“…Most of the studies approach methodologies applying geotechnologies for resource investigations. However, these authors did not necessarily discuss their implicatures regarding sustainability (Lago et al 2012;Novais et al 2016;Borràs et al 2017;Freitas et al 2017;Almeida et al 2020) and others. Leopoldo et al (2020), nonetheless, have performed a mapping of the environmental vulnerability in the Nascentes do Rio Parnaíba National Park.…”

“…Similar results were related by Lago et al (2012) when they assessed land-use adequacy in this region in 2011. Novais et al (2016) classified land-use using MAXVER on Landsat imagery, and they obtained satisfactory results for a watershed in the Northwest of Brazil.…”

“…Data from orbital sensors portray spectral responses of targets on the Earth's surface (Jensen 2009). Moreover, land-use and occupation can assist the socioeconomic and environmental planning of a given region (Novais et al 2016). Remote Sensing (SR) technologies associated with Geographic Information Systems (GIS) have provided identification of potentially productive lands or those most susceptible to environmental degradation (Radoux et al 2016;Borràs et al 2017;Mylona et al 2018;Kobayashi et al 2019;Nguyen et al 2020;Leopoldo et al 2020).…”

In the last decades, sustainability concerns have increased the demand for projects and strategic plans that integrate economic and social aspects, reducing environmental impacts. In this sense, this study aims to monitor land-use adequacy in the Ribeirão Extrema microwatershed, Distrito Federal, based on cross-mapping between land-use and occupation in 2019 and agricultural aptitude map through Geographic Information Systems and Remote sensing. To this end, a hypsometric and thematic database was prepared for the region. Besides, we acquired an image from the Sentinel-2 orbital sensor of October 2019. The image was subjected to classification regarding land-use and occupation, using the MAXVER (maximum likelihood) algorithm. It was observed that 80% of use in 2019 was related to agricultural activities. Kappa index validation reached 81% accuracy. Based on the methodology, we identified 62.33% of agricultural activities occur into its capacity; 4.33%, were used above capacity, causing environmental degradation, especially in permanent preservation areas. The application of the technique was considered satisfactory because the adequacy of land-use in the studied microwatershed could be assessed in order to pursue sustainable development. Continuous analyzes can improve results.

Anthropogenic action has caused intense changes in land use and cover over the decades. Identifying and knowing these changes makes it possible to measure the impacts that can be generated as well as to identify patterns of the development of a particular region and the relationship between society and land use. Thus, it is intended to identify the changes made in the land use and occupation of the Mucuri river basin between 1989 and 2015. So, this study used remote sensing techniques and tools besides aerial photographs to map the region and to identify surface behavior. Within the Mucuri basin, the soil had been mostly occupied by classes of forest and agricultural area, consistent with the social and economic reality of the region over the last decades. The changes that have occurred indicate a reduction in water availability, growth in urban occupation and, in many cases, soil and vegetation cover deterioration.
