Here's The Path To Conserving Protected Areas In The Amazon
Despite serving as crucial guardians of biodiversity, traditional communities continue to be systematically excluded 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 Journal for Nature Conservation, mapped how scientific literature has examined these conflicts over time.
Researchers from the Federal University of Western Pará (UFOPA), the Federal University of Pará (UFPA), the University of International Integration of Afro-Brazilian Lusophony (UNILAB), and the Vale Institute of Technology (ITV) collaborated on the study as part of the National Institute of Science and Technology in Synthesis of Amazonian Biodiversity (INCT-SynBiAm) and the Eastern Amazon Biodiversity Research Program (PPBio-AmOr).
The team reviewed 263 scientific articles published worldwide between 1990 and August 2024, sourced from Scopus and Web of Science. 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:
1. 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 Nech Sar National Park, new conservation policies have curtailed local residents' access to natu re, sparking community tension and resistance.
2. 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 study in Chile involving Aymaras, Atacameñas, and Mapuche-Huilliches communities found that while participatory practices and technical support from the CONAF 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.
3. 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 rising human-wildlife conflict in Chebera Churchura National Park: crop invasion, livestock predation and disease, and increased risks to human life were all reported.
4. 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 recent study 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.
5. 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, studies have noted 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.
6. 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 Monti Sibillini National Park in the Central Apennines offers an instructive case: rural depopulation has coincided with rising friction between environmental managers and locals. 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. Research 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, embedding traditional knowledge 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 excluding local scientists and communities 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 empowering Amazonian scientific institutions and researchers, 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 deep, context-sensitive knowledge of the territory, 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 enables more authentic community participation in research. 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.

The enigmatic wild ancestors of domestic tabbies
The Afro-Asiatic wildcat (Felis lybica) is the world's most widely distributed wildcat, but experts and information on the species are scarce. The species' range is immense, stretching across most of Africa, Southwest and Central Asia, India, China and Mongolia. But Arash Ghoddousi, lead author for F lybica 's 2022 IUCN species conservation assessment, says the study team found 'few people [who] knew anything about the cats'. That seeming lack of human curiosity is surprising, considering the domestic tabbies we keep as pets and lavish billions of dollars on annually are descended, and still closely related to, the Afro-Asiatic wildcat. One researcher who has shown intense interest is Marna Herbst, now a regional ecologist for South African National Parks. Previous research on F lybica had been based on opportunistic sightings and scat and stomach analysis. Herbst changed that, spending roughly four years and 10-12 hours nightly observing the cats in the harsh unforgiving landscape of the southern Kalahari Desert for her PhD research, published in 2009. She was the first (and remains the only) scientist to conduct such a long-term study on the species documenting its behaviors and population genetics. Searching for the wildcat Herbst carried out her study in the Kgalagadi Transfrontier Park, a known African wildcat habitat straddling the borders of South Africa and Botswana. The small wildcats there were assumed to be far enough from urban areas to still be genetically pure, not having interbred with domestic cats (deemed one of the wild species' greatest risks). Sighting the little wildcats relatively often, Herbst hoped they would also be relatively easy to catch, collar and track. They weren't. Twenty years later, she recalls the challenges. The small cats are shy and elusive, taking cover in fox or aardvark holes and under tree roots; on farms, they hide amid tall, dense corn stalks. Adding to her difficulties, the cat is nocturnal and practically impossible to study in its habitat without aid of radio telemetry. To accomplish that, they must first be caught. Herbst recalls that in trying, she captured lots of other stuff. Jackals in particular were attracted to the chicken-baited cage traps. But over time, she succeeded in catching and collaring numbers of the elusive cats. Another hazard of low-budget research on a noncharismatic species: Herbst's hand-me-down 4×4 vehicle, in which she spent countless hours alone rumbling in the dark over roadless terrain, took a terrible beating. But those nights rewarded her with sights few ever see, encountering