O combate efetivo ao fogo na Amazônia é normalmente limitado pela falta de recursos e informações precisas sobre onde o risco é maior. Nesse sentido, combinando dados de satélite sobre desmatamento passado e fogo com análises climáticas, determinamos áreas com o risco mais alto de queimada (tons escuros no mapa) durante a temporada de fogo de 2021, cuja fase mais crítica começa em julho e dura por volta de quatro meses.

Threshold Responses to Soil Moisture Deficit by Trees and Soil in Tropical Rain Forests: Insights from Field Experiments
Many tropical rain forest regions are at risk of increased future drought. The net effects of drought on forest ecosystem functioning will be substantial if important ecological thresholds are passed. However, understanding and predicting these effects is challenging using observational studies alone. Field-based rainfall exclusion (canopy throughfall exclusion; TFE) experiments can offer mechanistic insight into the response to extended or severe drought and can be used to help improve model-based simulations, which are currently inadequate.
