Uncontacted Indigenous groups could vanish within a decade without stronger protections, experts say.
A railway line now planned in Brazil could potentially affect three uncontacted peoples, she said, but the rise of organized crime poses an even greater risk.
Across Peru, Brazil, Colombia, Venezuela and Ecuador, drug traffickers and illegal gold miners have moved deep into Indigenous territories. “Any chance encounter runs the risk of transmitting the flu, which can easily wipe out an uncontacted people within a year of contact,” she said. “And bows and arrows are no match for guns.”
Evangelical missionary incursions have also caused outbreaks. Watson recalled how, under former Brazilian President Jair Bolsonaro, an evangelical pastor was placed in charge of the government’s unit for uncontacted peoples and gained access to their coordinates. “Their mission was to force contact — to ‘save souls,’” she said. “That is incredibly dangerous.”
Ways to protect uncontacted peoples
Protecting uncontacted peoples, experts say, will require both stronger laws and a shift in how the world views them — not as relics of the past, but as citizens of the planet whose survival affects everyone’s future.
Advocates have several recommendations.
First, governments must formally recognize and enforce Indigenous territories, making them off-limits to extractive industries.
Mapping is crucial, Bhattacharjee said, because identifying the approximate territories of uncontacted peoples allows governments to protect those areas from loggers or miners. But, she added, it must be done with extreme caution and from a distance to avoid contact that could endanger the groups’ health or autonomy.
Second, corporations and consumers must help stop the flow of money driving destruction. Survival’s report calls for companies to trace their supply chains to ensure that commodities such as gold, timber and soy are not sourced from Indigenous lands.
“Public opinion and pressure are essential,” Watson said. “It’s largely through citizens and the media that so much has already been achieved to recognize uncontacted peoples and their rights.”
Finally, advocates say the world must recognize why their protection matters. Beyond human rights, these communities play an outsized role in stabilizing the global climate.
“With the world under pressure from climate change, we will sink or swim together,” Bhattacharjee said.
Governments’ uneven response
International treaties such as the International Labor Organization’s Convention 169 and the UN Declaration on the Rights of Indigenous Peoples affirm the right to self-determination and to remain uncontacted if they choose. But enforcement varies widely.
In Peru, Congress recently rejected a proposal to create the Yavari-Mirim Indigenous Reserve, a move Indigenous federations said leaves isolated groups exposed to loggers and traffickers.
In Brazil, President Luiz Inácio Lula da Silva has sought to rebuild protections weakened under Bolsonaro, boosting budgets and patrols.
And in Ecuador, the Inter-American Court of Human Rights ruled this year that the government failed to protect the Tagaeri and Taromenane peoples who live in voluntary isolation in Yasuni National Park.
Watson warned that political forces tied to agribusiness and evangelical blocs are now working to roll back earlier gains.
“Achievements of the last 20 or 30 years are in danger of being dismantled,” she said.
What the new report calls for
Survival International’s report urges a global no-contact policy: legal recognition of uncontacted territories, suspension of mining, oil and agribusiness projects in or near those lands and prosecution of crimes against Indigenous groups.
Watson said logging remains the biggest single threat, but mining is close behind. She pointed to the uncontacted Hongana Manyawa on Indonesia’s Halmahera Island, where nickel for electric-vehicle batteries is being mined.
“People think electric cars are a green alternative,” she said, “but mining companies are operating on the land of uncontacted peoples and posing enormous threats.”
In South America, illegal gold miners in the Yanomami territory of Brazil and Venezuela continue to use mercury to extract gold — contamination that has poisoned rivers and fish.
“The impact is devastating — socially and physically,” Watson said.
