An unprecedented study pointed out that a quarter of the rainfall in the South and Southeast regions of Brazil comes from the Amazon region.
In an interview with CNN Radio professor at the Institute of Physics at USP Henrique Barbosa explained that a tactic called a “complex network” was used to understand what happens in the Amazon.
The practice of physics understands the world in several ways, such as understanding how information is transmitted through the brain’s network of neurons, for example.
Or even, according to the expert, how the electrical network transmits power from one point to another.
“We started to think of the Amazon forest and the atmosphere as a complex network, which transports water from one place to another, to understand how the moisture it receives from the ocean and how it reaches other regions of Brazil.”
The professor highlighted that the study showed that for every tree in the Amazon that must die due to human effects – such as deforestation and climatic effects – one more will die without human action, as a consequence of the forest being removed.
“Moisture recycling is very important, much of the rain is returned by the forest back to the atmosphere, evaporates or is transpired back, it is an important contribution.”
Preservation
Henrique Barbosa, however, affirmed that the study is not a “lime shovel” about the future of the Amazon, on the contrary, because it points out which regions of the forest suffer the most from drought and human action.
“What we have to do is preserve the Amazon, not only for its heritage, but for the ecosystem services it provides, to export water to other regions that depend on it for agricultural production.”
According to the professor, “there is still time” to reverse the situation, but action must be taken as soon as possible.
