  • Competitiveness of portuguese montado ewe production systems among the european ewe production systems
    Publication . Ferreira da Silva da Costa Freitas, Maria de Belém; Ventura-Lucas, Maria Raquel; Izquierdo, Lola; Deblitz, Claus
    The number of ewes in Portugal registers a decrease since 1998. This decrease is felt particularly in the south of the country, which concentrates almost half of the existing ewes, mainly for meat production. One of the most important ewe production systems is the Montado, a High Nature Value ecosystem, occupying ca. 1.2 million ha in Portugal. The competitiveness of this system among the European ewe production systems is an important issue for the future of the Montado ecosystem. So, the objective of this paper is to analyze the ewe production systems in the Montado, using the agri benchmark database, and compare these systems with other European countries’ systems, ranking their competitiveness and e_ciency among other systems in the European Union. We concluded that this methodology facilitated an in-depth understanding not only of the competitiveness and e_ciency of ewe production systems in Portugal but also of their positioning regarding other systems in the European Union. The pattern of returns assures that these farms are competitive in the sense that they depend on the market on their decisions, and thus it is important that market values sheep products. Nevertheless, the diversification to other income sources would be a good option for the future sustainability of these farms and the opportunities and risks that these systems will deal with in a new green economy, with probable new functions and new opportunities for land, will be a challenge for the future.

  • Physiological and psychological benefits of exposure to nature during work in a military bunker—a pilot experimental study
    Publication . Silva Fernandes, Maria Jacinta; Bento, Ana Teresa; Gonçalves, Gabriela; Campos, Clarice
    The present controlled experimental research addresses the effects of exposure to nature on workers’ well-being and job performance in a work-confined setting. Ten individuals working in an open-space office inside a Portuguese military bunker were exposed to simulated nature (audio sounds and/or video images of nature). Quantitative physiological (heart rate) and self-reported measures (perceived positive and negative emotions, environment restorativeness, and work performance) were taken. Results indicate that exposure to nature during working time in confined places, through simulating a window with a view of nature and/or by introducing sounds of nature, promotes physiological and emotional well-being at work (heart rate significantly decreases, positive emotions significantly increase, and negative emotions decrease), and significantly increases employees’ perception of workplace restorative qualities. The results on work performance were non-significant. The present findings contribute to the evidence of the restorative effects of nature exposure during work. The research bridges a gap by considering workplaces where real nature exposure is not feasible and examining the evidence on the beneficial biophilic interventions (the restorative effects of simulated nature) within confined environments. The strategy to use videos and audio of nature may improve the structural conditions of work, benefiting well-being in these types of work settings.

  • Tracking tourism waves: insights from automatic identification system (AIS) data on maritime–coastal activities
    Publication . Ramos, Jorge; Drakeford, Benjamin; Costa, Joana; Madiedo Camelo, Ana Maria; Leitão, Francisco
    Abstract: The demand for maritime–coastal tourism has been intensifying, but its offerings are sometimes limited to a few activities. Some of these activities do not require specific skills or certifications, while others do. This study aimed to investigate what type of activities are carried out by tourism and recreational vessels in the coastal area of the central Algarve (Portugal). To this end, data from the automatic identification system (AIS) of recreational vessels was used to monitor and categorise these activities in a non-intrusive manner. A model (TORMA) was defined to facilitate the analysis of AIS data and relate them to five independent variables (distance from the coast, boat speed, bathymetry, seabed type, and number of pings). The results of the analysis of more than 11 thousand hourly AIS records for passenger, sailing, and charter vessels showed that the 14 most regular ones had strong seasonal patterns, greater intensity in summer, and spatial patterns with more records near some coastal cliffs. This study provides valuable information on the management of motorised nautical activities near the coast and at sea, contributing to more informed and effective tourism regulation and planning.
