Most developing economies are plagued by a low supply of skilled human capital, which is a known driver of economic growth and development. The introduction of the fourth industrial revolution (4IR) concept to the construction industry referred to as Construction 4.0 has introduced new technologies that require an increase in knowledge and skills requirement for workers. This comes with a host of challenges for developing countries. To this end, the current study focuses on Nigeria, which is the largest economy in Africa and a fast developing country. The study therefore seeks to explore the knowledge and skills gap among professionals within the Nigerian construction industry. This was achieved via a structured survey research design to elicit information from professionals in the construction industry. A convenience sampling technique was used to select 136 respondents. Data collected from the questionnaire were analysed using mean score, Pearson chi‐square and t test of SPSS V23. The findings revealed a moderate knowledge level of Construction 4.0 technologies and a low level of training among professionals. Also, the result shows a high skills gap in human machine communication, data analytics and cyber security. The study recommends the promotion of human capital development to enhance the implementation of Construction 4.0. This can be achieved via a review and redesign of existing curricula in educational institutions and commitment on the part of management and professional bodies to training and re‐skilling of the workforce.

The aim of this study is to examine the opportunities and threats of construction 4.0 on the workforce. This study adopts a qualitative and quantitative survey research design. A purposive sampling technique was used to select forty (40) respondents which comprises of project managers and supervisors of ongoing projects selected across four states in Southwest Nigeria.  Frequencies, percentage, mean, Bivariate Pearson and Kendall’s tau b correlation of SPSS V23 were used in analysing the data collected. The result shows that there was a high level of implementation of Prefabrication and BIM. The study further revealed opportunities such as increased collaboration, creativity, workers’ efficiency and a major threat which is retrenchment of workers. This threat is a resultant effect of construction 4.0 to the workforce. Also, the study reveals that manual jobs face higher threats under construction 4.0 compared to professional jobs. The study recommends the need for more sensitization of the work force for construction 4.0, re-skilling of the workforce and development of government policies to protect the work force against the major threat of construction 4.0 which is retrenchment.

In contributing to reducing the adverse effects of non-renewable energy sources, this paper researched how human capital can enhance the penetration level of renewable energy, which is highly abundant in Nigeria, Sub-Saharan Africa. This paper, using qualitative research methodology through Bibliometric analysis, reviewed three hundred and three (303) papers published between the year 2000 and March 2022. The bibliometric study covered publications per author, publications per country, research focus based on co-occurrence keywords, and research thread. The findings revealed that publications on how human capital can aid renewable energy penetration have been slow and in an infant stage in the past two decades. It also shows that there have been eighteen (18) papers on the subject papers in the last twenty years, showing the low level of human capital development in the energy sector. The intellectual patterns via the co-occurrence of keywords shows five (5) clusters, which are economics of renewable energy sources, human capital factors in environmental management, economic factors in energy supply and demand, sustainable energy factors, and human capital development and economy. These cluster areas revealed how human capital could be developed to increase the penetration level of the abundant renewable energy in the world. Thus, this paper recommends intensive efforts in optimizing human capital through inter-organizational collaboration on renewable energy technologies and periodic training.

The main purpose of this study is to assess the role of tertiary institutions in impacting innovation competence among graduating students in the engineering discipline. To achieve this aim, two research questions were investigated: First, we examine if the graduating students possess some key innovative competence qualities innovative competence which include qualities such as creativity, leadership, self-efficacy, energy and risk propensity. Secondly, we investigate the key elements of tertiary institutions that impact innovative competence among the graduating students. A structured questionnaire was administered to graduating engineering students at the Federal University of Technology Akure, Nigeria and University of Johannesburg, South Africa during the 2019/2020 academic session and their responses were compared. Results indicate that students generally had a high assessment of their innovation competence and attributed some of this competence to their institutions learning environment.
