Forest removal costs Brazilian farmers losses of one billion dollars

Contracts of corn and Brazil soybean production turned into an agricultural force, and this was the result of the destruction of vast areas of the Amazon rain forests, and this led to a long -term disagreement between farmers and environmental defenders. But a study was published last October by the University of Minas Gerais in Brazil, and the Norwegian rainforesting Foundation showing the extent of damage that the removal of forests with farmers as well.

The report shows that the continued cutting of trees and the removal of all trees from a specific area, in the Brazilian Amazon region, resulted in a decrease in crop production, which led to total economic losses of about one billion dollars between 2006 and 2019. After calculating production costs, net revenues for soybeans decreased by 10% during that period, while corn revenues decreased by 20%. “These results clarify the danger posed by the removal of forests on global food security,” said Andros Krag, a specialist in the Norway Forestry Foundation in Norway.

Tree breathing

And when the old forests turn into agricultural plains, the exact balance of the water cycle is disrupted. With the breathing of trees, the water turns into vapor, which continues to form large and dense rainy clouds, and has a cooling effect on the area. This moisture recycling process also affects the air cycle, which plays a major role in regulating temperature in the Amazon Basin.

The effects of this seem more clear in most of the areas where the trees were cut, and the delay in the start of the rainy season for 76 days, since 1980, in the areas where more than 80% of the forests have been removed.

The rate of rainfall in the same regions decreased by 40% in the soybean transplant season, and 23% in the corn transplant season in the period from 1999 to 2019. The maximum temperatures of the air increased by about 2.5 degrees Celsius during the same period, from 30 ° C to 32.5 Celsius, and of course, low rainfall and high temperatures will lead to less harvest and crops.

Preventing more tree cutting in southern Amazon can lead to reducing these changes that have been mentioned, and if the trees continue at a rapid pace, farmers of all spectra, including livestock, will face more harsh conditions, and one estimates indicate that they will lose by general solutions 2050 is up to one billion dollars annually.

Reducing changes

Planting more trees can help reduce rainfall changes. The report concluded that in the Brazilian state of Baraa, which is considered a center for intense agriculture, trees have been re -transplanted in 55 thousand square kilometers of agricultural lands, and for this the rain may come on average five days early, and up to 19 days in some areas. In some areas, which have been exposed to the most cut of trees, this can bring more steam at a rate of 155 millimeters annually.

But at the present time, this is very difficult, as agricultural companies in Brazil tend to deal with such reports and researchers who write them, with a degree of suspicion and suspicion, and the term “agricultural fear” is often used to describe scientists who criticize agricultural practices in the country.

Ordinary people also tend to doubt, and despite the increasing costs of adapting to the dry conditions, the Brazilian farmers reject allegations that the decrease in “yield” is due to climate change or the removal of forests.

The researcher and the main participant in writing the report hopes that the focus on the financial effects of the process of cutting trees, not the abstract models resulting from them, can persuade the critics, and claims that sustainable agriculture practices serve the economic interests of agricultural work. He said, “They say that we are guilty of the phobia of agriculture, but they commit suicide agriculturally.” About “Economist”
