As South Africa faces mounting pressure from climate change, water scarcity and rapid urbanisation, the future of farming may not lie in fields. It may instead be growing inside a shipping container.
Western Cape-based agri-tech start-up Arable Grow is pioneering a new model of urban agriculture that combines locally developed technology, hydroponics and renewable energy to grow fresh, nutrient-dense produce in climate-controlled shipping containers. By producing food closer to where people live, the business is reimagining traditional farming while helping build a more resilient and sustainable food system.
Unlike conventional farming, which depends on seasonal conditions, large tracts of land and lengthy transport routes, Arable Grow’s modular farms can be established close to consumers, producing consistent, high-quality crops throughout the year.
Designed specifically for African conditions, the container farms use approximately 95% less water than conventional farming, eliminate the need for pesticides and significantly reduce transport distances and food waste. Produce is harvested and delivered to retailers within hours, preserving freshness, flavour and nutritional value while lowering the environmental impact associated with traditional supply chains.
For founder and CEO Hein Duvenhage, the vision has always extended far beyond growing vegetables.
“The big idea was to build a business that makes a difference and use innovation and technology to develop a solution designed specifically for Africa,” says Duvenhage. “We’re trying to solve a high nutritional density problem in urban environments while building a farming model that is more sustainable, more efficient and better suited to the future.”
The technology behind Arable Grow has largely been developed in-house rather than imported, enabling the business to adapt its systems to South African realities. Solar integration, water-retention systems and resilience against load shedding ensure reliable production while reducing dependence on scarce natural resources.
The company’s commitment to sustainability also extends beyond cultivation. Crops are grown according to demand to minimise waste, while any surplus produce is dehydrated and transformed into nutrient-rich superfood powder, extending its shelf life and creating additional value. The company also partners with Beaumont Primary School in Somerset West, introducing learners to urban farming and inspiring future generations to think differently about agriculture.
While innovation is central to Arable Grow’s success, bringing an entirely new farming model to market presented a different challenge.
For many entrepreneurs, developing breakthrough technology is only part of the journey. Gaining market access, achieving rigorous food safety standards and building retailer confidence can often prove even more difficult than developing the product itself. That is where SPAR became an important partner.
As Arable Grow’s first retail partner, SPAR recognised the potential of a locally developed innovation that aligned with its commitment to supporting entrepreneurship while building stronger, more resilient local supply chains. Through SPAR’s Supplier Development Programme, the business received practical guidance to achieve Good Agricultural Practice (GAP) certification, strengthen its operational capabilities and successfully enter the formal retail market.
“Our product offering is unique, and because it’s something new, people don’t always understand it immediately,” says Duvenhage. “The partnership with SPAR has given us exactly the kind of backing a start-up needs. Beyond helping us through certification, SPAR’s endorsement has given us credibility and opened doors that would otherwise have taken years to unlock.”
For SPAR, supplier development is about more than creating new suppliers. It is about investing in South African entrepreneurs who are developing innovative solutions that strengthen local industries, create jobs and deliver long-term value for communities.
“At SPAR, we believe the future of South Africa’s food system depends on supporting local innovation and creating opportunities for entrepreneurs to grow alongside us,” says Yolisha Govender, Group Supplier Development Specialist at SPAR.
“Our Supplier Development Programme is designed to equip emerging businesses with the tools, knowledge and market access they need to build sustainable enterprises. Businesses like Arable Grow demonstrate how South African innovation can help address some of our country’s most pressing challenges, from food security and sustainability to building resilient local supply chains.”
Today, Arable Grow supplies SPAR retailers in the Western Cape, but its ambitions stretch far beyond one region. Rather than building large, centralised facilities, the company envisions modular container farms operating in cities and towns across South Africa, producing fresh food closer to consumers while reducing pressure on traditional agricultural systems.
“We want to demonstrate that vertical farming isn’t just possible in South Africa, it’s scalable,” says Duvenhage. “If we can establish container farms in communities across the country using technology designed for Africa, we believe we can play a meaningful role in strengthening food security while creating a more sustainable future.”
From a single container farm in Somerset West to a vision of decentralised food production across South Africa, Arable Grow is proving that innovation doesn’t always begin on vast commercial farms.
Sometimes, it begins inside a shipping container.
And with the right partnerships, those ideas can grow from local innovation into solutions that help shape the future of South African agriculture.
