Since the early days of the COVID-19 crisis the scientific community has constantly been striving to shed light on various issues such as the mechanisms driving the spread of the virus, its environmental and socio-economic impacts, and necessary recovery and adaptation plans and policies. Given the high concentration of population and economic activities in cities, they are often hotspots of COVID-19 infections. Accordingly, many researchers are struggling to explore the dynamics of the pandemic in urban areas to understand impacts of COVID-19 on cities. In this study we seek to provide an overview of COVID-19 research related to cities by reviewing literature published during the first eight months after the first confirmed cases were reported in Wuhan, China. The main aims are to understand impacts of the pandemic on cities and to highlight major lessons that can be learned for post-COVID urban planning and design. Results show that, in terms of thematic focus, early research on the impacts of COVID-19 on cities is mainly related to four major themes, namely, (1) environmental quality, (2) socio-economic impacts, (3) management and governance, and (4) transportation and urban design. While this indicates a diverse research agenda, the first theme that covers issues related to air quality, meteorological parameters, and water quality is dominant, and the others are still relatively underexplored. Improvements in air and water quality in cities during lockdown periods highlight the significant environmental impacts of anthropogenic activities and provide a wake-up call to adopt environmentally friendly development pathways. The paper also provides other recommendations related to the socio-economic factors, urban management and governance, and transportation and urban design that can be used for post-COVID urban planning and design. Overall, existing knowledge shows that the COVID-19 crisis entails an excellent opportunity for planners and policy makers to take transformative actions towards creating cities that are more just, resilient, and sustainable.

Since its emergence in late 2019, the COVID-19 pandemic has swept through many cities around the world, claiming millions of lives and causing major socio-economic impacts. The pandemic occurred at an important historical juncture when smart solutions and technologies have become ubiquitous in many cities. Against this background, in this review, we examine how smart city solutions and technologies have contributed to resilience by enhancing planning, absorption, recovery, and adaptation abilities. For this purpose, we reviewed 147 studies that have discussed issues related to the use of smart solutions and technologies during the pandemic. The results were synthesized under four themes, namely, planning and preparation, absorption, recovery, and adaptation. This review shows that investment in smart city initiatives can enhance the planning and preparation ability. In addition, the adoption of smart solutions and technologies can, among other things, enhance the capacity of cities to predict pandemic patterns, facilitate an integrated and timely response, minimize or postpone transmission of the virus, provide support to overstretched sectors, minimize supply chain disruption, ensure continuity of basic services, and offer solutions for optimizing city operations. These are promising results that demonstrate the utility of smart solutions for enhancing resilience. However, it should be noted that realizing this potential hinges on careful attention to important issues and challenges related to privacy and security, access to open-source data, technological affordance, legal barriers, technological feasibility, and citizen engagement. Despite this, this review shows that further development of smart city initiatives can provide unprecedented opportunities for enhancing resilience to the pandemic and similar future events.

Global connectivity facilitated tourism and redefined economic landscapes, highlight an interest in better understanding tourism retention factors. Today, in view of the global COVID-19 pandemic, this is made even more important as the world prepares to lift lockdown restrictions and to re-engage in cross border circulation; reiterating needs to understand tourism satisfaction and revisit intentions. This study thus sheds light on the predictors of tourists’ intention to the explorative and exploitative use of Smart Tourism Technologies (STTs) and memorable experiences in tourism destinations via an integrated model and a self-administered questionnaire—distributed among domestic tourists visiting Tehran—employing the Theory of Planned Behavior (TPB). The results indicated that tourists’ attitudes, subjective norms, and perceived behavioral control toward STTs had significant positive impacts on their explorative and exploitative intentions. Furthermore, tourists’ explorative/exploitative intention and perceived behavioral control exercised significant, positive effects on their memorable experiences. Finally, the results demonstrate that tourists’ memorable experiences significantly influence their satisfaction and intention to revisit smart destinations. This study expands existing literature by exploring a new model for enhancing memorable experiences and revisit intention using STTs, and presents findings applicable to the city of Tehran, while adopting a model which can be replicated in other geographies looking at better understanding its tourism landscape. Finally, the results in this study can be helpful for both researchers and policy makers in their quest to rejuvenate local post-pandemic economies via tourism measures.
