Is Amazonian soil leached?

Amazonian soils are also leached but not as deeply. In the terra firme of the rainforest, dead organic matter quickly decays and is recycled. However, once the overlying forest canopy is destroyed—e.g., by clear-cutting or burning—that regenerative cycle is interrupted, and many nutrients and organic matter are lost. More fertile Amazonian soils, interspersed between the zones of leached soil, include várzea alluvial deposits and terra preta dos indios (“black earth of the Indians”), which has developed throughout Amazonia on the sites of prehistoric settlements.

What are the threats to Brazil?

Suzana Bustamante, one of the coordinators of Working Group 3 of the 5th IPCC Report, considers that the greatest threats hanging over Brazil stem from the expected reduction in rainfall in most of the area of food production and capture for hydroelectric and consumption, the country's strategy, both adaptive and mitigating, of investing in reducing deforestation must be a priority for the country, as forests are major producers and conservators of water resources, in addition to all the other essential environmental services they provide and all the biodiversity they harbor. Brazil is the most biodiverse country in the world, an invaluable wealth that is at great risk and is suffering continuous losses.

How will the Amazon biome change?

Brazile's ecosystems will be impacted by temperature changes and rainfall changes. In the projections of the 1st Report, by the end of the 21st century, the Amazon may experience a reduction of up to 45% in rainfall, and an increase in the average temperature of up to 6 °C. This comes close to the worst scenarios foreseen by the Intergovernmental Panel on Climate Change (IPCC), which predicted important changes in most of the biome. However, the impact of deforestation was not considered in the assessment, which will certainly increase the levels of variation to some extent. The evolution of the future scenario will depend on the country's success in managing the serious threats to the biome. After a decade-long trend of reduced deforestation rates, recent years have documented a rapid increase in destruction of trees. A report estimated that if 40% of the forest disappears, droughts will increase and turn much of the forest into savannah. This will result in a drastic reduction in biodiversity and will also have a negative effect on the amount of rain Brazil can expect.

How does wind affect the Amazon rainforest?

Wind circulation and rain production through the Amazon rainforest. Ocean winds penetrate the Amazon, are impregnated with moisture produced by the forest through evaporation, and this moisture is discharged as rain in several regions of Brazil and other South American countries.

How does the Amazon affect the climate?

The Amazon has a prominent role in regulating the climate throughout Brazil and other regions in South America . Its forest is a major carbon sink and is essential for the formation of the rains that irrigate much of the country. According to Marengo et al, 30% to 50% of the rainfall in the Amazon Basin originates in the forest itself through evaporation. "In addition, the humidity originated in the Amazon Basin is carried by the winds to other parts of the continent and is considered important in the formation of precipitation in regions distant from the Amazon itself". Naturally, if the forest disappears, the rains will disappear. A vicious circle is created in which if deforestation exceeds a certain critical level, estimated at around 40% of losses, the forest will be unable to generate enough rain to maintain itself: the less forest, the less precipitation, and the less precipitation, the less forest. About 19% of the Amazon forest has already been lost, and recent studies indicate that it is close to passing the critical point, beyond which its degradation will become irreversible. In addition to the problems in the Amazon, all other national biomes – the Cerrado, the Semi-Arid, the Pantanal, the Atlantic Forest and the Pampa – also suffer important effects, most of them with an increasing tendency, contributing to amplify the cascading effects.
