New studies show that there are more and more trees in the world, partly due to causes natural, such as the global increase in CO2 derived from industrial pollution and another due to human action.
Although some regions of South America (Brazil, Paraguay and Argentina) suffer serious problems of deforestation of their forests like India, in other parts of the world such as the USA and Russia, the population of trees has increased, resulting in globally that the Earth is greener than before.
There are more forests on Earth now than 35 years ago
Despite the damage caused by anthropic activity, the human being in its noblest aspect tries to compensate for the damage, in this case with reforestation projects.
The most recent project was carried out in India where the government invested more than 6,000 million euros so that the trees go from covering the current 21% of the total surface of the country to the future 33%. A task of titanic dimensions.
Other magnificent reforestation projects in China, the Philippines, Madagascar, South Korea, Mexico, the Appalachian Mountains and elsewhere are described below.
1. The other Chinese wall
China's problem lay in the advance of the Gobi desert, located in the north of the country, one of the most arid in Asia. Towards the 80 ″ the Gobi advanced at a rate of 3,000 kilometers of surface per year. To stop it, the authorities decided to undertake the largest reforestation project in the world: a gigantic wall of trees that encircles the limits of the desert. Already in 2009, China managed to replant about 500,000 square kilometers of trees.
The Great Green Wall has been criticized for its poor resistance to storms and for affecting the biodiversity of the region.
2. The Philippine forest recovery
The objective of this project in 2011 was to plant 1,500 million trees on 1,500,000 hectares. Years ago, the archipelago had lost forest mass at a rate of 47,000 hectares per year. Since the implementation of the project, the Philippines has recovered its lost trees and added 240,000 new hectares of forests that have been regenerated under the plan.
This program also received criticism for the use of exotic species with the consequent appearance of foreign biodiversity.
3. Madagascar: from nothing to everything
The forests of Madagascar are characterized by their fragility and their value as a tropical ecosystem.
The forests of Madagascar in their maximum splendor, kept great wealth, but due to the indiscriminate use of the land, the cutting and burning of trees, pollution, etc. its forests have been reduced to an alarming 10% in 2007.
Since that year, many non-governmental organizations have taken on the task of recovering part of the lost forests, managing to reforest some 80 million trees throughout the island, recovering landscapes, ecosystems and generating local jobs. through the plan.
4. South Korea and its postwar trees
South Korea almost lost its forests during the Japanese occupation in World War II. The subsequent civil war and the intensive use of the land, mainly to satisfy the needs of a still agricultural economy, also affected the country to the point of leaving it almost without forests.
After the conflicts and with the establishment of the government and the economy, reforestation became a matter of urgency, managing to recover a large part of the lost mass. Today about two-thirds of South Korea is covered by forests.
5. The resurgence of La Mixteca, in Mexico
The arboreal history of La Mixteca, in Mexico had suffered high soil degradation due to economic uses (grazing), poor land use and the immediate consequences of the green revolution.
At one time it was covered with trees, today it still looks like a desert wasteland, but with areas in recovery that are returning the green. Reforestation projects have allowed the planting of more than four million trees since the eighties (pine and alder), greening the area.
6. 60 million trees for the Appalachians
Not only agriculture is to blame for the loss of forests. Mining is another of the high impact anthropic activities in nature.
The Appalachian Mountains, on the east coast of the United States, were for centuries a source of mining wealth for coal reserves. The cost for this activity was high, the degradation of such a special natural landscape.
Since 2005, the Appalachian Region Reforestation Initiative, made up of different conservation organizations, has implemented reforestation programs. The result, more than 60 million new trees in just 35,000 hectares.
7. The sub-Saharan green wall
Inspired by the Chinese experience in the Gobi, a large number of sub-Saharan countries decided to plant a gigantic tree barrier that would slow down the serious desertification of the Sahel and allow thousands of local communities to continue living on their soil.
The wall would be about 8,000 kilometers long and about 20 wide, and the project seeks to promote sustainable land uses that prevent the Sahara from continuing to gain ground to the south.
