In Manaus, sewer lines and battery plants show why Amazon development cannot be separated from dignity, jobs, and climate survival, as EFE reports. Sustainable investment is becoming a test of whether Brazil can protect forests by protecting its own people.
The Amazon Needs More Than Promises
The Amazon is often described from afar as a canopy, a carbon sink, a river, and an emergency. But in Manaus, Brazil’s largest city in the forest, the argument is becoming more uncomfortable and more human. If the region is going to defend nature, it must also defend the people who live in it.
That is the central tension running through an EFE report from Manaus, where projects as different as a sewage system in one of the city’s poorest neighborhoods and the expansion of a battery plant employing hundreds of people are being presented as examples of what sustainable investment can mean in practice. Not a speech. Not a slogan. Pipes, jobs, health insurance, cleaner production, and a chance to keep development from being treated as the enemy of the forest.
The Amazon is home to 50 million inhabitants, according to the notes, and remains one of Latin America’s least socially developed regions. That fact should change how the climate conversation is framed. Deforestation is not only driven by greed or illegality, though both matter. It is also fed by abandonment, a lack of infrastructure, few stable livelihoods, and an outdated development model that leaves poor families to choose between survival and conservation.
Manaus wants to position itself at the front of sustainable solutions, balancing economic opportunity for its more than two million residents with respect for the surrounding environment. That ambition is being highlighted during Sustainability Week, organized by IDB Invest, the financial arm of the Inter-American Development Bank. The message is direct: sustainable investments in the region must be increased and scaled up.
For Brazil, the stakes are national and symbolic. The Amazon is a global climate shield, but it is also an urban, industrial, and working-class reality. A city cannot be asked to carry planetary responsibility while parts of its population still live without basic sanitation.
Sewage as Climate Policy
In the Beco Nonato neighborhood, around 100 families living in wooden houses on stilts over a river, known as palafitos, lacked a sewage system until recently. The absence of infrastructure meant residents dumped waste into the river, worsening flooding during the rainy season and producing a stench that entered daily life with no invitation.
“It was unbearable, especially during meals. We were ashamed to have people over,” community leader Gisele Dantas, 44, told EFE.
That sentence says more about sustainable development than many glossy climate brochures. Shame over receiving visitors. Meals are interrupted by the smell of untreated waste. A river turned into the final stop for a public service the neighborhood never received. Environmental damage here is not abstract. It comes through the floorboards.
After years of neglect, Beco Nonato was included in Aguas de Manaus’ expansion plans for the sewage network, which aim to achieve universal basic sanitation by 2033 with support from IDB Invest. The bank plans to invest 750 million reais, about $138 million, of the nearly 3 billion reais that Aguas de Manaus needs, and help secure support from other financial entities.
“The primary goal is to reach the 1.8 million people in the city who lack sewage services,” Juan Parodi, lead investment officer and head of the Amazon Initiative at IDB Invest, told EFE.
This is where the Amazon development debate becomes sharper. Basic sanitation is usually treated as a social service rather than a climate strategy. But in Manaus, the two are linked. Sewage infrastructure protects rivers, reduces disease risk, improves dignity, and helps make urban life less destructive to the surrounding ecosystem. It also signals that conservation cannot be built on the humiliation of the poor.
Latin America knows this pattern well. Peripheral neighborhoods are often asked to endure what formal cities hide: contaminated water, unstable housing, flooding, bad smells, long commutes, fragile work, and promises that arrive years late. When those communities are in the Amazon, their exclusion becomes part of a wider ecological crisis.
If Brazil wants to slow deforestation, it cannot rely solely on policing the forest edge. It must invest in the cities that shape the region’s economy and absorb its inequalities. Otherwise, the forest remains surrounded by a development model that produces pressure from every side.
Jobs Can Also Defend Trees
The second example in the EFE report comes from a very different place: a battery factory. UCB Power, based in Manaus, employs 600 people, most of them in the Amazon, and is working toward approval of a financing agreement with IDB Invest. With a loan of around 170 million reais, or $32 million, the company expects to expand and increase its workforce by 30%, Vice President of Operations Antonio Maldonado told EFE.
“Our goal is to improve the future for people here, offering benefits such as health insurance not just for the employee, but for the entire family, extending the benefit to the people of the Amazon region,” Maldonado told EFE during a tour of the battery factory.
The significance is not only that a company is growing. It is that clean energy production, decent employment, and family benefits are being connected within the Amazon rather than imported from elsewhere. Too often, the region is imagined as either untouched wilderness or exploited frontier. This project suggests another possibility: industrial capacity that gives workers a stake in a lower-carbon economy.
Parodi told EFE that such investments are especially attractive to IDB Invest because their impact is spread across several areas, creating jobs and developing the clean energy sector, with positive global effects on carbon dioxide reduction. The idea is to make the Amazon a place where climate solutions are produced, not merely protected from human activity.
A similar example is the project between IDB Invest and DFC, which co-invested $23 million in the micro-mobility platform Tembici to support the expansion of shared bicycle services in Argentina, Brazil, Chile, and Colombia. The assembly plant in Manaus is expected to produce more than 50,000 new bicycles between 2023 and 2029.
That matters because sustainable investment becomes politically stronger when people can touch it. A bike assembled in Manaus. A battery plant is hiring local workers. A sewage line is reaching a neglected neighborhood. These are not perfect answers to Amazon’s many crises, but they are concrete. They turn climate policy into something less distant than a summit stage.
Still, the model will depend on scale and fairness. Sustainable projects cannot become isolated showcases in a region marked by deep social need. If investment only reaches a few visible examples, the old pressures will remain. Illegal clearing, precarious work, informal settlements, and poor infrastructure will continue to push people toward short-term survival.
The deeper lesson from Manaus is that the forest cannot be saved against its people. It has to be saved with them. Brazil’s challenge is to prove that development in the Amazon can mean sewage rather than waste in the river, factories tied to cleaner technologies rather than extractive ruin, and jobs that keep families rooted without making destruction the price of income.
The Amazon has been treated for too long as a sacrifice zone, a treasure chest, a frontier, or a global lung. In Manaus, EFE’s report shows another truth rising from the riverbanks and factory floors: it is also a home. Any serious future for Brazil’s forest begins there.
