West Pokot County experiences dramatic climate variation due to significant elevation differences. Lowland areas (below 1,200 meters) experience hot, semi-arid conditions with annual rainfall typically below 400-500 millimeters. Highland areas (1,500-2,500 meters elevation) experience cool, humid conditions with annual rainfall between 800-1,500 millimeters. Temperature decreases approximately 1 degree Celsius per 200 meters elevation gain. Maximum temperatures in lowlands can exceed 35 degrees Celsius, while highlands maintain moderate temperatures. Minimum temperatures in lowlands average 20-25 degrees Celsius, while highlands average 10-15 degrees Celsius. Rainfall is concentrated in two seasons (long rains March-June and short rains September-November). Rainfall variability creates significant uncertainty in pastoral and agricultural production.
Climate Impacts and Extremes
Drought cycles occur approximately every 3-7 years, creating pastoral crises and food insecurity. Severe droughts (early 2000s, 2010s, early 2020s) caused significant livestock losses and displacement. Heavy rainfall can cause flooding and waterlogging in lowland areas. Hail and windstorms occasionally damage crops in highland areas. Erratic rainfall (late onset, early cessation) disrupts planting and crop development. Climate variability affects water availability for pastoral and human consumption. Vegetation dynamics respond to rainfall patterns, supporting or limiting pastoral production. Water sources in lowlands depend on seasonal rainfall for replenishment. Highland water sources (springs, streams) are more reliable than lowland sources. Climate extremes create humanitarian needs requiring emergency assistance.
Climate Adaptation Responses
Pastoral mobility has traditionally been the primary adaptation to climate variability. Water point development in dispersed areas reduces drought impact concentration. Rangeland management aims to improve pastoral production resilience. Feed conservation (hay making, silage) supplements grazing during dry seasons. Drought-resistant crop varieties (sorghum, millet) are increasingly promoted. Livelihood diversification reduces dependence on climate-vulnerable pastoral production. Early warning systems and seasonal forecasts support adaptive management decisions. Water harvesting at community and household scales improves dry-season availability. Insurance products provide financial protection for climate-caused losses. Community-based rangeland management initiatives engage pastoral communities in land stewardship. Climate information services support pastoral decision-making.
