Threats on the biodiversity: The deforestation of L? Africa takes worrying proportions
Automatically translated into English thanks to WorldLingo
A race speed is committed on a planetary scale to preserve a universal common good: million square kilometres of forests which contribute to the balance of nature and the climate. At the current rate/rhythm, more than 140.000 km2 of forests are destroyed each year, that is to say about the surface of Greece.

More and more of are roads open in the wet forests D? Central Africa to facilitate L? exploitation of their wood, to start with invaluable wood like the mahogany. The pressure S? increases on these virgin forests. To quantify L? advanced deforestation, researchers of “Woods Hole Research Center” of Falmouth publish, within the framework of their project “Integrated system of follow-up of the forests in Africa Centrale”, an article which shows an acceleration of deforestation in Africa Centrale. Has the article entitled “Expansion off Industrial Logging in Africa Exchange” rested on more than 300 images of the Landsat satellite covering 4 million km ² in Africa central and making it possible to follow the progression of the forest roads for thirty years (1973? 2003).
Before this work, there were few reliable data available for the follow-up of the forestry development as well legal as illegal in under area

Of the collected data, the researchers estimate that nearly 30% of the forests of central Africa (second tropical forest solid mass of planet after Amazonia) are delivered to the exploitation of wood. They listed 51.916 km of roads D? forestry development in this area, which includes/understands Cameroun, the Republic of Central Africa, Equatorial Guinea, Gabon, the Republic of Congo and the democratic Republic of Congo (DRC). The construction of the forest roads passed 156 km per annum between 1976 and 1990 to 660 km per annum since 2000 to Congo-Brazzaville and from 336 km per annum between 1986 and 1990 to 456 km per annum between 2000 and 2002 in DRC. These open roads for the demolition of wood account for 38% of all the traced roads. Through these data on the forest roads, the authors want to show that the forests dense and wet Basin of Congo are also inaccessible only a few years ago, which should increase deforestation and the threats on the biodiversity.

With L? do current hour, more than 30% of these forests (that is to say 600.000 km2) make L? object of forest concessions and 12% only are protected, specify Laporte and its colleagues. L? is future of these wet forests threatened by a nondurable exploitation of the resources, underline the researchers, and L? does opening of the roads allow the game D hunters? to reach increasingly moved back areas, threatening survival of certain species.

If it is necessary to find a cause utility with the protection of the biodiversity, it is enough to mention that the man draws his food resources there, but also raw materials necessary to its life.
And the man in all that? It is with C? ur of the biodiversity and does not cease interacting with it.
“If L? there is habit to stress that L? is man an accountant in front of the other men and in front of the future generations, it is also important to underline qu? it is also responsible in front of the other species which make the life” (Paul Vergès, president of L? ONERC).
