• A novel biomass-solar based multigeneration system is developed. • The energy, exergy, environment and economic assessments are conducted for the system study. • The thermal energy storage system is designed to store excess heat during the day. • The overall system's energy and exergy efficiencies are 37.68 % and 71.25 %, respectively. An integrated energy system is designed to produce various useful products, such as hydrogen, electricity, heat and cooling. This integrated plant utilizes various subsystems; solar power system, biomass energy system, steam Rankine cycle (SRC), Brayton cycle (BC), organic Rankine cycle (ORC), double-effect absorption system (DEAS), reverse osmosis system, and sonohydrogen production unit. The specific energetic, exergetic, economic and environmental impact assessment studies are carried out to evaluate the system's performance and sustainability. The engineering equation solver (EES) is used for these studies. The energy efficiencies for the BC, ORC and SRC are recorded as 29.69 %, 10.49 %, and 30 %, respectively. In regard to exergy efficiency, the BC, ORC and SRC achieve the following: 46.74 %, 62.73 %, and 53.43 %, respectively. Furthermore, the DEAS attains energetic and exergetic COPs of 1.67 and 0.65, respectively. Additionally, the overall system's energy and exergy efficiencies are found to be 37.68 % and 71.25 %, respectively. The results from the thermal energy storage system indicate that the heat production begins at 7:00 a.m., and the charging of the storage unit commences two hours after and continues until 5:00 p.m., in coinciding with the availability of sunlight. The economic analysis demonstrates that with an initial investment of $53.80 million, the integrated multigeneration system achieves a net present value ranging from $6.87 million to $173.4 million across different hydrogen selling prices, from $7000 to $13,000 per ton up to 2054.

• A gravity model was used to measure accessibility. • Competition over public chargers was considered in the accessibility measure. • Public chargers' distribution is examined through various equity perspectives. • The same distribution can be presented as either equitable or inequitable. • The current distribution fits with utilitarian and capabilities equity theories. This study assessed the availability and accessibility of public electric vehicle (EV) charging stations at the census tract level in King County, Washington, USA. A gravity model was used to measure the accessibility of stations in each tract while considering the competition among tracts for charging infrastructure. Unlike prior studies, we evaluate current distribution from various equity viewpoints, clearly defining these perspectives and investigating their implications for charging distribution. The findings revealed significantly higher accessibility of public stations in areas with a lower share of single-family homes, a higher share of commercial areas, and proximity to major roadways, irrespective of population and EV adoption rates. Moreover, we found that the current distribution is consistent with utilitarian and capabilities-based theories of equity. Spatial tools such as Moran's I and spatial regression were used to analyze the spatial disparity of the proposed accessibility measure, showing the existence of a highly clustered spatial distribution. This study offers valuable insights into integrating equity considerations in assessing accessibility to transportation facilities, especially EV charging stations. Such an approach can facilitate the promotion of EV adoption across diverse groups, a critical factor in achieving sustainable city development goals by mitigating carbon emissions and enhancing mobility.

The paper aimed to investigate the fragmented governance in South African cities which creates dilemmas in planning and management of urbanisation. Urbanisation is unstoppable, irreversible and inevitable in both developing and developed countries. The inevitability of urbanisation, therefore, underscores the need for effective planning and management of this process to guide orderly sustainable urban development and the attainment of sustainable cities. However, the fragmentary governance and exclusive planning, which find their etymology from colonialism, continue to manifest in South African municipalities post-independence. South African cities were ill-prepared to cater for the increasing urban population, which resulted in unplanned settlements, traffic congestion, service delivery backlog and overconsumption of resources. This spatial planning has created cities where the low-income people bear the brunt of commuting every day to access the cities. The study is grounded in resilient theory, which provides urban planners with a methodological approach to ensure that cities are operational post perturbation. Fragmentary governance and exclusionary planning need to be relinquished as a matter of state policy and promote inclusive cities. The paper recommended that local municipalities must acquire capacitated and ethical employees to circumvent the misuse of municipal funds. [ABSTRACT FROM AUTHOR]

