  • Construction and application of a landscape dynamics assessment tool [Elektronski vir] : tese de doutoramento
    Machado, Rui
    Landscapes are shaped and influenced by a dynamic balance of ecological processes and anthropogenic activity. Substantial changes may disrupt the natural balance of ecosystems, jeopardizing their ... capacity to provide essential services for the population. Landscape changes, often measured via land cover variations, are pointed out as a major cause of biodiversity loss and, thus, a central topic in Conservation Biology. Some authors warned that key concepts like ‘habitat loss and fragmentation’ are often misused, causing misinterpretations and erroneous conclusions. The central aim of this work is to develop an analytical method of assessing landscape dynamics and a conceptual framework capable of clarifying the spatial patterns of land transformation. The conceptual framework, the associated terminology, and the method called Landscape Dynamic Typology, were developed based on the landscape composition and configuration variations. To complement and enhance the methodological approach, two tools were built: i) LDTtool, an ArcGIS toolbox and ii) LDT4QGIS, a group of scripts for QGIS. The tools’ multiple features and settings were demonstrated in illustrative examples and case studies as distinct as grasslands preservation in Slovenia, invasive plants removal in a mountainous Natura 2000 site, or the characterization of montado loss in Portugal. The use of these software by other authors in urban studies in places like Romania and Indonesia further attests to their usefulness and acceptance by the community. Both tools are freely available and can be adapted to fulfil analysts’ needs. New versions will be released whenever a relevant update or improvement is implemented. In specialized or in more comprehensive approaches, complementing or complemented by other software, Landscape Dynamic Typology has shown to be useful in analytical procedures involving land use or land cover changes. By allowing iterative simulations, assisting in change detection and in spatial pattern classification and visualization, it contributes to more informed decision-making.
