change is a process and that the necessary transformation of the world economy will not be decided at one conference or in one agreement. “More than one billion people globally lack access to electricity, and billions more still burn wood and dung for their basic energy needs. Our HighEnergy Planet, a new report from an international group of energy and environment scholars, outlines a radically new framework for meeting the energy needs of the global poor. Historically, the soil carbon pool has been a major source of atmospheric carbon dioxide with likely more than 78 GtC lost from grazing and cropping lands. The transfer of soil carbon to the atmosphere has created a carbon deficit in agricultural soils. Soils now contain a lower organic content than before conversion to agriculture. In many regions it has led to a spiral of decline to desertification. The rich ecology of living soils – fungi, insects, bacteria, vegetation – in a highly productive symbiosis gives way to bare earth. Plants create sugars from carbon and sunlight and they feed organisms in the soil with exudate from the roots. Organisms which in turn create environments that break down soils and release nutrients – bacteria fix atmospheric nitrogen. It is a living system that can become unbalanced and lose organic matter. The water holding capacity of soils is reduced.
