This paper examines the competitiveness of international orange trade over the period 1993-2018 based on global data. The paper uses the methodology of comparative advantages to analyse fresh orange and orange juice data. Results suggest that most competitive countries are focusing on processed orange trade. Although Brazil is the world's largest orange-producing country, it is not among the top 10 countries in the global orange fruit market, representing that it mainly focuses on processing. Results also suggest that there is no high concentration in the export market for fresh oranges, however, Spain's share is growing steadily, as well as South Africa and Egypt can be mentioned as emerging nations. With further analysis of the international orange trade, Egypt's comparative advantage over fresh oranges increased the most and had the highest results in recent periods followed by South Africa, Greece and Spain. By examining global orange juice trade, it is not surprising that Brazil had the largest comparative advantage, although its value is constantly declining. With a dynamic analysis of comparative advantages, a large decrease can be observed in the chance of survival of the advantages. [ABSTRACT FROM AUTHOR]

Agricultural techniques and orchard management play an important role in food production sustainability and there is an increasing number of research papers that focus on food cradle-to-gate life cycle assessment. In addition, there is also an emerging body of research on short food supply chains and on whether or not proximity can be a proxy for sustainability in the agri-food system. The objective of this analysis is to consider the most relevant social and environmental impacts of the Environmental Footprint and Social Life Cycle Assessment in the citrus fruit sector and identify crucial hotspots. We will explore the relevance of the length of citrus fruit supply chains on maps of social and environmental impacts in order to reach more wiser sustainability-based decisions. The results obtained show mixed conclusions regarding the relevance and implications of choosing short food supply chains to achieve more sustainable food systems. [ABSTRACT FROM AUTHOR]
