Traditional Olive Oil Production: Carbon Storage and Methods
Traditional olive oil production reflects a sustainable farming approach, producing high-quality oil while contributing to carbon storage and environmental health.
Key Features of Traditional Olive Groves
Traditional olive groves are defined by their low-intensity farming methods, which emphasize sustainability over maximizing yields. These groves are typically composed of old trees spaced approximately 8 meters apart, creating a low-density layout that encourages biodiversity. Unlike intensive systems, traditional groves rely on rainfed agriculture, drawing water from natural rainfall instead of large-scale irrigation. They also minimize labor, materials, and agrochemical inputs, instead allowing natural processes to sustain the ecosystem.
Beyond their sustainable farming practices, these groves play a critical role in preventing environmental degradation. They reduce runoff by over 41.9% and sediment loss by 52%, showcasing their ability to protect the landscape from erosion and water loss.
Carbon Storage in Traditional Farming
One of the standout benefits of traditional olive farming is its ability to capture and store carbon dioxide (CO₂) effectively. Research from the University of Jaén highlights that traditional olive groves remove 5.5 kilograms of CO₂ equivalent from the atmosphere for every kilogram of oil produced - nearly double the amount sequestered by intensive farming methods, which capture only 2.7 kilograms per kilogram of oil. Moreover, maintaining green cover in these groves significantly enhances carbon sequestration, storing twice as much CO₂ as bare soil.
The use of organic fertilizers and other natural management practices further boosts their carbon storage capacity. These methods not only enhance soil health but also contribute to a positive carbon balance. The longevity of olive trees, which can live for centuries or even millennia, amplifies these benefits over time.
"The application of organic fertilizers and facilitating temporary spontaneous cover crops achieve a positive carbon balance and reduce the negative impacts of olive cultivation." - Lázuli Fernández, University of Jaén
These practices highlight the role of traditional olive farming in mitigating climate change through effective carbon management.
Climate Benefits of Traditional Practices
Traditional olive oil production offers a broad range of environmental benefits that extend beyond carbon storage. These groves act as natural carbon sinks, capturing substantial amounts of CO₂ while simultaneously improving water retention and soil health. For instance, olive groves in Estepa, Andalusia, sequester 412 metric tons of CO₂ equivalent annually, turning olive oil production into a climate-positive activity.
By avoiding synthetic fertilizers and herbicides, traditional methods reduce emissions tied to chemical inputs. Instead, they rely on natural soil fertility and biological pest control, further lowering their environmental impact.
"Olive groves are now recognized as part of the solution against climate change." - Dr. Abderraouf Laajimi, deputy executive director of the International Olive Council
According to the International Olive Council, producing just one liter of olive oil captures 10.65 kilograms of CO₂ from the atmosphere. On a global scale, the cumulative effect of olive oil production is comparable to offsetting the emissions of a city with 9 million residents. This remarkable impact underscores the potential of traditional olive oil production to contribute meaningfully to global climate goals, setting a high standard for comparing the environmental trade-offs of modern farming practices.
Modern Olive Oil Production: Efficiency vs. Climate Costs
Modern olive oil production has shifted toward more intensive farming methods, boosting yields significantly but raising concerns about environmental impacts.
High-Density and Super-High-Density Olive Groves
The scale of modern olive farming is a far cry from traditional methods. High-density groves pack 200 to 600 trees into a single hectare, while super-high-density systems squeeze in 1,000 to 2,000 trees per hectare. By comparison, traditional groves typically host just 80 to 120 trees per hectare.
This approach is quickly gaining traction worldwide. For example, super-high-density groves now make up 4.3% of global olive grove areas, and in Andalusia, Spain, their footprint is expanding by over 25% annually.
Modern systems bring certain efficiencies. They require less labor, use water more sparingly, and reduce the need for fertilizers. In California’s Sacramento Valley, olives consume up to 50% less water than other major crops like walnuts, almonds, and pistachios. However, these gains come with a catch: super-high-density groves need to be replanted every 20 years. This frequent renewal process involves land preparation, planting new trees, and disposing of old ones, adding to the environmental toll. While these methods improve productivity, they also create a distinct carbon footprint.
