Limits to achieving '4 per 1000' target

摘要

The "4 per 1000" initiative (see article in AN4/16) was launched by France in December 2015 at COP21. It aims at an annual growth rate of 0.4 per cent in the soil carbon stocks in agricultural soils, as a way to remove carbon dioxide from the atmosphere and contribute to climate mitigation. This would also lead to other benefits that come with increased soil carbon, such as soil fertility, water infiltration and ease of tillage.
