- Accessibility and connectivity - Movement between cities, as a critical factor to achieve success on cross-border cooperation (CBC) projects. A European analysisPublication . Alexandre Castanho, Rui; Vulevic, Ana; Cabezas Fernandez, Jose; Fernandez-Pozo, Luis; Naranjo Gomez, Jose Manuel; Loures, LuisNowadays, cross-border cooperation (CBC) is an undeniable reality in the space encompassed between European borders. This contributes to economical and social sustainable development, as well as to cohesion for trans boundary areas, which include administrative and territorial units from neighboring countries. A correct conceptual basis for the methodological approach to connectivity lies in the fact that the development of transportation systems, as integrated networks at different scales, is deeply changing their operation and the way they induce urban and regional development patterns. Overloaded transport corridors in the context of changing transportation flows are becoming an important issue for accessibility, impacting CBC indirectly, but harshly. Different modes of transport create different patterns of accessibility, with different influence in CBC accordingly. Throughout the present research, CBC European case studies, where connectivity-movement between cities, has been identified as a key factor for their territorial success, were assessed, described and analyzed. In the period of 2001-2006, improvements and further imbalances have occurred in accessibility development across regions and modes. Some signs indicate that the core-periphery pattern is slowly changing which leads towards an upgrade on the accessibility of places, regions and cities.
- Accessibility dynamics and regional cross-border cooperation (CBC) perspectives in the portuguese—spanish borderlandPublication . Vulevic, Ana; Castanho, Rui Alexandre; Naranjo Gómez, José Manuel; Loures, Luis; Cabezas, José; Fernández-Pozo, Luis; Martín Gallardo, JoséAccessibility plays a major role in achieving sustainable transport, and therefore urban and regional sustainability. The urban public transport system promotes mobility and realizes a large part of urban movements. Moreover, improving accessibility in order to promote sustainable transport requires the application of new concepts and indicators as a powerful tool in the process of creating a balanced urban transport system. In this regard, one of the main goals of this research is to present an overview of the relevant accessibility indicators and assessment of accessibility in regional Cross-Border Cooperation (CBC) in order to transcendence challenges and obstacles for sustainable transportation in these regions along of Portuguese-Spanish border. This paper focuses on the accessibility of cross-border cooperation scenarios along the border regions of Alto Alentejo (Portugal) and Badajoz (Spain) where the Case Study Research Method (CSR) made it possible to recognize accessibility as a key factor in territorial success. Also, accessibility analysis can assess improvements as well as regional imbalances. In addition, this methodology can be used to identify missing links, which requires new investments enabling long-term sustainability.
- Political commitment and transparency as a critical factor to achieve territorial cohesion and sustainable growth. European cross-border projects and strategiesPublication . Castanho, Rui Alexandre; Vulevic, Ana; Naranjo Gomez, Jose Manuel; Cabezas, Jose; Fernandez-Pozo, Luis; Loures, Luis; Kurowska-Pysz, JoannaPolitical commitment and transparency have been previously identified as critical factors for territorial success, as well as factors which allow the achievement of stronger cohesion and sustainable growth of cross-border cooperation projects and strategies. The present study is aimed at a more thorough analysis of these factors. Throughout the analysis and assessment of the European CBC case studies, where political commitment has been defined as a critical factor, political and economic transparency plays a key role. This analysis, which incorporates public and technical opinions, provides a better comprehension on how these factors influence the European panorama. It includes the key messages for policy-makers when designing and implementing development strategies specifically tailored to the needs of these places.
- Relationship between landscape pattern and human disturbance in Serbia from 2000 to 2018Publication . Quinta-Nova, Luís; Gómez, José Manuel Naranjo; Vulevic, Ana; Castanho, Rui Alexandre; Loures, LuisThis 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.
