Introduction to regenerative agriculture

As the world grapples with the intensifying effects of climate change, the need for sustainable solutions has never been more urgent. A promising approach to addressing this challenge lies in regenerative agriculture, a farming method that not only focuses on improving soil health but also actively works to sequester carbon dioxide (CO₂) from the atmosphere. Inspired by ancient agricultural practices that have long understood the importance of working in harmony with nature, regenerative agriculture offers a profound pathway to carbon removal and climate change mitigation.

What is regenerative agriculture?

What is regenerative agriculture?

Regenerative agriculture is more than just an agricultural technique; it is a holistic approach to farming that emphasises the restoration of soil health and the rejuvenation of ecological systems. This approach goes beyond conventional farming practices, which often use harmful substances and depletes the land, leading to increased greenhouse gas emissions. In contrast, regenerative agriculture creates a more sustainable relationship with the earth, prioritising both environmental health and food production. By using methods that improve soil quality, enhance biodiversity, and enable natural nutrient cycles, regenerative agriculture provides a way to work with nature rather than against it.

At the heart of regenerative agriculture is the idea of improving soil health. Healthy soil serves as one of the planet’s most effective carbon sinks, with the ability to absorb and store vast quantities of CO₂ from the atmosphere. By implementing farming practices that increase the organic matter in the soil, regenerative agriculture helps sequester carbon while simultaneously improving soil fertility and crop yields.

Regenerative agriculture is based on photosynthesis whereby plants absorb CO₂ from the atmosphere and convert it into sugars, which fuel their growth. Some of these sugars are released through the plant roots into the soil, where they feed beneficial microorganisms. These microorganisms, in turn, support plant health by enhancing nutrient availability, improving soil structure, and offering natural pest protection. This symbiotic relationship between plants and soil organisms is key to building soil organic matter, increasing its carbon-sequestering capacity, and enhancing soil fertility.

The core principles of regenerative agriculture

 The core principles of regenerative agriculture

Regenerative agriculture encompasses a range of practices designed to restore and maintain healthy ecosystems. These practices not only contribute to carbon removal but also help to increase agricultural productivity and resilience. The core principles of regenerative agriculture include:

  1. Soil Health Improvement: At the foundation of regenerative agriculture is the improvement of soil health. This involves increasing soil organic matter (SOM) and enhancing soil microbiology. Techniques like cover cropping, no-till farming, composting, and rotational grazing help restore soil fertility and boost the soil’s carbon sequestration potential.
  2. Biodiversity Promotion: Regenerative agriculture encourages the integration of diverse plant and animal species into farming systems. By promoting biodiversity, regenerative farming helps create resilient ecosystems that naturally control pests, promote pollination, and support soil health.
  3. Water Management: Healthy soils play a critical role in water retention, reducing runoff and erosion while increasing drought resilience. By improving water infiltration and holding capacity, regenerative agriculture enhances the water cycle, ensuring crops receive the moisture they need, even in arid conditions.
  4. Reduced Chemical Use: Regenerative farming minimises or eliminates the use of synthetic chemicals, such as pesticides, herbicides, and chemical fertilisers. This reduction enables natural nutrient cycling, reduces environmental contamination, and encourages a healthier farming ecosystem.
  5. Adaptive grazing techniques: Using rotational grazing enhances regenerative agriculture by promoting soil health, increasing carbon sequestration, and supporting biodiversity. These methods allow pastures to recover between grazing periods, improving vegetation growth and soil organic matter while reducing erosion.
What is soil organic carbon and its role in carbon removal

What is soil organic carbon and its role in carbon removal?

Soil organic carbon (SOC) is the carbon component found in organic matter within the soil. It is a crucial element in soil health and plays a fundamental role in carbon sequestration. The restoration of degraded soils and the implementation of regenerative agricultural practices have the potential to significantly increase SOC levels, effectively removing CO₂ from the atmosphere.

Healthy soils act as one of the earth’s largest carbon reservoirs, storing more CO₂ than both the atmosphere and vegetation combined. If managed effectively, soils could sequester up to 5 billion tonnes of CO₂ annually (FAO, 2021). This makes soil restoration and the management of SOC a critical strategy for addressing climate change.

