Optimisation of the geobiodiversity index for protected natural areas in northe...
Vieira, António; Steinke, Valdir; Bento-Gonçalves, António; Folharini, Saulo Oliveira; Novais, Jorge Leandro Ramalho; Silva, SaraMost studies on geodiversity and geoheritage have focused exclusively on analyzing and evaluating abiotic elements. Although some authors have emphasized the important links between abiotic and biotic elements, the focus has mostly been on abiotic elements alone and not on the interrelationship between the two. In this sense, our proposal is to analyze the potential of geodiversity in a broader sense. In other ...
Are beaches losing their capacity to receive holidaymakers? The case of Ofir, P...
Silva, Sara; Novais, Jorge Leandro Ramalho; Vieira, António; Marques, TiagoCoastlines are suffering from the effects of erosive processes, the decrease in sediment supply, the rise in mean sea level, and the construction of coastal infrastructure and drainage works, which are further exacerbated by global climate change. The area of the Parque Natural do Litoral Norte (North Coast Natural Park) reveals worsening erosion rates and the transformations directly affect the natural resourc...
Bibliometric analysis on wildfires and protected areas
Folharini, Saulo Oliveira; Vieira, António; Bento-Gonçalves, António; Silva, Sara; Marques, Tiago Ribeiro; Novais, Jorge Leandro RamalhoWildfire are increasingly frequent events on a planet undergoing climate change. With more favourable climate conditions for their occurrence, like prolonged periods of drought, the frequency and intensity of these catastrophes continue to increase. Protected areas are important territories for conserving ecosystems and biodiversity around the world and serve as a key management tool in national environmental p...
Aplicação de sistemas de informação geográfica e drones para análise da erosão ...
Novais, Jorge Leandro RamalhoNas últimas décadas, a migração das atividades humanas para as zonas costeiras aumentou significativamente, não só em Portugal, mas em todo o planeta. Nalguns locais, a fixação das atividades antrópicas levou ao aumento da construção no interior do sistema praia/duna e à fixação de mais população, aumentando a pressão humana sobre as zonas costeiras. Embora sejam uma transformação natural, os processos de erosã...
Soil erosion quantification using Machine Learning in sub-watersheds of Norther...
Folharini, Saulo Oliveira; Vieira, António; Bento-Gonçalves, António; Silva, Sara; Marques, Tiago Ribeiro; Novais, Jorge Leandro RamalhoProtected areas (PA) play an important role in minimizing the effects of soil erosion in watersheds. This study evaluated the performance of machine learning models, specifically support vector machine with linear kernel (SVMLinear), support vector machine with polynomial kernel (SVMPoly), and random forest (RF), on identifying indicators of soil erosion in 761 sub-watersheds and PA in northern Portugal, by usi...
