Better farming techniques across the world could lead to storage of 31 gigatons of carbon dioxide a year.

Marginal improvements to agricultural soils around the world would store enough carbon to keep the world within 1.5C of global heating, new research suggests.

Farming techniques that improve long-term fertility and yields can also help to store more carbon in soils but are often ignored in favor of intensive techniques using large amounts of artificial fertilizer, much of it wasted, that can increase greenhouse gas emissions.

Using better farming techniques to store 1 percent more carbon in about half of the world’s agricultural soils would be enough to absorb about 31 gigatons of carbon dioxide a year, according to new data. That amount is not far off the 32 gigaton gap between current planned emissions reduction globally per year and the amount of carbon that must be cut by 2030 to stay within 1.5C.

The estimates were carried out by Jacqueline McGlade, the former chief scientist at the UN environment program and former executive director of the European Environment Agency. She found that storing more carbon in the top 30 centimeters of agricultural soils would be feasible in many regions where soils are currently degraded. READ further from the source above
