The management of rangelands, including climate change adaptation strategies, is primarily responsible for stimulating livestock productivity, which consequently improves food security. This paper investigates the impact of climate change adaptations on food security among pastoralists in semi-arid parts of Kenya, who have not received due attention to date. Using an endogenous switching regression model, the current study revealed that pastoralists’ food security increased significantly when they employed measures to adapt to climate change. The study results also showed that wealthier households and those with more livestock were more food-secure than comparatively poorer households or those with less livestock. Furthermore, the study uncovered a high prevalence of food security among more educated households. The paper therefore recommends that, in Kenya’s semi-arid lands, where pastoralism is the primary means of livelihood, policies advocating adaptations to climate change should be strengthened. Also fundamental to building pastoralists’ adaptation strategies are the consistent monitoring of climate change, the use of early warning systems, and the communication of pertinent information to farmers—and particularly to pastoralists.

牧场管理，包括气候变化适应战略，主要负责刺激牲畜生产力，从而提高粮食安全。本文调查了气候变化适应对肯尼亚半干旱地区牧民粮食安全的影响，这些牧民迄今尚未得到应有的关注。使用内生转换回归模型，目前的研究表明，当牧民采取措施适应气候变化时，他们的粮食安全显着增加。研究结果还表明，与相对较贫穷或牲畜较少的家庭相比，较富裕的家庭和拥有更多牲畜的家庭的粮食安全性更高。此外，该研究还发现，受教育程度较高的家庭普遍存在粮食安全问题。因此，该文件建议，在肯尼亚的半干旱地区，以畜牧业为主要谋生手段，应加强倡导适应气候变化的政策。建立牧民适应战略的另一个基础是对气候变化的持续监测、预警系统的使用以及向农民（尤其是牧民）传达相关信息。
