Turkana County faces particular vulnerability to climate change, with warming temperatures and shifting rainfall patterns posing significant threats to pastoral livelihoods and threatening humanitarian crises. Global climate models project that the East African region, including Turkana, will experience warming of 1.5 to 2 degrees Celsius above pre-industrial levels by mid-century under moderate emissions scenarios and potentially 3 to 4 degrees Celsius under high-emission pathways. These temperature increases will amplify evaporation rates and intensify moisture stress in an already water-scarce region. Rainfall projections are uncertain, with some models predicting modest increases and others projecting decreases, but most agree that rainfall variability will intensify.
The impacts of climate change on Turkana's pastoral systems are already apparent and projected to intensify. Droughts have become more frequent and severe, with the 2010 to 2013 mega-drought, the 2015 to 2016 drought, and subsequent droughts devastating pastoral populations. These droughts kill livestock in massive numbers, destroy pasture and water resources, and create humanitarian emergencies requiring international assistance. Climate change is expected to increase the frequency of droughts above historical baselines, meaning pastoral communities will have insufficient recovery time between drought events. Water scarcity will intensify, affecting both livestock and human populations.
Climate change is creating cascading impacts across multiple sectors in Turkana. Agricultural activities become increasingly difficult with changing rainfall and temperature patterns, threatening food production for communities attempting agricultural transition. Fisheries face challenges from declining lake levels driven by reduced rainfall and potential temperature-driven changes in fish habitat suitability. Water supply systems, dependent on groundwater and surface water sources, face stress from reduced precipitation and increased evaporation. Health outcomes are threatened through multiple pathways: drought-driven malnutrition, water scarcity reducing hygiene practices, heat stress on human populations, and changing patterns of disease vectors.
The human dimensions of climate change in Turkana involve responses and adaptations at multiple scales. Pastoral communities are adapting through diversification of livelihood strategies, including engagement in trade, small-scale cultivation, and wage employment, reducing exclusive dependence on livestock. Herd composition is changing, with increased emphasis on camels and small stock that are more drought-resilient than cattle. Pastoral insurance schemes have been introduced, providing compensation for livestock losses during droughts. Water resources are being developed through expansion of boreholes and water harvesting systems.
However, adaptation capacity remains constrained by poverty, limited infrastructure, and governance challenges. While individual households and communities implement adaptations, systemic vulnerabilities remain. The underlying drivers of vulnerability, including poverty, inequality, and resource scarcity, are not being adequately addressed. Climate finance flowing to Kenya is insufficient to support comprehensive adaptation in vulnerable regions like Turkana. Turkana County's climate change challenge exemplifies the inequity inherent in global climate change: regions that have contributed least to emissions face disproportionate impacts.
