Starting in 1997, Tegemeo Institute and MSU have designed, implemented,
household-level surveys to provide an objective vantage point for discussions
on agricultural policy and poverty reduction strategies. The sample covered
approximately 1,500 households in 24 districts in 1997, 1998, and 2000.
Census data was used to find the populations of all non-urban divisions
in the country. The populations in all these divisions were assigned to
one or more agro-ecological zones (AEZ) based on secondary data1 and in-house
experience. This process resulted in dividing Kenya's rural population
into its make up by AEZ. Within each AEZ, two or three divisions were chosen
on the basis of their importance (population) within their AEZ. Diversity
in cropping patterns was allowed to influence the selection of divisions
where it was not clear which divisions to choose. These divisions fell
within 24 districts of the country. Details on the sampling procedure can
in Argwings-Kodhek et al (1999), "How Can Micro-level Household Information Make
a Difference for Agricultural Policy Making? Selected Examples from the KAMPAP
Survey of Smallholder Agriculture and Non-Farm Activities for Selected Districts
in Kenya," which is viewable and downloadable in the "Conference Papers" section
of this site.
