- Choosing the best socioeconomic nutrients for the best trees: a discussion about the distribution of Portuguese Trees of Public InterestPublication . Mourão, Paulo Reis; Martinho, VítorAround the world, there are several ecosystems, some in their initial conditions, which are unique and need preservation. This heritage needs adjusted management plans and con- servation attentions. It is important to preserve the natural heritage for the future genera- tions, creating active legislation, more governance, empowerment for the related institu- tions, and bringing more dynamics for these frameworks. However, the literature shows that these issues may be explored deeper. In this context, using data from the Portuguese Institute for Conservation and Nature, this work discusses the heterogeneous distribution of Trees of Public Interest (TPI) in Portugal. These trees are relevant for several criteria such as size, age, or cultural value. Through the use of Poisson, negative binomial, zero- inflated Poisson, and zero-inflated negative binomial regressions, several conclusions have been reached. Among these conclusions, it is highlighted that areas characterized by higher levels of touristic dynamism tend to increase the number of TPI. Higher percentages of for- estry area for intervention ensure at least one TPI. The age of the creation of the municipal- ity also significantly influences the risk of having no TPI.
- Circular Economy and Economic Development in the European Union: A Review and Bibliometric AnalysisPublication . Martinho, Vítor; Mourão, Paulo ReisIncreased changes in the climate and ecosystems call for a sustainable economic development, where economic growth should be compatible with the environment goals. In order to do this, it is urgent to find new ways of life and new production systems that make our ecological footprint compatible with global sustainability. The concept of the circular economy has brought relevant contributions to this problem. The central objective of the study presented here is to highlight the main insights presented through scientific literature about the concept of the circular economy within the European Union. In practice, the intention is to show what has already been done about this topic and what can/should be implemented in the future. To achieve these objectives, 144 articles were considered from the Web of Science (Core Collection) for the topics “circular economy” and “European Union”. These documents were, firstly, analysed through a proper literature review and later explored through bibliometric analysis, considering bibliographic data and the VOSviewer software. As the main findings have revealed, the increased importance of this concept within the European Union is recognized. However, this paper also identifies several challenges in the literature, namely the concentration of the identified publications in certain countries, organizations, and authors.
- Scoring the efficiency of Portuguese wine exports – an analysis recurring to Stochastic Frontier ModelsPublication . Mourão, Paulo Reis; Martinho, VítorO Vinho português é reconhecido como uma importante fonte de receitas económicas de base agrícola para Portugal. No entanto, as receitas deste produto diminuíram na maioria dos mercados estrangeiros na década 20012011. Neste artigo, iremos desenvolver uma tentativa original para identificar os determinantes mais importantes do valor das exportações de vinhos portugueses e os níveis de eficiência para cada país de destino. Os nossos resultados revelaram que o valor das exportações de vinhos portugueses tem uma relação positiva com o tamanho do setor público em cada país de destino, com a população rural do país de destino, e com o PIB real per capita, entre outras variáveis. A eficiência das exportações de vinho aumenta por causa do nível de inflação e do investimento direto estrangeiro per capita nas economias de destino. Também descobrimos que os destinos mais eficientes são aqueles onde o português é a língua nativa, e dois dos casos menos eficientes são a Polónia e os Estados Unidos da América, que são casos que merecem atenção especial por partedos exportadores portugueses.
