MAPEANDO O EFEITO DO DESMATAMENTO NAS CHUVAS UM ESTUDO DE CASO DO ESTADO DO MATO GROSSO

This report by the Climate Policy Initiative/PUC-Rio uses an atmospheric transport model to analyze how deforestation in the Amazon, specifically within the Xingu River Basin, impacts rainfall in the state of Mato Grosso. The study demonstrates that forest areas are critical for maintaining air humidity and that their removal leads to a measurable decrease in precipitation, affecting agriculture, energy production, and urban water supplies.

• Deforestation in the Xingu River Basin region is estimated to reduce the historical average annual precipitation in the state of Mato Grosso by 7%.
• The impact of deforestation on rainfall varies by season: during the rainy season, precipitation could decrease by up to 8% of the historical average, while during the dry season, the reduction could reach 15%.
• Geographic vulnerability to rainfall reduction differs by season: the center and north of Mato Grosso are most affected during the rainy season, whereas the center and northwest are most affected during the dry season.
• The study identifies that the center of Mato Grosso, which contains the most productive agricultural producers, is heavily impacted during both the rainy and dry seasons.
• The northern region of Mato Grosso, home to the Teles Pires Hydroelectric Plant, is among the areas most affected during the rainy season.
• Atmospheric transport patterns show that the rainy season is characterized by winds moving from north to south (from the Amazon), while the dry season is characterized by winds moving from east to west (from outside the Amazon).
• The report notes that the Amazon forest's role in regulating rainfall extends beyond Brazil, affecting precipitation in Argentina and other South American countries.
