Soil Carbon Sequestration
Soil is the biggest reservoir of carbon on the planet after the oceans and holds four times more carbon than all the plants and trees in the world. However, deforestation and industrial farming has degraded this capacity in 40% of all agricultural soils.
New research published in Science suggests that regenerative farming methods including woodland regeneration, no-till farming, cover crops, nutrient management, manuring and sludge application, improved grazing, water conservation and harvesting, efficient irrigation, agroforestry practices, and growing energy crops on spare lands can help restore soils. This not only improves food security but also has the potential to sequestrate 5-15% of global fossil fuel emissions.
