Uwe Grewer & al. This article analyses the greenhouse gas (GHG) impact potential of improved management practices and technologies for smallholder agriculture promoted under a global food security development program. Under 'business-as-usual' development, global studies on the future of agriculture to 2050 project considerable increases in total food production and cultivated area.

Arun Jyoti Nath, Rattan Lal, Gudeta Weldesemayat Sileshi, Ashesh Kumar Das. The “4 per Thousand” initiative was launched at the 21st Conference of Parties (COP21) in December 2015 to address global climate change through the aspirational goal of increasing soil organic carbon (SOC) stock of the world to 40-cm depth by an average annual rate of 4%.

Soil organic carbon (SOC) balance is an important component of the terrestrial carbon (C) budget. However, effect of cropland management changes on SOC dynamics has not been recently assessed in the tropics.

Marc Corbeels & al. - CIRAD. The 4‰ initiative launched by the French government at COP21 in Paris in December 2015 aspires to increase global soil organic carbon (SOC) stocks at a rate of 0.4% per year.

Vincent Poirier, Catherine Roumet, Alison D.Munson. Plant roots contribute substantially to the formation of stable soil organic matter (SOM), and there is evidence that species differ in their contribution to SOM stabilization.

Claire Chenu, Denis A.Angers, Pierre Barré, Delphine Derrien, Dominique Arrouays, Jérôme Balesdent. Recent initiatives, such as the United Nations declaring 2015 as the International Year of Soils and the French "4 per 1000" initiative call attention on soils and on the importance of maintaining and increasing soil organic matter stocks for soil fertility and food security, and for climate change adaptation and mitigation.

Emmanuel Torquebiau & al. L’agriculture climato-intelligente (Climate Smart Agriculture) vise à lutter contre le changement climatique et à s’y adapter tout en combattant l’insécurité alimentaire.

Peter Laban, Graciela Metternicht, Jonathan Davies. La biodiversité des sols et le carbone déterminent en grande partie le rôle de la terre dans la production de nourriture, le stockage de l’eau et l’atténuation des changements climatiques.

Soil has the capacity to bind large quantities of carbon in the long term. An international team of researchers is now advocating effective use of this potential.

Bertrand Guenet & al. To respect the Paris agreement targeting a limitation of global warming below 2°C by 2100, and possibly below 1.5°C, drastic reductions of greenhouse gas emissions are mandatory but not sufficient.

Alicia Ledo & al. This study evaluates the dynamics of soil organic carbon (SOC) under perennial crops across the globe. It quantifies the effect of change from annual to perennial crops and the subsequent temporal changes in SOC stocks during the perennial crop cycle.

Arnoult, Thomas Eglin, Dominique Masse, Mohamed Habibou Assouma, Vincent Blanfort, Claire Chenu, Lydie Chapuis-Lardy, Jean-Michel Medoc and Saidou Nourou Sall. The Paris Agreement calls for limiting global warming below 2°C. The “4 per 1,000 Initiative: Soils for food security and climate” was launched in 2015 to increase soil organic carbon sequestration with three objectives: mitigation of climate change, adaptation to climate change and improved food security.

The capture and use of carbon dioxide to create valuable products might lower the net costs of reducing emissions or removing carbon dioxide from the atmosphere. Here we review ten pathways for the utilization of carbon dioxide.
