Geometries in Landscape Ecology
2006
Fernandes, João Paulo | Guiomar, Nuno | Soares, António P.
In the process of landscape characterization a diversified sets of geometries need to be considered. These geometries include Land Use geometry with its permanent shifting of the habitat mosaic, Natural Resources geometry depicting the available natural resources and their degree of affectation by land uses, as well as the manifold geometries associated with the different ecological patterns and processes in the landscape (target species, fragile areas, etc.) and Socio-Economical and Political geometries and how decision making at this level reflects in the other geometries. GIS spatial analysis and modelling allows the integration of these geometries with other variables, and allows the development of simulation models for the evaluation of alternative land use scenarios, assessing the sensitivity of biodiversity indicators within different scenarios, and the integrated evaluation of the effects of different development scenarios on biodiversity, economy and cultural aspects. Examples are given on the basis of an ongoing research on Large Scale Grazing Systems (LACOPE)
