can be greater than that of`outsiders'.
