Uma das condições que mais influencia a competitividade entre instituições de ensino é a Qualidade. Sendo a sociedade cada vez mais exigente, é necessário medir e avaliá-la. A utilização de uma ferramenta de autoavaliação, desenvolvida ao nível da União Europeia, a Common Assessment Framework (CAF), que teve como modelo de origem o European Foundation for Quality Management (EFQM), veio permitir a medição da qualidade dos serviços prestados na administração pública. Este estudo apresenta os diversos aspectos referentes à temática da qualidade, o modelo CAF e os principais resultados obtidos num inquérito por questionário, junto dos alunos, colaboradores internos e gestores dos Serviços Académicos da Universidade de Évora, com o objectivo de avaliar o grau de satisfação com a qualidade do serviço prestado, o desempenho de todas as partes interessadas e, consequentemente, a sustentabilidade desse serviço. Desses resultados retiraram-se alguns pontos fortes, enunciaram-se diversos pontos fracos e evidenciaram-se sugestões de melhoria para o serviço em estudo. Neste sentido, este trabalho serviu de diagnóstico e apresenta uma ferramenta que permite aos Serviços académicos da Universidade de Évora conhecerem-se melhor e poderem mover-se no caminho da qualidade. ABSTRACT: One of the conditions that most influences the competitiveness among institutions of education is quality. As society increasingly demanding in terms of professional skills, it is necessary to measure and assess the quality of education, through continuous improvement to achieve excellence. Currently, the quality must be measured and seen as a competitive advantage. The use of a tool for self-evaluation of the quality, developed at EU level, the Common Assessment Framework (CAF) that has had its origin on European Foundation for Quality Management (EFQM), carne allow the measurement of quality of services provided to the clients, based on an internal guidance for quality in the organization and on the adoption of quality ratings as a routine in their work. This study presents the various aspects relating to the issue of quality and the Common Assessment Framework (CAF) and presents the main results obtained through a survey by questionnaire. These questionnaires were applied to the students, staff and internal managers from the Academic Services of the University of Évora with the aim of assessing the grade of satisfaction with the quality of the services provided, the performance of all interested parties and therefore the sustainability of this service in this institution of higher education. As results obtained on this research there are some strengths, several weaknesses and suggestions for improvement that can benefit the service under study. This work can be used as a diagnosis and gives a tool that allows Academic Services of the University of Évora know themselves better and to be able to move on the path of quality.

Greenhouse production is a very important activity in the West region of Portugal, with an area of approximately 800 ha where the regular production consists in two crops per year, one in winter-spring and the other in summer-autumn. Many growers are now prepared to better exploit market opportunities, since they know that the big export window opportunity is from June to September, when the production is difficult in other regions of south due to high temperatures. Grower’s use new and more productive varieties, either in soil or hydroponic systems, mostly in unheated greenhouses, naturally ventilated, and equipped with modern fertigation systems. Greenhouse production causes some environmental impacts due to the high use of inputs. Several improvements in technologies and crop practices may contribute to increase the use efficiency of resources, decreasing the negative environmental impacts. Greenhouse vegetable production in Northern EU countries is based on the supply of heating and differs significantly from the production system in the Southern EU countries. In the Northern countries, direct energy inputs, mostly for heating, are predominant while in the South the indirect energy input is also important, mainly associated with fertilizers, plastic cover materials and other auxiliary materials. The main objective of this work was to characterise the greenhouse production systems in the West region of Portugal, in order to evaluate the energetic consumptions (direct and indirect), the GHH emissions, the production costs and the farmer’s income. With this work the mostly important inputs were identified, allowing proposing alternative measures to improve efficiency and sustainability. All the data was obtained by surveys performed directly with growers, previously selected to be representative of the crop practices and greenhouse type of the region. However, more research should be performed in order to develop and to test technologies capable to improve resources use efficiency in greenhouse production.

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.
