- Avaliação da sustentabilidade das explorações agrícolas dos Países da União EuropeiaPublication . Dos Santos, Maria José Palma Lampreia; Mota, Manuel Gonçalves da; Silva, Emiliana Leonilde Dinis Gil Soares; Toste, Gisele EvangelhoA atividade agrícola europeia desempenha um papel importante na segurança alimentar europeia e mundial através da produção agrícola, do fornecimento e do comércio internacional. O principal objetivo deste artigo visa analisar a sustentabilidade agrícola dos vinte e nove Estados-Membros da União Europeia em termos económicos, ambientais, sociais e políticos. A informação e os dados provêm da base de dados da RICA (Rede Interna de Contabilidade Agrícola), da Comissão Europeia. A metodologia inclui a abordagem min-max e métodos de análise multivariada, nomeadamente, a Análise de Componentes Principais e a análise de Clusters. Os resultados confirmam três grupos de países europeus, concretamente os países da Europa de Norte e Europa Central; os Novos Estados-Membros e os países Mediterrânicos. Os resultados confirmam ainda que as empresas agrícolas europeias e os respetivos países apresentam níveis de sustentabilidade média. A principal conclusão confirma a importância da sustentabilidade enquanto ferramenta para ajustar de forma mais adequada as políticas agrícolas entre os Estados-Membros europeus.
- A multicriteria approach for sustainability of european agricultural firmsPublication . Dos Santos, Maria José Palma Lampreia; Mota, Manuel Gonçalves daThere has been an undeniable and remarkable performance of the global food system over the last fifty years. During this period, total food supply has increased almost threefold, whereas population has only done so in a twofold ratio, along with very significant shifts in diet related to economic development. European agricultural activity plays an important role in European and world food security through the agricultural production, supply and international trade. The main aim of this paper was an analysis analyses the agricultural sustainability of the twenty-eight Member States of the European Union in terms of economics, environmental, social and institutional activity. Information and data were retrieved from FADN database from the European Commission related to the year 2013, because is the last information available. The methodology includes the min-max approach based on the four components of sustainability, namely, economic, social, environmental and politics. We include the new institutional component in the sustainability because European agricultural is high subsidised and these subsidies have impacts on European agricultural sustainability. All the referred components of sustainability were based on various indicators in each component based on the literature. The min-max approach was employed to normalise the selected indicators expressed in variety dimensions for their need to be put on a common basis. Multivariate methods, namely, Component Principal Analysis was used to estimate weights for the selected indicators to construct sub-indices and then the sub-indices were aggregated into the farm relative sustainability index but adjusted to the present goals. Subsequently, cluster analysis was used cluster analysis was used to form homogeneous groups of European countries according to the agricultural sustainability indices. The results confirm three groups of European countries, namely, the North and Central countries; the Eastern European countries and the Mediterranean countries. The results confirm that European agriculture firms and respective countries had a medium sustainability. The main conclusion highlines confirms the importance of the sustainability as a tool to better adjust agricultural policies among the European Member States and the need to consider the social, environmental, institutional and competitiveness of the agricultural sector in each cluster of countries and respective agricultural firms.
- The sustainability in european agricultural firmsPublication . Dos Santos, Maria José Palma Lampreia; Mota, Manuel Gonçalves daEuropean agriculture plays an important role in European and world food security through the agricultural production, supply and international trade. The main aim of this paper was analyses the agricultural sustainability of the twenty-nine Member States of the European Union in terms of economics, environmental, social and political activity. Information and data comes from FADN database from the European Commission. The methodology includes univariate methods and multivariate methods, namely, Component Principal Analysis and Cluster analysis. The results confirm three groups of European countries, namely, the North and Central countries; the New Member States and the Mediterranean counties. The results also confirm that European agriculture firms and respective countries had a medium sustainability. The main conclusion highlines confirms the importance of the sustainability as a tool to better adjust agricultural policies among the European Member States.
- Sustainable and smart cities in Africa: A reviewPublication . Dos Santos, Maria José Palma Lampreia; Mota, Manuel Gonçalves daThis paper addresses the main challenges to be overcome so that cities in the future can be sustainable and also smart cities in the African Continent. The main goal of the paper is to analyse the main constraints to urban development in the African Continent in order for these cities to became smart cities in the future. The methodology was based on a literature revision of all the papers referred in Social Science Citation Index and SCOPUS Elsevier from Q2 to Q1. The results confirm the existence of huge challenges, problems and restrictions on social, economics, environmental and political issues in Africa and also confirm that smart cities will only be possible in Africa when the current problems of sustainable development (economic, social, environmental and political) are overcome. However, the paper allows us to understand why, this is the first paper in the literature to address the topic of smart cities in Africa. It should be noted that in this continent there are at least two of the world's largest cities in terms of inhabitants and the growth of population rate of the African continent is about 2.5%. This is a global problem to handle. The concern about the problems of sustainable development in this region and how to promote it towards sustainable cities concerns everyone and the next steps will affect all of the world’s sustainable development.
