Carbon and nitrogen stocks in the soils of the Amazon Region. It also has high temperatures and lots of rainfall.

Powell, Scott R. However, deforestation in Malaysia is increasing faster than anywhere else in the world due to logging, road building, mineral extraction, transmigration, commercial and subsistence farming. This shows that the Amazon forests help reduce global warming by lowering the planet's greenhouse gas levels. However, unless they are paved many of the roads are unusable during the wettest periods of the year. The timber is used to build homes, furniture, etc. Carbon Tropical forests are very important stores of carbon, and in their untouched state act as carbon sinks. Many people are migrating to the forest looking for work associated with the natural wealth of this environment. Ecologists debate about whether systems that have high biodiversity are stable and resilient, like a spider web composed of many strong individual strands, or fragile, like a house of cards. The farmers now artificially fertilise the soil when in the past the nutrient cycle would have done this naturally. This is because the tropical rainforest is a store of carbon, therefore when it is destroyed there is less vegetation to absorb carbon dioxide, and more carbon dioxide is released into the atmosphere by the burning of the vegetation itself.

Logging — This involves cutting down trees for sale as timber or pulp. For the carbon that remains in the soil, when it rains soil erosion will wash much of the carbon away into rivers after initial deforestation and some will be lost to the atmosphere via decomposition too.

We might expect a lush rainforest to grow from incredibly rich, fertile soils, but actually, the opposite is true.

Deforestation of large areas of forest is leading to a decline in biodiversity, with some species of plant and animal becoming endangered or extinct. Rainforests hold most of their nutrients in their live vegetation, not in the soil. Efforts to protect rainforests and other areas of high biodiversity is the topic of the next section. Loggers are interested in all types of wood and therefore cut all of the trees down, thus clearing the forest, hence the name- clear-cutting. The Trans Amazonian Highway has already opened up large parts of the forest and now a new road is going to be paved, the BR is a road that runs km from Cuiaba to Santarem. More soil and silt is being washed into rivers, resulting in changes to waterways and transport 5. They build roads into the forest, logging firms then go in and take out valuable hard woods such as mahogany and cedar, worth thousands of pounds in richer economies like Europe. This means that untouched tropical forests act as a SINK for carbon. Loggers are interested in all types of wood and therefore cut all of the trees down, thus clearing the forest, hence the name- clear-cutting. Share this:. This deforestation has continued to the present day according to the Sao Paulo Space Research Centre. The government planned to tarmac it making it a superhighway. Environmental research Letters Volume 7 Number 2.

The huge Belo Monte dam started operating in April and will generate over 11, Mw of power. Regardless of how poor farmers get their land, they often are only able to gain a few years of decent crop yields before the poor quality of the soil overwhelms their efforts, and then they are forced to move on to another plot of land.
