... Adopting a more territorial approach, based on the specificities of winegrowing regions and terroirs, could be more relevant to discussing and planning the dissemination of SCS practices in viticultural land in France. Claessens et al. (2019) conducted a global survey to understand how barriers to the adoption of SCS practices vary at the global level and, more particularly, at the EU level. They also reflected on potential solutions that could be implemented to alleviate some of these barriers. ...
... Though their study was conducted for all types of agricultural systems, it allows for the findings from our paper to be put within the broader context of EU agriculture and to assess how viticulture in France may differ from other agricultural systems in the EU. EU farmers in the study by Claessens et al. (2019) ranked the fact that SOC sequestration is not rewarded financially (no subsidies nor carbon credits available) as their primary barrier to the adoption of SCS practices, followed by the fact that SOC management is not a political priority, and that farm extension services do not have the knowledge nor the capacity to train farmers on technical solutions. This shows that, overall, economic barriers play a much more important role in preventing the adoption of SCS practices on agricultural land at the EU level than they do more specifically in the context of viticulture in France, reflecting the fundamental difference in commodities and supply chains between viticulture, where grapes are not the final product, and other types of cropping systems (e.g., wheat). ...

Furthermore, the solutions discussed by EU farmers in the study by Claessens et al. (2019) had similar implications to those mentioned by French winegrowers in our study in the fact that the majority of solutions ranked as most important by EU farmers dealt with improving capacity building to allow for better communication on how to increase SOC stocks on farmland and improved awareness among the public about SCS practices. Economic solutions were also identified as central in facilitating the adoption of SCS practices by EU farmers in the study by Claessens et al. (2019) and by French winegrowers in our paper. ...
Soil carbon sequestration (SCS) practices on French agricultural land are part of the portfolio of actions available to policymakers in the field of climate change mitigation and are central to the success of the “4 per 1,000” initiative, launched by France in 2015. To date, there has been limited research considering their applicability to vineyards. A survey was circulated to 506 French winegrowers to identify the adoption rate of six SCS practices in the viticultural sector (applying organic amendments, using biochar, returning pruning residues to the soil, no-tillage, cover cropping, and introducing or preserving hedges in the vineyard) and to explore motives and barriers to adoption. The survey also investigated ways of overcoming barriers to adoption and winegrowers' perception of agri-environment measures. Differences in motivations and barriers between SCS practices were found, and winegrowers themselves suggested a need for improved communication of evidence about SCS practices and better-targeted policy incentives to support adoption.
... At the same time, considerable efforts are required before 2030 to achieve long-term sequestration targets. To date, the implementation of measures for natural sinks is still insufficient in the EU (Paquel et al. 2017;Claessens et al. 2019)). In a recent survey on soil carbon sequestration, stakeholders in the EU identified the following main barriers to implementing sustainable land management measures (Claessens et al. 2019): lack of financial incentives, risks associated with changes in production systems, and lack of advisory services and available information on economic and productivity benefits of sink options. ...

... Lack of financial or regulatory incentives, risks associated with changes in production systems, lack of advisory services and available information on economic and productivity benefits of sequestration options are some of the key barriers to the increased uptake of SOC sequestration measures (Claessens et al. 2019). An important economic barrier is also land leasing, where farmers who lease land have little to no financial incentive to invest in maintaining or increasing SOC management (Amundson und Biardeau 2018). ...
... In this report on Task 2.1, the analysis will mainly focus around the sections 1, 2, 6 and 7. Task 2.2 focuses on sections 3 and 4 and is reported in deliverable D2.2 (Claessens et al., 2019), whereas the results on knowledge needs are reported in deliverable D2.3. ...
Report on the views of stakeholders for potential for SOC management to contribute to SOC sequestration for climate change mitigation and adaptation and for the achievement of SDGs, including how these measures can be implemented, which barriers may constrain this, and which knowledge gaps need to be filled.
Soils are integral to the function of all terrestrial ecosystems and to food and fibre production. An overlooked aspect of soils is their potential to mitigate greenhouse gas emissions. Although proven practices exist, the implementation of soil-based greenhouse gas mitigation activities are at an early stage and accurately quantifying emissions and reductions remains a substantial challenge. Emerging research and information technology developments provide the potential for a broader inclusion of soils in greenhouse gas policies. Here we highlight 'state of the art' soil greenhouse gas research, summarize mitigation practices and potentials, identify gaps in data and understanding and suggest ways to close such gaps through new research, technology and collaboration.
Carbon stored in soils worldwide exceeds the amount of carbon stored in phytomass and the atmosphere. Despite the large quantity of carbon stored as soil organic carbon (SOC), consensus is lacking on the size of global SOC stocks, their spatial distribution, and the carbon emissions from soils due to changes in land use and land cover. This article summarizes published estimates of global SOC stocks through time and provides an overview of the likely impacts of management options on SOC stocks. We then discuss the implications of existing knowledge of SOC stocks, their geographical distribution and the emissions due to management regimes on policy decisions, and the need for better soil carbon science to mitigate losses and enhance soil carbon stocks.
Agricultural lands occupy 37% of the earth's land surface. Agriculture accounts for 52 and 84% of global anthropogenic methane and nitrous oxide emissions. Agricultural soils may also act as a sink or source for CO2, but the net flux is small. Many agricultural practices can potentially mitigate greenhouse gas (GHG) emissions, the most prominent of which are improved cropland and grazing land management and restoration of degraded lands and cultivated organic soils. Lower, but still significant mitigation potential is provided by water and rice management, set-aside, land use change and agroforestry, livestock management and manure management. The global technical mitigation potential from agriculture (excluding fossil fuel offsets from biomass) by 2030, considering all gases, is estimated to be approximately 5500-6000Mt CO2-eq.yr-1, with economic potentials of approximately 1500-1600, 2500-2700 and 4000-4300Mt CO2-eq.yr-1 at carbon prices of up to 20, up to 50 and up to 100 US$ t CO2-eq.-1, respectively. In addition, GHG emissions could be reduced by substitution of fossil fuels for energy production by agricultural feedstocks (e.g. crop residues, dung and dedicated energy crops). The economic mitigation potential of biomass energy from agriculture is estimated to be 640, 2240 and 16 000Mt CO2-eq.yr-1 at 0-20, 0-50 and 0-100 US$ t CO2-eq.-1, respectively.
