A larger part of the Amazon rainforest than previously believed is at risk of crossing a tipping point at which it would become a savanna-type ecosystem, according to new research. The study, based on computer models and data analysis, is published in the journal Nature Communications.

Rainforests are sensitive to changes that affect rainfall for extended periods. If rainfall drops below a certain threshold, areas may shift into a savanna state.

“In around 40 percent of the Amazon, the rainfall is now at a level where the forest could exist in either state—rainforest or savanna, according to our findings,” says lead author Arie Staal, formerly a postdoctoral researcher at the Stockholm Resilience Center and the Copernicus Institute of Utrecht University.

The conclusions are concerning because parts of the Amazon region are currently receiving less rain than they were previously, and this trend is expected to

Bloomberg hosted an exclusive virtual roundtable with over 30 C-suite executives in Asia to discuss the future of data ecosystems with Kenny Lam, CEO of Two Sigma Asia Pacific and Alan Lau, Chairman and CEO of Tencent WeSure.


Challenges in the data ecosystem

Speaking about the challenges in the data ecosystem unique to Asia, Lam said that there is a copious amount of data in the region, but not all data is useful and a lot of effort is spent to identify and make the data useful. “Nine out of ten times, you can’t use the data because of the way data is stored, and it’s impossible to go back in time to find another way to store it,” said Lam. Rather than just