The Sustainable Development Goals set by the United Nations in the 2030 agenda point out the need to safeguard cultural heritage and the importance of convergence towards quality education. Through different museum projects (between 2010 and 2021), the DIDPATRI research group of the University of Barcelona has developed heritage museum models following sustainability parameters. The lines of work have been based on the use of previous museum cultures (integrating existing models) to respond to the needs of the present. The working hypotheses have raised the need to build a new social museography around the historical heritage, which can respond to the social demands of citizen education and sustainability. Museography should be oriented to formal and non-formal teaching-learning environments. Social museography must be based on the understanding of historical heritage in broad sectors of the public as well as on the participation of social agents, civil society, and the scientific community. Social museography must be based on the enhancement of heritage resources (tangible or intangible) in a way that is compatible with sustainable development options; it must be built with the support of protocols that consider production costs that are consistent with the economic and social resources available and with the reasonable use of complex technologies. This desire for research (on the paths of a new social museography) has been channeled through the development of research and transfer projects. The results obtained have generated empirical models that have contributed (methodologically) to the development of museographic options that respond to emerging demands in the environment of historical-archaeological heritage.

In recent years, Malaysia has faced environmental challenges caused by municipal solid waste, especially household waste, during the COVID-19 pandemic. Among all the household waste, plastic and paper are the most unmanaged waste that cause environmental issues. Several recycling associations in Malaysia have carried out their practices for better waste sustainability and management to curb the increasing amount of household waste. However, the effectiveness is still vague in achieving smart and effective household waste management. Therefore, this paper aims to investigate Malaysia's household waste management, mainly in three significant municipalities in Malaysia, namely Kuala Lumpur, Penang, and Melaka, in becoming a resilient and sustainable city by addressing two main research questions: (1) What are the key factors for ensuring the more successful moves for future household waste management in cities? and (2) How do each of the three municipalities of Malaysia cities address their waste issues based on the key factors from RQ1? This paper reviewed 13 waste management articles and explores the potential of the four factors of waste management from the perspective of technology and data, economy, social, and governance. The discussed factors and models contributed to an integrated future-proofing framework that focuses on smart waste tracking, a gamified awareness education, and strict policies to control waste management are the way forward for the future of smart cities household waste management.

Cities around the world are attempting to become smarter by using data and technology to improve internal operations, make better decisions, and increase the quality of life. This technology-intensive use frequently comes with large investments in the ICT infrastructure necessary for smart city initiatives, which may not be financially viable in the long term. Financial sustainability (FS) is a useful framework for assessing how governments meet their financial obligations, using different indicators of financial performance over time by controlling for contextual factors. This study examines 1723 municipal governments; only 89 of these explicitly conducted smart-city initiatives in Mexico over three time points (2014, 2016, and 2018). Panel data techniques were applied to compare the effects of the investments in ICT infrastructure across municipalities with or without smart-city initiatives on five indicators related to the financial condition within the FS framework (i.e., cash solvency, budget solvency, long-term solvency, service-level solvency for revenues and expenses). The results show an association between ICT infrastructure and some dimensions of FS. The main findings suggest the importance of adequate financial analysis for long-term capital and budgeting decisions, to create a more solid smart city financial strategy for the long term. Specific recommendations for city managers are also discussed. [ABSTRACT FROM AUTHOR]

Climate change is affecting cities worldwide. Accordingly, cities are required to find sustainable solutions to tackle climate change's effects, designing bottom-up policies to enhance their success. The involvement of stakeholders plays a central role in the definition of appropriate policies to tackle the challenges posed to cities by climate change. Nature-based solutions (NBS) are increasingly proposed to adapt to and mitigate the adverse effects of climate change. This study aims to assess the coherence of the policies emerging from stakeholders' perceptions of urban climate challenges and their preferred NBS to tackle them. Indeed, it considers whether departing from different urban climate challenges, stakeholders' choices present a coherent articulation between priority interventions, proposed solutions and expected benefits. Using a survey applied to two Portuguese cities and the chi-squared automatic interaction detector (CHAID) algorithm, we analyse the answers provided by stakeholders. The stakeholders' perceptions and preferences were not significantly influenced by their hierarchical position in their institutions, their city's location and socioeconomic setting. Heatwaves and temperature rise together with drought and water scarcity are identified as future urban challenges in Portugal. Priority interventions, as well as preferred NBS and their expected benefits, are addressed. The results show that stakeholders may make decisions that form a coherent policy, in which acknowledgment of climate change's effects interconnects with related priority interventions, suitable NBS and their benefits. • Involvement of stakeholders by considering their perceptions and preferences. • Importance of a coherent policy in NBS development and implementation. • Interconnection between urban challenges, priorities, NBS and benefits from NBS. • Causal relationship between climate challenges and proposed NBS. • The stakeholders' perceptions and preferences were not influenced by their city's location and socioeconomic setting.

