Belem, host of next year's climate talks, is Amazonian city plagued with pollution and violence

BELEM, Brazil (AP) — For the last few years, climate scientists, environmentalists and Brazilian President Luiz Inacio Lula da Silva have been talking up the first U.N. climate conference to be held in the Amazon. The largest tropical forest in the world stores huge amounts of planet-warming greenhouse gases, making it crucial in the world's fight against climate change.

In addition to the symbolism of hosting in the Amazon, COP30, as the climate talks are called, will be a pivotal gathering because nations must come with updated plans to reduce emissions.

But when tens of thousands of participants arrive in the host city of Belem next year, they won’t find idyllic images of rainforest, like lush vegetation and clean rivers. In Belem, impoverished, crime-ridden and filled with inequalities, most of the 2.5 million residents live in slums. What's more, only 2% of the city's sewage gets treated, imposing a heavy toll on its 14 river basins.

Since it was designated host two years ago, this bustling metropolitan area near the Amazon River has been racing to prepare. In several parts of the city, construction hoardings bearing “COP30” signs surround buildings. Three major hotels are under development, but that won't provide enough rooms, so organizers plan to get cruise ships that can house up to 5,000 people. Brazil's government estimates that 50,000 people will attend COP30, including up to 150 heads of state.

COP30 will also serve as a test for Lula’s commitment to preserving the Amazon. When he was elected for a third term in 2022, the leftist leader was celebrated for promises to curb the explosion of deforestation that occurred during the far-right government of President Jair Bolsonaro.

While Lula's administration has sharply reduced the rate of forest destruction, the Brazilian leader has made statements in favor of two of the most controversial projects in the region: opening the mouth of the Amazon River for large oil exploration and paving a highway that cuts through the most preserved section of the rainforest.

Infrastructure and security preparations in historically violent city

The state government of Para has launched some 30 infrastructure projects that range from tourism to urban development.

One of the largest is Parque da Cidade, or City Park, spanning 500,000 square meters (123 acres) atop a former airfield. It will feature a museum, restaurants and walking and cycling trails. After serving as a venue for COP, it will become a public space.

The project is being carried out by mining giant Vale, responsible for two of Brazil’s most devastating environmental disasters, in 2015 and 2019, when waste dams collapsed in Minas Gerais state, killing 291 people and contaminating hundreds of miles of waterways.
