Ugandan Engineer Turns Family's Rotten Tomatoes Into Award

Every morning before school, Shifra Ainomugisha had the same heartbreaking task: pulling rotten tomatoes from her family's storage while the fresh ones went to market.

Growing up in Uganda's Ibanda District, she watched her farming family work hard yet stay poor because so much of their harvest spoiled before it could be sold. The pattern became impossible to ignore when she couldn't afford basic school supplies despite everyone's labor.

"We were kept in poverty, yet we were laboring a lot," Ainomugisha remembered. That recognition at age 15 planted a seed that would eventually bloom into Solafam Uganda Limited.

At Makerere University in Kampala, she studied renewable energy engineering and met other farmers' children who understood the same struggles. Together with classmate Moreen Nabahiirwa, she had the knowledge to solve the problem but no money to start.

A lecturer who believed in their vision connected them to the Sahara Impact Fund. With that support, they built their first solar-powered cold room from a repurposed shipping container, locally sourced batteries, and solar panels.

Ainomugisha installed the prototype at her father's home. He became the first farmer to test whether it actually worked.

The results spoke clearly: tomatoes that normally lasted only days stayed fresh for 21 days in the cold storage. Her father could now wait out the harvest glut and sell when prices improved.

But convincing other farmers proved harder. "They saw a very young girl, 23 or 24 years old," she said, facing skepticism about a woman engineer solving their problems.

Trust grew slowly as neighbors watched her father's success. Solafam expanded beyond storage when farmers revealed that spoilage was just one piece of a bigger puzzle.

The Ripple Effect

Today, Solafam offers shared solar irrigation systems and LYN, an AI advisor farmers access through WhatsApp for help with pests, crops, and timing. Nearly 2,000 farmers already use the service.

One mother recently invited Ainomugisha to her daughter's university graduation. The woman's older children had never been able to afford higher education, but after using Solafam's services, she could finally support one child through college.

In June 2026, Ainomugisha received the Commonwealth Young Person of the Year award. She calls it "life-changing" for opening doors that were previously locked, including finally getting meetings with Uganda's government.

The young woman who once sorted rotten tomatoes now spends her days in the fields checking on irrigation systems and helping farmers across Uganda, with plans to expand to Tanzania and Kenya.