the park's big cats, including the famed black-maned lion (Panthera leo leo), cheetah (Acinonyx jubatus) and leopard (P pardus). Once in the dark, while sipping coffee inside her 4×4, she was startled by a full-grown hyena that nonchalantly sniffed the side-view mirror. They're 'much bigger than you think', she says. Over time, Herbst came to know the Afro-Asiatic wildcat as 'a really special little species that plays a vital role in ecosystems'. Small cat, big adaptability You could be forgiven for mistaking an Afro-Asiatic wildcat for a family pet. They're the size of a large domestic cat (F catus), but with longer legs. Their coloration varies by region from reddish, sandy and tawny brown, to greyish. They sport faint tabby stripes or spots, more pronounced in humid areas, and paler and darker in drier climes. Their tails are slim and tapered with a dark tip. A distinguishing feature, Herbst says, is the pinkish-orange tint of their ears. Afro-Asiatic wildcats are highly adaptable to landscape (especially bush and steppe), season and prey availability. They prefer hunting small rodents but dabble in reptiles and invertebrates. Herbst recalls male cats taking down spring hares roughly the same size as they were. Cats with waterholes in their territories became bird-hunting specialists. One female was great at hunting sandgrouse as they came to drink. The stomach of an Afro-Asiatic wildcat from Oman contained beetles, grasshoppers, lizards, mammal fur and a date pit. The species is mostly solitary and roams widely. In the United Arab Emirates, a collared cat had a larger home range (52.7 square kilometers or 20.3 square miles), far larger than that reported in the more optimal habitat (around 3.5 km² or 1.4 mi²) of the Kalahari, where food and water are relatively easy at hand. Ghoddousi says the wildcat's remarkable adaptability to various habitats, tolerance of different elevations and climates, plus its capacity to coexist with larger predators make it very special – allowing it to spread over two continents. Because they're so widely distributed, with incidental sightings reported from many locations, the species is considered relatively stable and 'of least concern'. But Ghoddousi warns this might not reflect the species' true state in the wild. Due to lack of research, and therefore lack of data, the real-world trend for far-flung Afro-Asiatic wildcat populations remains unknown. Ghoddousi says the big risk is that, as global change escalates, the species could slip away before science notices and conservationists can take action. Ranging over such a wide area, the Afro-Asiatic wildcat goes by many regional names. It's the African wildcat to some, the Asiatic wildcat to others, and the Indian desert cat to still others. Scientifically, the Afro-Asiatic wildcat is divided into three evolutionarily similar subspecies. The first, F lybica lybica, occurs in Eastern, Western and Northern Africa and the Arabian Peninsula. The second, F lybica cafra (the topic of Herbst's PhD), occurs in Southern Africa. The third, F lybica ornata, is found in Southwestern and Central Asia, Pakistan, India, Mongolia and China. The precise boundaries of subspecies' ranges are unclear. Until 2017, these three subspecies were lumped together with the European wildcat and considered subspecies of F silvestris. But further investigation demanded a split: Now, populations that roam from the steppes and bush of Africa and Asia are classified as F lybica, while the European wildcat is classified as a separate species (with its bushy tail and more distinctive coat markings, F silvestris occurs in fragmented populations across Europe, Turkey and the Caucasus. These geographically separated cat populations mixed things up genetically at various points in time, due to natural changes or, sometimes, thanks to people. Thousands of years ago, this long-term and complex intermingling process birthed the first domestic cat. Domestication Paleogeneticist Claudio Ottoni wouldn't describe himself as a cat person, and his work takes place far from the wild. But under his microscope, the ancient lives and movements of the Afro-Asiatic wildcat come to life, revealing hints to the tantalising mystery as to how it long ago threw in its lot with humanity to evolve into today's domestic cat species. Paleogeneticists, it turns out, find the small wildcat just as elusive as field biologists. Compared with other domesticated animals, hypotheses about early cat domestication remain grounded in scant evidence and open questions. Ancient cat bones are scarce, and distinguishing differences between wild and domestic skeletal features is challenging. But Ottoni has been a dogged researcher, puzzling for years over perplexing data, embracing and developing a hypothesis, then revising the shape of that hypothesis as new technology and data become available to move toward a more robust theory. An early theory, published in 2017, was that farmers in southwest Africa had domesticated cats and brought them to Cyprus in the early Neolithic period (at least 7,000 years ago) to control rats and mice that damaged stored grain. This origin story was based on clues found in the DNA of 352 long-dead felids. Researchers analysed maternally inherited mitochondrial DNA in bits of cat bone and teeth, as well as skin and hair samples found at archaeological sites. The oldest samples included a complete cat