How regenerative agriculture fights against climate change

How regenerative agriculture fights against climate change

As global efforts to combat climate change intensify, regenerative agriculture serves as a powerful tool for carbon removal. The process of soil carbon sequestration not only helps to mitigate the effects of climate change but also enhances the resilience of agricultural systems in the face of extreme weather events, droughts, and soil erosion.

By adopting regenerative practices such as no-till farming, cover cropping, and agroforestry, modern agriculture can restore the land’s ability to sequester CO₂ while simultaneously boosting soil fertility and increasing crop yields. These methods create a virtuous cycle whereby healthy soils support healthy crops, which in turn provide food for humans and livestock while contributing to a healthier planet.

At COP21 in Paris, where the Paris Agreement was signed, the 4 per 1000 Initiative was also introduced, highlighting soil carbon sequestration as a critical strategy for achieving global climate goals. By enhancing soil health and increasing carbon storage in the ground, regenerative agriculture provides a scalable solution for reducing atmospheric CO₂ and mitigating the impacts of climate change. (Global Climate Action, 2023)

The 4/1000 initiative

The 4 per 1000 Initiative – Soils for Food Security and Climate is a global effort launched in 2015 during  COP21 (the Paris Climate Conference) to promote soil health as a key strategy for combating climate change and enhancing food security. The initiative’s name, “4 per 1000,” comes from the concept of increasing the amount of carbon in the world’s soils by just
0.4% per year (or 4 grams per kilogram) could have a significant impact on reducing the rise of atmospheric CO₂.

Goals and Objectives

The main objective of the 4 per 1000 Initiative is to increase the global soil organic carbon (SOC) stocks through sustainable agricultural practices. This increase in soil carbon can potentially offset a significant portion of annual global greenhouse gas emissions, stabilising the climate while improving soil fertility. Key goals include:

  • Climate Mitigation: Enhance soil carbon sequestration to absorb CO₂ from the atmosphere, reducing the impact of greenhouse gas emissions.
  • Food Security: Improve soil health, which leads to better crop yields, increased food security, and more sustainable agricultural systems.
  • Sustainable Land Use: Promote agricultural practices that are regenerative and sustainable, like agroecology, agroforestry, cover cropping, no-till farming, and crop rotation.

How It Works

The 4 per 1000 Initiative encourages countries, farmers, scientists, and stakeholders to adopt agricultural techniques that increase soil carbon content. The idea is that even a small annual increase in soil carbon content (by 0.4%) globally would sequester enough CO₂ to help offset current anthropogenic emissions, particularly from fossil fuels and deforestation.
(The International “4 per 1000” Initiative, 2016)

Which Sustainable Development Goals (SDGs) does soil organic carbon support?

Which Sustainable Development Goals (SDGs) does Soil Organic Carbon support?

Soil organic carbon management is directly tied to several of the United Nations Sustainable Development Goals (SDGs), which focus on creating a more sustainable and equitable world. These goals include:

  • SDG 15: Life on Land – Regenerative agriculture contributes to land restoration and biodiversity conservation, ensuring the health of ecosystems and the protection of natural resources.
  • SDG 13: Climate Action – Soil carbon sequestration plays a vital role in climate mitigation by capturing CO₂ and reducing greenhouse gas emissions.
  • SDG 2: Zero Hunger – SOC improvement boosts soil fertility, increasing agricultural productivity and food security, particularly in regions facing food insecurity.

The management of soil organic carbon is also instrumental in achieving broader environmental objectives. As soil carbon levels increase, so does soil health, which in turn supports increased agricultural productivity, improved water retention, and better resistance to erosion and drought.

The future of regenerative agriculture

The future of regenerative agriculture

The future of agriculture lies in practices that restore rather than deplete the earth’s resources. By adopting regenerative agricultural methods, we can revive the health of the soil, promote biodiversity, and mitigate the effects of climate change. However, this will require a concerted effort from farmers, policymakers, scientists, and consumers alike to support and invest in regenerative farming techniques.

Regenerative agriculture provides a powerful solution for carbon removal and climate change mitigation. By drawing inspiration from Indigenous wisdom and combining it with modern scientific understanding, regenerative agriculture offers a pathway to a sustainable future—one that is rooted in harmony with the earth. By restoring soil health and enhancing its ability to sequester CO₂, we can create a more resilient, sustainable, and food-secure world for generations to come.
