Com o objetivo de refletir sobre as causas que levaram ao desmatamento e estimular reação por parte do Poder Público brasileiro, o Instituto de Pesquisa Ambiental da Amazônia (IPAM), o Instituto Socioambiental (ISA) e o Instituto do Homem e Meio Ambiente da Amazônia (IMAZON) apresentam neste documento reflexões sobre o aumento do desmatamento ocorrido em 2013 e elencam uma série de recomendações para a redução nas taxas de destruição da floresta amazônica.

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.
