Kenya's Climate Emergency: Five Consecutive Failed Rainy Seasons Push Millions to the Brink

The parched earth of Turkana County, in Kenya's arid and semi-arid north-west, tells a story that statistics alone cannot capture. Cracked riverbeds stretch for kilometres where the Turkwel River once flowed. Acacia trees, stripped of their leaves by desperate livestock, stand like sentinels over a landscape that has lost its capacity to sustain life. The carcasses of cattle, goats, and donkeys litter the roadside — grim markers of a drought that has erased years of painstaking pastoral wealth accumulation.

Kenya is in the grip of its most severe drought in four decades. Five consecutive rainy seasons have failed or underperformed since March 2023, a meteorological anomaly that climate scientists attribute to the La Nina weather pattern amplified by broader climate change trends. The result is a humanitarian crisis of staggering proportions: approximately 4.5 million people are facing acute food insecurity, 1.2 million children under five are acutely malnourished, and over 600,000 pregnant and breastfeeding women require emergency nutrition support.

The crisis, while concentrated in Kenya's 23 arid and semi-arid counties, has ripple effects across the national economy, affecting food prices, power generation, urban water supply, and the tourism sector that accounts for approximately 10 percent of GDP.

The Scale of Devastation

The Kenya Food Security Steering Group's March 2026 assessment paints a bleak picture. Across the Arid and Semi-Arid Lands, which cover approximately 80 percent of Kenya's landmass and are home to approximately 16 million people, crop production has declined by an average of 65 percent compared to the five-year average. Pasture availability has declined by over 70 percent, and water sources — including boreholes, pans, and seasonal rivers — have dried up at unprecedented rates.

The livestock sector, the primary livelihood in ASAL counties, has been devastated. An estimated 3.2 million head of cattle, 6.5 million goats and sheep, and 500,000 camels have died since the onset of the drought, representing a loss of approximately $2.1 billion in pastoralist assets. In Turkana and Marsabit counties, where livestock accounts for up to 90 percent of household wealth, the loss of animals has pushed thousands of families below the poverty line virtually overnight.

"The drought has destroyed everything we built over generations," said Joseph Ekiru, a 58-year-old pastoralist from Loima sub-county in Turkana, speaking at a relief distribution centre run by the Kenya Red Cross. "I had 200 cattle before the drought. Now I have 12. My children have stopped going to school because we cannot afford fees. We are surviving on food aid. This is not a drought — it is a catastrophe."

The situation is equally dire for agro-pastoralist communities in counties such as Makueni, Kitui, and Garissa, where rain-fed agriculture is the primary livelihood. Maize, beans, and sorghum harvests have failed for five consecutive seasons, forcing families to rely on market purchases for food. With food prices inflated by the supply shortage — maize flour prices have increased by 85 percent since early 2024 — many households are unable to afford even basic staples.

The Malnutrition Crisis

The drought's most alarming consequence is its impact on child nutrition. The Kenya Nutrition Survey, conducted in February 2026 by the Ministry of Health and UNICEF, found that the prevalence of acute malnutrition among children under five in the most affected counties had reached 28.4 percent — well above the World Health Organization's emergency threshold of 15 percent.

Global acute malnutrition rates are highest in Mandera (32.1 percent), Turkana (29.8 percent), and Wajir (27.5 percent), where health facilities report a significant increase in admissions for severe acute malnutrition with medical complications. Therapeutic feeding programmes, run by UNICEF, the World Food Programme, and non-governmental organisations, are operating at capacity but are constrained by funding shortfalls.

"The nutritional situation is critical and deteriorating," said Dr. Patrick Amoth, Kenya's Director General for Health. "We are seeing children arriving at health facilities in conditions that would have been unthinkable even five years ago. If the rains fail again, we risk a full-scale famine."

Maternal and child health services have been disrupted by the drought, as health facilities in ASAL counties struggle to maintain operations without reliable water and electricity. The closure of approximately 45 health facilities in Turkana and Marsabit due to water shortages has left an estimated 180,000 people without access to primary healthcare.

Water and Energy Impacts

The drought has affected water supply and energy generation far beyond the ASAL counties. Nairobi's main water sources — the Ndakaini Dam and the Sasumua Dam — are at critically low levels, with the Nairobi City Water and Sewerage Company imposing rationing that limits supply to alternate days in some neighbourhoods.

