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

This report by CPI/PUC-Rio uses an atmospheric transport model to demonstrate that deforestation in the Amazon rainforest reduces rainfall in Mato Grosso. A counterfactual analysis of the total deforestation of indigenous territories in the Xingu River Basin suggests a 7% reduction in average annual precipitation, with more severe impacts during the dry season. The study highlights the critical role of protected forest areas in sustaining agricultural productivity, hydroelectric power generation, 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: the rainy season may see a reduction of up to 8% of the historical average, while the dry season could experience a reduction of up to 15%.
• Geographic vulnerability to rainfall reduction differs by region and season: the center and north of the state are most affected during the rainy season, while the center and northwest are most affected during the dry season.
• The reduction in rainfall resulting from deforestation threatens key economic sectors in Mato Grosso, specifically agricultural productivity, urban water supply, and the reservoirs of hydroelectric plants.
• Atmospheric transport patterns show that the rainy season is characterized by winds moving from north to south (from the Amazon), whereas the dry season is characterized by east-to-west trajectories from outside the Amazon.
• The study notes that the Amazon forest's role in regulating rainfall extends beyond Brazil, affecting precipitation in Argentina and other South American countries.
