The path to conserving protected areas in the Amazon lies in uniting public policy with traditional local knowledge

Despite serving as crucial guardians of biodiversity, from developing and managing protected areas. This often subtle, silent exclusion has fueled persistent, complex socio-environmental conflicts, harming both conservation and the welfare of Indigenous peoples, riverside populations, Afro-Brazilian quilombola communities, and smallholder farmers.

A recent study, "Socio-environmental Conflicts and Traditional Communities in Protected Areas: A Scientometric Analysis," published in the , mapped how scientific literature has examined these conflicts over time.

Researchers from the Federal University of Western Pará (), the Federal University of Pará (), the University of International Integration of Afro-Brazilian Lusophony (), and the Vale Institute of Technology () collaborated on the study as part of the National Institute of Science and Technology in Synthesis of Amazonian Biodiversity () and the Eastern Amazon Biodiversity Research Program ().

The team reviewed 263 scientific articles published worldwide between 1990 and August 2024, sourced from and . Their analysis revealed significant gaps in research on this topic and offered recommendations for more just, inclusive, and effective management of protected territories.

What does science reveal about these conflicts?

The research shows not only a rise in conflicts involving traditional communities and protected zones, but also their diversity. The main sources of tension are:

• Access to subsistence resources: Local prohibitions—often unilaterally enacted—restrict fishing, hunting, gathering, and subsistence agriculture, all vital for food and income. These constraints sever longstanding traditions of sustainable resource use, leading to food insecurity and marginalization.
  
  • For example, in Ethiopia's , new conservation policies have , sparking community tension and resistance.

• Exclusionary management of protected areas: Community voices are rarely included in decisions about protected area creation or management. The absence of prior consultation and disregard for traditional knowledge often yield policies disconnected from local realities. Such centralized management breeds resentment and undermines conservation; participatory governance is essential to socio-environmental justice.
  
  • A involving Aymaras, Atacameñas, and Mapuche-Huilliches communities found that while participatory practices and technical support from the forest agency improved perceptions, dissatisfaction persists due to initial exclusion. Many continue to assert ancestral land rights and demand meaningful input, highlighting the urgent need to build trust and align conservation with social justice.

• Conflicts involving wildlife: Local communities contend with damaged crops, attacks on domestic animals, and even threats to personal safety. Large mammals such as elephants, lions, jaguars, and buffalo are the main culprits. Habitat loss and depleted food sources exacerbate these incidents. Peaceful coexistence requires inclusive, context-specific solutions.
  
  • A study from Ethiopia highlighted : crop invasion, livestock predation and disease, and increased risks to human life were all reported.

• Territorial disputes and land rights: Many protected areas overlap with territories long used by traditional peoples. Disavowed land rights provoke legal battles, forced displacement, and greater insecurity, compounding social challenges. Formal recognition of collective land title is key to reducing conflict and ensuring autonomy; these disputes exemplify the global fight for territorial justice.
  
  • In Mexico, a documents the impact of land privatization, livestock expansion, plantations, and urbanization in the protected areas of Veracruz, Chiapas, and Morelos. It generated a land market that is disrupting Indigenous and peasant communities and threatening both their territories and forest conservation.

• Cultural and socioeconomic disruption: Establishing protected areas can upend ways of life rooted in symbolic, generational relationships with nature. Prohibiting customary practices disrupts rituals, beliefs, and the intergenerational transmission of knowledge, silently eroding local cultures.
  
  • In the United States, Australia, and New Zealand, frequent friction between Indigenous groups, recreational visitors, and managing agencies. Issues include access to sacred sites and resources on traditional lands, visitor infrastructure, permitted activities, and even place names.

• Lack of recognition and real participation: When communities are denied a voice in decisions, historical inequities deepen, fueling conflict. Despite legal progress, many traditional groups remain excluded from governance. Without meaningful participation, environmental policy fails to address local needs—highlighting the urgent need for community leadership and real power-sharing in conservation.
  
  • Italy's in the Central Apennines offers an instructive case: rural depopulation has coincided with . Imposed bureaucratic guidelines, unresponsiveness to community aspirations, and challenging collaboration between the park and municipalities have generated mutual frustration and hostility. This underscores the need for "knowledge democracy" and truly participatory stewardship that respects diverse ways of living on the land.

Within Brazil, the same types of socio-environmental strife observed worldwide are especially acute in national protected areas. shows that even in sustainably managed zones like Extractive Reserves, communities regularly face resource restrictions and limited decision-making power—a recipe for lingering resentment and compromised conservation. Centralized authority and denial of customary land rights often lead to drawn-out disputes, mirroring patterns across the Global South.

These findings highlight Brazil's urgent need for strong co-management models—mechanisms that value local knowledge and foster territorial justice.

Such tensions cluster in nature reserves and national parks, where regulatory regimes often disregard local lifeways and worldviews. Although the law guarantees consultation and participation mechanisms like free, prior, and informed consultation, they are often ignored or implemented ineffectively.

Another key finding: 66.54% of studies focused on non-Indigenous populations, while only 16.73% examined Indigenous peoples exclusively. This imbalance exposes the under-representation of research attentive to the full range of traditional communities.

Such gaps hinder efforts to understand these peoples' rich cultural and ecological realities—and in turn, weakens recognition of their expertise and the value of their knowledge for global biodiversity conservation. Scientific consensus now affirms the vital role these communities play in preservation, yet too often they are treated as problems to be managed, not as collaborative partners.

Why does conservation demand inclusion?

Ensuring traditional communities participate in planning and stewarding protected lands is not only a matter of justice, but fundamental to effective conservation. Sustainable outcomes depend on their involvement. This study underscores the urgent need for public policies that are both inclusive and tailored to local conditions, as an indispensable part of conservation solutions, not as an obstacle.

Worldwide, co-management experiments show that community involvement fosters compliance with conservation rules, improves governance, and delivers stronger socio-environmental benefits.

Shifting the focus to Amazonian science

While most studies reviewed focus on countries in the Global South—like Brazil and India—research production is dominated by institutions in the Global North. This reflects persistent "parachute science": fieldwork by foreign scientists in rich biodiversity zones, often from the research process. Such projects often leave little local benefit, treating Amazonian residents as data collectors or study subjects.

To address this, efforts must shift toward , strengthening their role in shaping conservation and research agendas, and realizing epistemic justice. Investments are especially needed in institutions serving remote, often overlooked regions of the Amazon.

With robust support, these institutions can fill crucial gaps—producing research attuned to local realities, expanding our understanding of Amazonian ecosystems, and inspiring new generations of scientists.

Researchers living and working in the Amazon possess , enabling them to pose more relevant questions and craft solutions suited to regional challenges and opportunities. Their scholarship, in ongoing dialogue with both environment and community, enriches global science and yields practical advances that matter for daily life in the forest.

Proximity to Indigenous, riverside, and urban populations also . When research projects originate from local priorities and perspectives, they strengthen communities, help protect biodiversity, and affirm the possibility of uniting science, social justice, and climate action.
