Since its inception, the Science Panel for the Amazon (SPA) has produced a wide range of impactful publications, including the groundbreaking 2021 Amazon Assessment Report, 18 Policy Briefs, 8 statements, and numerous other materials. These publications have been presented at key regional and global policy forums, such as the UNFCCC COPs, CBD COPs, UN General Assembly (UNGA), High-Level Political Forum (HLPF), and more, contributing to critical discussions on the future of the Amazon.
Amazon Assessment Report 2025
Connectivity of the Amazon for a Living Planet
The Science Panel for the Amazon (SPA) launched its second Amazon Assessment Report at COP30 in Belém.
This new report brings together the latest scientific knowledge and insights with a central focus on Amazonian connectivity — the ecological, sociocultural, and economic interconnections that sustain the region.
Amazon Assessment Report 2021
The Science Panel for the Amazon released the Amazon Assessment Report 2021 at COP26, which has been called an “encyclopedia” of the Amazon region. This landmark report is unprecedented for its scientific and geographic scope, the inclusion of Indigenous scientists, and its transparency, having undergone peer review and public consultation.
AMAZON ASSESSMENT REPORT 2021
Part I: The Amazon as a Regional Entity of the Earth System
-
This chapter explores the evolution of geodiversity over three billion years of history. It shows that periods of continental rupture followed by mountain forming ultimately led to the fundamental physiographic subdivisions of the Amazon, and to a great wealth of landscapes, soils, mineral deposits, oil and gas reserves, and freshwater aquifers. Information on the geodiversity of the Amazon supports a central theme of environmental science, that the formation of most natural resources (such as rare minerals, hydrocarbons, freshwater aquifers, and fertile soils) requires that natural processes develop undisturbed over vast periods of geological time and over vast domains of space.
-
This chapter reviews the evolutionary history of the Amazon’s terrestrial and riverine ecosystems, involving geological and climatic events operating over millions of years and across the whole of continental South America. The chapter discusses the important roles of geographic barriers, habitat heterogeneity, climate change, and species interactions in generating and maintaining the most biodiverse ecosystems on Earth. This unique history produced heterogeneous environments and diverse habitats at multiple geographic scales, which altered the connections between populations and allowed for the accumulation of the most diverse biota on Earth.
-
This chapter provides an overview of biodiversity in the Amazon, discusses the reasons why this region is so rich in species and ecosystems, and outlines some outstanding ecological processes that make the Amazon an icon of the natural world. Featured terrestrial and aquatic taxonomic groups illustrate how much we know about diversity in the Amazon, and more importantly, how much we still do not know. A clear understanding of biodiversity levels and their spatial and temporal variations is crucial to understanding future stability under different climate change, land use change, forest fragmentation, and deforestation scenarios and informing conservation and restoration efforts.
-
This chapter describes the diversity of plants and ecosystems in the lowland Amazon and discusses how complex regional gradients in climate and soil conditions drive regional variability in species composition, vegetation dynamics, carbon stocks, and productivity. The Amazon river network and its role in connecting aquatic and terrestrial ecosystems through organisms and nutrient exchanges is also emphasized.
-
This chapter reviews the main features and large- to mesoscale mechanisms that contribute to the Amazon’s climate, its inter-annual and inter-decadal variability, and extreme drought and flood events. It examines the effects of extreme events on vegetation and the partitioning of precipitation into evapotranspiration (ET), runoff, flow seasonality, and floodplain dynamics; and describes the floodplain´s role in the biogeochemical cycle.
-
This chapter summarizes the cycles of three key biogeochemical elements, carbon, nitrogen and phosphorus, with a focus on carbon, spanning both terrestrial and aquatic ecosystems in Amazon. The chapter also examines the emissions of two key trace gases which make substantial contributions to radiative warming, methane and dinitrogen oxide, and summarizes trace gas and aerosol emissions from the Amazon and their impact on atmospheric pollution, cloud properties, and water cycling.
-
The main objective of this cross-chapter is to summarize the status of the Amazon as a source or sink of carbon (C). The processes and studies involved are detailed in other SPA chapters. The major challenge of determining the Amazon’s status as a net C source or sink at a continental scale is that many complex processes contribute to C fluxes.
-
This chapter assesses biogeophysical interactions between the Amazon rainforest and the climate. A historical perspective is presented, highlighting breakthroughs which improved our understanding of the mechanisms by which the rainforest interacts with the atmosphere.
-
Archaeology tells us how Indigenous peoples transformed nature in the Amazon over the millennia to the point that it is difficult to separate natural from cultural patrimony there today. It also shows that any kind of sustainable future for the region has to consider the rich Indigenous heritage manifested in archaeological sites and contemporary landscapes, and the contemporary knowledge of traditional societies.
