SUMMARY:

The study seeks to conduct an analysis of landscape through a geographic information system and contribute to actions involving territorial and environmental management and protection of indigenous peoples in voluntary isolation, carried out by the Huni Kuĩ people from Kaxinawa Indigenous Land of Humaita River and surrounding region, in the state of Acre, Brazil. The objective is to assess the effects of deforestation suppression, identify the intensity of fires, and check land use situation on the Indigenous Land’s landscape and its surrounding region, in a 10-km range, from 2008 to 2023. The landscapes in the region where the mentioned Indigenous Land is located suffer impacts and pressures related to deforestations, fires, and intense occupation in the surroundings. The study adopted methodological procedures that include geotechnology tools and GIS environment, geoprocessing techniques, and statistics to analyze the geographic information. As result, an amount of 7,798 hot spots were identified in the 10-km range of the surrounding, and a total of 394 hot spots in the Indigenous Land. In the Indigenous Land’s surroundings, the density of hot spots was concentrated in the northern and western boundaries, and 64% of them are in areas without discriminative study. In the most remote region, near the boundaries of other Indigenous Land, the very low number of hot spots led to a discussion on the probable presence of uncontacted indigenous settlements. Wilcoxon signed-rank test demonstrated that there is significant difference in deforestation rates between the “Indigenous Land” and the “Surrounding Area” (10 km), indicating that there is an inhibiting effect on deforestation in the Indigenous Land. For the surrounding area, deforestations reached 76.75 km², number 36 times higher than that of the Indigenous Land (2.14 km²), where settlements occurred for small traditional plantations and agroforestry units, represented by 0.2% of the Indigenous Land’s whole extension. Deforestations have converted forests into pasture areas for cattle raising with accumulation of 642.41 km² in 15 years, and 64% are concentrated in area without discriminative study. The advance of such pressures, in its turn, increases hunting by non indigenous in the Indigenous Land. Such information assists the Huni Kuĩ people in conducting strategic dialogue actions and awareness of neighboring populations regarding territorial and environmental management, natural resources management and use, and protection of uncontacted indigenous.
