What's being done to save the Amazon rainforest? - What in the World podcast, BBC World Service

Key Concepts

• Amazon Rainforest: World's largest tropical rainforest, spanning 6 million km², home to immense biodiversity and 47 million people, including 2 million indigenous.
• Biodiversity: The Amazon is the most biodiverse place on Earth, with an estimated 16,000 tree species, many yet to be described, potentially holding medicinal and cosmetic value.
• Climate Regulation: The Amazon plays a crucial role in global climate by absorbing CO2, acting as a "brake" on climate change, and generating rainfall that irrigates regions as far as Texas and Argentina.
• Deforestation Drivers: Cattle ranching is the primary driver, followed by illegal mining and logging. Climate change exacerbates these issues by increasing temperatures and reducing rainfall, leading to drier conditions and increased fire risk.
• Economic Importance: The Amazon is a source of valuable resources like gold, timber, rubber, coffee, and medicinal plants, and is also a source of income for its inhabitants, leading to a conflict between development and conservation.
• Cop30: The upcoming climate summit in Belém, Brazil, will focus on the Amazon and climate finance.
• Tropical Forests Forever (TFFF) Facility: A proposed financial mechanism led by Brazil to compensate countries for forest preservation, with 20% allocated to indigenous peoples.
• Paris Agreement: A 2015 global agreement aiming to limit global warming to 1.5 degrees Celsius above pre-industrial levels, crucial for Amazonian preservation.

The Amazon's Immense Scale and Biodiversity

The Amazon rainforest is described as being incredibly vast, covering 6 million square kilometers, which is equivalent to three times the size of Mexico. This immense area is home to an extraordinary amount of forest and a rich diversity of animal species. Hannah, the host, highlights that the Amazon is the most biodiverse place on Earth. Dr. Erika Berenguer, a senior researcher at Oxford University, elaborates on this, stating that the Amazon basin, which spans nine countries, is estimated to have around 16,000 species of trees, with 11,000 already described by scientists. She notes that many of these plants may hold undiscovered potential for medicine and cosmetics. The sheer volume of life is overwhelming to the senses, with constant insect buzzing, birds, and diverse shades of green trees.

Global Importance of the Amazon

The Amazon's significance extends far beyond its geographical boundaries. It generates substantial rainfall that irrigates agricultural fields as far north as Texas and as far south as the La Plata Basin in Argentina and Uruguay. Furthermore, the Amazon stores a massive amount of carbon in its trees. If completely deforested and burned, the released CO2 would be equivalent to 15 to 20 years of global greenhouse gas emissions, making it impossible to stay below the 1.5-degree Celsius temperature increase target set by the Paris Agreement.

Regional and Global Climate Regulation

Graihagh Jackson explains the Amazon's role in regional and global climate regulation. Regionally, the sun's heat causes water to evaporate and transpire from trees, forming "flying rivers" that transport moisture across the continent, bringing rain to distant areas. This rainfall is vital for agriculture and for hydropower in countries like Brazil. Globally, the Amazon acts as a "brake" on climate change by absorbing carbon dioxide (CO2) from the atmosphere. Trees use CO2 to create energy, storing it in their branches, leaves, and soil. This process removes CO2, which would otherwise act as a heat-trapping blanket, thus preventing a much hotter world.

Valuable Resources and Economic Development

The Amazon is a treasure trove of valuable resources. Beyond gold and timber, it provides rubber, coffee, and numerous medicinal compounds. Quinine, used for centuries to treat malaria, is derived from tree bark. Fishing is also a significant economic activity. However, this abundance also presents a challenge: many of the 47 million people living in the Amazon, including 2 million indigenous individuals, live below the poverty line. They view the forest as a source of income and a means to escape poverty, leading to a complex tension between conservation efforts and the desire for economic development.

Threats to the Amazon: Deforestation and Climate Change

Scientists are warning that the Amazon is at risk of disappearing. The primary driver of tropical deforestation globally is cattle ranching, which accounts for beef products and leather. Illegal activities like mining and logging also contribute significantly, exacerbated by the vastness and remoteness of the region, making enforcement difficult. Compounding these issues is climate change, which is increasing temperatures and reducing rainfall in the Amazon. This creates a "double whammy" effect: deforestation leads to drier conditions, and climate change intensifies this dryness. The forest floor, typically wet leaf litter, is becoming tinder-like, making fires spread rapidly and easily. Data from 2001 to 2023 shows that fires in the Amazon region are burning at least twice as much as in the early 2000s, with 2024 being a record-breaking year.

Efforts to Protect the Amazon and Climate Finance

In response to these threats, a global agreement was signed in 2021 by over 100 world leaders to end deforestation by 2030. Several Amazonian countries, including Peru, Brazil, Ecuador, Guyana, and Suriname, pledged to this goal. However, Colombia, Bolivia, French Guiana, and Venezuela did not sign, with Venezuela and Bolivia expressing a desire to develop the forest. This highlights the difficult balance between protecting the environment and supporting the livelihoods of those living within it.

Addressing forest fires requires tackling emissions and removing CO2 from the atmosphere to cool the planet. This raises the question of who should bear the cost. Historically, wealthy Western countries have been the largest polluters. Therefore, countries like Brazil argue that these nations should fund Amazon preservation and compensate for damages. This is why climate summits, like the upcoming Cop30, are increasingly focused on climate finance and its equitable distribution.

Cop30 and the Tropical Forests Forever Facility

Cop30, the International Summit on Climate Change, will be held in the Amazon for the first time, with a specific focus on the region. A key initiative expected to be discussed is the Tropical Forests Forever (TFFF) facility, a financial mechanism led by Brazil. The TFFF aims to compensate countries for preserving their forests, with a notable provision that 20% of the funds will be allocated to indigenous peoples, recognizing their crucial role in protecting biodiversity and stored carbon.

Conclusion: A Shared Responsibility

The Amazon's importance for biodiversity, climate regulation, and resource provision is undeniable. However, it faces severe threats from deforestation and climate change. While global agreements and financial mechanisms like the TFFF are being developed, the ultimate responsibility for protecting the Amazon, and by extension, the planet, lies with everyone. Reducing emissions, as agreed upon in the Paris Agreement to limit warming to 1.5 degrees Celsius, is crucial for mitigating forest fires and preserving this vital ecosystem. The podcast emphasizes that this is a collective effort, and individuals play a role in reducing their emissions.
