Combating Climate Change:
Changes to agricultural practice and forestry management could cut greenhouse gas emissions, buying time to develop alternative technologies. This can be done by farming Out Global Warming Solutions.
Humanity has cut too many trees and by caused an immense desertification. The solution is quite simple: reverse the desertification and start planting trees. This solution will result in reducing the quantity of carbon dioxide in the air. It will also create valuable property that produces financial profits.
Each year, nearly 33 million acres of forestland around the world is cut down, according to the Food and Agriculture Organization of the United Nations. Without action now, most of the world’s tropical forests will be lost by this century’s end. During the last half century, the seemingly endless Amazon has lost at least 17% of its forest cover.
If such losses were cut in half, it could save 500 million metric tons of carbon annually and contribute 12 percent of the total reductions in GHG emissions required to avoid unpleasant global warming, researchers recently reported in Science.
Planting trees remains one of the most cost-effective means of drawing excess CO2 from the atmosphere. Therefore, trees act as carbon sinks, alleviating the greenhouse effect. There are millions of acres of tropical pastures available.
The biome encompasses 6.7 million km2 (twice the size of India) and is shared by eight countries (Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana and Suriname), as well as the overseas territory of French Guiana.
Tree-planting could sequester (remove from the atmosphere) around 1.1–1.6 GT of CO2 per year. That compares to total global greenhouse gas emissions equivalent to 50 GT of CO2 in 2004.
Among proposed changes: more widespread adoption of so-called no-till farming, a practice that involves leaving unharvested crop stalks and other plant matter behind in the field undisturbed by plows and other soil-agitating instruments.
Basically, the carbon stored inside the remains sinks into the soil instead of being stirred up and into the atmosphere when the soil is prepared for planting using conventional means. Such no-till farming provides a double benefit for farmers: improved soils and reduced fuel use, because it negates the need to harvest the stalks with tractors and other equipment.
