West Pokot County has dramatic topographical variation, transitioning from hot, arid Rift Valley lowlands to cool, well-watered highlands. The landscape ranges from approximately 1,000 meters elevation in the south to over 2,500 meters in the northern highlands. The Cherangany Hills form the eastern boundary, creating a major water tower and highland zone. Mount Sekerr and other peaks dominate sections of the landscape. The county is bounded by Uganda to the west and south, and by Turkana County to the north. River systems (Turkwel, Suam, Weiwei) drain the highlands toward the lowlands and eventually into larger water systems. The terrain includes escarpments, gorges, and river valleys creating complex topography.
Ecological Zones and Climate
The hot lowlands support pastoral production with sparse vegetation adapted to aridity. Rainfall in lowlands is often below 400 millimeters annually, creating desert-like conditions. The highland zones receive substantially higher rainfall (800 to 1,500 millimeters), supporting agricultural production. Temperature decreases with elevation, creating cool highlands favorable for crop cultivation. Seasonal rainfall patterns drive pastoral movement seeking water and grazing. The rainy seasons (long rains March-June, short rains September-November) are critical for pastoral production. Dry seasons create pastoral stress and water scarcity. Water sources include seasonal rivers, permanent springs, and hand-dug wells. Lake-like water bodies exist in some lowland areas, providing pastoral water sources.
Resource Distribution and Implications
Water is the most critical limiting resource in lowland pastoral zones. Pasture distribution determines pastoral settlement and seasonal movement patterns. Highland areas have fertile soils suitable for crop cultivation. Forest patches provide timber, firewood, and medicinal plants. Wildlife distribution includes large animals in lower elevations and smaller species in highlands. The dramatic geography creates distinct livelihood zones and economic disparities. Highland communities engage in agriculture and have better access to services. Lowland pastoral communities have more limited service access and face greater environmental stress. Geographic isolation of some areas creates connectivity and service delivery challenges. Topography influences road infrastructure feasibility and maintenance costs.
