On Tuesday morning in Johannesburg’s Soweto township, students at Mohloli Secondary School checked the water quality in new aquaponic tanks installed as part of a government-backed pilot. With winter’s chill pushing up vegetable prices at local markets, this hands-on approach to sustainable agriculture is drawing renewed interest among young South Africans and educators.
The Department of Basic Education reported this week that over 120 public schools in Gauteng and Western Cape now host aquaponics systems, up from fewer than 40 in early 2026. The initiative aims to bolster food security in urban areas, where climate shocks and supply disruptions have pushed monthly household food costs up by 14% since January. Students cultivate tilapia and leafy greens in closed-loop systems, providing produce for school feeding schemes and local families.
South Africa’s National Food Security Programme, expanded in March 2026, allocated ZAR 75 million (around $4 million) to school-based sustainable agriculture projects for the current fiscal year. Programme director Phumzile Maseko said Tuesday that the government is tracking yields and student engagement as key indicators, with a target to reach 200 schools by December 2026. “We’re moving from pilot to scale-up, but we need rigorous monitoring to avoid greenwashing,” Maseko told SDG Talking.
While aquaponics projects have proliferated in response to climate adaptation needs, critics warn that some installations lack technical support and long-term funding. Researchers at the University of Pretoria noted last week that only 68% of surveyed systems were fully operational after six months, citing maintenance gaps and water quality challenges. Government partners say they are addressing these issues with new teacher training programs rolling out later this month.
With youth unemployment at 45% in urban centers, South African NGOs see these projects as more than a food solution. “Aquaponics is also a skills pipeline,” said Nathi Sibanda, project manager at FoodForward SA, during a Wednesday workshop in Durban. “But success depends on sustained investment and honest reporting—not just ribbon-cuttings.”
