Climate change has already shown its negative impact on ecosystems, making their mitigation more necessary than ever. In this context, the agricultural sector, while emitting greenhouse gases through its production processes, differs from other sectors such as industry and shipping, as it also functions as a natural mechanism for carbon sequestration through the management of soil resources. This mechanism becomes stronger when sustainable management practices are adopted, which can transform agriculture from a source of emissions into an active carbon sink.
Regenerative agriculture represents a sustainable, alternative, and holistic approach to the management of agricultural land. Its principles include the restoration of soil functions, the enhancement of biodiversity, and the improvement of the long-term resilience of agricultural systems.
This thesis examines the role of regenerative practices in soil organic carbon sequestration, with a focus on tree crops and particularly Mediterranean olive groves. First, the theoretical framework of regenerative agriculture and its connection with the Sustainable Development Goals are presented. Then, the importance of soil carbon for soil functionality is analyzed, and key regenerative management practices are examined, such as permanent ground cover, reduced tillage, and the use of organic inputs.
In the methodological part of the study, the IPCC methodology for soil organic carbon stocks is applied to estimate changes in soil organic carbon (SOC) in a case study of an olive grove located in the Peloponnese, Greece. The analysis is based on standardized factors according to the IPCC Tier 1 approach, in order to estimate changes in carbon sequestration compared to a conventional management scenario.
At the same time, the study explores the potential integration of these practices into carbon markets, highlighting the role of carbon credits as a possible economic incentive for the adoption of sustainable agricultural practices. The inclusion of agriculture in carbon markets could contribute both to enhancing farmers’ income and to achieving climate change mitigation goals.
The results highlight the importance of soil management practices in enhancing carbon sequestration and demonstrate the contribution of agriculture to climate change mitigation.
