Temporal Analysis of Soil Occupation in Mucuri Watershed Between 1989 and 2015

Abstract

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.

Sentinel-2 imagery usage on environmental monitoring of land use and occupation in a microwatershed in Central Brazil

“…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.…”

“…Novais et al (2016),Radoux et al (2016),Wang et al (2018),Almeida et al (2020), andNguyen et al (2020) also stated the misclassification most common are related to the similarity of spectral signatures or ROI non-representative gathering.…”

Análise do processo de expansão urbana de Bragança Paulista: o uso e ocupação do solo em microbacias hidrográficas e as geotecnologias

“…As geotecnologias e os procedimentos de sensoriamento remoto e geoprocessamento trazem grandes benefícios para a identificação, caracterização e mapeamento dos diferentes tipos de uso e ocupação do solo. Além disso, eles se mostram ferramentas essenciais para compreensão de territórios cada vez mais complexos (PAVANIN et al, 2016;OLIVEIRA et al, 2008;ROMÃO;SOUZA 2011;ALMEIDA et al, 2020). Os resultados da quantificação dos mapas foram organizados no banco de dados da pesquisa, podendo ser utilizados para avaliações mais detalhadas (tabelas 1 e 2) sobre o processo de expansão urbana no município de Bragança Paulista.…”
