Aim

C-arouNd aims to investigate how short and long-term agricultural management practices affect SOM persistence in the soil profile and contribute to inclusion of the effects in national inventories to inform policy to reduce net greenhouse gas emissions and mitigate global change. C-arouNd also aims to synthesize findings from a worldwide consortium of long-term agricultural field experiments with focus on soil organic matter sequestration and persistence.

C-arouNd project summary

With the use of inorganic fertilizers, plant breeding and pesticides, global food production more than tripled in the last 60 years, reducing hunger and poverty by fulfilling the Sustainable Development Goals from the UN 2030 Agenda. However, this progress came at a cost because soil degradation resulted in a reduction of soil organic carbon (SOC) stocks and an increase in greenhouse gas (GHG) emissions and global warming. Agriculture and land use change are collectively responsible for nearly 20% of global greenhouse gas (GHG) emissions, making it one of the most significant contributors to nitrous oxide (N2O) and methane (CH4) emissions. Nitrous oxide arises primarily from the application of synthetic nitrogen fertilizers, while methane emissions result from livestock activity and paddy rice cropping. Promoting agricultural practices that enhance soil carbon stocks and decrease greenhouse gas (GHG) emissions is essential for mitigating global warming. Recognizing this, international initiatives such as the 4per1000 were launched during the COP21 meeting in Paris (2015) with the aim of encouraging the adoption of agricultural practices that boost soil carbon stocks as a strategy for mitigating global warming on a global scale. Moreover, increasing SOC will have positive effects on agricultural production due to increase nutrients and water cycling, and on soil health due to its positive relationship with soil biodiversity. The objective of this proposal is to evaluate the influence of conservationist and regenerative agricultural practices on carbon (C), nitrogen (N) and phosphorus (P) cycling, soil biodiversity and GHG emissions with a particular emphasis on long-term SOC stocks, and processes governing C persistence.

Our Team

In Brazil, the actions planned in this proposal are aligned to some of the most important research challenges defined by Embrapa in its Director Plan. Moreover, the development of conservative agricultural practices aimed at reducing GHG emissions an
In Uruguay, the results of this project will be informative about management practices to increase SOC sequestration and decrease GHG emissions. This project aligns directly with INIA’s research agenda priorities for 2021-2025.
In France, the planned activities of this project are fully consistent with INRAE's national priorities, as they respond to both the new challenges and strategic directions of the institute defined in the #INRAE 2030 document
In Norway, RCN wishes to extend the knowledge on how to reduce the global warming footprint in the country, as well as supporting international collaboration and excellence in research.

In Canada, the proposed study will align with Canada’s objective of increasing soil carbon sequestration with diversified crop rotations which will help to mitigate agriculture’s impact on climate change.
As outlined in the National Climate Change Response White Paper, the South African government seeks to (i) Manage climate change impacts through interventions that build and sustain South Africa’s social, economic, and environmental resilience.
In Namibia, as part of the National Development Plan 5 (NDP 5), there is a drive to increase productivity of subsistence farming, crop rotation; soil enrichment and organic pesticides usage is being encouraged especially in communal lands.
In New Zealand, this project will contribute to improving the national greenhouse gas inventory by reducing uncertainty in changes in soil carbon stocks with changes in land management practices. The findings will inform policy development of guideli
The EJP Soil project aligns with the Ghana Government's initiatives, namely the Planting for Food and Jobs program, as well as the Modernizing Agriculture in Ghana (MAG) program.
In Estonia, the actions and outcome in this proposal support and advise farmers with scientific knowledge for carbon farming to achieve the goals according to “Farm to Fork Strategy”.
In Germany, both BMBF (Federal ministry for research) and DFG (German research foundation) support outstanding research explicitly in international collaboration on climate change mitigation.
In Hungary the planned project is a unique opportunity to provide information and scientific knowledge on carbon emissions from agriculture to policy makers, stakeholders, and farmers.
