A dissertação de mestrado intitulada "O uso do solo e os regimes de fogo entre 1975 e 2019, à escala da freguesia: Peravelha, Aldeia de Nacomba e Ariz, Ariz e Nacomba (Moimenta da Beira) e Alferce (Monchique)" analisa o uso do solo e os regimes de fogo em duas regiões distintas de Portugal ao longo de um período de 44
anos. O objetivo principal da pesquisa é compreender a relação entre o uso do solo nessas áreas e os padrões de incêndios florestais ocorridos entre 1975 e 2019. Para alcançar esse objetivo, foram recolhidos, compilados e analisados dados geoespaciais sobre o uso do solo e as ocorrências de incêndios nas freguesias estudadas,
usando um sistema de informação geográfica e o software ArcGIS. Foram considerados fatores como ocupação dos espaços florestais, matagais e áreas agrícolas e a ocorrências de incêndios. Em resultado disso, obteve-se conjunto de cartografia que espelha o padrão do uso do solo e do regime do fogo. A análise das áreas de estudo demonstra que a maior parte das áreas que sofrem queimadas é constituída por florestas e matagais, com algumas áreas agrícolas também afetadas. A evolução do uso e ocupação do solo é notável, com tendências distintas entre as áreas. Enquanto na freguesia de Alferce a percentagem de cobertura florestal
diminui e os matagais aumentam, na freguesia de Peravelha, Aldeia de Nacomba e Ariz ocorre o oposto, com aumento das áreas florestais e diminuição dos matagais. Em ambas as áreas, as áreas agrícolas diminuem. Notavelmente, nas áreas de estudo, as zonas com menor probabilidade de incêndio são as de pastagem, superfícies agroflorestais de sobreiro e territórios artificializados.
The master's thesis titled "Land Use and Fire Regimes Between 1975 and 2019, at the Parish Scale: Peravelha, Aldeia de Nacomba and Ariz, Ariz and Nacomba (Moimenta da Beira), and Alferce (Monchique)" analyzes land use and fire regimes in two distinct regions of Portugal o a period of 44 years. The main research objective is to understand the relationship between land use in these áreas and patterns of forest fires that occurred between 1975 and 2019. To achieve this goal, geospatial data on land use and fire occurrences in the studied parishes were collected, compiled, and analyzed using a geographic information system (GIS) and ArcGIS software. Factors such as the occupation of forested spaces, shrublands, agricultural áreas, and fire incidents were considered. As a result, a set of cartography was generated that reflects the land use patterns and fire regime. The analysis of the study áreas demonstrates that most of the áreas affected by fires consist of forests and shrublands, with some agricultural áreas also affected. The evolution of land use and occupation is remarkable, with distinct trends between the áreas. While the percentage of forest co decreases and shrublands increase in the parish of Alferce, the opposite occurs in the parish of Peravelha, Aldeia de Nacomba, and Ariz, with an increase in forested áreas and a decrease in shrublands. In both áreas, agricultural áreas decrease. Remarkably, in the study áreas, the zones with a lower probability of fire are pasturelands, agroforestry surfaces with cork oak, and artificialized territories.
