- Local Housing Strategy: Analysis of Importance and Implementation in Machico Municipality, MadeiraPublication . Alves, Raul; Lousada, Sérgio; Cabezas, José; Gómez, José Manuel NaranjoThis article presents a detailed analysis of the local housing strategies (ELH) in the Mu nicipality of Machico, Madeira, examining the diagnosis of housing needs, proposed solutions, and projected goals for the future. In addition to addressing the rehabilitation of private and public hous ing and the increase in housing supply, the study also explores how ELH relate to the new generation of housing policies and the public support program for promoting housing solutions for vulnerable people. It is important to note that the implementation of ELH in Machico also has a positive impact on the local landscape and climate resilience, promoting the conservation of important forest areas for the production and management of natural resources.
- Land-Use Changes in Insular Urban Territories: A Retrospective Analysis from 1990 to 2018. The Case of Madeira Island—Ribeira BravaPublication . Lousada, Sérgio; Cabezas, José; Castanho, Rui Alexandre; Gómez, José Manuel NaranjoAs the main island of the Madeira Archipelago, Madeira is faced with a clear demand for more precise and specific planning policies, in order to respond to regional requests. Bearing in mind the urgency of this issue linked to the concept of sustainability, planning strategies must be based on and strengthened by several studies, with the most varied themes, as a way of incisively understanding the problem at hand. Based on tools such as GIS (geographic information systems), this study allows the analysis of variations and patterns of land use and occupancy in the municipality of Ribeira Brava, located on Madeira Island. In a comprehensive manner, the study allows us to highlight the stagnation of the urban fabric of the region and, on the other hand, the change in the dynamics of agricultural cultivation present in the county. In addition, this study highlights the change in the predominant native vegetation in the municipality between the years 1990 and 2018. It is still necessary to emphasize the worrying scenario with the loss of native vegetation due to human activity, which requires more emphatic monitoring by regional government actors to protect, preserve and conserve these landscapes, environments and ecosystems.
- 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.
- Interactions between surrounding landscape biodiversity and intermittent rivers in mediterranean environments – case study of the Caia RiverPublication . Kaletová, Tatiana; Raposo, Mauro; Pinto-Gomes, Carlos; Castanho, Rui Alexandre; Martin Gallardo, Jose; Loures, Luís; Castanho, Hermenegildo; Cabezas, José; Fernándes-Pozo, Luis; Naranjo Gómez, José Manuel; Lousada, Sérgio; Escórcio, PatríciaLandscape is a dynamic mosaic of various structures interacting together. Neglecting or overusing one part of this mosaic may boost up or damage the development of others. For instance, overgrazing may increase soil erosion process which may clog a river/stream. In this regard land use changes, climate change and landscape management may lead to increase the intermittency of the surface watercourses, as well as in the ecosystem services provided by riverscapes for humans. Therefore, the present research focus on the existing interactions between the Caia River, an intermittent river located in the Mediterranean region, and its surrounding agricultural and natural landscapes. The performed analyses considered the identification of the existing interaction between natural and agricultural landscapes with the Caia River defining the predictable ecosystem services provided by each element of the landscape and assessing the potential decrease of the ecosystem services provided in case of landscape changes, which according to the performed research might enclose significant impacts both in ecologic and socioeconomic terms.
- Hydraulic planning in insular urban territories: the case of Madeira Island—Ribeira BravaPublication . Lousada, Sérgio; Cabezas, José; Castanho, Rui Alexandre; Gómez, José Manuel NaranjoThe main objective of this study was to analyze the flood propensity of the main water course of Ribeira Brava drainage basin and, if necessary, to suggest two methodologies to mitigate the impacts, i.e., detention basin sizing and riverbed roughness coefficient adjustment. For the flood propensity assessment, geomorphological data obtained from the watershed characterization process was used through the SIG ArcGIS software and then used for the calculation of the expected peak flow rate for a return period of 100 years using the Gumbel Distribution. Finally, the drainage capacity of the river mouth was verified via the Manning-Strickler equation, with the purpose of establishing whether the river mouth of the watershed has the capacity to drain the entire volume of rainwater in an extreme flood event. In summary, the results indicate that the river mouth of the Ribeira Brava watershed does not have the capacity to drain the rain flow for the pre-established return period; therefore, the detention basin was sized using the Dutch Method and the Simplified Triangular Hydrograph Method, and the roughness coefficient was adjusted in order to ensure the increase in the river mouth’s drainage capacity.