Carbon Footprint of Modern Methods
When comparing carbon capture, traditional olive groves outperform their modern counterparts. A study by the University of Jaén found that intensive systems capture only 2.7 kilograms of CO₂ equivalent per kilogram of oil produced, whereas traditional groves capture 5.5 kilograms.
Farming activities account for 76.3% of the overall carbon impact in these modern systems. The reliance on nitrogen fertilizers, herbicides, and other agricultural chemicals not only increases direct emissions but also reduces the soil’s ability to store carbon. Water usage is another concern. Producing one ton of olive oil requires 14,500 cubic meters of water - far more than crops like linseed (9,400 cubic meters), groundnut (7,500 cubic meters), or sunflower (6,800 cubic meters). These factors highlight the environmental trade-offs of modern olive oil production.
Efficiency Gains vs. Climate Trade-Offs
While modern systems offer higher yields and reduced labor costs through mechanization, they often sacrifice some of the climate benefits traditionally associated with olive oil production.
Biodiversity is another area impacted by intensive farming. Organic olive groves, for example, support 40% more plant species compared to conventional intensive systems. Additionally, super-intensive orchards have been shown to negatively affect wintering bird populations, with species richness declining significantly. However, Beatriz Lozano, a soil researcher from the University of Córdoba, offers a nuanced view:
"There is not much difference between the impact of traditional cultivation and that of intensive and super-intensive cultivation on biodiversity. In the latter two cases, it only results in a larger surface area being covered".
The expansion of super-high-density systems also risks habitat loss and reduced ecosystem complexity, which could diminish biodiversity and disrupt ecosystem services over time.
Despite these challenges, integrating organic farming practices into intensive systems shows potential for minimizing environmental impacts. This indicates that the overall climate effect of olive oil production depends not just on grove density, but also on the farming methods employed.
The industry faces a delicate balancing act: achieving short-term efficiency while ensuring long-term environmental sustainability. Blending the productivity of modern methods with the carbon-capturing benefits of traditional practices will be key as the sector moves forward.

Strategies for Reducing Carbon Impact in Olive Oil Production
The farming phase is responsible for a whopping 76.3% of the total carbon emissions in olive oil production. However, both traditional and modern producers have actionable ways to lower their carbon footprint without compromising on quality. Let’s dive into some practical strategies that balance environmental responsibility with maintaining production standards.
Low-Carbon Farming Practices
One of the most impactful ways to cut down on carbon emissions is by transforming olive groves into carbon sinks instead of carbon sources. Research highlights their potential: globally, olive groves could remove around 47 million tons of CO₂ annually, with each hectare capturing 4.5 tons of CO₂ per year. That’s a significant contribution to combating climate change.
The foundation of low-carbon farming lies in soil management. Practices like minimal or no tillage, combined with organic amendments and cover crops, can turn olive grove soils into effective carbon storage systems.
Using cover crops between the trees, along with organic fertilizers and composted olive mill pomace, can achieve a carbon balance that’s five times higher than conventional farming methods. Additionally, recycling pruning residues by shredding and incorporating them back into the soil creates a closed-loop system, boosting carbon storage while cutting down on waste.
Fertilizer choice also plays a big role. Reducing reliance on synthetic nitrogen fertilizers and opting for organic alternatives can significantly lower emissions tied to farming inputs.
Processing and Waste Management Improvements
Advances in processing technology offer another avenue for reducing carbon emissions, particularly through smarter waste management. Traditional three-phase extraction systems generate a lot of waste compared to the oil yield.
One standout solution is anaerobic digestion, which converts olive pomace and wastewater into biogas rich in methane. This process not only generates renewable energy but also prevents the environmental harm caused by conventional waste disposal. Life Cycle Assessment studies show that anaerobic digestion reduces environmental impacts across multiple categories.
The circular economy approach further maximizes the value of byproducts. For example, olive pomace can be repurposed into biofuel or high-quality fertilizer, while processed wastewater can be used to produce biogas. Some creative uses include using solid waste to absorb oil spills or turning it into livestock feed, which improves meat quality and lowers cholesterol levels.
Processing facilities can also cut emissions by adopting energy-efficient extraction methods. For instance, cold-pressing olives within two hours of harvesting not only preserves quality but also reduces the need for energy-intensive storage and transportation.
