Multi-Subject Farm Surveys Reconsidered: Some Methodological Lessons
It draws on the experience of the author with regard to socio-economic surveys carried out in Kenya and elsewhere in East Africa. It considers problems in sampling, farmers' responses, the interview situation, survey staff, and various problems with regard to recording accuracy and data processing. The paper concludes by noting 20 key aspects that should be taken into account when designing surveys. These include: (1) careful selection and training of staff; (2) the importance of learning the farming systems in advance; (3) where possible to choose farmers for whom the key parameters are known from other sources; (4) utilize at least one full time supervisor resident in the survey area with independent transport; and (5) allow two thirds of the total period for activities other than the field survey, ie. data processing.
