The ‘4 per 1000’ (4 per mil) initiative was launched at the COP21 in 2015, with the aim to slow down the increase in atmospheric concentrations of CO2 by annually increasing global soil organic carbon stocks by 0.4 % per year.
This initiative has sparked mixed reaction to the feasibility of achieving this, and discussion over what this means for soil management.
The Society hosted a debate on World Soil Day, 5th December 2017 with cntributions from invited speakers;
- Dr Joanna Clark - University of Reading, UK "Implications for organic soils"
- Professor Claire Chenu - INRA, France "Scene setting and overview of the '4 per 1000' initiative"
- Professor Bridget Emmett - CEH, Bangor, UK "Policy, the national perspective and monitoring"
- Professor David Powlson - Rothamsted Research, UK "Achievability from land management"
The presentations (speaker slides are available by clicking on the title above) and debate were audio recorded and now available on the Society You Tube Channel
