RT null T1 Some Methodological Issues in the Measurement, Analysis and Evaluation of Peasant Farmers' Knowledge of their Environment : A Research Memorandum - MARC Report Number 9 A1 United Nations Environment Programme, A1 Rockefeller Foundation, A1 Monitoring and Assessment Research Centre, A2 Barker, David K1 environmental education K1 farmer K1 environmental management K1 agricultural ecology YR 1977 FD 1977 LK https://wedocs.unep.org/handle/20.500.11822/28012 UL https://wedocs.unep.org/handle/20.500.11822/28012 NO This paper examines some of the problems involved in measuring and evaluating peasant farmers' knowledge of their environment and is an extension of the work of Barker. Oguntoyinbo and Richards (1977). That study presented a case for the utilization and inclusion of the perceptions of peasant farmers in the process of monitoring environmental change. Here, the problems of eliciting and evaluating this type of information in methodologically sound ways are discussed, drawing on earlier work in both ethnoscientific Third World studies and conventional behavioural research.
