In a recent study by Wageningen University & Research Centre, management interventions to increase the supply of organic carbon were tested with a linear programming model called NutMatch. NutMatch was applied to crop rotations with different mixtures of organic cattle slurry, pig slurry or compost, or with a mineral fertiliser. The study found that rotational crop residues, cattle slurry and compost each substantially contributed to soil organic carbon accumulation (range 200-450 kg C ha-1 yr-1); contributions of pig slurry and cover crops were small (20-50 kg C ha-1 yr-1). In terms of greenhouse gas emissions, it appears that the trade-offs between carbon inputs and emissions of greenhouse gases (notably N2O) or other pollutants (NO3, NH3) can be substantial.
The global initiative, ‘4 per mil, Soils for Food Security and Climate’ of the Lima-Paris Action Agenda was launched during the December 2015 COP21 in Paris. It includes both an action plan and a research program, and is supported to nearly 150 signatories (including countries, regions, international agencies, the private sector and NGOs).
A Scientific Officer is sought for a two-year tenure to assist in the development of the international research program focussing on soil organic carbon in relation to the challenges of food security and climate change. Development will be supported by CGIAR, the GRA, INRA, CIRAD, and IRD in France; and by other national, European, and international partnerships.
Candidates are required to be trained in soil, environmental, or agricultural science; and to excel both in communicating research results and in organising events. Professional experience (2-5 years) would be appreciated. Working languages are French and English. The position is based at INRA’s headquaters (downtown Paris), and will involve travelling.
Salary is 2480 Euro gross/month (2060 Euro net.month)

Sweden’s EviEM has published a comprehensive database of all research from boreo-temperate ecosystems investigating the impacts of different agricultural management practices on soil organic carbon. Research covering a wide variety of different management practices, including soil amendments (such as lime addition, stubble retention, etc.), crop rotations, fertiliser application (organic and inorganic), and tillage (including reduced/conservation tillage and no tillage) has been categorised. The information has been published as a systematic map, comprised of a report describing the processes behind the review, a database of studies with columns of various descriptive information, and a geographical information system (GIS) that displays the database in an interactive cartographical map.
This week marks the ending of the 2016 Conference of Parties (COP21) in Paris, France, where 195 countries made a legally binding agreement to keep a global temperature rise this century well below 2 degrees Celsius, and to limit the temperature increase even further to 1.5 degrees Celsius above pre-industrial levels. See the agreement
Other outcomes of specific interest for the GRA include:
- The launch of the 4/1000 Initiative, which aims to increase carbon stocks in agricultural soils (notably grasslands and pastures) and forest soils by 4/1000 per year of the soil carbon stock to improve soil fertility and farm resilience. Get involved
- The Climate & Clean Air Coalition (CCAC)’s meeting, where it launched a 5-year scientifically-based policy strategy to substantially reduce emissions of black carbon, methane, tropospheric ozone and HFCs. See more
- New Zealand’s announcement that it will invest an additional $20 million NZD towards the GRA over the next four years. See official media release
The summary from the Soil Carbon & Nitrogen Cycling Cross-Cutting Group Workshop held in Paris, 19 – 21 March 2014, is now available.
The workshop brought together the the CN-MIP, Models4Pastures, COMET-Global and MAGGNET projects which have recently been funded by a multi-partner call, and other modelling groups. Attended by 65 participants from 15 Alliance member countries, the workshop gathered scientists from various GRA research groups, projects and initiatives related to the common topic of agricultural GHG modelling.

This post provides information on the European conference “Green Carbon: Making Sustainable Agriculture Real”.
The Conference will be held April 1-3, 2014 in Brussels, Belgium and will include discussions across four topics.
1. Evidence of carbon sequestration in Europe and carbon offset potential.
2. Contribution of Soil Organic Carbon for ecosystem functions and landscape management.
3. Soil Organic Carbon, soil health and productivity.
4. Economic and policy aspects of “carbon farming”.
The conference is jointly organized by the European Conservation Agriculture Federation (ECAF) and the French Institute for Sustainable Agriculture (IAD) and promoted by the Life+ AGRICARBON project.
Modelling grassland ecosystems under climate change: An introduction to the Global Research Alliance and the AgMIP program
Side event of the 22nd International Grassland Congress, Sydney (September 17, 2013, 12:00 – 14:00)
This event will promote the Global Research Alliance and the modelling project underway in the Soil Carbon and Nitrogen Cross-Cutting Group in collaboration with the AgMIP program.
Please pass the modelling grassland ecosystems flyer [PDF] to colleagues that you know to be attending the Grasslands Congress.
