Bridging the gap: Scaling Kenya's climate-smart agriculture from programme to system
Community members construct a sand dam in Senatwo, West Pokot County. Kenya must move beyond isolated water pans and invest in sustainable infrastructure such as sand dams and solar-powered irrigation cluster.
What you need to know:
Agriculture anchors the economy, contributing a third of GDP and employing most of the rural workforce, yet it remains heartbreakingly exposed. Over 80 per cent of cropland is left to the mercy of unpredictable rains.
Kenya’s relationship with climate-smart agriculture is a story of sharp contrasts, where brilliant ingenuity coexists with systematic vulnerability. On one hand, the country is a cradle of innovation; on the other, it faces escalating climate threats and policy gaps that fragment progress.
This tension is far from abstract. Agriculture anchors the economy, contributing a third of GDP and employing most of the rural workforce, yet it remains heartbreakingly exposed. Over 80 per cent of cropland is left to the mercy of unpredictable rains.
In response, Kenyans have built a layered resilience, a blend of high-tech solutions like drought-tolerant seeds and grassroots adaptations such as ndiva water pans and clay-pot coolers.
But here’s the catch: these innovations are operating within a system that isn’t built to scale them. That 80 per cent rain-fed figure isn’t just a climate risk, it’s a policy and governance gap. Kenya lacks a coherent, implementable national strategy for water management, small-scale irrigation, and watershed protection, a gap made wider by the frequent disconnect between national policy and county-level execution. Meanwhile, climate models forecast more frequent droughts, putting millions of smallholder farmers, who produce most of our food, in constant peril.
For them, the so-called “climate-smart” toolkit is often out of reach. Why? Because less than five per cent of commercial lending reaches agriculture. Public mechanisms to de-risk loans, promote inclusive insurance, or blend finance are still inadequate, and county governments often lack the technical and financial capacity to catalyse local agricultural finance.
We’re also wrestling with legacy policies that inadvertently trap farmers in fragile systems. Take maize monoculture, which covers 40 per cent of cropland. Input subsidies often prioritise hybrid seeds and synthetic fertilisers without parallel incentives for diversification or soil health, a paradigm that is often reinforced, not transformed, at the county level. The result? Debt cycles for farmers, and acidification degrading nearly a third of our arable land.
The sad bit is that climate change multiplies these threats. It accelerates the spread of pests and diseases, like Fall Armyworm, which has caused millions in losses, or livestock diseases that surge during drought-induced migrations. Our biosecurity frameworks, unfortunately, remain reactive and under-resourced, struggling to keep pace, with county surveillance and response systems critically uneven.
So, how do we move from scattered programmes to a resilient system? It demands intentional policy and governance shifts in a few key areas, with county governments as pivotal implementation and innovation partners.
First, achieve water sovereignty in our drylands through decentralised governance. We must move beyond isolated water pans. Imagine a nationally backed, county-led “Water for Productive ASALs” programme, combining catalytic public investment in sustainable infrastructure such as sand dams and solar-powered irrigation clusters with devolved community-led governance, county-protected grazing corridors, and integrated county water master plans.
Second, ensure finance actually reaches smallholders, facilitated by counties. Establish a National Agriculture Financial Inclusion Facility to de-risk lending, but pair it with County Agri-Finance Windows that provide matching grants, aggregate local farmer groups for creditworthiness, and leverage county structures to scale bundled products like drought-tolerant seeds paired with micro-insurance. Digital platforms, promoted through county extension services, can unlock pay-as-you-go irrigation and improve credit scoring.
Third, adopt policies that incentivise regeneration at all levels. Reform national subsidies into “smart subsidies” that reward intercropping, legume integration, and soil care, and empower counties to design complementary input programs aligned with local agro-ecologies. Introduce a Soil Health Tax Credit. Let devolved public procurement for schools and county institutions prioritise diverse, local crops like sorghum and millet.
Fourth, integrate climate and biosecurity with county frontline capacity. Build a digital early-warning and rapid-response network for pests and diseases, with county agriculture officers as its core nodes. Speed up registration of biocontrol agents and invest in climate-resilient seed and vaccine research, with counties as key partners in dissemination and last-mile delivery.
Fifth, tackle post-harvest losses head-on as a shared national-county priority. Make this a joint infrastructure commitment with targeted grants for county-integrated aggregation centres, solar-powered cold storage at market hubs, and county-wide extension on proven low-tech solutions like hermetic bags.
Kenya’s greatest untapped asset is its arid and semi-arid lands: over 80 per cent of our territory. Transforming this frontier hinges on the policy and governance trifecta of water, finance, and regenerative practices. The potential is staggering: sustainable irrigation on just 10 per cent of suitable ASAL land could add over Sh200 billion annually to farm GDP, a prize that can only be unlocked through effective national-county collaboration.
Ultimately, the lesson is clear: technology is a tool, not a strategy. Real resilience will be built by policy and governance choices that scale what works and dismantle what holds us back. That means closing the adaptation financing gap, breaking down market barriers, empowering county governments as engines of local adaptation, and embedding climate action into every aspect of agricultural planning; from national to ward level.
The goal is a coherent, multi-level system that is not only ecologically robust, but socially equitable, where resilience means stable incomes, sustained peace, and opportunity for all who grow our food.
