Belém has always been a gateway to the vast Amazon, a city shaped by its proximity to the river and its deep ties to the rainforest. As the first city founded in the Brazilian Amazon, its strategic location made it a centre of trade, culture, and resilience. But like many urban hubs in the region, Belém faces mounting challenges: rapid, unplanned expansion, insufficient resources, and the strain of climate change. These issues are not unique to Belém; they ripple across the Amazon, where 50 million people live, 70% of them in cities.
Determined to turn these challenges into opportunities, Belém took a bold step in August 2023, launching the Amazon Cities Forum. This initiative, uniting 39 cities across the eight nations of the Amazon Cooperation Treaty Organization (ACTO), seeks to redefine urban development in the rainforest.
The goal is ambitious yet urgent: protect the Amazon while ensuring a sustainable future for those who call it home.The timing could not be more critical. With the COP30 climate summit approaching, Amazonian cities have a rare opportunity to assert their role in global climate action. They are not just guardians of the rainforest but also hubs of innovation, where solutions for sustainable urbanization can take root. Recognizing the importance of this effort, the Inter-American Development Bank (IDB) has stepped in, providing financial and technical support to strengthen the Forum’s initiatives over its first biennium.
The Forum is more than a platform for discussion; it is a catalyst for action. It hosts four annual meetings focused on institutional capacity building and knowledge exchange. Beyond that, it is developing a repository of best practices in sustainable urban development and curating a portfolio of bankable projects designed to attract investment. Efforts also extend to disaster risk management strategies and pilot programs that foster climate resilience and innovation.
With growing recognition from regional leaders and strategic partners, the Amazon Cities Forum is forging a new path—one where urban development and rainforest preservation go hand in hand. In this crucial moment, Belém and its allies are proving that cities can be both engines of progress and stewards of the environment, shaping a future where people and nature thrive together.
The Amazon biome, one of the world’s most critical ecosystems, faces increasing threats from deforestation, biodiversity loss, and climate change. Rising temperatures, prolonged droughts, and extreme weather events are accelerating environmental degradation, pushing the region closer to an irreversible tipping point. If the Amazon reaches this threshold, it could lose its ability to regulate climate patterns, with devastating consequences not only for the region but for the entire planet.
At the same time, the majority of the Amazon’s 50 million inhabitants now live in cities, where rapid and unplanned urban expansion is compounding environmental risks. Many urban areas struggle with inadequate infrastructure, weak governance, and limited resources, leaving them highly vulnerable to climate-related disasters such as floods, heatwaves, and water shortages. Without urgent intervention, both the natural environment and the communities that depend on it will face increasingly severe consequences.
Building resilient Amazonian cities is crucial to reversing this trajectory. Strengthening their capacity to adapt to climate change, implement sustainable urban development, and protect the biome is not only a regional necessity but a global imperative.
The Amazon Cities Forum is built on the recognition that urban centres play a fundamental role in protecting the Amazon biome. Its main objective is to develop a collective, long-term strategy for compact, efficient, green, and resilient Amazonian cities. Designed to transcend national borders, this strategy is led by local leaders from the eight countries in the region, ensuring alignment with the specific needs and realities of their communities. At the same time, it is supported by national governments and integrated into global frameworks, promoting multilevel cooperation for effective implementation.
With COP30 set to take place in an Amazonian city for the first time in 2025, the Forum aims to present an initial version of this strategy at the conference, engaging key global actors in its implementation. To meet this objective within a short timeframe, the Forum focuses on three key areas: strengthening the institutional, technical, and financial capacities of Amazonian cities through knowledge exchange and resource mobilization; documenting and sharing successful examples of sustainable urban development; and fostering new solutions to address the region’s climate challenges.
By structuring its work around these priorities, the Forum seeks to position Amazonian cities as central actors in global climate action, ensuring they are equipped to showcase their shared strategy and progress at COP30.
The creation of the Amazon Cities Forum represents a milestone in regional cooperation, serving as the first city-led initiative to bring together representatives from across the Amazon in developing a long-term strategy for sustainable urbanization. By fostering collaboration and shared action, the Forum ensures that urban centres play an active role in protecting the rainforest while building a sustainable and resilient future for the millions who depend on it.
By consolidating knowledge and fostering multi-level coordination, the Forum serves as a dynamic platform to confront the unique challenges faced by Amazonian cities head-on. Its official recognition by the Presidents of the Amazon Cooperation Treaty Organization (ACTO) and its inclusion in MINURVI’s inaugural permanent working group underline its vital role in shaping urban policies for the region.
Beyond governance, the Forum has catalysed multisectoral collaboration, driving various organizations to pool their resources, expertise, and efforts toward a unified vision for sustainable development.
Non-governmental organizations (NGOs), research institutes, and specialists focused on Amazonian and urban issues have been instrumental in this initiative, as members of the Forum’s Technical Advisory Council.
This powerful coalition enhances knowledge exchange and accelerates international co-investment, positioning the Amazon as a central hub for global and regional partnerships dedicated to sustainable urban transformation.
The Forum’s influence is already making waves on the international stage. At COP28, it provided a prominent platform for Amazonian perspectives, and with an ambitious work plan, it is set to amplify these voices even further at COP30.
By establishing a common agenda, this initiative guarantees that the outcomes of the conference resonate far beyond Belém, effectively representing the collective interests of all Amazonian cities and solidifying their significant role in global climate action. Beyond immediate challenges, this initiative contributes to the long-term sustainability and resilience of cities across the Amazon region.
