    Abstract: Introduction: Vaccine inequality inflames the COVID-19 pandemic. Ensuring equitable immunization, vaccine empathy is needed to boost vaccine donations among capable countries. However, damaging narratives built around vaccine donations such as “vaccine diplomacy” could undermine nations’ willingness to donate their vaccines, which, in turn, further exacerbate global vaccine inequality. However, while discussions on vaccine diplomacy are on the rise, there is limited research related to vaccine diplomacy, especially in terms of its characteristics and effects on vaccine distribution vis-à-vis vaccine empathy. Thus, to bridge the research gap, this study aims to examine the defining attributes of vaccine diplomacy and its potential effects on COVID-19 immunization, particularly in light of vaccine empathy. Methods: A narrative review was conducted to shed light on vaccine diplomacy’s defining attributes and effects in the context of COVID-19 vaccine distribution and dissemination. Databases such as PubMed and Medline were utilized for literature search. Additionally, to ensure up-to-date insights are included in the review, validated reports and reverse tracing of eligible articles’ reference lists in Google Scholar have also been conducted to locate relevant records. Results: Vaccine empathy is an individual or a nation’s capability to sympathize with other individuals or nations’ vaccine wants and needs, whereas vaccine diplomacy is a nation’s vaccine efforts that aim to build mutually beneficial relationships with other nations ultimately. Our findings show that while both vaccine empathy and vaccine diplomacy have their strengths and weaknesses, they all have great potential to improve vaccine equality, particularly amid fast-developing and ever-evolving global health crises such as COVID-19. Furthermore, analyses show that, compared to vaccine empathy, vaccine diplomacy might be a more sustainable solution to improve vaccine donations mainly because of its deeper and stronger roots in multilateral collaboration and cooperation. Conclusion: Similar to penicillin, automated external defibrillators, or safety belts amid a roaring global health disaster, COVID-19 vaccines are, essentially, life-saving consumer health products that should be available to those who need them. Though man-made and complicated, vaccine inequality is nonetheless a solvable issue—gaps in vaccine distribution and dissemination can be effectively addressed by timely vaccine donations. Overall, our study underscores the instrumental and indispensable role of vaccine diplomacy in addressing the vaccine inequality issue amid the COVID-19 pandemic and its potentials for making even greater contributions in forging global solidarity amid international health emergencies. Future research could investigate approaches that could further inspire and improve vaccine donations among capable nations at a global scale to advance vaccine equity further.

    Abstract: Decades of reckless deforestation have caused serious soil erosion and land desertification issues in the Loess Plateau (LP). “Grain for Green” Program (GFGP), one of the world’s largest ecological restoration projects, is crucial to improve the ecological environment. Previous studies have demonstrated that GFGP lowers soil erosion in the LP. However, there are trade-offs and synergies between ecological services. Does strengthening soil conservation prevent enhancing other ecosystem services? Consequently, can the GFGP improve many ecological services simultaneously? This study compares changes in NDVI prior to and following the implementation of the GFGP in LP to the enhancement of ecosystem services. During the research period, the LP’s overall vegetation cover rose significantly, particularly in the GFGP’s major counties. Significant improvements were made to ecosystem services such as carbon sequestration, soil conservation, and habitat quality. The GFGP enhanced the synergistic linkages between ecological services. The implementation of the GFGP decreased water yield, suggesting trade-offs with other ecosystem services. Additionally, we investigate regional trade-offs/synergies between ecosystem services and their influencing factors, which were influenced by topographic and climatic variables. To maximize the benefits of ecological restoration efforts, we need a deeper understanding of the relationships between ecosystem services and the mechanisms that drive them. Thus, policymakers can scientifically exert control over local influences on ecosystem services, either by boosting the provision of specific services or by limiting specific influences in order to maintain ecosystem stability.

