Genocide of indigenous peoples in Brazil
The genocide of indigenous peoples in Brazil began with the Portuguese colonization of the Americas, when Pedro Álvares Cabral made landfall in what is now the country of Brazil in 1500. This started the process that led to the depopulation of the indigenous peoples in Brazil, because of disease and violent treatment by European settlers, and their gradual replacement with colonists from Europe and Africa. This process has been described as a genocide, and continues into the modern era with the ongoing destruction of indigenous peoples of the Amazonian region. Over eighty indigenous tribes  were destroyed between 1900 and 1957, and the overall indigenous population declined by over eighty percent, from over one million to around two hundred thousand. The 1988 Brazilian Constitution recognises indigenous peoples' right to pursue their traditional ways of life and to the permanent and exclusive possession of their "traditional lands", which are demarcated as Indigenous Territories. In practice, however, Brazil's indigenous people still face a number of external threats and challenges to their continued existence and cultural heritage. The process of demarcation is slow—often involving protracted legal battles—and FUNAI do not have sufficient resources to enforce  the legal protection on indigenous land. Since the 1980s there has been a boom in the exploitation of the Amazon Rainforest for mining, logging and cattle ranching, posing a severe threat to the region's indigenous population. Settlers illegally encroaching on indigenous land continue to destroy the environment necessary for indigenous peoples' traditional ways of life, provoke violent confrontations and spread disease. Peoples such as the Akuntsu and Kanoê have been brought to the brink of extinction within the last three decades. On 13 November 2012, the Articulation of Indigenous Peoples of Brazil (APIB) submitted to the United Nations a  human rights document with complaints about new proposed laws in Brazil that would further undermine their rights if approved. Several non-governmental organizations (NGOs) have been formed due to the ongoing persecution of the indigenous peoples in Brazil, and international pressure has been brought to bear on the state after the release of the Figueiredo Report which documented massive human rights violations. The abuses have been described as genocide, ethnocide and cultural genocide. Affected tribes. In the 1940s the state and the Indian Protection Service (Serviço de Proteção aos Índios, SPI) forcibly relocated the Aikanã, Kanôc, Kwazá and Salamái tribes  to work on rubber plantations. During the journey many of the indigenous peoples starved to death; those who survived the journey were placed in an IPS settlement called Posto Ricardo Franco. These actions resulted in the near extinction of the Kanôc tribe. The ethnocide of the Yanomami has been well documented; there are an estimated nine thousand currently living in Brazil in the Upper Orinoco drainage and a further fifteen thousand in Venezuela. The NGO Survival International has reported that throughout the 1980s up to forty thousand gold prospectors entered Yanomami territory bringing diseases the Yanomami had no immunity to , the prospectors shot them and destroyed entire villages, and Survival International estimates that up to twenty per cent of the people were dead within seven years. The Uru-Eu-Wau-Wau, whose territory has been protected by law since 1991, saw an influx of an estimated 800 people in 2007. The tribal leaders met with the civil authorities and demanded the trespassers be evicted. This tribe, initially contacted in 1981, saw a severe decline in population after disease was introduced by settlers and miners. Their numbers are now estimated at a few hundred. Portuguese colonization. During the Portuguese colonization of  the Americas, Cabral made landfall off the atlantic coast. Over the following decade the indigenous Tupí, Tapuya and other tribes which lived along the coast suffered large depopulation due to disease and violence. A process of miscegenation between Portuguese settlers and indigenous women also occurred. It is estimated that of the 2.5 million indigenous peoples who had lived in the region which now comprises Brazil, less than 10 per cent survived to the 1600s. The primarily reason for depopulation was diseases such as smallpox that advanced far beyond movement of European settlers. State reaction. In 1952 Brazil ratified the genocide  convention and incorporated into their penal laws article II of the convention. While the statute was being drafted, Brazil argued against the inclusion of cultural genocide, claiming that some minority groups may use it to oppose the normal assimilation which occurs in a new country. According to professor of law at Vanderbilt University Larry May, the argument put forward by Brazil was significant, but cultural genocide should not be cast aside, and this type of genocide should be included within the definition of genocide. In 1967 public prosecutor, Jader de Figueiredo Correia, submitted the Figueiredo Report to the dictatorship which  was then ruling the country. The report, which ran to seven thousand pages, remained hidden for over forty years. Its release caused an international furore. The rediscovered documents were examined by the National Truth Commission, which was tasked with the investigations of human rights violations which occurred in the periods 1947 through to 1988. The report reveals that the SPI had enslaved indigenous people, tortured children and stolen land. The Truth Commission was of the opinion that entire tribes in Maranhão were completely eradicated and in Mato Grosso, an attack on thirty Cinturão Largo left only two survivors (the "Massacre  at 11th Parallel"). The report also states that landowners and members of the SPI had entered isolated villages and deliberately introduced smallpox. Of the one hundred and thirty four people accused in the report the state has as yet not tried a single one. The report also detailed instances of mass killings, rapes, and torture. Figueiredo stated that the actions of the SPI had left the indigenous peoples near extinction. The state abolished the SPI following the release of the report. The Red Cross launched an investigation after further allegations of ethnic cleansing were made after the SPI had been  replaced. In 2014, Volume II, Chapter 5 of the official Report of the National Truth Commission acknowledged the deaths of at least 8,000 indigenous people during the period under investigation and made 13 recommendations to redress the situation, beginning with a public apology from the Brazilian State to the indigenous peoples, and including "creation of a specific truth commission for indigenous issues; a commemorative date for the events that occurred; the creation of museums; production of didactic and audiovisual material to be shared in schools, on television, and on the internet; the implementation of actions to preserve the culture of  indigenous peoples; delivery of all kinds of documents from the dictatorship to these peoples; and the return of territories taken from them". Few, if any, of these recommendations have been implemented. In 1992 a group who had been prospecting for gold were tried for the attempted genocide of the Yanomami tribe. A report from an anthropologist, which was submitted as evidence during the trial, stated that the prospectors' entry into Yanomami territory had an adverse effect on their lives, as the prospectors carried diseases. They had also contaminated the rivers which the Yanomami used as a source of food. The  UN reported that thousands of the Yanomami have been killed as the Brazilian government failed to enforce the law and that, even after though the Yanomami peoples' territory had been demarcated, the state had not provided the necessary resources to stop the illegal incursion of gold prospectors. These prospectors have caused massive forest fires which have led to the destruction of extensive areas of both croplands and rainforest. International reaction. At the 1992 Earth Summit in Brazil the Kari-Oka Declaration and the Indigenous Peoples Earth Charter were presented by the representatives of indigenous peoples from around the world. The  Kari-Oka Declaration states "We continue to maintain our rights as peoples despite centuries of deprivation, assimilation and genocide". The declaration also asserted that the genocide convention must be amended so as to include the genocide of indigenous peoples. The International Work Group for Indigenous Affairs (IWGIA) was founded in 1968 in response to the genocide of indigenous peoples in Brazil and Paraguay, and in 1969 Survival International was founded in London as a response to the atrocities, theft of land and genocide occurring in the Brazilian Amazon. In 1972 anthropologists from Harvard University founded Cultural Survival. The World Bank  has been subject to criticism over loans which have been used to help fund the dislocation of indigenous peoples and environmental destruction. The Polonoreste project caused wholesale deforestation, ecological damage on a wide scale, as well as the forced relocation of indigenous communities. The project led to an international campaign that resulted in the World Bank suspending loans.
