How improving water supply could reduce inflation in South Africa, drought and water shortages are devastating parts of South Africa, costing the nation’s farmers up to R10 billion every year. The worst-affected provinces are KwaZulu-Natal, the Free State, Limpopo, the Northwest, and the Northern Cape. Here, farmers growing white maize, yellow maize, soybeans, and sunflowers have suffered major losses.
Compounding this issue, the war in Ukraine has driven up prices for basic needs like sunflower oil, crude oil, fertilizer, and wheat across African economies. South Africa doesn’t produce enough vegetable oil to meet local demand, sourcing the rest from Europe. Annually, the country produces only 800,000 metric tons of oil while importing 950,000 metric tons.
Could improve water security help lower the cost of living by localizing resources? Let’s look at sunflower oil.
The Challenge of Sunflower Production
Sunflowers are a promising crop for low-input farming in South Africa because they are more resilient than other crops. However, they have two significant resource demands:
- Water: Sunflower seeds require a lot of water for germination. It takes an astounding 6,792 liters of water to produce just one kilogram of refined sunflower oil.
- Carbon Footprint: Sunflower production and transportation carry a high carbon footprint. Producing one kilogram of sunflower seed oil emits approximately 3.3 kg of CO2 equivalent—the same as a car driving 12.5 kilometers.
Despite their potential, sunflowers account for only about 3.8% of the total cultivated area in South Africa. This limited production has a direct impact on consumers.
The Rising Cost for Consumers
Over the past two months, sunflower oil and canola oil prices have soared by 55% and 40%, respectively. Consumers are feeling the pressure, with a 2-liter bottle of vegetable oil expected to reach between R100 and R120. These price hikes are projected to continue well into 2023.
According to the Bureau for Food and Agricultural Policy, imports of seeds, oil, and cake have been steadily increasing to meet rising domestic demand. This is surprising, given that South Africa has roughly double the crushing capacity needed for the number of sunflower seed it produces locally.
So, why can’t the local industry fill the import gap and ramp up production? The primary answer is water scarcity.
Water scarcity has long been a challenge for South Africa’s agricultural sector, and the sunflower industry is no exception. Limited access to reliable water sources affects crop yields, preventing farmers from expanding their production. Furthermore, unpredictable rainfall patterns, exacerbated by climate change, make it difficult to plan and manage irrigation effectively. Even regions traditionally known for farming sunflowers are facing declining water availability, which stifles growth in an industry already under pressure. As a result, the reliance on imports continues to grow, raising questions about the long-term sustainability of local sunflower production. Addressing water scarcity will be critical to strengthening the industry and reducing dependence on foreign imports.
