Soil is a key resource that provides the basis of food production and sustains and delivers several ecosystems services including regulating and supporting services such as water and climate regulation, soil formation and the cycling of nutrients carbon and water. During the last decades, population growth, dietary changes and the subsequent pressure on food production, have caused severe damages on soil quality as a consequence of intensive, high input-based agriculture. While agriculture is supposed to maintain and steward its most important resource base, it compromises soil quality and fertility through its impact on erosion, soil organic matter and biodiversity decline, compaction, etc., and thus the necessary yield increases for the next decades. New or improved cropping systems and agricultural practices are needed to ensure a sustainable use of this resource and to fully take the advantages of its associated ecosystem services. Also, new and better soil quality indicators are crucial for fast and in-field soil diagnosis to help farmers decide on the best management practices to adopt under specific pedo-climatic conditions. Conservation Agriculture and its fundamental principles: minimum (or no) soil disturbance, permanent organic soil cover and crop rotation /intercropping certainly figure among the possibilities capable to guarantee sustainable soil management. The iSQAPER project – Interactive Soil Quality Assessment in Europe and China for Agricultural Productivity and Environmental Resilience – is tackling this problem with the development of a Soil Quality application (SQAPP) that links soil and agricultural management practices to soil quality indicators and will provide an easy-to-use tool for farmers and land managers to judge their soil status. The University of Évora is the leader of WP6 - Evaluating and demonstrating measures to improve Soil Quality. In this work package, several promising soil and agricultural management practices will be tested at selected sites and evaluated using the set of soil quality indicators defined for the SQAPP tool. The project as a whole and WP6 in specific can contribute to proof and demonstrate under different pedoclimatic conditions the impact of Conservation Agriculture practices on soil quality and function as was named the call under which this project was submitted.

Water is now considered the most important but vulnerable resource in the Mediterranean region. Nev ertheless, irrigation expanded fast in the region (e.g. South Portugal and Spain) to mitigate environmental stress and to guarantee stable grape yield and quality. Sustainable wine production depends on sustain able water use in the wine’s supply chain, from the vine to the bottle. Better understanding of grapevine stress physiology (e.g. water relations, temperature regulation, water use efficiency), more robust crop monitoring/phenotyping and implementation of best water management practices will help to mitigate climate effects and will enable significant water savings in the vineyard and winery. In this paper, we focused on the major vulnerabilities and opportunities of South European Mediterranean viticulture (e.g. in Portugal and Spain) and present a multi-level strategy (from plant to the consumer) to overcome region’s weaknesses and support strategies for adaptation to water scarcity, promote sustainable water use and minimize the environmental impact of the sector.

The world distribution of cork oak Quercus suber and holm oak Q. rotundifolia is basically restricted to the western Mediterranean basin. These two evergreen oaks are the base of the Portuguese montado and the Spanish dehesa. This thesis aims to analyse how bird communities of the montado are influenced by management practices. We used different approaches to study this relationship, and to evaluate which features are responsible for species distribution in different typologies of montado. First, we reviewed the concept of montado in order to better understand the system and to set thresholds on what can be considered as montado. Afterwards, we studied the elements that promote higher species diversity and individual species, or group of species, that can act as indicators of High Nature Value for montados. Finally, we evaluated how the bird communities are structured, and the influence of the main management actions (e.g. cattle and cork exploitation) on those communities; Resumo: A distribuição mundial do sobreiro Quercus suber e da azinheira Quercus rotundifolia é praticamente restrita à bacia do Mediterrâneo. Estas duas espécies de carvalhos são a base dos montados em Portugal e das dehesas em Espanha. No âmbito desta tese analisamos como as comunidades de aves do montado são influenciadas pela gestão florestal. Para este efeito usámos diferentes abordagens e avaliámos quais as características do montado responsáveis pela distribuição das espécies ao longo das suas diferentes tipologias. Fizemos uma revisão do conceito de montado e proposemos uma definição para o sistema, englobando a sua multifuncionalidade. Estudámos os elementos singulares que promovem a diversidade de aves e que podem ser simultaneamente indicadores de áreas de Alto Valor Natural (HNV). Por fim, avaliámos qual a influência da gestão (p. ex. pastoreio e descortiçamento) na estruturação das comunidades de aves.

Com a presente investigação pretendemos conhecer a vivência das emoções dos enfermeiros nos cenários da prestação de cuidados ao doente oncológico e simultaneamente contribuir para uma melhoria das práticas de intervenção e de gestão emocional em enfermagem nos contextos de trabalho em Oncologia, procurando dar resposta à pergunta inicial de investigação: Qual a vivência emocional dos enfermeiros nos cenários da prestação de cuidados ao doente oncológico? Nas opções metodológicas optámos pelo paradigma qualitativo, onde a entrevista narrativa foi a técnica privilegiada de recolha de informação, tendo permitido compreender com profundidade a forma como os enfermeiros vivem a prestação de cuidados ao doente oncológico. As experiências emocionais consideradas mais marcantes foram na generalidade aquelas que mais penosas se constituíram para os entrevistados, relacionadas com uma relação mais próxima e profunda com o doente e com situações de morte e sofrimento. Consequentemente os sentimentos e emoções referidos foram na sua maioria negativa. Na prática de cuidar do doente oncológico verificou-se a influência marcada dos mitos sociais e pessoais associados à doença cancro, tendo sido reconhecida de forma global a complexidade e especificidade inerentes a esta prestação de cuidados, tão gratificante, quanto desgastante. O uso de mecanismos de gestão das experiências emocionais refletiu-se no recurso a estratégias pessoais e externas, usadas na sua maioria com o objetivo de o desgaste emocional. Foram sugeridas várias medidas de intervenção organizacional no reconhecer uníssono da necessidade de acompanhamento e suporte por parte da organização de saúde. Os resultados desta investigação acrescentam assim todo um conjunto de novos dados que ajudam na compreensão da problemática da vivência emocional dos enfermeiros, na certeza de que esta melhorará a prestação de cuidados ao doente oncológico, com consequente otimização organizacional. /ABSTRACT - With this present investigation we intend to study the emocional life of nurses while providing health care to oncological patients and simultaneously contribute to an improvement of the intervention and emotional management practices in nursing in the contexts of working in Oncology, trying to answer the initial question of the inquiry: What is the emotional life of nurses in health care scenerjy to oncological patients? As far as the methodology is concerned we chose the qualitative paradigm, in which the narrative interview was the privileged technique to gather information. That allowed us to deeply understand the way nurses live the providing of health care to the oncological patient, their emotional experiences, what they feel and express, what moves and consumes them, as well as the forms of emotional management. The most striking emotional experiences have, in general, been those considered most painful by the interviewed nurses, usually related to a closer and deeper relation with the patient and situations of death and suffering. The consequent feelings and emotions have been mostly negative. Health care provided to oncologic patients is strongly influenced by social and personal myths related to cancer and both the complexity and specificity inherent to this kind of health care has been acknowledged as rewarding, as consuming. The use of means of emotional management is visible in the resource to personal and external strategies, used to diminish the emotional consumption. They have also suggested some measures of organizational intervention in the unison recognition of the need of accompaniment and support from the health care institution. The results of this investigation, thus add whole a set of new data that helps in the understanding of the problematic of the emotional life of nurses, in the certainty that this will improve the providing of care to the oncolologically sick person, with consequent organizational optimization.
