When Kennedy Kabue lost an entire greenhouse full of peppers to a crop disease, it felt like the end of the road.
Instead, it became the beginning of an ambitious journey—one that would lead him to create FarmSawa, a groundbreaking platform that uses Artificial Intelligence (AI) to deliver real-time agronomic advice to farmers across Kenya.
What started as a painful farming experience in Thika, Kiambu County, has now evolved into one of Kenya’s most accessible and promising agri-tech innovations.
Kennedy’s journey in agriculture began in childhood, growing up on the family’s farm in Thika. Farming was not a new concept to him. But the idea of blending it with technology was something he had never imagined—until disaster struck.
“Two years ago, we invested in a greenhouse and started growing hohos (bell peppers),” Kennedy recalls.
“But we lost the entire crop. After doing a root cause analysis, we discovered it was a disease we had failed to detect in time. That loss really hurt.”
At first, Kennedy did what most farmers do: he tried to find better ways to prevent such losses in the future. Then a friend in the tech world challenged him with a suggestion: why not try using AI to diagnose crop diseases?
“I was sceptical at first,” he says. “I thought, how can technology possibly diagnose what’s happening on a farm?”
But curiosity soon turned into experimentation—and then into a solution.
Kennedy and his team, which includes IT specialists and agronomists, began training an AI model to recognise plant diseases from images. They collected thousands of photos of diseased crops, tagged and labelled them, and created a library that the AI system could learn from.
The result was a WhatsApp-based chatbot that could receive a photo from a farmer, analyse it, and provide feedback in seconds.
“It’s very simple,” Kennedy explains. “A farmer notices a problem, takes a picture of the affected leaf, and sends it to our WhatsApp bot. Within about five seconds, the system analyses the image, identifies the disease, and suggests the next steps.”
The AI also provides advice on prevention, weather forecasts, and current market prices, offering a holistic service that’s tailored to the realities of small-scale farming.
And it’s all available on WhatsApp, a platform already widely used by farmers.
The success of FarmSawa is as much about timing as it is about technology. Across Kenya, the ratio of extension officers to farmers is estimated at 1:1,500 to as high as 1:5,000, far from the FAO’s recommended 1:400.
Many of the available officers lack resources such as transport and fuel, making it difficult to reach farmers in time.
As a result, thousands of farmers go without expert guidance, especially when it matters most—during pest outbreaks or changing weather patterns.
“Farmers are constantly making critical decisions based on limited information,” Kennedy notes. “That’s risky. One wrong move can cost you an entire season.”
By using AI to bridge this gap, FarmSawa is offering farmers an affordable, scalable solution that works even in the most remote areas, as long as they have a smartphone and internet connection.
While disease diagnosis is the standout feature, FarmSawa does much more. The system gives agronomic advice tailored to each crop and region, weather updates to help with planting and spraying decisions, and daily market prices for key commodities in markets such as Marikiti and Kirinyaga.
“This helps farmers plan their planting and marketing better,” Kennedy says. “They can avoid overproduction, and they’re no longer at the mercy of brokers.”
The platform is also in the process of integrating voice responses in Kiswahili to help farmers who may have difficulties reading or typing.
Kennedy’s innovation is part of a global wave of agri-tech solutions leveraging AI, Big Data, and mobile technology to solve age-old problems in agriculture.
In India, for example, AI is being used to predict pest outbreaks based on weather patterns. In the United States, robots are now sorting vegetables and even milking cows.
In sub-Saharan Africa, the potential for AI is enormous, particularly for smallholder farmers who make up over 70 per cent of the region’s food producers.
Here in Kenya, platforms like FarmSawa prove that AI doesn’t have to be expensive or complicated to work. By focusing on accessibility—through a familiar platform like WhatsApp—Kennedy and his team are creating solutions that meet farmers where they are.
“Technology should not replace the farmer,” he emphasises. “It should work for the farmer.”
Kennedy believes that one of the biggest impacts of FarmSawa will be in attracting young people to farming. Many youth view agriculture as outdated or unprofitable, but technology can change that.
“When young people see that farming can be smart, data-driven, and profitable, they start to see opportunity,” he says.
“Our goal is to make farming not just viable, but exciting again.”
And he’s already seeing signs of that change. More farmers are engaging with the bot, asking detailed questions, and providing feedback that helps improve the platform further.
Kennedy’s team is now expanding their services to include input recommendations, financial access, and eventually market linkages. They are also working with agrochemical companies and government agencies to provide verified, updated treatment solutions for various diseases.
“We started with the problem of diagnosis,” he says. “But now we’re looking at the entire farming journey—from seed to market.”
The platform also plans to make its data available to researchers and policymakers, helping improve food systems and inform interventions at a national scale.
For Kennedy, FarmSawa is more than a business—it’s a response to a personal loss and a passion to make farming better for everyone.
“I’ve been a farmer. I know what it feels like to watch your crops die and not know what to do. That’s why I built this—not from theory, but from experience.”
