IPCC Land and Climate change presentation by Jean-François Soussana, 4p1000 initiative day

Presentation at the occasion of the 3rd "4p1000 initiative" day during the COP25 Madrid 2019. December 11, 2019

IPCC Land and Climate change presentation by Jean-François Soussana
The 4p1000 initiative initially, launched during the COP21 by France in December 2015 aims to demonstrate that agriculture, and in particular agricultural soils can play a crucial role where food security and climate change are concerned. This initiative works closely with the CIRCASA project Network.

The 3rd initiative day, has been organized with the support of the Spanish Ministry of Agriculture, Fisheries and Food in December 11 during COP25 in  Madrid. The event, opened by Spanish Minister of Agriculture Mr. Luis Planas and the French Minister, Mr. Didier Guillaume, brought together the 5th meeting of the Consortium of Members and the 4th meeting of the Forum of Partners.

During the high-level interventions, up to 20 "4p1000 partners" around the world presented a range of projects and organisations cooperating with the initiative from politicians, to farmers and international organisations, to scientists, to companies and donors.

At the "meeting of the Forum", CIRCASA Project Coordinator, Jean-François Soussana presented the IPCC special report on Climate Change and Land adopted last August 2019.

Presentation of the IPCC report and the Soil Carbon sequestration.

Greenhouse Gases emissions from the Agricultural sector

J.F Soussana, co-author of the report, pointed out that the emissions from Agriculture Forestry and Land Use (AFOLU) represent near 25% of the total global emissions, if we took a cross-sector approach (transportation, agri-food industry), this percentage is near 37% of the total net anthropogenic emissions. Nevertheless, the IPCC report also studied a range of response options with a mitigation potential for Climate Change from production to consumption. 

Land Degradation

The IPCC land report studies the challenges of Climate Change and mitigation but also the challenges of land degradation, desertification, and food security. As shown in the report, 1/4 of the Earth's free-ice land area is affected by land degradation mostly due to human causes like unsustainable land management. This effect is increased by the actual Climate change and could have serious negative effects on natural resources, food, biodiversity, and livelihood. 

"Indeed, combating land degradation and desertification has strong benefits for climate both in terms of adaptation and mitigation" highlighted JF Soussana during his presentation

Combat desertification appears a clear urgency to contribute to climate change adaptation and has multiple co-benefits for land-based challenges (read the " KJWA submission provides scientific guidance to increase Soil Organic Carbon stocks. " article).

Moreover, the report makes clear that there are several risks to food supply chains, nutrition quality of the crops and food security.

"This report comes with a strong warning message. We are already at 0.85°C global warming, we are already with infrequent price spikes affecting individual countries in terms of the food supplies chains but if we enter into the risky zone of 1.5°C warming, we will have some periodic shocks across regions for food supply chains and if we go beyond 2°C then in sustained food supply disruptions globally. The risks are extremely high for food security"

What are the sustainable land management possible responses? 

Authors of the IPCC report studied a range of land management responses and their global impact on land-based challenges such as Climate change mitigation, adaptation, land degradation, food security, biodiversity, ground water stress, and water quality.

Increase soil carbon content appears to be the only response with a positive impact on all challenges (figure modified from the IPCC SR CCL, SPM and Chap 6, 2019).

Nevertheless, the coauthor Mr. Soussana insists that immediate action is needed. Late action would reduce the potential of sustainable land management options, limit their effectiveness and would have irreversible impacts on some ecosystems.

Rapid action is crucial for climate change adaptation and mitigation. Postponing the action in all sectors would certainly lead to even greater economic impacts in many parts of the world.

Following the IPCC presentation, Cristina-Arias Navarro, CIRCASA scientific officer, presented the project activities and the prospects for an International Research Consortium expected for 2020 which will provide a great possibility for international cooperation. Read our recent article - Towards an International Research Consortium on Soil Carbon.

In CIRCASA we are enthusiasts about these cooperations and will keep working closely with the 4p1000 initiative and its partners, facilitating the dialog and strengthening international synergies.

Stay tuned for the Consortium's meeting conclusions at the 4p1000 webpage.
