- Millions of people across the region still lack reliable access to transport, electricity, water, and digital services, particularly in remote and sparsely populated areas.
- Conventional infrastructure models often fail in this context, as they are costly, vulnerable to natural disasters, and can accelerate environmental degradation.
- Innovative solutions — ranging from decentralized energy systems to fluvial transport and digital connectivity — combined with stronger institutions and coordination, can improve access while safeguarding ecosystems.
Despite significant investments in recent decades, people in Amazonia still have less access to infrastructure services than populations in other parts of their countries. Sparsely populated areas and poorly connected populations make traditional infrastructure solutions prohibitively expensive and potentially environmentally unsustainable if not managed adequately.
Infrastructure gaps have effects on people’s everyday lives. About 7.1 million people live more than 45 minutes from a primary road, and 4.7 million are similarly distant from a secondary road. In rural Amazonia, 4.3 million people lack reliable electricity, and in nearly 30% of the territory, household drinking water access is below 43%.
Addressing these challenges requires rethinking how infrastructure is planned and delivered in the region. Drawing on our latest publication, this analysis reviews the current state of infrastructure in Amazonia, outlines the challenges to increasing effective access, and discusses what can be done about them.
Amazonia’s road network has expanded by 55% over the last two decades, reaching about 145,000 kilometers. The share of paved roads has also increased, rising from 32% to 45%. Despite this growth, connectivity across the region remains highly fragmented, in part because many new roads are not designed to improve population connectivity. Official roads, intended for national or regional connectivity, account for only 15–28% of the network. The rest are unofficial roads, often built by private actors for resource extraction or illegal activities. These unofficial roads are a major driver of deforestation, as they open up remote areas to logging, cattle ranching, mining, and land grabbing.
Fragmented connectivity restricts access to essential services; however, expanding connectivity through traditional infrastructure can entail substantial environmental damage. Waterways offer a context-based and more environmentally sustainable alternative, as 51% of Amazonia is naturally connected to river networks, yet this potential remains underutilized. In northern Brazil, although inland water transport accounts for 90% of cargo movement and 30% of urban communities in Amazonas are accessible only by boat, only 6,500 kilometers of the over 20,000 kilometers of navigable rivers are used for regular shipping, and many remote areas lack adequate port facilities. Infrastructure resilience is critical for this type of infrastructure, since recent severe droughts have disrupted navigation, further isolating communities and limiting access to food, fuel, and healthcare.
Electricity access is another challenge in the region. As of 2020, more than 350 dams operated in Amazonia, providing 55% of the total installed capacity across Brazil, Bolivia, Colombia, Ecuador, and Peru. Hundreds more are planned (Figure 1), but at least 10% are in protected areas and over 5% in Indigenous territories, raising concerns about ecosystem disruption and displacement. While Amazonia has an abundance of dam-derived energy, not all dams in the region serve the interests of local communities.
Even in areas with high population density, digital connectivity is limited: only 8% of Amazonia has high-speed internet service that matches its population density, constraining access to essential services such as telehealth, remote education, and job search opportunities.
Sanitation and water access are also uneven. In some rural departments, only 9% of households have access to sanitation, and in nearly 30% of the territory, household drinking water access is below 43%. These gaps affect 11.2 million people. Access to sanitation and drinking water in Colombia’s Amazonia is 30% below the national average; in Peru, it is 20% below.
Delivering infrastructure through conventional approaches, such as expanding electric and digital grids, pipelines, and highways, is often prohibitively expensive for small, remote communities, whether from a technical, financial, or environmental perspective. These solutions are also vulnerable to natural disasters such as droughts, floods, and wildfires, which can damage assets and disrupt services.
The environmental impact of infrastructure can be profound. About 95% of deforestation in Brazil’s Amazonia occurs within 5 km of a road or 1 km of a navigable river. Unofficial roads enable illegal logging, cattle grazing, and land grabbing, creating a cycle of exploitation and abandonment. Hydroelectric dams, while providing renewable energy, can cause flooding, disrupt ecosystems, and have transboundary impacts.
Poor planning and weak regulatory oversight have resulted in incomplete projects. Coordination between national and subnational authorities, particularly in transboundary or regional initiatives, is often insufficient. Moreover, limited consultation with local communities further undermines infrastructure outcomes.
Effective infrastructure development depends on strong governance and well-defined property rights frameworks. Transparency and clarity in land tenure are also essential, as unclear property rights have contributed to land grabbing and social conflict.
To address these challenges, Amazonia needs a new approach to infrastructure, one that is context-driven, inclusive, and sustainable. Key priorities include:
• Promoting decentralized, context-based, and resilient infrastructure solutions. The challenges of traditional infrastructure highlight the need for innovative, resilient, and decentralized solutions. For example, water cisterns distributed in Brazil have provided clean water during dry seasons and reduced poverty. Decentralized solar mini-grids are being deployed in Suriname to bring electricity to isolated villages. Electrified fluvial transport, such as solar-powered boats in Ecuador and Brazil, is improving mobility while reducing emissions. Similarly, subfluvial fiber-optic cables installed along navigable waterways are expanding digital connectivity by leveraging the region’s natural river-based connectivity.
• Scaling up sustainable and resilient infrastructure. Strengthening redundancy can improve resilience and ensure continued access during extreme weather events, while adopting standards that minimize socio-environmental impacts and promote ecosystem-based solutions is essential.
• Boosting institutional capacity and coordination. Developing cross-jurisdictional infrastructure maps, ensuring early involvement across all levels of government (national, regional, and municipal), and strengthening regional mechanisms such as ACTO can help harmonize standards, improve transboundary and regional planning, and facilitate joint investment. Digital procurement platforms can enhance transparency and reduce corruption, but they must be accompanied by capacity building and effective enforcement. Strengthening cadastral information systems and clarifying property rights are also essential steps toward improved land governance.
• Ensuring meaningful consultation and participation. Infrastructure projects must involve local communities, Indigenous Peoples, and civil society from the outset to ensure legitimacy and sustainability.
In Amazonia, the path to better infrastructure will require rethinking how infrastructure is planned and delivered. Context-based, resilient, and decentralized solutions, supported by strong institutions, regional coordination, and meaningful community participation, can help expand access while protecting ecosystems and improving livelihoods.
