promise to invest R$3.700 billion (1,300 million GBP) into various issues. IBAMA report The IBAMA's environmental impact assessment has listed the following possible impacts: The generation of expectations towards the future of the local population and indigenous people; An increase in population and uncontrolled land occupation; An increase in the needs of services and goods, as well as job demand; A loss of housing and economic activities due to the transfer of population; Improvements on the accessibility of the region; Changes in the landscape, caused by the installation of support and main structures for the construction of the dam; Damage to the archaeological estates in the area; Permanent flooding of shelters in Gravura Assurini; However, a clarification was released by the Brazilian authorities, in which it was deemed that the assured social and economic benefits, considered for the environmental redesign and the region's infrastructural developments, would outweigh the expected environmental damage. Since the beginning of the project many environmental and human rights organizations have been protesting against the construction of the Belo Monte Dam. On 14 August 2012 the Brazil Federal Court halted the construction of the Belo Monte Dam on the basis that the government's authorization of the dam was unconstitutional. The government didn't hold constitutionally required meetings with indigenous communities affected by the dam before granting permission in 2005 to start with the construction. This is against the Brazilian law and international human rights. However, Norte Energía, the company assigned with the construction of the Belo Monte Dam, has the possibility of an appeal to the Supreme Court. Human rights concerns The attitude and treatment of the Brazilian government towards the affected indigenous groups is strongly criticised internationally. The UN Human Rights Council has published statements denouncing Brazil's careless construction methods, and the International Labour Organization (ILO) likewise pointed out that the Brazilian state was in violation of ILO conventions (particularly the Indigenous and Tribal Peoples Convention, 1989 No 169) – although mechanisms for international enforcement are lacking, and it would require a Brazilian court to apply the binding principles of the convention, which Brazil has ratified. Indigenous groups have questioned the government's actions over these events, but their situation remains ignored by the authorities, as shown with the May 2011 Xingu Mission report of the CDDPH (Conselho de Defesa dos Direitos da Pessoa Humana), of which several sections regarding accusations of human right violations were excluded by