skeleton, dated to roughly 7500 BCE, found buried with a man on Cyprus, suggesting the hypothesis that domestication started here. Other samples included six skeletons, dating to around 3700 BCE, found in an elite Predynastic Egyptian cemetery. Still other examples were found in archaeological digs at the Roman-Egyptian port of Berenike on the Red Sea. Ottoni also compared the ancient cat DNA samples with modern wildcat samples from Bulgaria and Eastern Africa. Together, the DNA seemed to indicate that the domestic cat's worldwide conquest began in the Fertile Crescent (perhaps on Cyprus some 7,000 years ago), then gained momentum during Classical Antiquity about 2,500 years ago, when the Egyptian cat successfully spread throughout the Old World along land and sea trade routes. This analysis seemed to confirm that while the Afro-Asiatic wildcat was the ultimate source of the domesticated cat, its evolution and spread wasn't simple: Though the North African/Southwest Asian F lybica was a source, both the Near Eastern and Egyptian F lybica populations also contributed to the domestic cat's gene pool at several points in history. New tech, better theory Since 2017, new technology and more data have modified, added detail and complicated this storyline. While earlier work relied on mitochondrial DNA analysis, researchers were able to analyse nuclear DNA for an updated theory in 2025. This higher-resolution analysis reveals the full genetic code of individual cat specimens, including not only the maternal, but also the paternal inherited DNA. It provides 'the actual ancestry,' Ottoni says. And this new data punched an unexpected hole in the previous theory of cat domestication. For one, domestication happened thousands of years later than thought, and then was probably not due to African farmers who traveled to Cyprus. 'Evolutionarily speaking, it's a very peculiar case,' Ottoni says of the discordance between the 2017 and 2025 DNA findings. The new data showed what scientists call 'mitonuclear discordance,' where analyses using mitochondrial DNA markers yield different conclusions than those using nuclear DNA markers. Surprisingly, samples that the researchers thought were F. lybica turned out to be those of the European wildcat. So, while wildcats were indeed taken to Cyprus, Ottoni explains, this might have been an isolated attempt of Neoolithic people to domesticate European wildcats, rather than wildcats brought from Africa. The evidence now suggests that European wildcat and African wildcat distribution probably overlapped in the past, perhaps due to climatic shifts or other natural causes. Because both species are interfertile, they sporadically bred, leading to a mixed population living in Turkey. According to the updated theory, domestic cats with a lybica genome only appeared in Europe about 2000 years ago, during Classical Antiquity, Ottoni says, but then adds, 'We can't say precisely when the domestication process that led to the cat dispersal started.' Perhaps, and more likely, domesticated cats did come first from Egypt, where cats were buried in the Hierakonpolis (the ancient Egyptian royal residence). But whatever the exact origin story, we do know that 'in evolutionary terms, [the domestic cat is] one of the most successful mammal species in the world,' Ottoni says. Domestic cats today are found on every continent except Antarctica. (They were introduced to sub-Antarctic Marion Island in 1949 to control mice, but were later eradicated due to negative impacts on native birds.) Researchers have also learned that the close genetic kinship shared by domesticated and wild felids species really matters: The widespread prevalence of F catus, and its capacity to interbreed with F lybica, is among the most serious threats to the Afro-Asiatic wildcat's survival. Big challenges Hybridisation with domestic cats is widespread across the Afro-Asiatic wildcat's range, though some studies, including Herbst's work, have shown that wildcat populations in South Africa at least, especially in protected areas, appear to remain genetically pure. However, according to the 2022 IUCN species assessment, there's insufficient information on the level of hybridisation with domestic cats in other parts of the range, and therefore, this threat should not be underestimated or ignored. As such, Herbst points to responsible pet ownership as key to Afro-Asiatic wildcat survival. That includes spaying by pet owners of their domestic cats that aren't being bred, and also community spaying of feral cats (especially in urban areas bordering protected areas where wildcats live). Education is important, too, she notes. Though spaying is an important conservation measure, spayed domestic cats can still seriously impact wildcat food sources. The IUCN assessment points out that feral domestic cats compete with wildcats for prey and space, and there is also a high potential for disease transmission between them. Other threats include the risk of roadkill and poisoning and conflicts with farmers and local people due to attacks on poultry by wildcats leading to retaliatory killings. Another serious threat, Ghoddousi says, is lack of information, causing scientists to underestimate the risk a species faces. Unfortunately, that is always the case when you don't have enough data, he says. You can't make a meaningful judgment about a species status if you simply do not know.

