Rewetting of previously drained agricultural peat soil coupled with continued cultivation in the form of paludiculture is not widely practiced, and experiments are needed to understand its environmental impacts.
In the INSURE project (INdicators for SUccessful carbon sequestration and greenhouse gas mitigation by REwetting cultivated peat soils) we measured GHG emissions and crop yields in rewetted agricultural fields.
Water-induced soil erosion is a growing concern in the EU, with climate change projections indicating a potential 13-23 % rise in erosion rates.
The variability of soil erosion modelling techniques highlights the need for standardisation of data sets and harmonisation of model parameterisation to allow valid comparisons of policy measures.
The Common Agricultural Policy (CAP) has a limited effect in decreasing erosion risk, as the voluntary measures are often not well targeted to the identified erosionprone areas.
Policymakers should advocate for targeted erosion mitigation measures and elaborate more appropriate assessment protocols including sediment connectivity modelling to improve accuracy in erosion risk assessments.
Soil health is defined through soil indicators, which are assessed using targets and/or thresholds. The challenge is that targets and thresholds are highly site-, managementand climate-specific, and there is not yet a validated assessment system with that level of detail.
With policies worldwide being established to promote soil health, there is an urgent need for the development of a system to assess soils.
We explored four approaches to setting targets and thresholds. Based on stakeholder feedback of the approaches, collected in two webinars (EJP SOIL 2023) and case studies of three approaches, we developed a framework that facilitates both choosing the most appropriate target/threshold method for a given context, and using targets and thresholds to promote soil health.
This policy brief aims at providing a concise overview of the current state of CF schemes in and outside Europe and of research findings derived from the WP8 of the EJP SOIL programme and the Road4schemes project. It builds on existing incentive schemes under the European Common Agricultural Policy (CAP, Reg. EU 2021/2116), and in anticipation of the forthcoming European regulation on carbon removals (COM/2022/672 final), which will play a key role in CF in Europe.
In this context, key challenges and policy recommendations to promote the implementation of a common European CF framework are provided.
In climate change mitigation discussions, technical terms are not always used correctly leading to unintended consequences and exaggerated expectations of the role of soil C for climate change mitigation.
Carbon stock, carbon sink - are they the same thing? And does fixing C in the soil, for example by building up soil organic C, automatically lead to climate change mitigation? In public discussions about climate protection, many such concepts often get mixed up.
