More than 59 million people reside in the six member countries of the Gulf Cooperation Council (GCC) (the United Arab Emirates, Bahrain, Kuwait, Oman, Qatar, and Saudi Arabia). The rate of urbanization is more than 80% in each of these countries. To better understand the trends and knowledge structures and to aid policy design and implementation, more research is needed on the topic of urbanization in GCC countries. In order to address this knowledge gap, bibliometric analysis and scientific mapping procedures utilizing VOSviewer were employed. A total of 415 academic papers covering four decades, from 1980 to 2021, were collected from the Web of Science database and split into three time periods: 1980–2017, 2018–2019, and 2020–2021. The findings indicate that the topics related to sustainable development, environmental regulations, renewable energy, and smart cities have received the most attention. In addition, land use planning, urban growth, and energy consumption have been dominant themes over different periods. Several intertwined factors have contributed to the evolution of research over these periods. These include the widespread diffusion of the sustainability agenda, the rise of advanced ICT, and the escalating rate of urbanization. It can also be explained by the fact that the world has been grappling with numerous environmental challenges, increasingly requiring innovative solutions for sustainability. The findings of this study can be used to develop better strategies for sustainable urban development in the region.

Background: Over the past few years, five domains of importance about the current state of bioethics in Saudi Arabia have shaped the perspective of most research: doctor-patient relationship, informed consent, do-not-resuscitate, organ donation, and transplantation, medical students’ knowledge and attitudes about medical ethics curriculum. This systematic review aimed to systematically identify, compile, describe and discuss ethical arguments and concepts in the best-studied domains of bioethics in Saudi Arabia and to present cultural, social, educational, and humane perspectives.Methods: Six databases were searched using Boolean operators (PubMed, Embase, Web of Science, Scopus, CINAHL, Google Scholar) from December 2020–June 2021. The search and report process followed the statement and flowchart of preferred reporting items for systematic reviews and meta-analyses (PRISMA).Resutls: The search resulted in 1651 articles, of which 82 studies were selected for a final review and assessment. There is a gradual increase in research, whereby a substantial increase was observed from 2017. Most of the published articles focused on ‘Organ Donation & Transplantation’ with 33 articles, followed by ‘Doctor-Patient Relations’ with 18 publications. Most of the published articles were from Central Province (33), followed by Western Province (16). The authorship pattern showed a collaborative approach among researchers. The thematic analysis of keywords analysis showed that ‘Saudi Arabia,’ ‘attitude PHC,’ ‘organ donation,’ ‘knowledge and education,’ and ‘donation’ have been used the most commonly.Conclusion: This systematic quantitative synthesis is expected to guide researchers, stakeholders, and policymakers about the strengths and gaps in knowledge and attitudes regarding medical ethics in Saudi Arabia, both among the general public and health professionals.
