DYNAMICS OF LAND COVERAGE, USE AND OCCUPATION IN THE MUNICIPALITY OF ILHÉUS, BAHIA, BRAZIL
Landscape; Sustainability; Multitemporal Analysis; Geoprocessing
The uncontrolled use of natural resources, degradation of urban and rural areas, without
the establishment of mitigation measures and the inadequate methodology of
conservation and land use, cause the acceleration of processes of environmental
degradation to occur. The objective of this work is to analyze the ecology of landscapes,
in a geographical and multitemporal approach. The municipality of Ilhéus is located in
the south of Bahia, approximately 454.4 km from the capital Salvador. It is internationally
recognized for its natural beauty and scenic potential, with emphasis on cocoa farming,
tourism, real estate projects and major engineering works, such as the East-West railway
and the Porto Sul intermodal system. For this work, data and information from the
historical series of the Mapbiomas project were used as a basis, including aerial
photographs of the Executive Committee of the Cocoa Crop Plan (CEPLAC) and
LANDSAT satellite images, in versions 5, 7 and 8 , from the SENTINEL 2-B satellite,
and more recently from CBERS - 4, integrated and processed in a Geographic Information
System environment through QGIS Software version 3.22.4 and ArcGis PRO. The
supervised classification allowed the multitemporal analysis of the study area, through
geoprocessing techniques and field activities. Understanding and monitoring land use and
land cover is fundamental for understanding patterns of space organization, for
sustainable planning of environments and definition of public policies. The aim of this
work is to present a socio-environmental diagnosis, identify public policies for
environmental issues in the municipality, contribute to studies of landscape
dynamics for sustainable planning of environments and definition of public policies.
