FairCarboN programme: aiming for carbon neutrality
To meet the Paris Agreement’s goal of limiting global warming by 2050 to well under 2° C, carbon neutrality must be achieved. Here terrestrial ecosystems play a pivotal role by helping to reduce emissions and, through carbon sequestration, offset those that are unavoidable.
Both functions must be performed while preserving natural ecosystems and ensuring the sustainability of managed and semi-natural ones. Their capacity to provide other ecosystem services – supplying biomass, providing adequate water of sufficient quality, and preserving biodiversity – needs to be maintained or enhanced.
This requires substantial multidisciplinary advances in our understanding of carbon dynamics in terrestrial ecosystems, of carbon sinks and flows at different spatiotemporal scales, and of interactions between the carbon cycle and other biogeochemical cycles, including the water cycle, all within the context of global changes.
Identifying the conditions for a successful transition to carbon neutrality
The FairCarboN exploratory PEPR should make it possible to precisely determine the contribution of continental ecosystems – including natural, forest, agricultural, freshwater, coastal, urban, and rurban environments – to climate change mitigation, and to identify the ecological, agronomic, and socioeconomic mechanisms that can be activated for the transition to carbon neutrality.
To that end, FairCarboN will capitalize on French research teams and infrastructures in mainland France, French overseas departments and territories, and other countries, including those of the Global South, thereby consolidating French leadership in the area of carbon management within continental ecosystems.
The PEPR’s two steering bodies are flanked by six partners from the world of academia and research, including CIRAD, with recognized, complementary expertise, that will sit on the strategic committee.
The project team, headed by INRAE and CNRS, comprises around fifteen scientists specializing in the main fields concerned by the PEPR. This team will benefit from the insights of an international scientific committee and a stakeholders’ committee, which will also help coordinate FairCarboN activity with ongoing international initiatives and ensure broad mobilization of all parties around the PEPR.
Scienitifc, environmental, socioeconomic and policy issues
FairCarboN will have a meaningful, direct, and concrete impact on a range of issues:
- scientific: by expanding knowledge, enhancing expertise within research infrastructures, creating databases and a new generation of shared and open computer models, producing more international scientific publications, and building a worldwide reputation;
- environmental: through solutions to reduce greenhouse gas emissions and increase carbon sequestration while maintaining ecosystem sustainability;
- socioeconomic: charting courses to carbon neutrality with the various stakeholders (eg farmers, foresters, industrial firms, environmental agencies, civil society, NGOs, and policymakers), assisting authorities as they pursue these courses on national and subnational levels, and implementing indicators and decision-making tools to help parties involved contribute to the carbon neutrality transition;
- policy: transmitting essential programme data via summaries and indicators for use by government officials, and helping to draft and evaluate public policies.
An initial call for proposals has been issued
An initial call for proposals from the whole community, issued on 11 April, seeks to spur progress in our understanding of key processes governing the carbon cycle (eg links with other cycles, plant biomass production and recycling, latitudinal and longitudinal flows, greenhouse gas volumes, carbon sequestration and emissions, and public policy effects).
Engagement with the scientific community during the project definition phase will create conditions for the emergence of broad, coordinative multidisciplinary consortia needed to deepen our knowledge of these complex systems.See the call for proposals
Five target projects
Five target projects, with a budget ranging from €1.5 million to €7 million, will be launched by 2023 .
One, in which CIRAD will be participating, will create an unprecedented database to track changes in soil and plant biomass carbon pools. Its use by the modelling community, through PEPR stimulus, will give rise to a new generation of models simulating carbon dynamics within continental ecosystems with greater precision.
Another will develop a multi-agent modelling platform for the integrated evaluation of regional bioeconomic systems. The platform will be a key vehicle for the coordination of ‘scenario labs’ bringing together scientists and stakeholders in five pilot regions – reflecting diverse bioeconomic priorities – in mainland France, overseas French departments and territories, and countries of the global South, including Réunion and Senegal, in which CIRAD will be involved.
The three remaining projects will provide targeted support for existing research infrastructures, to increase and harmonize monitoring of continental ecosystems with state-of-the-art instrumentation. CIRAD will also be involved in that targeted support of flux tower infrastructures and GHG measurement trials within cropping systems.
Education through research
Finally, research-based educational initiatives (eg workshops, instructional modules, and online resources) and international exchanges will be organized to train tomorrow’s men and women researchers, engineers, and technicians committed to following the path to carbon neutrality.
(1) Exploratory PEPRs target emerging fields of science or technology to receive French government coordination and support. They are financed through the research component of the PIA4 programme and the France Relance economic recovery plan. Projects that become exploratory PEPRs are selected by an international jury through a rigorous process..
(2) The extensive reach and collaborative network of the French research ecosystem ensures coverage of an immense range of soil climate conditions and sociotechnical systems in temperate, Mediterranean, tropical, arctic, and subarctic zones. This is evident in the wealth of networks, research infrastructures (e.g. AnaEE France, eLTER-France RZA and OZCAR, ICOS France, and SNO observation networks), and scientific as well as economic partnerships in France and abroad.
