Análise da evolução espaço-temporal do uso e cobertura da terra no médio Jaguaribe utilizando o Mapbiomas 9.0

Abstract

The sometimes hostile conditions of survival characteristics of the Semi-Arid Region of Northeast Brazil do not prevent the occupation and modification of this space by human beings. In this context, the creation of water reservoirs induces transformations in the landscape. The objective of the present study is to analyze the changes in land use and land cover in the Middle Jaguaribe sub-basin for the years 1993, 2003, 2013 and 2023, with the objective of observing changes concisely every decade. To this end, data obtained through remote sensing, available in collection 9.0 of the MapBiomas Brasil platform were used. Thus, maps and tables were developed that allowed the analysis of the change in the level of occupation of each class in relation to the area of the Middle Jaguaribe sub-basin. Through these products, it was possible to verify important changes, such as the decrease in the savanna formation in the region, the spatial variation of the water mirrors and the expansion of crops and urban centers.
