Climate change threatens nature’s balance in Brazil’s watery Pantanal

By Gerry Hadden

When you think of Brazil and nature, the massive Amazon is most likely the first thing that comes to mind. After all, the largest rainforest on the planet acts as the “lungs of the earth.”

The Amazon is mythical and mysterious, and its ongoing destruction is well-documented.

But if someone were to ask, “What about The Pantanal?” you could be forgiven for shrugging your shoulders.

And yet Brazil’s Pantanal is no less important than the better-known jungle to the north. It’s the largest tropical wetlands on Earth. Depending on how you measure it, its watery grasslands and forests cover between 54,000 and 75,000 square miles. It rivals the Amazon in biodiversity and beauty. But waterways don’t capture the imagination the way jungles do. So when the Pantanal comes under threat we’re less likely to hear about it and less likely to understand the alarming potential consequences.

The Pantanal is shrinking. It’s losing ground to rising temperatures and to the same kind of logging and development that’s devastating the Amazon next door. A consequence of that deforestation is less humidity, evaporation and rain — rain that normally heads south and keeps the Pantanal flooded. As the Pantanal dries out, more and more wildfires burn out of control, creating a vicious cycle.

The blazes, mainly started by people, are wiping out the unique flora and fauna that have evolved within the Pantanal’s ecosystem over centuries. From capybara — the world’s largest rodent — to jaguars, caiman and countless bird species.

Watch “The Forever Fires,” a film by Gerry Hadden and Armando Guerra.

Who’ll defend a swamp?

There are locals, biologists and veterinarians who defend the Pantanal, but they’ve learned that a global campaign to save a swamp won’t gain traction.

Still, they try. Tour guide Ailtan Lara, who owns a guest lodge deep in the Pantanal, doesn’t just take his guests for joy rides in his motorized launch. He wants them to catch a glimpse of the largest feline predator in the western hemisphere: the South American jaguar. The jaguar’s majesty, up close, is unforgettable. Its role as an alpha predator in the Pantanal ecosystem is key to maintaining the balance of almost every species in the wetlands’ complex food chain.

Lara speeds around, tracking and maintaining a database of the jaguars, animals he can identify by the unique spots on their faces. He gives them names, and he sends tourists home with photos they’re sure to share with the larger world.

Interest in jaguars, he says, is what gives him hope that public pressure will grow and his government will step in at some point to stop the destruction of his Pantanal homeland, and of the larger Amazon rainforest. After all, one ecosystem cannot live without the other.

It will be catastrophic for humans in Brazil and beyond if they both go.

Fighting for wildlife

Wildlife veterinarian Carla Sassi shares Lara’s passion for the Pantanal. Since the record wildfires in the Pantanal in 2020, she’s made several visits to treat burned animals and to assess the risk fires pose for the region’s diverse wildlife.

And, like Lara, Sassi’s work puts a face on what’s at stake. She hopes humanity will be moved into action by stories about the Pantanal’s buffalo, deer, birds and even snakes, amid the unfolding tragedy.

By all accounts, the 11th hour has already arrived in the Pantanal.
