How Ujuzi Kilimo Is Transforming African Agriculture with Data
In a continent that holds 60% of the world’s remaining arable land, the future of global food security may rest squarely on Africa’s shoulders. Yet, millions of smallholder farmers across the continent continue to farm by guesswork, guided more by tradition and intuition than informed decision-making. Brian Bosire, founder and CEO of Ujuzi Kilimo, is on a mission to change that.
For our 183rd episode, Terser Adamu was joined on the Unlocking Africa Podcast by Brian Bosire, CEO and Co-Founder of UjuziKilimo, a leading agri-tech company empowering Africa’s smallholder farmers through data science, IoT, and predictive analytics.
Farming Meets Data Science
Growing up in rural Kenya, Brian witnessed the hardships his farming parents faced each season, low yields, failed harvests, and mounting frustration. Despite their dedication, their farming decisions were not informed by data, but by what neighbors were doing or what had "always been done." This sparked Brian’s vision: to empower African farmers with digital tools and actionable insights to manage their soil and crops more scientifically.
With a background in electronics engineering and a passion for solving local problems, Brian co-founded Ujuzi Kilimo, a precision agriculture company that uses AI, machine learning, and IoT to improve soil health and crop productivity.
Bringing the Lab to the Farm
One of Ujuzi Kilimo’s flagship innovations is the SoilPal, a portable, internet-connected soil sensor device that captures critical data on soil nutrients, acidity, salinity, and more. Instead of the traditional model where farmers send samples to labs in urban areas and wait weeks for results, SoilPal allows farmers to receive personalised, actionable recommendations on-site within minutes.
This data is analysed via FarmSuite, Ujuzi Kilimo’s analytics platform that overlays soil data with weather, crop types, and historical insights to generate tailored agronomic advice. The system even provides alternative fertiliser options based on what’s affordable and available locally.
Empowering Farmers at Scale
Since its inception, Ujuzi Kilimo has supported over 100,000 farmers, and has set an ambitious target of reaching 1 million farmers in the next five years. Their scalable model combines B2B and B2B2C strategies: working with agricultural organisations and field agents who deliver soil testing services directly to farmers, often for just $3 to $5 per test.
Through partnerships with governments, research institutions, and tech giants like Google, Ujuzi Kilimo has been able to digitise massive datasets and develop predictive models that inform not just farmers, but also policymakers and financial institutions.
“We want to be the go-to intelligence layer for African agriculture,” says Brian. “Whether it's a farmer choosing crops, a bank issuing agri-loans, or a government designing a food policy, they should rely on insights powered by Ujuzi Kilimo.”
Overcoming Barriers to Growth
Despite the progress, challenges remain. Capital constraints, infrastructure limitations, and fragmented distribution networks pose real obstacles to scaling. But with strong partnerships and a tech platform that can be deployed in multiple regions remotely, Brian is optimistic about expanding Ujuzi Kilimo’s reach across the continent.
Rewriting the Farmer’s Narrative
One surprising insight Brian shared is how many farmers overuse fertiliser, believing that “more is better.” But data reveals that precision, not quantity, leads to better yields and healthier soil. What’s more, Brian has learned to value the local knowledge and experience of farmers, incorporating their feedback into the platform to complement the scientific data.
As Africa faces growing climate pressures, the need for data-led, adaptive agriculture is more urgent than ever. Brian envisions a future where every farmer has access to a digital dashboard that informs their decisions, from crop choice to market strategy.
“Data will drive everything,” he says. “It will be the default.”
Final Thoughts: Africa Can’t Outsource Its Future
Closing the conversation, Brian shared a powerful mantra:
“You can't outsource your life. You can't outsource your dreams or aspirations or hardships.”
It’s a fitting reminder that Africa’s food security, economic prosperity, and agricultural transformation must be built from within, by Africans, for Africans, using tools that combine indigenous wisdom with cutting-edge technology.
