SÃO PAULO, 9 May, 2017 − A recent violent attack on a group of indigenous people in the Amazon rainforest of northern Brazil is seen by environmentalists as a symptom of a new climate of hostility towards such groups, fuelled by conservative congressmen’s attempts to undermine land rights. As indigenous reserves, which occupy 23% of the greater Amazon region, are spaces where most of the rainforest is still intact, this represents a growing threat to the forest’s future – and therefore could impact on climate change. The attack, by farmers armed with guns, knives and machetes in the northern state of Maranhão left up to 13 Gamela Indians in hospital with bullet and knife wounds. The Gamela, who number about 1,200 people, have been occupying cattle farms established on what they claim is their traditional land. In the disputed areas, forest has been cleared and replaced with cattle pasture.
Rainforest preservation The attack is part of a disturbing trend in Brazil that indirectly threatens the preservation of large areas of the Amazon rainforest.
Satellite maps produced by ISA, an environmental NGO, clearly show the relation between indigenous areas and the preservation of the forest. The Indians preserve the forest because they need its natural resources. A 2014 study by Imazon, another Brazilian NGO, showed that in the Amazon region indigenous reserves accounted for under 2% of deforestation, while privately-owned areas accounted for 59%. Even in government-run conservation areas it was 27%, because of the frequency of illegal invasions by loggers and farmers. But by October 2016, satellite images from INPE, the Brazil Space Research Institute, that is responsible for monitoring the Amazon region, showed that deforestation in indigenous reserves had almost tripled, mainly due to illegal logging and invasions. INPE detected an overall increase of almost 30% in deforestation for the region. A study carried out in 2015 by IPAM, an NGO set up after the 1992 Earth Summit in Rio de Janeiro to produce scientific knowledge about the Amazon − found that the indigenous areas, estimated to contain 13 billion tonnes of carbon, will have avoided 431 million tonnes of carbon emissions between 2006 and 2020.“Forests maintained by the Indians function like natural air conditioning and as climate regulators of the region they are in”In addition to their role in absorbing carbon and their low rates of deforestation, indigenous areas have a healthy effect on their surrounding areas, according to IPAM researcher Paulo Moutinho. He says: “Forests maintained by the Indians function like natural air conditioning and as climate regulators of the region they are in.” Yet in spite of the obvious advantages of respecting indigenous areas, not just for their inhabitants but for the whole of Brazil and for the global climate, government and politicians seem more interested in clearing the forest for agricultural and mining projects. Sonia Guajajara, a co-ordinator at the Network of Indigenous Peoples in Brazil (APIB), says: “Although the whole world is discussing the reduction of deforestation to contain global warming, and Brazil has presented targets for reducing illegal deforestation, we are not even managing to do this. It is very worrying.” She blames the relaxation of environmental laws, the advance of agribusiness, the building of dams that lead to deforestation of large surrounding areas, and the government`s development policies, as well as an increase in illegal logging in the reserves.
