The Kalenjin highlands (Mau Forest, Cherangani, Nandi Hills) form Kenya's critical water towers, providing water to arid and semi-arid lowlands. However, extensive encroachment by settlers (including Kalenjin politicians allocating forest land to supporters) has led to massive deforestation, triggering a 2009-2010 eviction that devastated thousands while failing to permanently stop encroachment.
Water Tower Geography
The Kalenjin highlands, including the Mau Forest complex, Cherangani range, and Nandi Hills, receive substantial rainfall and retain water in forests, soil, and groundwater. The water infiltrates slowly into rivers and springs that supply water to surrounding lowlands.
This water source supports pastoral communities below the forests, agricultural zones, and downstream populations including urban centers. The highlands' function as water tower is critical for Kenya's water security.
Mau Forest Complexity
The Mau Forest complex is extensive, covering over 400,000 hectares, with portions within Kalenjin territories. The forest provides watershed function, biodiversity habitat, and local livelihood resources including timber and firewood.
Historically, colonial and post-colonial logging targeted Mau Forest, with government agencies and private concessionaires extracting timber. This logging degraded forests, though the forest retained basic function.
Settler Encroachment and Illegal Settlement
From the 1990s onward, Mau Forest experienced accelerating settler encroachment, with individuals clearing forest for agriculture and settlement. Some encroachment was small-scale squatting, while other encroachment involved politicians allocating forest land to supporters.
Kalenjin politicians, using state authority, allocated Mau Forest land to constituents as patronage. These allocations converted forest to private farms, destroying the forest structure. The encroachment was neither random nor inevitable but systematic allocation by politicians for political support.
By the 2000s, extensive portions of the Mau had been cleared for agriculture, particularly tea and maize farming. The ecological consequences were severe: reduced forest cover, degraded water retention capacity, and loss of biodiversity habitat.
Environmental Crisis and 2009-2010 Evictions
By 2008-2009, the environmental crisis became critical. Drastically reduced forest cover meant that water retention was compromised, and downstream water availability was severely reduced. The government, responding to the crisis and pressure from environmental groups, announced evictions of encroachers from the Mau.
In 2009-2010, large-scale evictions removed tens of thousands of settlers from the Mau. The evictions were often violent and traumatic, with little compensation or relocation support provided to evicted settlers. Families lost their farms and homes, facing economic devastation.
The evictions were controversial because they targeted small settler-farmers while high-ranking politicians who had allocated large forest tracts often escaped accountability. The burden of eviction fell disproportionately on poor settlers rather than on powerful politicians.
Incomplete Recovery and Renewed Encroachment
Despite the evictions, the Mau has not fully recovered. Some of the cleared forest has not regenerated due to continued pressure and degraded soil conditions. New encroachment has occurred in some areas as enforcement of forest protection has been inconsistent.
The fundamental problem,that forest protection is undermined by politicians' interest in allocating land as patronage,has not been resolved. Forest protection requires sustained political commitment that must overcome politicians' short-term interest in using forest land for patronage.
Climate Change and Water Availability
Climate change is affecting Kalenjin highlands through changing rainfall patterns and temperature increases. Glaciers that existed on mountain summits have melted due to warming. Rainfall patterns are becoming more variable, with increased drought periods interspersed with intense rainfall.
These changes compound forest degradation impacts, reducing water availability in the region. Downstream communities face increasing water scarcity for agricultural, pastoral, and domestic use.
Community and Livelihood Impacts
Forest encroachment has affected Kalenjin communities relying on forest resources. Communities with traditional rights to forest access have seen those rights restricted by privatization and settlement. Young men who might have relied on forest livelihood have lost access.
However, the settlers clearing forest for agriculture have also been Kalenjin, creating internal Kalenjin conflict between forest conservation and land access for settlement and farming.
