- Dynamics of the land use changes and the associated barriers and opportunities for sustainable development on peripheral and insular territories: The Madeira Island (Portugal)Publication . Castanho, Rui Alexandre; Lousada, Sérgio; Gómez, José Manuel Naranjo; Escórcio, Patrícia; Cabezas, José; Fernández-Pozo, Luis; Loures, LuísConsidering the complex dynamics, patterns, and particularities that peripheral and insular territories/regions present—e.g., as the fragility, they show to achieve a sustain able development and growth—a study that analyzes the land uses of this territories is seen as pivotal to identify barriers and opportunities for a long-term sustained devel opment. Contextually, a general analysis was carried out through case study research methods covering those territorial typologies of the insular territory of Madeira Island, Portugal. The study, which was carried out through GIS mapping tools, enabled us to identify the land use changes in the last decades over the territory—allowing to estab lish a relation and identification of the associated barriers and opportunities presented by the territories to face the emerging sustainable development challenges. The study reveals the evident limitations of “ultra-peripheral” territories not only by the physical spatial dimensions but also by the difficulty to reconvert land uses. Thus, the main actors and their policies over the territory are even more relevant and need to be conducted in a more reasonable way—considering the fragility of this regions; such actions present higher impact over the territory and over their inhabitants’ life’s quality standards and finally on the long-term sustainability.
- Modelação de sistemas de abastecimento de água. O caso de Ilha da MadeiraPublication . Lousada, Sérgio; Silva, Pedro Soares da; Castanho, Rui Alexandre; Naranjo-Gómez, José ManuelA temática da insuficiência de água disponível para con sumo é essencial no debate social devido à importância natural deste recurso e às previsões de aumentos exponen ciais demográficos, o que introduziu uma maior pressão sobre o ciclo deste recurso finito e essencial para a ma nutenção do equilíbrio natural. A infraestrutura respon sável pela sua distribuição deve ser concebida, mantida e explorada eficazmente. Este estudo aborda a modelação e a calibração digital desta tipologia de infraestruturas, recorrendo a um software da especialidade, aplicando-o a um caso prático: concelho de Câmara de Lobos, na Ilha da Madeira (Portugal). Através deste estudo e da análise do modelo foi possível verificar as elevadas perdas no sistema de distribuição, além das causas, i.e, elevadas pressões e velocidades a que estão sujeitas as componentes da rede, devido à orografia da ilha da Madeira.
