Abstract: Climate change and food security are two of the most pressing challenges facing the global community today. Improving smallholder agricultural systems is a key response to both. Given that agriculture is the key economic sector of most low-income developing countries, improving the resilience of agricultural systems is essential for climate change adaptation. Kitui County is characterized by low and declining crop productivity. It is particularly susceptible to climate change due to its over-reliance on rain-fed agriculture, aridity, inadequate water supply and degradation of many of its natural resources. This study examined the influence of Climate Resilient Agriculture on food security in Kitui County.
