The Amazon rainforest is likely losing resilience, data analysis from high-resolution satellite images suggests.
The Amazon rainforest is likely losing resilience, data analysis from high-resolution satellite images suggests. This is due to stress from a combination of logging and burning – the influence of human-caused climate change is not clearly determinable so far, but will likely matter greatly in the future. For about three quarters of the forest, the ability to recover from perturbation has been decreasing since the early 2000s, which the scientists see as a warning sign. The new evidence is derived from advanced statistical analysis of satellite data of changes in vegetation biomass.
“Reduced resilience – the ability to recover from perturbations like droughts or fires – can mean an increased risk of dieback of the Amazon rainforest. That we see such a resilience loss in observations is worrying,” says Niklas Boers from the Potsdam Institute for Climate Impact Research and the Technical University of Munich, who conducted the study jointly with researchers from the University of Exeter, UK.
“The Amazon rainforest is a home to a unique host of biodiversity, strongly influences rainfall all over South America by way of its enormous evapotranspiration, and stores huge amounts of carbon that could be released as greenhouse gases in the case of even partial dieback, in turn contributing to further global warming,” Boers explains. “This is why the rainforest is of global relevance.”