    Abstract: Information about urban land use is important for urban planning and sustainable development. The emergence of geospatial big data (GBD), increased the availability of remotely sensed (RS) data and the development of new methods for data integration to provide new opportunities for mapping types of urban land use. However, the modes of RS and GBD integration are diverse due to the differences in data, study areas, classifiers, etc. In this context, this study aims to summarize the main methods of data integration and evaluate them via a case study of urban land use mapping in Hangzhou, China. We first categorized the RS and GBD integration methods into decision-level integration (DI) and feature-level integration (FI) and analyzed their main differences by reviewing the existing literature. The two methods were then applied for mapping urban land use types in Hangzhou city, based on urban parcels derived from the OpenStreetMap (OSM) road network, 10 m Sentinel-2A images, and points of interest (POI). The corresponding classification results were validated quantitatively and qualitatively using the same testing dataset. Finally, we illustrated the advantages and disadvantages of both approaches via bibliographic evidence and quantitative analysis. The results showed that: (1) The visual comparison indicates a generally better performance of DI-based classification than FI-based classification; (2) DI-based urban land use mapping is easy to implement, while FI-based land use mapping enables the mixture of features; (3) DI-based and FI-based methods can be used together to improve urban land use mapping, as they have different performances when classifying different types of land use. This study provides an improved understanding of urban land use mapping in terms of the RS and GBD integration strategy.

    Abstract: China’s new-type urbanisation, as a national strategy, is one of the reasons why the leap in development has been made in the last decade. Existing studies mainly focus on the status and outcomes of china’s new-type urbanisation while stressing not enough the overlooked aspects of new-type urbanisation policies that are currently in use. This paper aims at exploring the highlighted and overlooked aspects of policies of three key elements in China’s new-type urbanisation: population, land, and industry and their implementations. The complicated process and contradictions between formulation and implementation of the policies are extracted by analysing set goals and implemented situations of relative indicators from the three elements. The policies drove the population from separation to unity between household registered and actual residences, land from human land allometry to balance, and industry from traditional industrialisation to emerging service. Although these policies had significant achievements in the transitions of formulation, they still needed to be further implemented. Furthermore, this paper discusses corresponding reasons and potential directions to better the adoption of these policies for greater inclusion and systematic efficiency. The findings could not only highlight directions that improve existing policies of China’s new-type urbanisation but also provide guidance for inclusive and sustainable urbanisation practices in China as well as other cities in similar situations all over the world.

    Abstract: Nature-based solutions (NBS) are an innovative concept that mimics the processes of natural ecosystems, popularized principally in the European Union. With a substantial body of literature amassed since the term’s inception in 2015, there is a need to systematically review existing literature to identify overarching gaps and trends, according to disciplinary focus, geographic scope, and key themes, and direct future research inquiry and policy recommendations. This review consists of bibliometric analysis and thematic analysis for NBS studies in urbanism. NBS studies were found to relate strongly with other concepts of ‘Ecosystem Services’, ‘Green Infrastructure’, ‘Climate Change’, and ‘Risk management and Resilience’, which align with four major thematic goals set by the European Commission. Within NBS scholarship, various sub-themes have emerged, namely, ‘Greening’, ‘Urban Development’, ‘Water’, ‘Wellbeing’, and ‘Governance’. Furthermore, we illustrate that the amount and thematic focus of NBS research have been unevenly distributed worldwide. Analysis of emerging trends shows a recent increase in topics, such as adaptive governance of NBS, and the incorporation of social justice in sustainability transitions. Based on an assessment of extant NBS literature, we offer some recommendations for the future direction of the research fields.

    Abstract: Traffic accidents have become severe risks as they are one of the causes of enormous deaths worldwide. Reducing the number of incidents is critical to saving lives and achieving sustainable cities and communities. Machine learning and data analysis techniques interpret the reasons for car accidents and propose solutions to minimize them. However, this needs to take the benefits of big data solutions as the size and velocity of traffic accident data are increasingly large and rapid. This paper explores road car accident data patterns and proposes a predictive model by investigating meaningful data features, such as accident severity, the number of casualties, and the number of vehicles. Therefore, a pre-processing model is designed to convert raw data using missing and meaningless feature removal, data attribute generalization, and outlier removal using interquartile. Four classification methods, including decision trees, random forest, multinomial logistic regression, and naïve Bayes, are used and evaluated to study the performance of road accident prediction. The results address acceptable levels of accuracy for car accident prediction except for naïve Bayes. The findings are discussed through a data-driven approach to understand the factors influencing road car accidents and highlight the key ones to propose accident prevention solutions. Finally, some strategies are provided to achieve healthy and community-friendly cities.

