KJWA submission provides scientific guidance to increase Soil Organic Carbon stocks.

KJWA submission provides scientific guidance to increase Soil Organic Carbon stocks.
Following the previous submissions to Decision FCCC/SB2018/L1 on the Koronivia Joint Work on Agriculture (KJWA), a new document focused on Topic 2(c) provides scientific guidance to increase Soil Organic Carbon stocks has been submitted on May 2019.

Following the previous submissions to Decision FCCC/SB2018/L1 on the Koronivia Joint Work on Agriculture (KJWA), a new document focused on Topic 2(c) provides scientific guidance to increase Soil Organic Carbon stocks has been submitted on May 2019.

Stressing the Topic 2(c) importance of improving soil carbon, soil health and soil fertility under grassland and cropland as well as integrated systems, including water management, the new submission was signed by 32 higher education institutions and programs, all members of CIRCASA Consortium or part of its partner’s network. This is a science-based view addressed to policy makers for the upcoming Koronivia workshop, taking place in June 2019 during the UN Climate Change Conference held in Bonn.

The submission highlights the important efforts to archive the Sustainable Development Goals (SDG) linked to soil organic sequestration (SDG 2, Zero hunger, SDG 13, climate action, and SDG 15, land conservation and restoration) made by the scientific community. Several Agricultural National Determined Contributions (NDC) of those SDGs identify soils as a priority for climate change adaptation and this submission aims to provide scientific guidance to countries to build policies and projects on improved SOC and thus enhance their NDC achievements for the 2020 agenda.

Scientists recall the numerous initiatives that have already been put in place by the scientific community in order to enhance the science/policy dialog and provide a scientific assessment as well as the current science-based knowledge for policy advice in relation with Topic 2 (c).

Key messages

Scientists highlight on the submission that increasing organic carbon in agricultural soils would have multiple co-benefits such as food security, adaptation of climate change. Soil Organic Carbon (SOC) have also benefited on soil structure, soil hydrology, ground biodiversity, and nutrient cycles as demonstrates numerous studies.

Nevertheless, Soil Carbon Sequestration (SCS) rate depends on the type of soil, climate, vegetation and land use management. Optimal and sustainable land management (SLM) need to be implemented along with an inclusive reflection with stakeholders, farmers and citizens so SLM can be integrated in a local and appropriated way.

Several efforts need to be done at national, scientific, and policy levels.  On the one hand, national assessments need to be conducted to identify agroecological zones, conditions, and farming systems that are at risk of losing SOC stock or that have the potential for SOC sequestration. In the other hand, scientific tools needs to be developed for assessing and monitoring socked SOC and thus be in the capacity of advice decision-makers to take into account SCS activities. In addition, related policies and measures should be integrated to assure a continuous effort to avoid the release of stored carbon.

In order to ensure the increase of SOC, scientists provide on this submission information concerning the appropriate agricultural practices, costs, as well as key specifities of SOC improvement.

CIRCASA members and partners were strongly involved in the conception of this second submission. Soil Organic Carbon sequestration to mitigate and adapt climate change is indeed at the core of the project and by this document, authors aim to provide scientific advice to accompanying countries to increase their NDCs ambitions. This submission is an important basis for the next steps to come in terms of the science/policy interface.