9 most deadliest spiders in the world that could endanger you by their venom
Spiders are fascinating creatures that play an important role in the ecosystem but some species carry venom which are potent enough to pose serious risks to humans. Across the globe, a handful of spiders stand out for their dangerous bites which can cause severe pain, illness or even death if untreated. While most spiders avoid people, encounters with these venomous species can happen in homes, forests and even urban areas. In this list, we explore nine of the most dangerous spiders worldwide by revealing their unique traits, habitats and the real dangers their venom presents. World's deadliest spiders including wolf spider , red widow spiders, and more Brown recluse spider The Brown Recluse Spider is also known as Loxosceles reclusa and is one of the most dangerous spiders in North America due to its venomous bite. They are easily recognizable by their violin-shaped marking on the back. This spider is shy and usually hides in dark and undisturbed places like closets or woodpiles. Its bite can cause serious skin necrosis which can lead to painful ulcers and tissue damage that may require medical treatment. Though rarely fatal, the venom can cause systemic symptoms in some cases. Because bites are often painless initially, many victims don't realize they've been bitten until symptoms develop that makes it a stealthy threat. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Why Didn't Anyone Tell You About This Power Saver? elecTrick - Save upto 80% on Power Bill Pre-Order Undo Source: Wikipedia Brazilian wandering spiders The Brazilian Wandering Spiders including Phoneutria fera and P. nigriventer are among the most venomous and aggressive spiders in the world. They are found in tropical South American forests and these spiders are named for their roaming hunting style rather than building webs. Their venom contains potent neurotoxins that can cause severe pain, muscle paralysis and in rare cases, death if untreated. They are known for their quick movements and defensive behavior and they often hide in banana plantations and other places frequented by humans, earning the nickname "banana spiders. " Immediate medical attention is crucial after a bite to prevent serious complications. Source: Wikipedia Yellow sac spider The Yellow Sac Spider, also known as Cheiracanthium inclusum, is a venomous spider that is commonly found in North and Central America. They are easily recognizable by its pale yellow or light green color and often prefer to live indoors, hiding in corners, curtains and ceilings. Its bite can cause mild to moderate pain, redness and swelling that can sometimes lead to skin irritation or small ulcers. Though they are not usually dangerous to humans, their venom contains enzymes that can cause tissue breakdown, making bites uncomfortable and slow to heal. While generally not aggressive, the Yellow Sac Spider will bite if provoked, making it a spider to watch out for in homes. Source: Wikipedia Wolf spider Wolf Spiders belong to the family of Lycosidae and are known for their speed and hunting skills rather than webs. They are found worldwide and are typically large, hair, and agile hunters that roam the ground at night. While their venom is not deadly to humans, wolf spider bites can cause pain, swelling and itching. They usually bite only when threatened or handled and their bites can sometimes lead to mild allergic reactions. Despite their fearsome appearance, wolf spiders play a beneficial role by controlling insect populations in gardens and natural habitats. Source: Wikipedia Black Widow Spider The Black Widow Spider also known as Latrodectus mactans is infamous for its potent venom and distinctive appearance with a shiny black body and a red hourglass marking on its abdomen. Found throughout North America, it prefers dark, secluded areas such as woodpiles, sheds and garages.
