How Kenyan farmers are adapting to a hotter, drier future
Nairobi — On a sun-scorched morning in Makueni County, southeast Kenya, the soil tells a story of transformation. Where maize once withered under erratic rainfall, drought-resistant sorghum now flourishes. Solar-powered irrigation systems hum quietly between rows of vegetables, whilst farmers track soil moisture levels on their mobile phones. This is not a pilot project. It is the future of African agriculture, and it is already here.
Kenya faces a challenge that extends far beyond its borders. Climate change threatens to reduce agricultural productivity across critical regions, with only 16% of the country’s land receiving sufficient rainfall for reliable crop yields. With nearly two million Kenyans experiencing acute food insecurity as of early 2024, the stakes could not be higher. Yet Kenya is emerging as a continental leader in climate-smart agriculture, demonstrating that transformation is possible when policy ambition meets farmer-led innovation.
The hidden cost of climate adaptation
The numbers reveal a stark reality: African smallholder farmers are already financing their own climate resilience, spending billions annually with minimal external support. Recent analysis estimates that East African smallholders require $34.6 billion yearly to strengthen a sector supporting over 75% of regional employment. Current global spending reaching these farmers covers less than 1% of that need.
The adaptation gap is stark across the continent. West Africa requires $11.1 billion annually to protect nearly two million cocoa farmers whose output underpins Europe’s $50 billion chocolate industry. Southern Africa needs $13.2 billion yearly to avert drought-driven crop failures that left 21 million children malnourished in 2023-24. These figures underscore a fundamental imbalance: the world’s most vulnerable farmers shoulder the greatest adaptation burden whilst receiving the least support.
Kenya’s strategic response
Kenya’s approach offers a template for addressing this challenge. The Kenya Climate Smart Agriculture Strategy, running from 2017 to 2026, targets four critical areas: building resilience to temperature and rainfall changes, reducing greenhouse gas emissions from agriculture, establishing enabling policy frameworks, and addressing cross-cutting constraints in human capacity and finance.
Agriculture accounts for one-third of Kenya’s greenhouse gas emissions, which were estimated at 73 million tonnes of carbon dioxide equivalent in 2010 and are projected to reach 143 million tonnes by 2030 without mitigation. The sector’s predominantly rain-fed nature makes it acutely vulnerable to climate variability. Approximately 98% of agriculture in Kenya relies on rainfall, yet only 16% of the country’s land receives enough rain consistently for suitable crop yield.
The government’s response extends beyond agriculture. Kenya now produces 90% of its energy from renewable sources and requires $40 billion in investment over the next decade to meet its climate goals. The country hosted the inaugural Africa Climate Summit in 2023, positioning itself at the forefront of continental climate leadership.
Innovation at ground level
Practical innovations are reshaping Kenya’s agricultural landscape. The climate-resilient impact hub model takes an area-based approach that layers ecosystem restoration, water management solutions, and alternative livelihood options. The model promotes climate-smart agricultural practices, fosters market opportunities, and strengthens climate-adapted social protection programmes.
Technology plays a central role. Companies such as SunCulture provide solar-powered irrigation systems to smallholder farmers across Kenya, Côte d’Ivoire, Ethiopia, Togo, and Uganda, substantially reducing reliance on rainfall and stabilising yields. Digital soil mapping, satellite imagery, and machine learning enable farmers to make informed decisions about crop suitability and fertiliser application whilst reducing erosion.
Research shows that farmers adopting multiple adaptation strategies achieve substantially higher food security outcomes. Analysis found that farmers using one adaptation strategy experienced 7-11% higher food security status compared to non-adopters, whilst those implementing four strategies saw improvements of 14-18%.
The most widely adopted practices include planting drought-tolerant crop varieties (55% of farmers surveyed), growing diversified crops (34%), planting early maturing varieties (22%), and diversifying household income sources (18%). These adaptations require minimal external support but deliver measurable results.
The financing conundrum
Despite Kenya’s progress, systemic challenges persist. Less than 1% of Kenyan farmers have insurance coverage, limiting access to credit and discouraging investment in improved seeds, equipment, and technology. The government is now proposing regulations requiring insurers to settle weather-related claims within ten days under index-based insurance schemes, which pay out based on predetermined variables such as rainfall rather than individual assessments.
Climate finance architecture remains a critical bottleneck. Most adaptation funds flow through large international agencies, with minimal resources reaching farm level. Farmer organisations propose channelling money directly to cooperatives, with an initial target of $100 million in capital from donors, development banks, and African nations.
Policy and market integration
Kenya’s Agricultural Sector Transformation and Growth Strategy (2019-2029) integrates climate considerations throughout implementation, augmenting the sector’s resilience and productivity whilst contributing to emissions reduction targets. The Kenya Climate Smart Agriculture Project, supported by the World Bank from 2017 to 2022, promoted adoption of improved technologies, enhanced access to climate and market information, and supported project coordination at national and county levels.
