This paper aims to provide an overview of the application of blockchain to agri-food supply chains, including key issues and trends. It examines the state of the art and conceptual structure of the field and proposes an agenda to guide future research.

This article performs a bibliometric analysis using VOSviewer software on a sample of 205 articles from the WoS database to identify research trend topics.

The number of publications in this area has increased since 2020, which shows a growing research interest. The research hotspots are related to the integration of blockchain technology in the agri-food supply chain for traceability, coordination between all actors involved, transparency of operations and improvement of food safety. Furthermore, this is linked to sustainability and the achievement of the sustainable development gtoals (SDGs), while addressing key challenges in the implementation of blockchain-based technologies in the agri-food supply chain.

The application of blockchain in the agri-food supply chain may consider four key aspects. Firstly, the implementation of blockchain can improve the traceability of food products. Secondly, this technology supports sustainability issues and could avoid disruptions in the agri-food supply chain. Third, blockchain improves food quality and safety control throughout the supply chain. Fourthly, the findings show that regulation is needed to improve trust between stakeholders.

The paper provides a comprehensive overview of the blockchain phenomenon in the agri-food supply chain by optimising the search criteria. Moreover, it serves to bridge to future research by identifying gaps in the field.

The aim of this study is to understand the acculturation experiences of international students in order to maximize their academic and social experiences which, in turn, can facilitate the development of sustainable educational tourism in the host country.

Using a qualitative methodology and semi-structured interview techniques, 40 international postgraduate tourism students from the Global South were interviewed.

The findings in this study demonstrated that the main problems faced by these students are inadequate funds and language difficulties.

This study highlighted the fact that although the number of international students is growing all over the world, for most of the students from poorer parts of the world, being an international student is fraught with difficulties. It also demonstrated that although acculturation stress is a serious concern, lack of adequate funding assumes greater importance for students from a poor background.
