“…According to Cardoso et al (2006), the slope influences the relationship between rainfall and runoff in a basin, especially due to increases in surface runoff speed and reductions in water infiltration into the soil. Therefore, the topography is a key factor in predictive erosion models, as it directly influences the rate and volume of surface runoff of rainwater (Claudino et al, 2018). Soil physical properties, such as texture, porosity, and density, are directly associated with erosive processes (Simonetti et al 2018) and hence sediment loading into watercourses.…”

River basin environmental diagnosis and monitoring are fundamental for water resource use and conservation plans, as these systems integrate different landscape elements and may undergo impacts and changes of different levels and scales. In this context, this work aimed to characterize the geospatial, morphometric, and environmental dynamics in the Mariana microbasin, in the municipality of Alta Floresta, to provide technical-scientific subsidies for environmental management and planning at a local and regional level. The microbasin was analyzed for morphometric, topographic, and land-use and cover parameters using geospatial data processed in a geographic information system. The microbasin is classified as fourth-order, has a network of 72 channels, and its relief is mostly flat and smooth wavy. Moreover, the soil is predominantly covered by agricultural lands, encompassing 70% of the area. This feature brings the need to adopt conservation practices for soil management. This study showed the need for continuous environmental monitoring programs and expansion of conservation actions in the studied area.

“…Conforme Gross, Santos e Pereira Filho (2016), avaliações sobre a declividade do terreno constituem-se em importantes instrumentos de apoio aos estudos sobre a potencialidade de uso agrícola e planejamento de uma determinada área. Conforme Claudino, Silva, Caioni, Silva, & Oliveira (2018) o uso de técnicas de geoprocessamento permite observar as mudanças de espaço e observar a variação das características do solo, em função da declividade e potencial de erodibilidade do solo.…”

Soil degradation caused by erosion is one of the biggest environmental problems. The Geographic Information System (GIS) QGIS and ArcGIS were used to prepare thematic maps. The average slope resulted in smooth wavy (42.1%), flat (27.8%), and wavy to strong wavy (19.9%) over the entire length of the sub-basin. Erodibility resulted in very high (41%) mainly in sectors with a predominance of Neossolos Quartzarênicos soils, on average (7.1%) in the South and Southwest and low (51.1%) of the area corresponding to the soil of the type Dystrophic Yellow Latosol. The expansion of the agribusiness associated with inadequate soil management in areas susceptible to erosion at BHRG can compromise long-term environmental, social, and economic sustainability. It is important develop suitable agricultural techniques appropriate to the soil to optimize its use and its sustainable production capacity.

This article results and dismembered the master's research on "environmental conflict and climate change under the gaze of peasant youths Poconé, Mato Grosso," aimed at understanding perceptions of youths on environmental conflicts and existing climate change on our traditional community Lady of Lourdes (known as Zé Alves) and the Remnant Quilombo community Orangery, both located in the municipality of Poconé, MT. In this plot also articulate reflections to understand the dilemmas of "getting in and out" experienced by youths since the peasant youths of both communities are being made invisible by agribusiness advances that transform natural goods resources, to meet the economic perspective, making it impossible to remain in the territories. The investigative proposition relied on the qualitative method, with the methodological tactics the Social Map. For information were conducted seven field work, two mapping seminars, twelve semi-structured interviews with the youths, besides secondary sources (reports, articles and census) of the surveyed communities. We understand that the rural-urban migration are mainly related to lack of education and job opportunities and income, as well as non-execution of public policies thought to this reality.