The Kenya Electricity Generating Company has reported a 35 percent reduction in hydroelectric power output due to low water levels at the Seven Forks dams on the Tana River. The shortfall has been partially offset by increased geothermal and wind generation, but the result has been a 15 percent increase in the fuel cost surcharge on electricity bills, adding to the financial pressure on households and businesses.

Urban water shortages have sparked conflicts in Nairobi's informal settlements, where residents queue for hours at communal water points. In Kibera, Nairobi's largest informal settlement, residents report paying up to 10 shillings per 20-litre jerrycan of water from private vendors — five times the normal price.

The Climate Science

Climate scientists at the Kenya Meteorological Department and the IGAD Climate Prediction and Applications Centre have linked the drought to the combination of La Nina conditions in the Pacific Ocean and broader warming trends in the Indian Ocean. The region has experienced below-average rainfall in 20 of the past 25 rainy seasons, a pattern consistent with projections from the Intergovernmental Panel on Climate Change.

"Climate change is not a future threat for Kenya — it is a present reality," said Dr. John Mwangi, a climate scientist at the University of Nairobi. "The frequency and severity of droughts are increasing, and the coping mechanisms that communities have relied on for generations are no longer sufficient."

The March-to-May 2026 long rains season, which typically accounts for 70 percent of annual rainfall in most parts of the country, is forecast to be below average for the sixth consecutive season, according to the Kenya Meteorological Department's seasonal outlook. If the forecast holds, the humanitarian crisis will deepen significantly.

Government and Humanitarian Response

The Kenyan government has allocated approximately 12 billion shillings to drought response in the current fiscal year, supplemented by approximately 8 billion shillings from development partners. The National Drought Management Authority is coordinating relief operations across 23 counties, distributing food, water trucking services, and livestock feed supplements.

The World Food Programme, which is providing food assistance to approximately 1.8 million people in Kenya, has warned that its operations are underfunded and may need to scale back if additional resources are not mobilised. The organisation's Kenya country programme has a funding gap of approximately $180 million for 2026.

International donors, including the United States, the European Union, the United Kingdom, and Japan, have collectively contributed approximately $340 million to Kenya's drought response since the onset of the current crisis. However, humanitarian agencies warn that the scale of need continues to outpace the availability of resources.

Adaptation and Long-Term Resilience

The drought has intensified the conversation about climate adaptation in Kenya. The National Climate Change Action Plan, updated in 2025, prioritises investments in water harvesting, drought-resistant crop varieties, early warning systems, and the restoration of degraded ecosystems.

The government's programme to develop 100 large-scale water pans in ASAL counties has delivered 32 pans to date, with a combined storage capacity of approximately 4.8 million cubic metres. While insufficient to address the scale of the crisis, these investments represent a shift from emergency response to long-term resilience building.

Community-based adaptation programmes, supported by organisations such as the International Fund for Agricultural Development and the Green Climate Fund, are helping pastoralist communities diversify their livelihoods through activities such as beekeeping, poultry farming, and small-scale irrigation. In Isiolo County, a programme supported by the Adaptation Fund has introduced drought-tolerant sorghum and millet varieties to 5,000 households, increasing food production despite the water scarcity.

A Future Under Threat

Kenya's drought crisis is a stark reminder that climate change is not an abstract global challenge but an immediate threat to the lives and livelihoods of millions of Africans. The country's vulnerability is rooted in structural factors — dependence on rain-fed agriculture, limited water storage infrastructure, and the concentration of poverty in climate-sensitive regions — that require sustained investment and policy attention.

The crisis also underscores the global injustice of climate change: Kenya, which contributes approximately 0.1 percent of global greenhouse gas emissions, is bearing a disproportionate share of its consequences. At the most recent COP summit, Kenyan President William Ruto — who also served as chair of the African Group of Negotiators — called for increased climate finance flows to developing countries, arguing that "the countries that did the least to cause this crisis are suffering the most from its effects."

For the pastoralists of Turkana, the farmers of Makueni, and the families queuing for water in Kibera, the climate crisis is not a policy debate. It is a daily struggle for survival, one that will continue long after the headlines fade.
