University Students Pitch Tech-Based Solutions to Support Small-Scale Farmers at TCS Sustainathon 2025

Strategic Insights -

South African university students competed in the 2025 Tata Consultancy Services (TCS) Sustainathon, showcasing practical, tech-based solutions to pressing social and environmental problems, such as sustainable agriculture and food security. The competition, now in its fourth year locally, challenges young people to design innovative solutions to tackle challenges like helping township farmers access affordable tools, fighting child malnutrition, and connecting small-scale growers directly with markets.

Key Takeaways:

  • The 2025 TCS Sustainathon received over 400 registrations from 50 universities, with 10 finalist teams presenting their solutions at the finale on 8 September 2025.
  • The top three winners received financial prizes, with the first-place team, PowerLock, receiving R30,000 for their project, AgriSentry, which provides small-scale farmers with affordable ways to monitor and understand their crops.
  • The AgriSentry system includes sensors to measure soil moisture, sunlight, and temperature, sending advice via SMS alerts and building a record of farm performance, crucial for accessing credit, subsidies, or crop insurance.
  • The team has already built and tested a prototype, set up a website for managing farmer data, and plans to start working directly with local farmers before refining the devices and expanding.
  • Second-place team Sustainorise developed Peu, a digital marketplace for farmers, connecting them with urban markets and cutting out middlemen to ensure fair trade.
  • Third-place team Agri-link created a system of smart sensor nodes and an "insight engine" to give smallholder farmers affordable access to precision agriculture, tracking soil moisture, temperature, and other micro-climate data.
  • The judges commended the teams for their clear storytelling, responsible AI practice, and adoption of existing technologies to deliver immediate functionality.

Statistics:

  • Over 400 registrations from 50 universities across South Africa
  • 10 finalists presented their solutions at the TCS Sustainathon 2025 finale on 8 September 2025