Indicator-based evaluation systems are critical for guiding and monitoring cities' sustainable development. Zhangjiakou city is the national renewable energy demonstration zone in China, and is gaining more attention (being the co-host city of the 2022 Winter Olympic Games). It needs to seize the opportunities for its long-term sustainable development. An indicator system was developed to monitor the city's sustainability. Local governance was integrated into an extended three-pillar evaluation model as the fourth dimension through the involvement of over 30 local government departments. Based on the interpretation of local demands, 118 assessment tools were reviewed and an international indicator inventory of 224 indicators was established. By analyzing the local relevance, 95 indicators were selected and categorized into eight modules (energy and carbon emission, resources and environment, harmony and well-being, economics and inclusion, key industries, innovation and smart, governance and efficiency, and internationalization). However, only 67 indicators were confirmed for value assignments after applicability assessment. Basic performance values (BPVs) were given as achievable goals during the 14th Five-Year Plan (FYP), and the excellent performance values (EPVs) were given towards carbon neutrality. All of the values were peer-reviewed and agreed by the local government while discrepancy still exists on carbon emission. [ABSTRACT FROM AUTHOR]

Problems related to air quality in large urban agglomerations (e.g., high concentration of pollutants, the urban heat island phenomenon) make it necessary to take comprehensive measures to improve air exchange in urban areas. The paper concerns the relationship between wind phenomena observable in cities and the geometrical features of building development. The knowledge on the subject is already well-founded and has been intensively developed. Regardless, it remains relatively poorly applied to urban planning. Based on the analysis of source literature, the classification of features and spatial elements of building development that are crucial for ventilation is conducted in the following paper. Five different cities are also analyzed regarding how the air exchange improvement policy should be pursued through conscious building development shaping. The cities selected for analysis include Warsaw and Cracow in Poland, a large agglomeration of New Dehli in India, the experimental Masdar City in the United Arab Emirates, and the newly designed Jätkäsaaridistrict of Helsinki. Based on the example of the above cities, the paper investigates the possibilities of combining spatial features of building development that are essential to aerodynamics, in order to create effective ventilation systems.

The concept of sustainable cities is based on a development paradigm that recognizes the rapid growth of the urban population and makes an important contribution to the formation of the urban plan. Sustainable urban development is a prerequisite for creating a sustainable city. A sustainable and smart city involves innovative solutions. This paper will define what a sustainable city is and it will show how certain innovative solutions were introduced in Copenhagen in order to achieve city sustainability. To that extent, an overview of innovations in the context of environmental protection is given.

This data article presents a tripartite dataset that formed the empirical basis for a comprehensive bibliometric analysis of the use of city labels denoting sustainable urbanism in the scientific literature (Schraven, 2021). The tripartite dataset was generated using the abstract and citation database Scopus (Elsevier). Dataset A lists 148 city labels denoting different approaches to urban planning and development. It was used to select 35 city labels that specifically address sustainable urbanism (‘sustainable city’, ‘smart city’, ‘compact city’ etc.). Dataset B references 11,337 journal and review articles spanning the period 1990–2019. All retrieved articles contain at least one of the 35 city labels in the title, abstract, and author keywords. This database was used to calculate the frequency of the selected city labels across time, and to analyze the co-occurrences of city labels. It was further used to calculate the future trajectory of scientific outputs using the Logistic Growth Model (LGM). Dataset C entails 22,820 author keywords extracted from across the 11,337 articles. This was used to analyze the co-occurrences of keywords with city labels. The data article describes the methods of data collection and curation, the analysis performed, and the potential for reusing the data for further research. The comprehensiveness of the bibliometric corpus – spanning three decades and 35 city labels – lends itself to further investigation of how sustainable urban development has evolved as a topic in the scientific literature since the 1990s. Furthermore, the robust methodology developed could be adapted to other scientific repositories and, indeed, other research problems and questions.

