“…Finally, we highlight the need for future work considering ITs outside the Brazilian Amazon and deforestation in non-forest native vegetation. For example, the Cerrado, the second largest biome in Brazil, has a predominance of non-forest native vegetation and increasing deforestation rates 65 .…”

Studies showed that Brazilian Amazon indigenous territories (ITs) are efficient models for preserving forests by reducing deforestation, fires, and related carbon emissions. Considering the importance of ITs for conserving socio-environmental and cultural diversity and the recent climb in the Brazilian Amazon deforestation, we used official remote sensing datasets to analyze deforestation inside and outside indigenous territories within Brazil's Amazon biome during the 2013–2021 period. Deforestation has increased by 129% inside ITs since 2013, followed by an increase in illegal mining areas. In 2019–2021, deforestation was 195% higher and 30% farther from the borders towards the interior of indigenous territories than in previous years (2013–2018). Furthermore, about 59% of carbon dioxide (CO2) emissions within ITs in 2013–2021 (96 million tons) occurred in the last three years of analyzed years, revealing the magnitude of increasing deforestation to climate impacts. Therefore, curbing deforestation in indigenous territories must be a priority for the Brazilian government to secure these peoples' land rights, ensure the forests' protection and regulate the global climate.

“…The increase in the indigenous people's purchasing power, assisted by social programs such as Bolsa Família and Bolsa Escola marks this period. This decade is also remembered for the intense conflicts with the city dwellers of Amarante do maranhão, as well as the increasingly dramatic changes in their ways of life, driven, above all, by the environmental degradation of the Indigenous Lands in the Amazon (Silva et al, 2021). Packaging of different products, plastic bags, household appliances, motorcycle parts, bicycles, PET bottles, satellite dishes, glass, iron, and aluminum accumulated in the back of the houses or less busy places in the village.…”

The volume of solid waste that accumulates in Indigenous Lands in the Amazon today increases the ecological and political problems of the indigenous peoples, requiring reflection and action against garbage coming from urban areas. This article aims to describe how the Gavião people deal with the garbage discarded within the Governor Indigenous Land, identifying management practices and classification schemes according to the Gavião. Over 60 years of disposal in the Governor Indigenous Land, waste has been linked to periods of proximity and distance from the urban centers, requiring specific management practices. The categories 'poisonous waste', 'dangerous waste', and 'our waste' indicate dimensions of agency present in the waste, and imply different ways of dealing with each waste. Reflecting on different human abilities in dealing with waste enables us to take a new look at our problems with petroleum derivatives and human life on the planet.

“…The collection of O. modestia confirms that the distribution of Saturniidae is still poorly known in the cerrado, partly due to the reduced sampling effort, as reported for new records of species of this family in this biome (Camargo, 2004). The Cerrado occupies 65% of the Maranhão state, but with 20% deforested (Silva Junior et al, 2018;Silva Junior et al, 2021). This can reduce the reproduction and survival of O. modestia, whose host plants are of the Rubiaceae family, such as Alibertia concolor, Alibertia edulis, Genipa americana and Tocoyena formosa (Diniz et al, 2013;Diniz et al, 2001;Mejia et al, 2020).…”
