Climate change and variability are affecting weather patterns and causing seasonal shifts with serious repercussions for households and communities in Kenya. The livelihoods of the majority of Kenyans are therefore threatened due to the potential adverse impacts of climate change, such as declining production and productivity, which could lead to food insecurity. To mitigate the negative impacts of climate change and variability, farmers need to adopt different strategies, such as new crop varieties, crop and livestock diversification, and water-harvesting technologies. These climate change adaptation strategies are expected to influence the level of food production (hence food security) in the country, and therefore their linkages with food security in Kenya need to be studied. It is against this background that this study was undertaken to assess factors influencing climate change adaptation and the implications of adaptation for nutrition, measured in kilocalories (Kcal) produced. To accomplish this task, an endogenous switching regression model is applied to household survey data of 708 households from 38 counties in Kenya.
