South Africa, one of the world’s driest nations, faces a looming challenge as the government considers stricter water usage controls, which could jeopardize food security. Michael Esmeraldo, managing director of Netafim South Africa, speaking at Agbiz’s media day in Stellenbosch, predicted that within five to ten years, certification bodies may rigorously audit water consumption, imposing caps such as 750–800 mm for citrus crops to enforce sustainability. With agriculture consuming 61% of the country’s water, Esmeraldo argues the sector must take greater responsibility to meet consumer demand for water-efficient products.
South Africa’s per capita water use stands at 223 liters per day, exceeding the global average of 173 liters, while water storage infrastructure has not kept pace with population growth and expanding irrigation needs. Inefficient flood irrigation, accounting for 14% of systems, should be eliminated, as center-pivot (33%) and drip irrigation (18%) are more efficient. Poor maintenance, like leaking pipes, is the primary cause of water loss, exacerbating the strain on resources. Esmeraldo proposes strict monitoring with penalties for wastage, subsidies for smallholder farmers adopting water-efficient technologies, and bank financing for sustainable systems.
While South African farmers are among the world’s best in irrigation, Esmeraldo warns that without proactive water conservation, the sector risks a crisis. The government’s push for sustainability is critical, but heavy-handed restrictions without adequate support could undermine agricultural output, threatening both local food supply and export markets. Balancing water conservation with food security will require careful policy design, robust subsidies, and investment in modern irrigation to ensure farmers can adapt without compromising the nation’s breadbasket.
Stakes are high. Agriculture isn’t just about feeding the nation; it’s an economic lifeline, with 20% of South Africa’s $13 billion in agricultural exports feeding EU markets. Droughts and erratic weather, worsened by climate change, already strain production. If smallholder farmers, who form the backbone of rural economies, are squeezed by water caps without affordable access to modern irrigation, the ripple effects could destabilize rural communities and urban food supply chains alike. The government’s push for sustainability must avoid heavy-handed policies that punish farmers rather than empower them.
The clock is ticking. South Africa cannot afford to wait for a crisis to act. Balancing water conservation with food security demands a proactive, inclusive approach—supporting farmers, not strangling them with regulations. If done right, the nation can safeguard its food supply, protect its export markets, and lead globally in sustainable agriculture. If not, the consequences could be dire for both the plate and the pocketbook.
