Content warning: this article contains references to suicide, which readers may find distressing.
Suicide is a major global public health issue, leading to approximately 700,000 deaths each year. While the global suicide rate decreased by 36% from 2000 to 2019, Brazil saw a dramatic 43% rise in suicide cases during the same period.
A study conducted by the Oswaldo Cruz Foundation (Fiocruz), in collaboration with Harvard University, found that Brazil recorded 147,698 suicides between 2011 and 2022. In 2022, the Indigenous population had the highest rates of self-harm notifications (103.72 per 100,000) and suicides (16.58 deaths per 100,000), compared to the overall population, which reported rates of 70.06 and 7.27 per 100,000, respectively.
Territorial conflicts, the expansion of agribusiness, oil and gas exploration, infrastructure projects, both legal and illegal mining and logging activities, along with discrimination, inequality, climate change, violation of Indigenous rights, inadequate state protection, and lack of permanent policies, are significant contributors to the increasing suicide rates among Indigenous People in Brazil.
High suicide rates for Indigenous People in Brazil
Daiane Borges Machado, one of the authors of the Fiocruz study, mentioned:
Increasing suicide rates among Indigenous communities are deeply rooted in a complex web of systemic challenges. These populations have long been dramatically exposed to violence, territorial disputes, and the expansion of industries like agribusiness, mining, and logging, all of which severely impact Indigenous lands and ways of life. These activities not only threaten physical spaces but also disrupt the social and cultural connections that are vital for well-being.
Additionally, longstanding issues such as inequality, discrimination, and inadequate state protection highlight the failure to implement effective, permanent policies that safeguard Indigenous rights and health. Addressing these interconnected issues requires a holistic approach, focusing on cultural preservation, sustainable development, and equitable policy implementation.
Brazil’s Indigenous population exceeds 1.7 million, with more than half living in the Legal Amazon, based on the 2022 Census by the Brazilian Institute of Geography and Statistics (IBGE).
A report from Brazil’s Indigenous Missionary Council (Cimi) revealed that suicides among Indigenous people in Brazil rose by 56% in 2023, totalling 180 cases compared to 115 the previous year. This data may be underestimated due to flaws in Brazil’s death verification and registration system.
Young Indigenous People taking their lives
From 2019 to 2022, Brazil recorded a total of 535 suicides among Indigenous People. The highest number of cases occurred in Amazonas (208), followed by Mato Grosso do Sul (131) and Roraima (57). In 2023, Amazonas again had the highest number of suicides (66), followed by Mato Grosso do Sul (37) and Roraima (19). More than a third of all cases, totalling 59, involved individuals aged 19 and younger.
Jacyra Azevedo Paiva de Araujo, one of the authors of the Fiocruz study, stated:
It is essential to ensure that government agencies are actively engaged, adequately funded, and properly equipped to maintain a strong presence and function effectively in the region. This would help reduce violence, protect Indigenous lands, and lower the risk of suicide. Since suicide risk is closely linked to mental health disorders, providing access to mental health care must be a priority. While Brazil’s public health system offers mental health treatment to the entire population, these services need to be tailored specifically to the needs of Indigenous communities in these areas.
Jesem Orellana, an epidemiologist at Fiocruz, highlighted that suicide rates among Indigenous populations are associated not only with depression but also with socioeconomic factors such as inequality, economic crises, discrimination, and the decline of Indigenous traditions and practices, including hunting, fishing, and agriculture. Orellana explained that:
Suicide is known to be a complex and multicausal phenomenon. However, in indigenous contexts, sociocultural factors associated with the symbolic and cosmological universe or even with the clash between ancestral traditions and antagonistic worldviews, such as Western ones, tend to play an important role in the tragic statistics of indigenous suicide, especially among younger people.
Territorial conflicts and violence
The invasion of Indigenous lands and territorial disputes continue to be major issues that contribute to the ongoing pressures these communities face. Numerous cases of intimidation, threats, sexual assaults, and violent attacks against Indigenous communities have been reported in Brazil.
