GIS-based site selection for agricultural water reservoirs: a case study of São...
Dziuba, Olga; Custódio, Cláudia; Silva, Carlos Otero; Granja Martins, Fernando Miguel; Lança, Rui; Maria Neto Paixão Vazquez Fernandez Martins, HelenaIn the São Brás de Alportel municipality, water scarcity poses a significant constraint on agricultural activities. This study utilises Remote Sensing (RS) and Geographical Information Systems (GISs) to identify existing irrigated areas, delineate catchment basins, and select the most suitable sites for the installation of new surface water reservoirs. First, the principal territorial components were characteri...
Evaluation of the impact of sustainable drainage systems (SuDSs) on stormwater ...
Araújo, Suelen; Lança, Rui; Silva, Carlos Otero; Torret, Xavier; Granja Martins, Fernando Miguel; Maria Neto Paixão Vazquez Fernandez Martins, HelenaTo mitigate the impacts of urbanisation and the attendant surface sealing, appropriate measures are required when adapting urban spaces and drainage infrastructure. In this context, the deployment of Sustainable Drainage Systems (SuDSs) has emerged as a viable alternative, delivering highly positive outcomes by enhancing hydrological, hydraulic and landscape performance while restoring ecosystem services to the...
Sustainable competitiveness of tourism in the Algarve region. Critical stakehol...
Farinha, Fátima; Bienvenido-Huertas, David; Duarte Pinheiro, Manuel; Da Silva, Elisa Maria De Jesus; Lança, Rui; Oliveira, Miguel José; Batista, RicardoThe Algarve region, located in the south of Portugal, is a well-known tourism destination that seeks to be sustainable and competitive. The local administration looks to establish a collaborative network, where stakeholders take a crucial role. The research aims to appeal to the accommodations and food services stakeholders to have a shared vision of the issues and priorities related to sustainable tourism deve...
Applying remote sensing technologies in urban landscapes of the Mediterranean
Pedras, Celestina M.G.; Fernandez, Helena Maria; Lança, Rui; Granja-Martins, FernandoThere has been increasing pressure on water resources in cities due to the proliferation of urban green areas. In the Mediterranean climate, only a small part of the plants’ water needs is supplied by rainfall during the winter months. Thus, in Algarve (Portugal) irrigation of the urban landscapes is required almost all year round. The aims of this study were to evaluate the maintenance of the urban landscapes ...
Comparison of artificial intelligence algorithms to estimate sustainability ind...
Bienvenido-Huertas, David; Farinha, Fátima; Oliveira, Miguel José; Da Silva, Elisa Maria De Jesus; Lança, Ruithe monitoring of sustainability indicators allows behavioural tendencies of a region to be controlled, so that adequate policies could be established in advance for a sustainable development. However, some data could be missed in the monitoring of these indicators, thus making the establishment of sustainability policies difficult. This paper therefore analyses the possibility to forecast the sustainability in...
Selection process of sustainable indicators for the Algarve Region—OBSERVE Project
Farinha, Fátima; Oliveira, Miguel José; Da Silva, Elisa Maria De Jesus; Lança, Rui; Pinheiro, Manuel Duarte; Miguel, CátiaThe selection of indicators for the Observatory of Sustainability of the Algarve Region for Tourism (OBSERVE), poses challenges, namely which indicators are relevant to stakeholders and how to assure that information is available. To support the selection of the environmental, sociocultural, economic and institutional indicators, an engagement process was designed and applied, which included meetings with stake...

Impacto da carga combustível nas propriedades hidráulicas de um solo pós-incênd...
Soraia, Almeida; Martins, Fernando; Fernandez, Helena; Pedras, Celestina M. G.; Lança, RuiO objetivo deste trabalho foi estudar o impacto da carga de combustível nas propriedades hidrológicas de um solo franco arenoso, queimado em condições de laboratório. Para tal, foram recolhidas e transportadas para laboratório, amostras de solo não perturbado, onde foram queimadas depois de aplicar diferentes cargas de material combustível (agulhas de pinheiro). A taxa de infiltração e a sorvidade do solo dimin...
Deteção remota aplicada à rega dos espaços verdes urbanos
Pedras, Celestina M. G.; Fernandez, Helena; Lança, Rui; Valín, I.; Da Silva, Elisa Maria De Jesus; Silva, Maria Rafaela; Lopes, G.; Rosa, H.A nova cultura da água visa a conservação dos recursos naturais e o aumento do rendimento produtivo da água nos espaços verdes públicos e privados. Estes espaços assumem uma relevância no bem-estar e na qualidade de vida das populações urbanas. No entanto, o aumento da área verde em climas mediterrâneos estará inevitavelmente associado ao aumento do consumo em água. A rega surge com a finalidade de fazer face à...
