SDG Challenge
Interdisciplinary innovators from the Faculty of Natural and Agricultural Sciences – Njabulo Dlamini, Vuyelwa Nkoi, Hanipher Mili, Gugulethu Nhlapho, and Almaré de Bruin – winners of the 2025 SDG Challenge South Africa.

A dynamic team of students from the University of the Free State (UFS) has secured first place in the 2025 SDG Challenge South Africa – a prestigious competition that unites students and industry partners in addressing real-world issues aligned with the United Nations Sustainable Development Goals (UNSDGs). This outstanding achievement celebrates the creativity, collaboration, and strong commitment of UFS students to building a more sustainable and inclusive future.

Hosted by Soapbox South Africa, the SDG Challenge pairs student teams with industry experts to co-design practical solutions to pressing societal needs. Competing against leading institutions – including the University of Pretoria, University of Zululand, University of Johannesburg, the University of the Witwatersrand, and the University of KwaZulu-Natal – the UFS students distinguished themselves with a community-driven, scalable approach.

The winning UFS team consisted of Almaré de Bruin, Njabulo Dlamini, and Vuyelwa Nkoi from the Department of Sustainable Food Systems and Development, as well as Hanipher Mili and Gugulethu Nhlapho from the Department of Agricultural Economics – reflecting a powerful interdisciplinary collaboration.

 

Innovative Agrihub solution for community sustainability

Partnering with Ivanplats mine, the students developed a holistic solution to reduce food insecurity and promote environmental sustainability in resource-limited communities in Mokopane.

Their innovative project, built around a WhatsApp-based Agrihub, enables agricultural knowledge sharing, market access, and community engagement. The solution included the following:

  • A WhatsApp Agrihub platform for real-time agricultural support
  • An Implementation Manual for community rollout
  • A low-cost irrigation prototype designed for small-scale gardens
  • A scalable model for replication in other communities
  • A final showcase presentation demonstrating its feasibility and long-term impact

To reduce surplus produce waste and create entrepreneurial opportunities, the team also produced value-added products – including pickled beetroot and carrot preserves – in the UFS food lab.

The Agrihub doubles as a community marketplace where residents can sell both fresh produce and recyclables. A R20 subscription fee supports local facilitators and content creators, promoting sustainability and community ownership.

Their project advances multiple UNSDGs, notably Zero Hunger, Responsible Consumption and Production, Climate Action, and Decent Work and Economic Growth.

“This victory is a testament to the calibre of our students and the mentorship they receive,” says Prof JW Swanepoel from the Department of Sustainable Food Systems and Development. “Their innovative thinking and commitment to real-world impact reflect the values of the University of the Free State.”

The UFS team’s success not only underscores their potential as emerging leaders in sustainability, but it also affirms the university’s growing role in driving development and resilience across African communities.

Innovation the focus of 28th Sophia Gray Memorial Lecture

Al Stratford, designer, inventor and architect, presented the 28th Sophia Gray Memorial Lecture on 25 August at the Reservoir at the Oliewenhuis Art Museum in Bloemfontein. The event, hosted by the Department of Architecture at the University of the Free State, was also the opening of an exhibition of Stratford’s work.

In his career of 40 years, Stratford has patented many products and won several awards in industrial design and architecture. He is known in South Africa for his development of innovative building technology such as the Winblok Precast Concrete Window System. In 2009 and 2010, he also served as president of the South African Institute of Architects.

The title of his lecture was: Reductive Innovation in Architecture. Throughout his career, Stratford endeavoured – through his designs and inventions – to apply the principle of “reduction” to the building material he used and technology he examined.

Stratford designs and builds smart buildings
Stratford says a home is the paradigm of self-expression. His career as architect started with the building of five houses in Gonubie, near East London. Everything he knew about architecture at that stage, he had taught himself by reading on the subject at the local library. Later on, he achieved great heights in his career by designing and building, among others, the Stratford Guesthouse; the sustainable and resourcefully designed campus buildings for the University of Fort Hare (an institutional building not utilising any electrical air-conditioning); the Edenvale Baptist Church; and a community hall.

His technology is widely used in the building industry

“The arrogance in me gets humiliated when I
see what other people and God has done.”


His technical drawing skills, acquired at an early age during his training as motor mechanic, are still practised years later, particularly in his inventions. Stratford is the inventor of technology commonly used in the building industry today. Of these, the Winblok window system which he patented in 1981, is one of his best known patents. The use of these windows is characteristic of many of the buildings he designed and built. Other technology he invented and patented, includes the Winstep stairs, the Windeck flooring system, and the StratFlex furniture technology.

Furniture designs win him awards
He likes to quote architect Ludwig Mies van der Rohe: “A chair is a very difficult object. A skyscraper is easier.” Stratford started designing and manufacturing his own furniture and never lost this passion. In 2013, he won the Innovation Award at the Design Indaba for his “flat pack” furniture technology.

The humble Stratford – designer, inventor, industrialist, and architect – says he is simply playing around with God’s creation. “The arrogance in me gets humiliated when I see what other people and God has done.”
