Wine Farmers in South Africa: Diversifying into Olive Trees for a Sustainable Future

Olive Tree Farming in South Africa

South Africa’s wine industry, renowned globally for its diverse and high-quality wines, has long been a pillar of agricultural success. However, like many parts of the world, South African wine grape growers are facing increasing pressure due to global market shifts, price drops, and environmental challenges. In light of these developments, many wine farmers are exploring new ways to diversify their operations, and one option that has gained significant traction is the introduction of super high-density olive trees. This strategy, already seeing success in regions like Australia, offers South African wine farmers an opportunity to remain competitive and sustainable, particularly as global demand for olive oil continues to rise.


Why Olive Trees? The Case for Diversification

The global wine market has been undergoing changes, with oversupply often driving down prices. This has prompted farmers to seek alternative crops that can complement their existing vineyards. One of the most promising options is the cultivation of olive trees, specifically super high-density varieties, which are perfect for South African climates and can thrive alongside grapevines.


Super high-density olive trees offer several advantages:

  • Fast Returns: These trees can bear fruit within two years, significantly faster than traditional olive varieties, making them an appealing choice for farmers looking for quick returns on investment.

  • Utilising Existing Infrastructure: South African wine farmers already have the equipment and infrastructure for vineyards, which can easily be adapted to manage olive groves. This means lower upfront costs and a smoother transition.

  • Market Demand: The global demand for olive oil is booming, with countries like Spain and Italy facing production challenges due to extreme weather and disease outbreaks. This has created a shortage, driving up prices and offering a lucrative opportunity for new olive oil producers.


Benefits of Super High-Density Olive Plantations

Super high-density olive trees are becoming increasingly popular due to their efficiency and productivity. These trees are planted in closer proximity than traditional olive trees, allowing for better use of space and resources. Here’s why this method is gaining traction among wine farmers:


Higher Yields: Super high-density plantings produce significantly more olives per hectare compared to traditional methods. This increased yield translates into higher profits, especially in times of olive oil shortages.


Water and Resource Efficiency: These olive trees require about 30% less water and fertiliser than traditional plantings. In a water-scarce country like South Africa, this is a crucial benefit, allowing farmers to conserve resources while maintaining high productivity.


Mechanised Harvesting: South African wine farmers can use their existing vineyard machinery to harvest olives, making the process more efficient and reducing labour costs. The ability to harvest mechanically also means that larger operations can be managed with fewer workers, which is a big advantage in a labour-intensive industry.


A Growing Olive Oil Market in South Africa

As global olive oil production declines due to unfavourable conditions in Europe, South Africa has a unique opportunity to step in and meet both local and international demand. South Africans are consuming more olive oil than ever before, and much of it is still imported. By planting more olive trees, South African farmers can reduce the country’s reliance on imports while tapping into a growing market.


This diversification also strengthens the local economy. By adding olive oil to their product lines, farmers can offer consumers more locally produced goods, which are increasingly favoured over imports. The development of local olive oil processing facilities, as seen in other wine-producing regions, would further support this new venture, creating jobs and boosting rural economies.


Long-Term Sustainability and Security for Wine Farmers

For many wine farmers, the move to olive trees is not about abandoning their vineyards, but about creating a more resilient and diversified business model. Wine and olive trees complement each other well, allowing farmers to protect themselves against fluctuating wine prices and market instability.


Moreover, super high-density olive trees offer environmental benefits. These groves can be planted using existing vineyard trellises, reducing the need to dispose of old materials like treated pine posts, which are often an environmental hazard when vineyards are removed. This approach ensures that land is used efficiently, reducing waste and supporting sustainable farming practices.


Future-Proofing South African Agriculture

As South Africa’s agricultural sector navigates the challenges of climate change, water scarcity, and fluctuating global markets, diversification has become more than just a business strategy—it’s a necessity. Super high-density olive trees present a viable option for wine farmers looking to safeguard their future. Not only do they offer a quick return on investment, but they also fit seamlessly into existing farm operations and meet the growing demand for olive oil.


In regions like the Western Cape and Stellenbosch, where wine has long been the primary crop, olive trees can bring stability and long-term security. By investing in these fast-growing, high-yield trees, South African wine farmers can diversify their income streams, mitigate risk, and help build a more sustainable agricultural industry.



Wine farmers in South Africa have long been known for their resilience and innovation, adapting to changing market conditions and environmental challenges. By embracing this new crop, South African farmers can not only protect their livelihoods but also contribute to the country’s growing reputation as a producer of high-quality olive oil. With careful planning and investment, the future of South Africa’s wine and olive industries looks bright.
