Adoption levels of agroforestry tree types and practices by smallholders in the semi-arid areas of Kenya: A case of Makueni County

Abstract

A survey targeting smallholder households was carried out in Mumbuni and N dovoini sub - locations in the semi arid Makueni County , Kenya, to identify agroforestry types and practi ces and their level of adoption and socio - economic factors influencing adoption of agroforestry . The study involved a survey of 234 ho u sehold s using a st ructured questionnaire. The collected data was subjected to descriptive statistical analysis and binary logistic regression model . Results obtained revealed that more than 90% of the households practised agroforestry. It was also observed that significantl y (P<0.01) more agroforestry trees in overall were planted at Mumbuni (40 trees/acre) than at Ndovoini (9 trees/acre). Agroforestry annually contributed 41 and 17% of farm - based income in Mumbuni and Ndovoini, respectively. Adoption of agroforestry was sig nificantly influenced by the size of the household, mode of acquisition of land, security of land tenure, size of landholding, gender and the level of education of the head household . Adoption of sustainable agroforestry practices was low in both sites. Th ere were 50 to 58% of households with fruit trees dispersed on crop land; the other practices on fruits were poorly being carried out (<20%). The highest practices on forest wood trees were homestead planting (Mumbuni 40.2% and Ndovoini 70.1%); the rest we re poorly adopted (<25%). Agroforestry practices on fodder were least adopted (<16%).
