This communication will be presented rehabilitation examples of megalithic monuments resulting from over 30 years of archaeological investigations carried out in northern Alentejo (Portugal). Being the oldest megalithic structures monumental architectural buildings of humanity pathologies that present are multiple and very different from each other. Typically, the recoveries of these structures have to be preceded by an archaeological nature of action to identify and recognize the best solutions for their preservation. Thus, this communication will present the results of the work carried out in different dolmens and menhirs, with timelines ranging from the 6th and 3th millenniums before Christ.

Judeus e muçulmanos vivem e movem-se numa sociedade que se define como uma “respublica christiana”. O direito canónico e a sua influência nas leis gerais dos reinos europeus implica, necessariamente, a construção de uma identidade cristã que se define em oposição ao “outro”, sobretudo o judeu, mas também o muçulmano. Neste sentido, a superioridade cristã, basilar no pensamento da Igreja, afeta a legislação régia portuguesa (como a demais europeia), criando progressivamente normas de segregação, tanto a nível de vestuário como de restrição espacial das minorias. O discurso da Igreja e o conceito de “infiel”, conflui, de resto, com os interesses das oligarquias concelhias, no seu programa político de hierarquização social e económica. Não obstante, os contextos vivenciais específicos de cada comunidade subvertem, bastas vezes, as normativas , numa necessária complementaridade dos membros das três religiões.

In 2014, Portugal was the seventh largest pellets producer in the World. Since the shortage of raw material is one of the major obstacles that the Portuguese sellets market faces, the need for a good assessment of biomass availability for energy purposes at both country and regional levels is reinforced. This work uses a Geographical Information System environment and remote sensing data to assess the availability and sustainability of forest biomass residues in a management unit with around 940 ha of maritime pine forest. The period considered goes from 2004 to 2015. The study area is located in Southwestern Portugal, close to a pellets factory; therefore the potential Contribution of the residual biomass generated in the management unit to the production of pellets is evaluated. An allometric function is used for the estimation of maritime pine above ground biomass. With this estimate, and considering several forest operations, the residual biomass available was assessed, according to stand composition and structure. This study shows that, when maritime pine forests are managed to produce wood, the amount of residues available for energy production is small (an average of 0.37 t ha -1 year -1 were generated in the study area between 2004 and 2015). As a contribution to the sustainability of the Portuguese pellets industries, new management models for maritime pine forests may be developed. The effect of the pinewood nematode on the availability of residual biomass can be clearly seen in this study. In the management unit considered, cuts were made to prevent dissemination of the disease. This contributes to a higher availability of forest residues in a specific period of time, but, in the medium term, they lead to a decrease in the amount of residues that can be used for energy purposes.

Solar radiation data is crucial for the design of energy systems based on the solar resource. Since diffuse radiation measurements are not always available in the archive data series, either due to the inexistence of measuring equipment, shading device misplacement or missing data, models to generate these data are needed. In this work, one year of hourly and daily horizontal solar global and diffuse irradiation measurements in Évora are used to establish a new relation between the diffuse radiation and the clearness index. The proposed model includes a fitting parameter, which was adjusted through a simple optimization procedure to minimize the Least Square Error as compared to measurements. A comparison against several other fitting models presented in the literature was also carried out using the Root Mean Square Error as statistical indicator, and it was found that the present model is more accurate than the previous fitting models for the diffuse radiation data in Évora.

Solar resource assessment is essential for the different phases of solar energy projects, such as preliminary design engineering, financing including due diligence and, later, insurance phases. An important aspect is the long term resource estimation. This kind of estimation can only be obtained through the statistical analysis of long-term data series of solar radiation measurements, preferably ground measurements. This paper is a first step in this direction, with an initial statistical analysis performed over the radiation data from a national measurement network, consisting of eighty-nine meteorological stations. These preliminary results are presented in figures that represent the annual average values of Global Horizontal Irradiation (GHI) and its Variability in the Portuguese continental territory. These results show that the South of Portugal is the most suitable area for the implementation of medium to large scale solar plants.

