International soil carbon sequestration research

90 views

Published on

This presentation by Cristina Arias-Navarro (INRA) was given on the 26 of June 2019 as part of the SB50 side event – Enhancing NDC Ambition Through Soil Organic Carbon Sequestration. Country representatives and experts discussed the potential of soil organic carbon sequestration as a climate change mitigation option and gaps between countries’ current and potential commitments.

International soil carbon sequestration research

  1. 1. International soil carbon sequestration research SBSTA50 Soil Organic Carbon Side Event Bonn, 26th June 2019
  2. 2. 2 • 128 countries include the Agriculture, Forestry and Land Use sector in their pledges • By 2030, a gap of 29 billion tons CO2eq prevents reaching the targeted +1.5℃ maximum global warming threshold • Limiting warming to 1.5°C will require the use of “negative emissions technologies” – methods that remove CO2 from the atmosphere. • Options from land sector could come with considerable impacts on food security ,on clean water and sanitation, as well as on life on land. [Summary for Policymakers, IPCC 2018] Mitigation options and SDGs Mitigation options and SDGs
  3. 3. 3 Humans have created anthropogenic ecosystems (anthromes) which are subject to interlinked land based challenges including climate change adaptation, land degradation and desertification, food insecurity, groundwater depletion, water pollution, biodiversity loss and declining nature’s contribution to people (NCPs) Overlap between the desertification, or land degradation, challenges, the food insecurity (chronic undernourishment) challenge and the climate change adaptation challenge. [submitted Nature , Soussana, Arias-Navarro et al.] Land-based challenges • Identifying and deploying mitigation options to respond to all challenges simultaneously is a major issue for humanity. • Increased SOC has a large potential since it could be deployed with mostly co-benefits.
  4. 4. cross-cutting theme between food security, climate change, desertification and biodiversity • 2-3 times more carbon in soil organic matter than in atmospheric CO2 [IPCC, 2013] • 1.4 Gt C could be stored annually in agricultural soils [after IPCC, 2007, 2014] • Large benefits for food security by increasing crop yields and yield stability for soils initially low in SOC [Lal 2006, Frank et al. 2017] • 10% global crop yield loss by 2050 with land degradation [ITPS, 2016] • soil organic matter is known to increase water filtration, protect water quality and improving soil carbon can increase overall resilience of landscapes. [Lehmann & Kleber 2015, Tscharntke et al. 2005] • SOC seq is among the cheapest methods with the greatest potential [UNEP,2017] Soil carbon sequestration: a major mitigation option
  5. 5. METHODS USED BY GRA COUNTRIES FOR ESTIMATING SOC CHANGES FOR THE “CROPLAND REMAINING CROPLAND” CATEGORY. [in prep, Arias-Navarro, Smith, Soussana et al.] Soil carbon: moving from Tier 1 to Tier 2 • Land management practices • Long-term field trials • Soil surveys INTEGRATIVERESEARCH GROUP: Inventories and Nationally Determined Contributions (NDC) Support Network.
  6. 6. Storing carbon in French soils: what potential for the 4 per 1000 target and at what cost? Stockage additionnel absolu (kgC/ha/an) sur 0-30 cm avec le scénario "Insertion et allongement des cultures intermédiaires" Coût de la tonne de C stockée (€/tC) et Assiette maximale technique (AMT) (ha) de la pratique, par région • The potential for additional carbon storage in French agricultural and forest soils is +5.78 Mt C yr-1 in the 0-30 cm horizon (+8.43 Mt C yr-1 over the entire soil depth) +1,9 ‰ [all land uses combined] +3,3 ‰ [agricultural soils] +5,2 ‰ [arable crops] • Management practices to stock more C in soils in France would enable maximum additional storage equivalent to 41% of French agricultural emissions, or 7% of emissions in France. • Half of the potential is at a lower cost than the current shadow price of carbon (55€/tCO2e) • Most of the potential for additional storage is in arable crops (86% of total potential) [Bamiére, Pellerin et al.2019]
  7. 7. • Together with these initiatives and with CCAFS- CGIAR, it has direct outreach to a total of 82 countries accounting for 85% of the world’s total research on soil C sequestration in agriculture Countries partners of CIRCASA, 4p1000, GRA, FACCE-JPI and CCAFS • H2020 CIRCASA has 22 partners including the research secretariats of 4p1000, GRA and FACCE-JPI Develop international synergies concerning research and knowledge transfer on agricultural soil C sequestration at European Union (EU) and global levels.

  9. 9. Developed to structure and integrate existing knowledge on soil organic carbon sequestration in agriculture. This includes the sharing of information, data, and knowledge openly accessible.