    Abstract: Urban regeneration has become one of the most effective ways to develop urban areas that have declined. Compared with other types of urban regeneration, community micro-regeneration is characterised by scattered stakeholders. Existing studies on public participation in community micro-regeneration mainly focus on revealing the interaction between different stakeholders with less attention to the main users’ social profiles in their participation process. This paper explores residents’ social profiles influencing their participation in community micro-regeneration projects in China. An evaluation framework for residents’ participation in community micro-regeneration projects is designed through literature research, the Delphi technique, and an analytic hierarchy process (AHP) based on the case study of Yongtai community, Guangzhou. Relative residents’ social profiles with the data from the questionnaire and literature research are further verified by stepwise linear regression. The results show that residents’ participation is still in the stage of tokenism with high-level passive information receipt but low-level enthusiasm for interactive activities. The older (i.e., 65-years of age and above) and middle-income groups (i.e., between 3000 and 14,999 CNY/Month) are positively associated with their participation in the Yongtai community micro-regeneration project. These findings can provide references for managers to distribute social resources.

    Abstract: This paper introduces the new concept of “eco-fusion” through an exploratory case study project. It suggests the importance of multi-scalar practice in the broader field of eco-urbanism. This study introduces eco-fusion as a multiplexed paradigm, which is then discussed in two different development models. This paper first highlights the position of “eco” in urbanism by providing a brief account of key terms and how they relate to one another. It then points out the associations between eco-fusion and sustainable urban development. Through an exploratory case study example in China, the practical factors of eco-development are assessed. The study aims to provide a set of intermediate development stages while maintaining each spatial level’s interface in their own defined and distinguished contexts. The key objective is to consider integrating the natural and built environments, which is considered the best practice of eco-development in urbanism. This study’s findings highlight integrated methods in eco-urbanism and suggest new directions for eco-planning/eco-design strategies.

    Abstract: The current global food system is under threat due to significant global changes such as rapid urbanization, climate change, COVID-19 outbreak, etc. The importance of food system sustainability as a key element of sustainable cities has been gradually recognized in recent years; however, the tools for estimating food system sustainability in cities (i.e., urban food system sustainability) holistically are still scarce. Thus, this study represents a comprehensive investigation into food system studies and their impacts on achieving a sustainable community or city. This study is a subset of larger studies that aim to develop an urban food system framework, which utilizes modern approaches in framework development such as sustainability food indicators and a participatory approach. However, to achieve this, trends, gaps, and challenges of the current approach to food system studies need to be reviewed and discussed. A systematic analysis utilizing the protocol of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach was conducted, and network analysis of publications was performed via VOS viewer. The results suggest applying circular principles and merging smartness and resilience thinking in developing strategies for food system sustainability. This study finds that key drivers to mitigate food crisis among countries vary. Furthermore, a context-specific framework with a more comprehensive definition of urban food systems covering the institutional processes, and food governance are also needed to achieve urban food system sustainability.

    Abstract: This research studies the data on air quality and construction activities from 29 January 2020 to 30 April 2020. The analysis focuses on three sample districts of Hangzhou’s Xiacheng, Gongshu, and Xiaoshan districts. The samples, respectively, represent low-level, mid-level, and high-level districts in the scale of construction projects. The correlative relationships are investigated, respectively, in the periods of ‘pandemic lockdown (29 January 2020–20 February 2020)’ and ‘after pandemic lockdown (21 February 2020–30 April 2020)’. The correlative equations are obtained. Based on the guideline values of air parameters provided by the Chinese criteria and standards, the recommended maximum scales of construction projects are defined. The numbers of construction sites are 16, 118, and 311 for the Xiacheng, Gongshu, and Xiaoshan districts during the imposed lockdown period, respectively, and 19, 88, 234, respectively, after the lockdown period. Because the construction site is only one influential factor on the air quality, and the database is not large enough, there are some limitations in the mathematical model and the management plan. Possible problem solving techniques and future studies are introduced at the end of the research study.
