Growing fruit trees on smallholder farms can contribute a lot to income generation and nutrition security for the farming households. Fruit tree species richness and diversity, however, are influenced by many biophysical and socio-economic factors. Programs aiming at promoting cultivation and consumption of fruits need to understand and consider these factors. To identify influencing factors and their complex interactions, a baseline survey of 300 randomly selected households was performed in four agro-ecological zones in Machakos County, eastern Kenya. Households were selected from three strata/groups; one group exposed to a programme promoting fruit cultivation ('FRUIT'), one group exposed to a hygiene programme ('WASH') and one other group not exposed to any programme ('Control'). Interviews were performed to gather basic socio-economic data and information on the fruit species and tree individual numbers per farm. Statistical analyses included U- and H-tests, correlation and regression analyses.
