This study aims to help scholars comprehend the major research themes on sustainable development goals (SDGs) in higher education which researchers from various fields have explored and to propose several potential future research directions of the least researched SDG in higher education to support scholars in making up the gap in the field.

The authors adopted a bibliometric analysis method to review the extant literature from the Web of Science on SDGs in higher education from 2015 to 2023 and took a closer examination of the most researched SDGs discussed by scholars. This study specifically concentrated on studies that explicitly mentioned the term “Sustainable Development Goal” (or “SDG”) and applied VOSviewer to cluster common keywords of the most researched SDGs and explored related themes. Also, this study provided several potential future research directions of least researched SDG in higher education.

SDGs 3 and 4 were the most researched, and SDG 15 was the least researched. The three major themes of SDG 3 were Adult Issues of Sustainability, South Africa Issues of Sustainability, and Relationship between SDG 3 and SDG 4. The three major themes of SDG 4 were the Role of Universities in Sustainability, Sustainability during Covid-19, and Challenges of Implementation.

This study provided several potential future research directions of the least researched SDG in higher education to support scholars to make up the gap in the field. Also, this study pointed out some pedagogical strategies and competencies needed to aid higher education institutions in achieving the 17 SDGs.

The purpose of this paper is to analyse the current state of research on the integration of blockchain and building information modelling (BIM) in the Architecture, Engineering, Construction and Operations (AECO) industry as a means of identifying gaps between the existing paradigm and practical applications for determining future research directions and improving the industry. The study aims to provide clear guidance on areas that need attention for further research and funding and to draw academic attention to factors beyond the technical dimension.

A mixed-method systematic review is used, considering multiple literature types and using a sociotechnical perspective-based framework that covers three dimensions (technic, process and context) and three research elements (why, what and how). Data are retrieved and analysed from the Web of Science and Scopus databases for the 2017–2023 period.

While blockchain has the potential to address security, traceability and transparency and complement the system by integrating supporting applications, significant gaps still exist between these potentials and widespread industry adoption. Current limitations and further research needs are identified, including designing fully integrated prototypes, empirical research to identify operational processes, testing and analysing operational-level models or applications and developing and applying a technology acceptance model for the integration paradigm. Previous research lacks contextual settings, real-world tests or empirical investigations and is primarily conceptual.

This paper provides a comprehensive, critical systematic review of the integration of blockchain with BIM in the construction industry, using a sociotechnical perspective-based framework which can be applied in future reviews. The study provides insight into the current state and future opportunities for policymakers and practitioners in the AECO industry to prepare for the transition in this disruptive paradigm. It also provides a phased plan along with a clear direction for the transition to more advanced applications.
