Climate change is a major development challenge in sub-Saharan Africa. This region is highly vulnerable to negative impacts of climate change due to low adaptive capacity and overreliance on rain-fed agriculture for food security and livelihood. Climate information services (CIS) have been developed in Kenya to help enhance farmers' adaptation to climatic shocks, but their access and utilisation remain low. The factors that influence farmers' access and use of CIS are not well-known. Using survey data from a sample of 250 households in Makueni County, this study estimated a two-step Heckprobit model to analyse the determinants of access and use of CIS. Results showed that the age of the household head reduced the likelihood of accessing CIS whereas household size, income, farm size, livelihood activity, television ownership and group membership increased it. Age, sex of the household head, and frequent exposure to drought reduced the likelihood of using CIS whereas access to improved seed, household income, radio ownership, and livelihood activity increased it. Efforts promoting access to and utilisation of CIS would benefit by building trust among farmers through provision of accurate information; promoting adoption of improved varieties of crops; and providing incentives for formation and participation in farmers' groups.
