Mulanje, Malawi — The wreckage left by Cyclone Freddy in 2023 was a stark reminder of climate change’s brutal toll on Africa’s most vulnerable. For Alex Maere, a 59-year-old small-scale farmer in the foothills of Mount Mulanje, it was a cataclysm. A healthy 850 kilograms (1,870 pounds) of corn, the annual foundation for his family of five, was reduced to just 8 kilograms. The fertile soil that had sustained his farm for decades was gone, washed away by relentless floods, leaving behind a barren landscape of sand and rock.
But for Maere, this disaster was also a catalyst for an embrace of an improbable solution: artificial intelligence. He is now part of a pilot project that has armed thousands of Malawian farmers with a generative AI chatbot, a tool designed to offer critical agricultural advice in a nation where survival often hinges on the success of a single harvest.
Developed by the non-profit Opportunity International and backed by the Malawian government, the AI-powered app, Ulangizi (meaning “advisor” in the local Chichewa language), is a strategic response to the nation’s intensifying food crisis. More than 80% of Malawi’s 21 million people depend on agriculture, and with successive climate shocks—including Cyclone Freddy and a recent El Niño-induced drought—the country’s food security has become a central issue ahead of next week’s national elections.
The chatbot’s impact has been immediate and, for Maere, transformative. After his soil was ruined, the AI suggested a novel adaptation: growing potatoes alongside his traditional corn and cassava. Following the guidance precisely, Maere cultivated a crop of potatoes that yielded over $800 in sales. “I managed to pay for their school fees without worries,” he said, beaming.
This small-scale success story underscores a growing trend across sub-Saharan Africa. While much of the global conversation around AI focuses on its role in Silicon Valley or on Wall Street, its most critical applications may be on the continent’s farms. With 33-50 million smallholder farms producing up to 80% of the food supply, according to the U.N., improving agricultural output is a matter of life and death. The World Bank reports that private investment in agriculture-related technology in the region surged from $10 million in 2014 to $600 million in 2022.
Yet, the path to technological adoption is fraught with uniquely African challenges. The continent’s linguistic diversity—hundreds of languages for AI tools to learn—is a significant barrier. Moreover, low literacy rates, a scarcity of smartphones, and a digital infrastructure that is at best patchy and at worst non-existent in rural areas, complicate a seamless rollout.
Ulangizi attempts to navigate these hurdles with a human-centric design. The WhatsApp-based app operates in both Chichewa and English, accepting both text and voice commands. Users can even snap a photo of a diseased crop and receive a diagnosis and treatment plan.
Crucially, the technology is delivered by a “human in the loop.” For Maere’s community, that person is Patrick Napanja, a 33-year-old farmer support agent equipped with a smartphone and the app. Napanja serves as a digital conduit, bridging the gap for farmers who lack devices or connectivity. He acknowledged the persistent obstacles: “Sometimes, most of an hour-long meeting is taken up waiting for responses to load because of the area’s poor connectivity.”
The fragility of this trust-based system is paramount. For a Malawian farmer on the brink of poverty, a single misstep or an AI “hallucination”—such as a misidentified crop disease—could be devastating. Daniel Mvalo, a Malawian technology specialist, warns that “if it fails even once, many farmers may never try it again.”
To mitigate this risk, the Malawian government has ensured Ulangizi’s programming aligns with official agricultural ministry advice. Webster Jassi, an official at the ministry, noted that while scaling remains a challenge, the potential for community-based knowledge sharing is immense. “Farmers who have access to the app are helping fellow farmers,” he said, leveraging technology to amplify traditional forms of collaboration and, in doing so, cultivating not just crops, but a more resilient future.