County-level initiatives demonstrate the potential for localised action. Vihiga and Kisumu counties are establishing community seed banks and small-scale irrigation projects to boost agricultural value chains. Vihiga County funded a seed bank and processing plant in 2024, creating an official market for native seed varieties. Over 8,000 smallholder farmers in Kisumu now access certified seed sources.
Carbon markets present both opportunity and challenge. Kenya announced its commitment to scaling voluntary carbon markets at COP27 and amended its Climate Change Act to outline a framework for participation. However, strict carbon credit requirements, limited financial resources, and the need for robust governance frameworks constrain adoption. Experts emphasise the importance of policies prioritising non-carbon outcomes such as food security, nutrition, and economic development supported by carbon removals and reductions.
The human dimension
Climate-smart agriculture adoption rates remain low despite government promotion and development partner support. Research examining institutional factors among smallholder potato farmers in Nakuru County found that whilst the Kenya Climate Smart Agriculture Strategy guides agricultural transformation, implementation gaps persist.
Younger farmers and those with higher education levels show greater willingness to adopt climate-smart practices. Family size, land size, farm income, extension contact, training, and information access all positively influence the number of adaptation strategies farmers employ. Peer interactions, particularly with fellow farmers and neighbouring community members, emerge as vital information sources. Radio broadcasts remain the primary avenue for accessing climate change information across survey regions.
Gender dynamics shape resilience capacity and the potential to benefit from agricultural interventions. Women constitute over 50% of the agricultural labour force in sub-Saharan Africa, yet face systemic barriers to accessing resources, finance, and markets. Climate change intensifies far faster in Africa than anywhere globally, and farmers bear the greatest impact despite contributing minimally to global emissions.
Regional and continental implications
Kenya’s experience offers instructive lessons for climate-vulnerable nations across Africa. The continent accounts for just 3.8% of global greenhouse gas emissions yet faces the greatest exposure to climate impacts. If current climate trajectories persist, crop production across East Africa will decline by 18% by 2050, placing some 200 million people at risk of extreme hunger.
Climate-smart agriculture has emerged as a comprehensive strategy addressing interconnected challenges facing smallholder farmers, focusing on three core goals: increasing agricultural productivity, adapting and building resilience to climate change, and reducing greenhouse gas emissions from agriculture. Evidence from Ethiopia shows that adopting improved seed varieties and compost enhances adaptation, ensures greenhouse gas mitigation, and promotes food security.
The Alliance for a Green Revolution in Africa emphasises that Africa’s food systems require transformation pathways that enable smallholder farmers to increase resilience to climate shocks. The organisation recognises that food security alone is insufficient—food must meet nutritional needs.
The path ahead
Building a climate-resilient food system in Kenya and across Africa requires action across five dimensions.
Direct farmer financing — Adaptation finance must reach smallholder farmers directly rather than filtering through large international agencies. Proposed mechanisms represent one path for achieving this, supporting hands-on initiatives including irrigation systems, seed repositories, community insurance schemes, and soil rehabilitation projects.
Technology transfer and scaling — Proven innovations such as solar irrigation, drought-resistant varieties, and digital soil mapping must move from pilot to scale. This requires investment in infrastructure, training, and support systems that enable widespread adoption.
Policy coherence — Climate, agricultural, water, and energy policies must align at national and county levels. Kenya’s National Climate Change Council demonstrates how interministerial coordination fosters cohesive action by integrating efforts across sectors.
Market systems development — Climate-smart practices generate limited impact without market access. Value chain development, quality standards, and trade facilitation enable farmers to capture returns from investment in resilience.
Knowledge systems and extension — Farmers rely primarily on radio and peer networks for climate information. Strengthening extension services, leveraging mobile technology, and supporting farmer-to-farmer learning amplifies adaptation capacity.
A continental imperative
COP30 concluded recently in Belém, Brazil, with 195 parties adopting the Belém Package, which includes agreements on just transition, adaptation finance, trade, gender, and technology. Over 122 countries submitted new or updated nationally determined contributions, a decisive step toward shaping a new climate economy. Yet the UN climate talks in Brazil ended with a pledge of more funding for countries to adapt to extreme weather, but did not include a roadmap for phasing out fossil fuels.
Kenya’s position as a regional food producer and climate leader places it at the intersection of vulnerability and opportunity. The country’s strategies, from climate-resilient impact hubs to index-based insurance reforms, provide a roadmap for transformation. Yet success hinges on bridging the adaptation financing gap and ensuring that policies translate to farm-level impact.
As the international community considers COP30’s outcomes, Africa’s farmer federations are demanding systemic change. The message is clear: climate resilience cannot be built on sympathy alone. It requires investment, policy reform, and genuine partnership with the farmers who feed the continent.
The question is not whether Africa can build climate-resilient food systems. Kenyan farmers are demonstrating daily that transformation is possible. The question is whether global finance and policy architectures will rise to match their ambition and investment, or whether Africa’s farmers will continue financing resilience alone.
