23 December 2015, Carbon News Network, Improving soils cuts carbon and grows more food. One straightforward way to combat both climate change and mass hunger is to replace carbon lost from the soil. All sorts of clever, expensive and downright daft ideas for removing carbon from the atmosphere have been suggested, but one of the simplest and most effective – building up carbon in the soil – hardly rates a mention. It is a process that happens naturally, but intensive agriculture, deep ploughing, heavy artificial fertiliser use and cutting down forests have impoverished soils worldwide. If the process could be reversed by adding extra organic matter to the soil each year, then the worst effects of climate change could be averted. Although the issue was hardly raised in the two weeks of negotiations on theParis Agreement in early December, behind the scenes the way farmers produce crops remains central to knowing whether we can hope to avoid the full impact of the warming climate. More than 100 of the 196 countries present in Paris which submitted plans beforehand on how to reduce their own carbon emissions put agriculture, forestry and replacing carbon in soils into their programmes. Better yields Also, on the fringes of the conference, the CGIAR Consortium, a partnership of leading agricultural research organisations, announced a US$225 million five-year plan to mitigate climate change by putting carbon back into the soil while improving developing world agricultural yields. This is part of a much longer-running international initiative started by France,the 4% Initiative, which aims to increase the carbon content of soil by four parts per thousand each year, enough to counteract human interference with the climate from the continued burning of fossil fuels.
