- Relationship between landscape pattern and human disturbance in Serbia from 2000 to 2018Publication . Quinta-Nova, L.C.; Naranjo Gómez, José Manuel; Vulevic, Ana; Castanho, Rui Alexandre; Loures, LuísThis study intends to verify how the alteration of the landscape configuration, represented by different metrics of configuration and diversity, is related to the intensity of human disturbance. The objectives of the study are: (1) to quantify the change in land use/land cover (LULC) patterns and the degree of human disturbance in Serbia between 2000 and 2018, and (2) to study the relationship between LULC configuration and the impact resulting from human disturbance under different levels of intensity, to understand how changing trends in landscape pattern can serve as indicators to estimate landscape changes resulting from human actions. The Hemeroby Index (HI) was calculated to quantify the impacts on ecosystems resulting from disturbance caused by human actions. Based on the analysis of the variation in the value corresponding to the HI for the period between 2000 and 2018, the level of naturalness increased by only 5% of the territory of Serbia, with this change being verified mainly in SE Serbia. The landscape pattern was quantified using a set of LULC metrics. We used the Spearman method to identify the existing statistical correlations between the geometric parameters of the landscape and the HIs values. At the landscape level, the Mean Shape Index, Edge Density, Mean Patch Fractal Dimension, and Shannon Diversity Index show a strong negative correlation with HI. This correlation suggests that landscapes with greater structural complexity are good indicators of low levels of hemeroby. At the class level, Edge Density and Mean Patch Size correlate significantly with the HI for artificial surfaces, agricultural areas, forests, and semi-natural areas.
- Sustainability Indicators in the Southwest of Iberian Peninsula. Highlighting the Euro-region EUROACE: The OTALEX-C Project.Publication . Castanho, Rui Alexandre; Ramírez, Beatriz; Cabezas, José; Fernández Pozo, Luis; Loures, Luís; Caballero, Carmen; Ceballos, Fernando; Carriço, Cristina; Batista, Teresa; Gomes, Carlos Pinto; Mendes, Paula; Quinta-Nova, L.C.; Naranjo Gómez, José ManuelEUROACE is the name given to the Euro-region covering Alentejo and Centro in Portugal and Extremadura in Spain, since the biophysical perspective, it is mainly characterized by the topography and climate of the southwest of the Iberian Peninsula. The evolution of these two variables have allowed developing a wide variety of soils and a considerable amount of their typologies diversity, as well. The OTALEX C Project team, a cooperation formed by the direct collaboration of Portuguese and Spanish entities creating an active cross-border cooperation (CBC) strategy, belonging to the three levels of administration: national, regional and local. Sharing common problems was enable to develop common solutions for the territories as the example of the OTALEX C Spatial Data Infrastructure (IDE OTALEX C) - a set of indicators that may contribute to the sustainability of the mentioned territory. Those indicators cover a lot of biophysical variables: hydrology, climate, soil, vegetation, and fauna, among many others. The criteria selection of such indicators was carried out taking into account the possibility of a constant updating on the EUROACE territory, as well as they adapting to the Sustainable Development Indicators (SDIs), which are used by the EU Sustainable Development Strategy (EUSDS). With the data collection procedure has been possible to relate soil, weather and vegetation, enabling to analyze issues regarding with the ecosystems functioning as well as their biodiversity and vegetal distribution on the soil, which along, with their structure shape the landscape, where the arboreal stratum constitutes one of they principal components. Major results show that those indicators are helpful tools for territorial management which favoring the conservation and sustainable development of the territories.
