The committee held a webinar on September 14 and a workshop on September 19, 2017, in Fort Collins, Colorado, to explore the current state of knowledge on the potential or capacity of land management practices as a CDR approach, the research that could help achieve this capacity and to estimate the impacts of land management practices across multiple scales, the state of knowledge on policies and incentives, and the socio-economic constraints on soil carbon sequestration and forest carbon storage activities. This Proceedings of a Workshop -- in Brief summarizes the presentations from both the webinar and workshop.

Factors that control forest carbon storage include climatic changes, natural disturbance (e.g., 3 Carbon dioxide equivalent (CO2e) is used to aggregate different greenhouse gases in a common unit.

He noted that detecting differences in SOC accumulation at different soil depths is a big challenge. Biological carbon sequestration can be achieved through afforestation, changes to agricultural practices, soil carbon sequestration (SCS)

Steve Shafer from the Soil Health Institute explained how managing soil health (the capacity of soil to function as a vital living ecosystem that sustains plants, animals, and humans) is very closely related to managing soil carbon: sequestering carbon involves soil health management practices (see Figure 3)

and enhance soil health; how to estimate the practical limits of SCS and how to factor in different soil types/environments; and how much variation is introduced by different crops and management systems. He thinks that more data is needed for establishing baselines for soil health at regional and national scales; identifying trends in changes in soil health; establishing a context to interpret soil health information; supporting selection of land management practices to improve soil health and benefit agricultural production and natural resources; and providing information to policy makers.

Dr. Soussana considers the following to be challenges with SCS as a CDR approach: increasing the amount of carbon returning to soil, stabilizing fertility, and monitoring and preserving carbon stocks; and adoption and permanence of improved practices.

; positive but stringent assessments of efforts like the 4/1000 initiative15 for increasing soil carbon storage; new research, synthesis, and modeling efforts for root inputs as a tool for increasing SOC; and increased data collection, data mining, and use of networks (e.g., the International Soil Carbon Network, ISRIC, etc.)

Commercial crop agricultural systems can sequester carbon at a cost that is competitive with non-agricultural systems, said John Antle from Oregon State University. Implementation of SCS practices depends on the physical potential as well as the economics, behavioral factors, and institution setting and policy.

20 C-AGG is a multi-stakeholder coalition that builds capacity for the development and adoption of voluntary incentives, programs, and policies to reduce GHG emissions from the agricultural sector. C-AGG participants include agricultural producers and producer groups, scientists, environmental NGOs, carbon market developers, methodology experts, investors, and other proponents of voluntary agricultural GHG mitigation opportunities.