-
This chapter covers the history of the Amazon between the 16th and 18th centuries, including myths that originated at that time and persist into the present, influencing political and social relations. It also highlights the main actors involved in this process and their narratives. Finally, it shows how the extraction of natural resources has been accompanied by the subjugation and exploitation of the workforce and the development of multiple forms of domination and extermination, especially of Indigenous peoples, since the era of European conquest.
-
This chapter explores the Amazon’s biocultural diversity, focusing on IPLCs’ worldviews, knowledge systems, livelihood strategies, and governance regimes. It synthesizes the main social and political processes that have led to the formal recognition of IPLCs’ lands and/or territories across the Amazon. The chapter highlights IPLCs’ critical role in using, shaping, conserving, and restoring Amazonian ecosystems and biodiversity, despite historic ongoing processes including violence, displacement, and conflicts between conservation and development agendas.
-
This chapter identifies the main economic processes that occurred in the Brazilian, Andean, and Guyanese Amazon from the 19th century until the 1970s. Specifically, the chapter describes the history of extractivism and the effects of geopolitical reconfiguration on the Amazon after the process of emancipation or decolonization. It analyzes the extraction of quina barks (species of the genus Chinchona, Rubiaceae) and rubber (Hevea brasiliensis, Euphorbiacae), as well as the resulting characteristics and practices developed by social actors related to the local and regional economy. It also describes the history and emergence of exploitation of oil and minerals (mainly gold), including the beginning of wildlife trafficking and the emergence of mechanized agriculture, intensive livestock, and mega-infrastructure.
-
This chapter covers the extraordinary Indigenous linguistic diversity of the Amazon region, including its different dimensions: the existence of a relatively large number of languages in the region; how these languages are related to each other, representing an impressive genealogical diversity; geographical distribution over different Amazonian subregions; the effects of language contact that have resulted in several linguistic areas; different levels of endangerment and the social circumstances that contribute to it; and, finally, what is lost when languages disappear.
-
This chapter provides evidence on the importance of African descendants in the construction of the Amazon and other tropical areas in the Americas, and highlights their importance for long-lasting sustainable development strategies in the region. It looks at both the cultural exchange and socio-historic perspectives, emphasizing land settlement patterns, natural resource use, and management practices. It focuses mostly on Brazil, Suriname, and Colombia, and emphasizes the importance of eliminating the invisibility of African descendant peoples in academic research and policy.
Part II: Social-Ecological Transformations: Changes in the Amazon
-
This chapter presents the major ideas, actors, and practices that have shaped the Amazon’s current development and deforestation dynamics. Outlining general periods of macro policy, it traces the evolution of today’s complex interactions among diverse livelihoods, conservation, and production systems, both legal and clandestine. It highlights how Amazonians have continuously adapted to changing circumstances while fighting to advance their own proposals for conservation and equity in development.
-
This chapter focuses on recent changes in the structure of systems of production in the Amazon, exploring their implications for the region’s environment and society. It also highlights local responses to these challenges, and opportunities for more sustainable production systems. An in-depth quantitative case study on the Brazilian Amazon is presented.
-
Two management classifications are the cornerstone of Amazonian conservation: protected areas and Indigenous territories. This chapter focuses on the historical processes, starting in the 1960s, that led to their creation, as well as the contemporary challenges they face and their importance for conservation.
-
From the 1970s on, the Amazon experienced its deepest transformation, becoming a commodity and energy provider for both domestic and international markets, through extraction of natural resources. Living conditions barely improved, and social conflict and violence became widespread, particularly affecting Indigenous peoples and local communities. Conservation efforts also became globalized and achieved significant results. Brazil’s 84% reduction in deforestation from 2005-2012, based on an integrated strategy with high political priority, provides an important case study that can support future policies across the basin. These gains were reversed in recent years, and unsustainable extractivist policies generally prevailed over conservation and the sustainable use of biodiversity in the whole Amazon basin (Chapter 18).
-
This chapter presents country-specific descriptions of human intervention in the Amazon, including the expansion of agricultural and extractive activities. The analysis contains two comprehensive national cases (Colombia and Ecuador) and three short studies focused on public policies (Peru, Bolivia and Venezuela). The Brazilian experience reducing deforestation is presented in Chapter 17.
-
This chapter discusses the main drivers of deforestation and forest degradation in the Amazon, particularly agricultural expansion, road construction, mining, oil and gas development, forest fires, edge effects, logging, and hunting. It also examines these activities’ impacts and synergies between them.
-
Amazonian aquatic ecosystems are being destroyed and threats to their integrity are projected to grow in number and intensity. Here we present some of the main impacts on aquatic ecosystems triggered by infrastructure projects and predatory and illegal practices.
