%X The opening of the BR-174 highway, linking Manaus (Amazonas) to the state of Roraima, enabled the human occupation of distant regions of the big rivers. On attracting people arises Community Boa União on the banks of Balbina Reservoir. The aim of the study was to assess the environmental conflicts in the basin Boa União (12,288 ha), in relation to the drainage system and slope with land use. The methodology consisted of field work, preparation of maps and data analysis. The field work was carried out to recognize the área (20 October 2015), raise data usage of land and conflicts and apply qualitative questionnaire, along with community residents. Hypsometric, slope and land use/cover maps were elaborated by SPRING software, using Aster (three dimensional) and Landsat 8 Oli (11 September 2015). The watershed Boa União has a slope of 13.9 ± 9.9 % and 61.4 ± 16.8 m of altitude, featuring a flat relief corrugated. Land use/cover consisted in forests (58 %), agriculture (19 %), water (20 %) and exposed soil (3 %). Agricultural class and exposed soil mainly occupied flat areas of the watershed, while water class was represented by Balbina Reservoir. Agriculture is also the cause of environmental conflicts because not respect the banks of watercourses (Permanent Preservation Areas). Additionally, the islands were occupied by agriculture, expanding conflict. Residents of the community recognize the importance of environmental preservation, but depend on the conflicting areas, the drought has suffered consequences such as difficult access to crops and the shortage of fish.
