Análise temporal das mudanças no uso do solo e influência na Temperatura de Superfície Terrestre na bacia do rio Revuboe, Moçambique

Abstract

This research aims to analyze land use and land cover changes and their influence on land surface temperature in the Revuboe River Basin, Mozambique, over the period from 2005 to 2023, through the application of remote sensing techniques and Geographic Information Systems (GIS). The research addresses a gap in environmental studies applied to the region, while providing technical and scientific support for sustainable territorial planning. The work is structured into three main chapters, in addition to the introduction and final considerations: Chapter I – literature review: presents a theoretical and conceptual discussion on land use and land cover changes, relating them to environmental and climatic effects, with particular emphasis on land surface temperature. It also discusses the fundamentals of remote sensing, its relevance in environmental analysis, and the contributions of different studies carried out in national and international contexts. Chapter II – Temporal analysis of land use and land cover changes: examines the temporal dynamics of land use and land cover, mapping and quantifying the main land use classes in the Revuboe River Basin for the years 2005, 2009, 2015, 2020, and 2023. Chapter III – Relationship between Land Use Changes and Land Surface Temperature: focuses on the analysis of the relationship between land use/land cover changes and land surface temperature, describing the spatial and temporal variability of surface temperature and establishing its correlation with landscape transformations. Overall, the dissertation demonstrates that land use transformations in the Revuboe River Basin, driven by agricultural expansion, urban growth, and mining activities, have caused significant changes in the surface thermal regime, contributing to the intensification of environmental degradation processes and microclimatic impacts. The findings provide technical-scientific support for decision-makers and policymakers, guiding environmental monitoring strategies, impact mitigation, and the promotion of land use practices more closely aligned with sustainability principles.