The states of Roraima, Mato Grosso do Sul and Amazonas have recorded the highest rates of assassinations.
The Cimi report indicates that invasions of Indigenous lands rose by 252% from 2019 to 2022, compared to earlier years. This period also saw an increase in cases of homicide, sexual violence, and death threats against Indigenous People.
The key factors behind the violence against Indigenous communities include the expansion of agribusiness, cattle farming, oil and gas extraction, both legal and illegal mining, fishing, hunting, and logging, as well as infrastructure projects such as road, railway, and dam construction, along with the private appropriation of their territories.
Indigenous People frequently feel pressured to leave their land due to concerns for their safety.
Of the 1,381 Indigenous lands and territorial claims in Brazil, 62% are still facing administrative obstacles to their regularisation, with 850 pending resolutions, and 563 having received no action from the state regarding demarcation.
Capitalist threats to Indigenous communities
The Brazilian government’s support for expanding oil and gas projects in the Amazon, along with agribusiness, cattle farming, mining, and infrastructure projects like the Ferrogrão railway – linking the port of Miritituba in Pará to Sinop in Mato Grosso – and the recently approved BR-319 highway, is expected to have devastating impacts on the environment and Indigenous communities.
The reconstruction of Amazon’s BR-319 highway, which connects Manaus, the capital of Amazonas, to Porto Velho, will affect 64 Indigenous territories. This project is key for the expansion of agribusiness, oil and gas exploration, illegal mining, logging, and organised crime, all of which will directly threaten Indigenous communities in the region.
In Brazil, Indigenous communities are confronted with a multitude of challenges, frequently left to face life-threatening conditions without sufficient state protection. This lack of support undermines their ability to defend their rights and has driven some to such desperation that they resort to extreme actions, including tragically taking their own lives.
Mining and mercury contamination causing displacement
Climate change and global warming leads to environmental degradation, posing yet another threat to Indigenous communities. Their livelihoods, dependant on agriculture, fishing, and hunting, have been affected by rising temperatures, droughts, and extreme weather events.
The rise in fires and droughts is pushing Indigenous People to leave their lands and seek work in urban centres. However, they often struggle to find employment, leading to economic difficulties and, at times, an inability to sustain themselves.
The lack of job opportunities and a sense of purpose can lead to substance abuse, with drugs and alcohol becoming an escape, often resulting in severe depression and, tragically, sometimes suicide.
Illegal mining is a critical issue affecting Indigenous communities in Brazil. A Fiocruz study discovered alarming mercury concentrations in hair samples and oral swabs from 293 Yanomami individuals in nine villages located in the upper Mucajaí River area of Roraima.
The mercury levels were three times higher than the recommended safety limits, primarily due to fish contamination, which is a staple in the Yanomami diet. Additionally, cognitive impairments were found in 55.2% of the children across these villages.
Mercury is a neurotoxin, and high levels of exposure can lead to damage to the nervous system, gastrointestinal tract, and kidneys. Symptoms of high exposure include cognitive disturbances, memory impairment, mood swings, muscle weakness, and skin conditions such as rashes and dermatitis.
A study published in the journal Environmental Health Perspectives found that maternal consumption of mercury-contaminated fish during pregnancy over three generations contributed to children’s poor mental health, with emotional and behavioural issues linked directly to an increased risk of attempted suicide.
Mass exodus
The degradation and contamination of Indigenous lands and water sources drive the Indigenous communities to move to the cities in search of work, exposing them to a range of challenges that can have devastating outcomes.
Preserving Indigenous knowledge and practices is vital for safeguarding the physical and mental well-being of Brazil’s Indigenous populations. The contamination of their land and water forces these communities to relocate to urban areas in search of survival, disrupting their traditional lifestyles.
As they adapt, many turn to ultra-processed foods, alcohol, and drugs – substances foreign to their bodies – which can severely affect their health. This shift often results in increased rates of depression, self-harm, and suicide, highlighting the urgent need to protect their heritage and support their communities.