- Land-use changes in the canary archipelago using the CORINE data: a retrospective analysisPublication . Naranjo Gómez, José Manuel; Lousada, Sérgio; Garrido Velarde, Jacinto Garrido; Castanho, Rui Alexandre; Loures, LuísThe relationships between territorial governance and the pursuit of sustainable development are evidenced to be critical. Exploratory tools, like Geographic Information Systems (GIS), enable us to comprehend the patterns, dynamics, and parameters of land-use changes over the years. The results from such studies could be used in the design of a sustainable territorial governance strategy. Contextually, a study has been conducted based on the changes that occurred in land uses in the Canary Archipelago in the years 1990, 2000, 2012, and 2018 using CORINE (Coordination of Information on the Environment) data. Even if most of the land uses have been stable over the analyzed period, the investigation shows a decrease in agricultural areas. By contrast, it is possible to verify an increase in semi-natural areas and urban agglomerations. Moreover, the authors believe that an assessment of the land-use changes on these ultra-peripheral areas will also enable us to disclose some obstacles and opportunities for sustained developmen.
- 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.
- The Importance of the Strategic Urban Rehabilitation Plan in the Sustainable Development of the Municipality of MachicoPublication . Alves, Raul; Lousada, Sérgio; Cabezas, José; Gómez, José Manuel NaranjoThrough the requalification of buildings, the improvement of public spaces and the reorganization of motorized and pedestrian circulation, success is achieved, and thus the trend of decay of the urban fabric is reversed, transforming and returning urban centers to the people. The Strategic Plan for Urban Rehabilitation of Machico is an important document for the sustainable development of the city, which will contribute to social harmony and the improvement of the people’s quality of life, reducing the environmental impact of human mobility, boosting the economy, and creating conditions for the usufruct of the city of Machico in terms of mobility. The current article arises with the main objective of analyzing the Strategic Plan for Urban Rehabilitation of the Municipality (PERU) of Machico, which is an essential tool for the sustainable development of Machico. It is also important to emphasize the dimension of PERU in local economic development, from the perspective of the real estate market and in public investment. The results obtained showed that the Municipality of Machico faces some challenges in the implementation of sustainable urban development programs, due to the recent financial and economic crisis, which could limit the existing funding to fund sustainable urban development programs. It is from this plan, from the solutions determined for the rehabilitation of the public space in terms of security and mobility, based on the urban operations that are being developed, that it will be possible to offer the population a sustainable future.
- Assessing land-use changes in european territories: a retrospective study from 1990 to 2012Publication . Gómez, José Manuel Naranjo; Loures, Luís Carlos; Castanho, Rui Alexandre; Cabezas Fernández, José; Fernández-Pozo, Luis; Lousada, Sérgio António Neves; Escórcio, PatríciaThe need to understand what land use is has motivated the development of programmes that aims to identify it and quantify it—CORINE Land Cover (CLC) in 1985. From this official and open geodatabase—through the using of geographic information system (GIS) tools—the amount of area established for each land use has been identified in all the 28 member states of the EU. This mostly corresponds to agricultural and forestry uses. Between 1990 and 2012, it was possible to determine countries with variable land use models such as Finland, Latvia, Portugal and Spain—the rest of the states presenting stable land use models. Additionally, some countries are characterized by the predomi nance of one or two land uses. Contextually, the proposal aims to develop a retrospective study regarding the land-use changes in the EU territories from 1990 to 2012, through the available tools such as CLC.
