Purpose: The purpose of this study is to examine the understanding of sustainability of the faculty members in higher education in Saudi Arabia. One of the main objectives is to explore how they implement sustainability in the courses offered in one of the major non-profit private universities in Riyadh. Findings: A survey was conducted among the faculty members to investigate their awareness on this topic. Survey results were compared between the different departments to understand how the faculty members can contribute to sustainable education if they increase their knowledge through training and workshops related to the topic. The comparative analysis allows us to define the guidelines to build a strong institution that presents itself as a leader and change-driver in the Gulf region. The survey was done among the limited number of faculty members in the benchmark university, searching for answers about sustainability using the top-down methodology. The survey fulfilled the original aim of developing an evidence base of faculty members existing expertise, experience and interest in sustainability. The survey is also an important step to embed sustainability into the benchmark university. It also provides an opportunity to reflect and put forward suggestions on what it means to have sustainability as a core value and strategic priority.

Motivation to study engineering in undergraduate study is of great importance to students. It encourages undergraduate students to enroll in an engineering program and continue their studies without dropping out. Male students enroll in engineering programs with large numbers compared to female students in many parts of the world. In Saudi Arabia, there were limited engineering programs for female students. In this research, the motivation to study engineering is studied and compared between male and female students in the College of Engineering at Prince Sultan University, the first private university in Saudi Arabia. The study was conducted through a detailed survey distributed to 41 male engineering management students and 45 female architectural engineering students. These students’ performance and experience were considered and compared considering their gender to evaluate their persistence toward engineering study. According to the results obtained, the highest degree of the parents had a considerable effect on the selection of engineering major for male and female students. Most surveyed male and female students select an engineering major because of its positive impact on the community and its role in improving the way of life. Male students may differ in that they considered engineering in order to start their own business after graduation with a higher percentage compared to female students. There was a very limited role of the school in selecting engineering majors according to the surveyed male and female students. This role should be enhanced and utilized to encourage more female students to consider engineering majors in their college study.

The pursuit of sustainability has necessitated more renewable resources in construction materials. Plant-based natural fibres, which can be found globally, are abundant, low-cost and renewable. Moreover, plant-based fibres can improve the mechanical properties of construction materials as a low-cost, environmentally friendly renewable option. Accordingly, a thorough understanding of the characteristics and drawbacks of plant fibres, focussing on their use in cement-based composites, is needed to explore their potential in structural applications. Therefore, this study developed a conceptual framework to assess the factors affecting plant-based natural fibres and cement composites. The paper further demonstrates the application of the proposed framework to predict associated challenges and offers appropriate solutions. Finally, date palm fibres are suggested for future applications of the proposed conceptual framework.
