Pantanal waterway project would destroy a 'paradise on Earth', scientists warn

Dozens of scientists are sounding the alarm that carving a commercial waterway through the world’s largest wetlands could spell the “end of an entire biome”, and leave hundreds of thousands of hectares of land to be devastated by wildfires.

The Pantanal wetland – which falls within Brazil, Bolivia and Paraguay, covering an area almost half the size of Germany – is facing the proposed construction of a commercial waterway, as well as the expansion of industrial farming and spread of intense wildfires. A cohort of 40 scientists say the waterway development represents an existential threat to the ecosystem: reducing the floodplain, increasing the risk of fires and transforming the area into a landscape that could more easily be farmed.

“If the hidrovia project goes ahead, navigation of large train barges in the Pantanal, with dredging in critical reaches of the Paraguay River, will probably mean the end of the Pantanal as we know it,” said Pierre Girard from the Federal University of Mato Grosso and Pantanal Research Center. “Reducing the annually flooded area, [coupled] with climate change and increased pressure on land use in the biome will increase the risks of destructive fires like the catastrophic ones seen in 2020 [when nearly a fifth of the area burned].”
