Abstract: Food insecurity is a concern for households and government. It destabilizes social, economic and political wellbeing. Despite Kenya’s government efforts in provision of incentives like climate smart subsidies to address food insecurity, Makueni County still experiences food deficit. This article focuses on effects of climate smart agriculture technologies on household food security. Findings revealed improvement in food security as 21.8 per cent households were food secured compared to 2 percent in 2012, attributing to existence of climate smart fund. From findings, access to farm input and practising Agroforestry increases crop yields and thus food availability, accessibility and affordability.
