The study aimed to achieve three main objectives: (1) to assess how residents of Marsabit County perceive climate change, (2) to evaluate the impact of climate change on security in the county, and (3) to identify the adaptation strategies employed by the local population in response to climate-related challenges. A mixed-methods design was used, integrating both quantitative and qualitative approaches. The research was conducted across the four sub-counties of Marsabit County—Laisamis, Saku, North Horr, and Moyale. ” Participants were drawn from a range of groups, including pastoralists, business owners, government and county officials, and staff from humanitarian organizations active in the area. Snowball and purposive sampling techniques were employed to select participants, with data collected through questionnaires and interviews. The analysis included both thematic and statistical methods. Ethical standards were maintained by securing informed consent from all participants before their involvement in the study.The findings revealed that pastoralism is the primary livelihood for most residents of Marsabit County. Climate change has adversely affected livelihood security by decreasing the availability of water and pasture, leading to heightened competition and land encroachment. This has consequently intensified conflict and insecurity within the region. ” To mitigate these challenges, local communities have diversified their economic and social activities, thereby reducing their reliance on pastoralism.The study recommends conducting further research on the effects of climate change on security in other counties to broaden the understanding and applicability of the findings.enThesis