-
Amazonian forests and aquatic ecosystems are the basis for several ecosystem services, all of which play a crucial role in people’s livelihoods, human well-being, and health. Some of the most relevant and challenging health problems in the Amazon are associated with deforestation and degradation of terrestrial and aquatic ecosystems, including the risk of contracting infectious diseases, respiratory problems caused by exposure to smoke from deforestation and forest fires, and mercury contamination caused by gold mining. Here we demonstrate that environmental degradation affects the health of millions of Amazonians.
-
This chapter describes the observed and projected changes in temperature, river discharge, and precipitation patterns and extremes in the Amazon region, as well as their impacts and possible thresholds. The emphasis is on the effect of climactic extremes on biodiversity and ecological processes.
-
This chapter presents observed and predicted impacts of climate change on Amazonian ecosystems, focusing on biodiversity, ecosystem services, carbon cycling, fisheries, and emissions from biomass burning. It also considers climate and land-use change feedback and highlights knowledge gaps to better understand these complex interactions.
-
This chapter reviews and discusses existing evidence of ongoing changes in the Amazon forest system that may lead to resilience loss and the potential to cross tipping points in which the ecosystem may shift either gradually or abruptly to a persistent, environmentally degraded configuration.
Part III: The Solution Space: Finding Sustainable Pathways for the Amazon
-
Developing a clear vision is the central starting point for any action plan. This chapter reviews the main visions regarding the Amazon and proposes a Living Amazon Vision based on a set of values, principles, and knowledge systems described throughout the chapter.
-
This chapter discusses the importance and limitations of the five SDG dimensions (People, Planet, Prosperity, Peace and Partnership) in the Amazonian context. It also discusses the performance and trends of Amazonian countries in achieving the SDGs.
-
Human activities destroy biodiversity and disrupt the functioning of aquatic and terrestrial ecosystems at different levels. This chapter provides sustainable approaches to address some of the biggest threats to the Amazon’s biodiversity and ecosystems, i.e., deforestation, damming of rivers, mining, hunting, illegal trade, drug, production and trafficking, illegal logging, overfishing, and infrastructure expansion. The role of restoration is addressed in chapters 28 and 29.
-
This chapter examines site-specific opportunities and approaches to restore terrestrial and aquatic systems, focusing on the local actions and benefits. Landscape and biome-wide considerations are addressed in Chapter 29.
-
Restoration can be applied in many different Amazonian contexts, but will be most effective at leveraging environmental and social benefits when it is prioritized across the Amazon basin, landscapes, and catchments. Here we outline the considerations that are most relevant for planning and scaling restoration across the Amazon.
-
The main objective of this cross-chapter is to summarize the status of the Amazon. This chapter highlights the paradox between the Amazon’s extraordinary socio-biodiversity and its distance from the scientific, technological, and market frontier of the contemporary bioeconomy. It discusses the current socioeconomic structures available in the region, as well as challenges and pathways for a transition to a socially-fair and sustainable bioeconomy.
-
Protected areas, Indigenous lands, and local communities’ territories play a critical role in holding back deforestation, maintaining regional and global climate stability, and – above all – protecting land rights. Nevertheless, these lands are currently threatened by political and economic interests that drive land speculation, agribusiness expansion, and illegal logging and mining, resulting in increasing deforestation rates. Governments are also reassessing and walking back territorial rights legislation.
-
Here, we provide three examples of Indigenous-led projects promoting sustainable development of Amazonian biocultural landscapes: the Amazon Sacred Headwaters initiative in Ecuador-Peru; the Ally Guayusa Cooperative in Ecuador; and the Amazon Hopes Collective in the Upper Xingu in Brazil.
-
This chapter aims to give visibility to participatory intercultural education experiences across the Amazon region. It starts with an examination of the issues with the general educational system, and then presents case studies which offer different paths forward. These case studies reflect not only the importance of participatory education for IPLCs, but also how knowledge is itself a form of communication and political influence that helps IPLCs guarantee their rights.
-
This chapter highlights the under-recognized importance of ILK to conservation and sustainable development efforts across the Amazon, utilizing the conceptual framework of public participation in scientific research. It reviews a range of illustrative examples which articulate ILK and mainstream scientific and technical knowledges in conservation and development initiatives. We also consider recent policy recommendations and guidelines by professional associations and civil society organizations.
-
By providing a brief and non-authoritative analysis of the physical and cultural relations between rural (forest) and urban areas in the Amazon, we identify several points for improvement, such as economic incentives to encourage healthcare professionals to serve the countryside, implementing peri-urban agricultural belts to improve urban food security, increasing access to urban green spaces, and investing in innovation around the “smart cities, smart forests” concept. Perhaps most importantly, this would include mobilizing human, financial, and institutional resources to restore cultural, spiritual, and affective bonds between urban and forest inhabitants.
