Amazon River Basin

Though this forest stands in South America, the Amazon has a unique global reach as a critical climate stabilizer.

Amazon River Basin

This forest holds 150 billion metric tons of carbon. But deforestation and climate change are reducing its capacity and increasing emissions. We plant trees here because our global health depends on it. 

Because of its immense carbon storage, this forest plays a significant role in stabilizing the global climate. Losing trees here could cause devastating warming. That’s why we’re focused on stopping deforestation and planting trees in this critical area to preserve environmental balance.

Sealing away carbon

Carbon in the atmosphere is the primary contributor to climate change. Trees pull carbon from the air and store it in their leaves, trunks, roots, and soil. In the Amazon River Basin, trees store more than 150 billion metric tons of carbon. That’s the equivalent of 15 to 20 years’ worth of global fossil fuel emissions.

Slowing climate change

When trees are lost or deforested, the carbon they held onto is released as they decompose. That carbon then traps heat in the atmosphere and warms the planet. Losing this forest would add more than 150 billion metric tons of carbon into the atmosphere and cause dangerous global warming. We need to plant to counteract the emissions of deforestation, and “sink” even more carbon.

Anchoring local climate

The forest in this region creates its own weather and produces enough moisture to generate most local rainfall. While full forest loss would be dangerous for the entire planet, the local community would see catastrophic warming and rainfall decline by up to 30%. Trees can simultaneously protect daily life locally and protect future generations globally.

Sustaining a critical watershed

Globally, the demand for freshwater will outstrip supply by 40% by the end of the decade. That’s why we need to preserve the Amazon Rainforest, where one-fifth of the world’s freshwater supply is produced. Planting trees helps the critical water supply stay intact.

Sheltering rare species

This forest houses 10% of the world’s known wildlife species. It’s an unmatched hotspot for biodiversity — and it’s not just about animals either. Several medications have been derived from plant species discovered in the Amazon, including the first effective treatment for malaria. Planting trees here can help protect this delicate habitat.

Empowering local land stewards

About 385 Indigenous groups live within the Amazon and research proves they are effectively managing and stewarding the forest. The land is culturally significant to Indigenous people and forests provide them crucial resources like food, water, and a means of income.

Current State

The Amazon has already lost 17% of its original tree cover. Scientific models indicate that if 40% of trees are lost, the forest will reach its “tipping point” and the land will naturally — and quickly — transition to a savanna grassland. Without significant reforestation, some parts of the Amazon could collapse by 2050.  

That’s why the Arbor Day Foundation is working urgently across eight South American countries to protect and grow the forest in the Amazon River Basin.

Our Work in the Amazon River Basin

We’ve made the Amazon River Basin one of our priority areas for reforestation because we understand how important this region is in the context of global health. We’ve already committed to planting more than 1.4 million trees here, with a focus on using those trees to create income opportunities for local residents. We prioritize engaging Indigenous and local communities to be part of the reforestation process to ensure the forest stays standing for many years to come.

Right Trees, Right Place, Right Reason

As a global nonprofit dedicated to planting trees, the Arbor Day Foundation is committed to nurturing crucial forestlands. We leverage cutting-edge science and data to identify ecosystems of global influence, like the Amazon River Basin. We use our exclusive forest priority index to elevate our impact through reforestation and mobilize our network of partners to help plant at the speed of a changing world.