Neste trabalho de Projeto efetua-se o desenvolvimento do tema da produção de Resíduos Urbanos (RU) no Alentejo Central, utilizando-se o modelo DEA (Data Envelopment Analysis) para a análise das metas da recolha seletiva estabelecidas para 2020. Genericamente, quanto maior é o grau de desenvolvimento económico de um território, maior é a taxa de urbanização e maior é também a quantidade de resíduos urbanos produzidos por habitante. O rendimento e a urbanização são variáveis altamente correlacionadas, quando aumenta o rendimento disponível e os padrões de vida, aumenta também o consumo de bens e serviços de modo correspondente, o que leva ao aumento da quantidade de resíduos gerados. Assim, tendo em conta os impactos locais que os RU abandonados trazem, e com o objetivo de quebrar o elo entre crescimento económico e os impactos ambientais associados à produção de resíduos, são implementadas, nos países com elevados níveis de desenvolvimento, políticas baseadas em modelos integrados de gestão de RU que permitem a recuperação, reciclagem e valorização dos materiais, reservando-se a eliminação (deposição em aterro) para frações não valorizáveis, o que gera empregos e riqueza. Em Portugal vigora o Plano Estratégico para os Resíduos Urbanos (PERSU 2020) que define objetivos e metas nacionais, nomeadamente a meta da recolha seletiva, estabelecendo para 2020 um quantitativo nacional mínimo a recuperar de 47 kg por habitante por ano. Deste modo, importa caracterizar, para o período de 2002 a 2012, como evoluiu a produção de RU em comparação com a evolução do PIB em Portugal. A análise foca-se então na produção de RU na região do Alentejo em particular no Alentejo Central que evidencia um elevado nível per capita em comparação com o resto do país, situando-se mesmo acima das regiões do grande Porto e Lisboa. São apresentadas possíveis razões para o registo destes elevados níveis de produção de RU não se conseguindo, no entanto, avançar com evidências. Como o modelo DEA é utilizado no PERSU 2020 para fundamentar a projeção das metas da recolha seletiva por sistema de gestão de resíduos urbanos, fez-se a sua reprodução, o que permitiu uma análise mais detalhada dos dados e o ensaio de novos resultados considerando, para além do nível de produção de RU, o numero de equipamentos de deposição de recolha seletiva como input do modelo; Abstract: Title of the report: Professional career. Emphasis on the analysis of urban waste production in Alentejo Central - Portugal and the use of the DEA in defining the separate collection target This professional report presents the theme of the Urban Waste (UW) production in Central Alentejo, using the DEA (Data Envelopment Analysis) to analyse the target set for selective collection in 2020. Generally, the higher the degree of economic development of a region, the greater the rate of urbanization and the greater also the amount of municipal waste produced per capita. The variables income and urbanization are highly correlated, if you have an increase in the disposable income and living standards, the consumption of goods and services will increase accordingly, which leads to the increase of the amount of produced waste. Thus, taking into account the local impact that the abandoned UW brings, and in order to break the link between economic growth and the environmental impacts associated with the production of waste, countries with high levels of development implement policies based on integrated UW management models that allow the recovery, recycling and valorisation of materials, restricting the disposal (landfill) to non-recoverable fractions, which creates jobs and wealth. Portugal established a national strategic plan for Urban Waste (PERSU 2020) which defines the goals and national targets, including the selective collection target stating for 2020 a minimum recover of 47 kg per capita per year. Then it is relevant to characterize and compare the evolution of UW production and GDP in Portugal for the period 2002 to 2012. The analysis then focuses on the production of UW in Alentejo, particularly in Central Alentejo region, which shows a high per capita level compared to the rest of the country, placed just above the Greater Porto and Lisbon region. Then we explore several possible reasons for this high level of UW production in this region, but none is successful in producing strong evidence. As the DEA is used in PERSU 2020 to support the projection of the selective collection targets for the municipal waste management systems, in this report we develop the model, which allowed access to the data and a more detailed analyse. Then we introduce and test a new input, the number of separate collection deposition equipment, which gives new results that are compared with the original ones.

This chapter reports on the Portuguese trial of the Environmental Rating Scale for Sustainable Development in Early Childhood (ERS-SDEC) scale which was carried out in the context of the initial training of pre-school teachers at the University of Évora and during their practicum in local pre-schools. The particular context of this trial in initial teacher education provides a particular focus on the professional development of the students, and the cooperating teachers provided by their engagement in a collaborative action-research project that was focused upon Education for Sustainable Development. After providing some Portuguese contextual elements related with ESD, we will report on the trial of the scale in Évora and its results in terms of improving the quality of classroom practices and students and teachers professional development provided by their participation in the project. Finally we will share some reflections on the project, the format and use of the scale and on some critical issues that we learned to be critical in terms of ESD in Early Childhood.

During its history, several significant earthquakes have shaken the Lower Tagus Valley (Portugal). These earthquakes were destructive; some strong earthquakes were produced by large ruptures in offshore structures located southwest of the Portuguese coastline, and other moderate earthquakes were produced by local faults. In recent years, several studies have successfully obtained strong-ground motion syntheses for the Lower Tagus Valley using the finite difference method. To confirm the velocity model of this sedimentary basin obtained from geophysical and geological data, we analysed the ambient seismic noise measurements by applying the horizontal to vertical spectral ratio (HVSR) method. This study reveals the dependence of the frequency and amplitude of the low-frequency (HVSR) peaks (0.2–2 Hz) on the sediment thickness. We have obtained the depth of the Cenozoic basement along a profile transversal to the basin by the inversion of these ratios, imposing constraints from seismic reflection, boreholes, seismic sounding and gravimetric and magnetic potentials. This technique enables us to improve the existing three-dimensional model of the Lower Tagus Valley structure. The improved model will be decisive for the improvement of strong motion predictions in the earthquake hazard analysis of this highly populated basin. The methodology discussed can be applied to any other sedimentary basin.

In this study, we considered earthquakes with a maximum observed intensity (MOI) Io≥V that occurred throughout the Portuguese mainland and its adjacent Atlantic region to produce the map of maximum intensities of Portugal. This map is based on a wide variety of historical and recent sources, including 175 earthquakes, over the period of 1300–2014. This MOI map allows the regions of high, medium, and low levels of seismic hazard to be highlighted. The entirety of Portugal has been affected by major seismic events, some of which have caused serious damage. In addition, offshore earthquakes have had significant impacts on the coastal cities located in the central and southern regions of the country. Because the southern region of mainland Portugal is more active than the northern region, the largest concentrations of events with Io≥VI are in the southern region, especially on the mainland near the city of Évora, in the Lisbon region, in the Lower Tagus Valley region, and along the Algarve coast, especially in the southwest region in Cape of São Vicente and the Gorringe Bank.
