Water is the defining constraint of life in Samburu County, a vast semi-arid landscape in northern Kenya where rainfall is erratic, rivers are seasonal, and the availability of water dictates the movement of people and livestock across the rangelands. The Ewaso Nyiro River, rising from the Aberdare Range and Mount Kenya's northern slopes, is the single most important water source for the Samburu and neighbouring communities. Its flow sustains riverine forests, wildlife populations in the Conservation areas of Samburu and Buffalo Springs national reserves, and the pastoral economy that remains the foundation of Samburu livelihoods. Yet the Ewaso Nyiro is increasingly stressed: upstream abstraction by commercial horticulture farms in Laikipia and Nanyuki, combined with deforestation in its catchment areas, has reduced dry-season flows to critical levels.
Drought is not an aberration in Samburu but a recurring feature of the climate cycle, occurring with devastating regularity every three to five years. The droughts of 1984, 2000, 2009, 2011, and 2017 each killed tens of thousands of livestock - the primary wealth and sustenance of Samburu pastoralists - and pushed communities into dependence on food aid. Climate change has intensified drought frequency and severity, compressing recovery periods and eroding the resilience of pastoral systems that evolved over centuries to manage variability. The loss of livestock during drought triggers cascading social effects: children drop out of Education, families fragment as men move with surviving herds, and nutritional crises overwhelm local Health Services.
Borehole development has been a central strategy of successive Kenyan governments and international NGOs seeking to improve water access in Samburu. Boreholes provide reliable groundwater in areas far from surface water, enabling settlement and reducing the distances women and children walk daily to fetch water. However, borehole placement has also generated conflicts. Permanent water points attract concentrated livestock populations that degrade surrounding rangelands, creating desertification rings visible from satellite imagery. Competition for borehole access has fuelled tensions both within the Samburu community and between Samburu herders and neighbouring Turkana and Pokot pastoralists, occasionally escalating into armed raids and livestock theft.
Herder-farmer conflicts along the Ewaso Nyiro corridor and in the Leroghi Plateau reflect the broader pressures on water resources. As Agriculture expands into formerly pastoral areas - driven by population growth, land subdivision, and government settlement schemes - the competition between crop irrigation and livestock watering intensifies. The 2017 Laikipia Invasions, in which armed herders drove cattle onto private ranches during drought, illustrated how water and pasture scarcity can become a trigger for violent confrontation. Water governance in Samburu remains fragmented, split between national agencies, county Government structures created under Devolution Kenya, and customary institutions whose authority over resource management predates the modern state.