This article examines the need and opportunities to implement vertical green in Ljubljana as a case of a medium-sized European city with a relatively green feel. Sustainability-oriented urban development supports the introduction of nature-based solutions in principle; however, there is a lack of vertical green as well as actual legislative and administrative support. Therefore, several methods were applied in the present study to link this idea to execution, starting with semi-structured interviews and a workshop for selected city officials. Legislative and formal backgrounds for implementation were then assessed. An inventory of green façades and other structures (e.g., noise barriers and retaining walls) in Ljubljana was prepared, and a geographic information system-based decision support system was developed to identify the potential areas in the city where additional green space elements would be most favourable for humans, the environment, and climate indicators. The results reveal a gap between opportunities and the actual situation. The general opinion that there is never too much green space in urban areas is confirmed by direct information from the city administration and strategic documents. There are many potential sites for implementation; however, this is hindered by ownership, management, and economic issues. The study concludes with some suggestions for following the best practices in other central European capitals, such as Vienna and Berlin. [ABSTRACT FROM AUTHOR]

The United Nations' Sustainable Development Goals (SDGs) are regarded as the key policy agenda for national, regional, and local government to combat climate change impacts and promote sustainable development. For example, in Perth and Peel metropolitan area, the capital city of Western Australia, there has been a shift of policy setting from that of a sprawling city to a denser city, while maintaining and promoting its ecosystem services and achieving sustainable city goals. Residential verge gardens have been widely adopted in recent years by communities and local governments in the Perth metropolitan area. This study reviews the motivations and drivers for the uptake of verge gardens in metropolitan suburbs and identifies potential policy responses. The City of Bayswater local government area was surveyed for this research. The study considers a mixed-methods approach, including site auditing and a questionnaire survey for local residents who have transformed their verges. A total of 534 verge gardens were audited on residential lots, and 166 valid questionnaire responses were received from residents. The site-audit of the verge gardens in Bayswater found that native vegetation is the dominant verge garden of choice, followed by the ornamental garden, with food production (plants/vegetables) seeming to be the least popular option. Regarding the motivations and drivers, the study has found that social (e.g., aesthetics, flowers, social interactions, and social mimicry), environmental (e.g., attracting wildlife and birds and environmental practice waterwise garden), and personal (easy maintenance) drivers are the primary motivators for residents to adopt verge gardens. Whilst the on-ground surveys were prior to COVID-19, the article includes how this topic could relate to pandemic-resilient urban spaces. As local governments look towards supporting the sustainable outcome goals, the observations of this study will be helpful for developing local government policy and community programs in the promotion and uptake of verge gardens in Australian cities.

Urban spaces in Latin America and the Caribbean have become strategic centers of experimentation of city models that allow for the reproduction of capital. This paper reflects on the link between neoliberal urbanism and urban restructuring, focusing on the role the Inter-American Development Bank (IDB) plays in the planning of intermediate cities in the region. For this purpose, we take as case studies the programs "Initiative of Emerging and Sustainable Cities" (ICES) and "Development of Metropolitan Areas of the Interior" (DAMI), both implemented in the last decade (2011-2021) in the Metropolitan Area of Mendoza (AMM), Argentina. We analyze the central role played by the UNICIPIO-IDB alliance in metropolitan management, focusing on the axes of citizen security and interventions of urban transformation in central areas. The work carried out shows the key role played by the IDB in progressively determining the urban agenda and implementing neoliberal urban models, through its technical advice and the financing of certain urban programs, under the discourse of sustainability. A qualitative methodological design was carried out, focusing on case analysis. We used secondary sources, including official documents prepared by the IDB, the provincial government, UNICIPIO and the Municipality of Mendoza, as well as journalistic articles and sectorial magazines.

The growth of cities often disordered brings several mobility challenges, both in guaranteeing public transport and creating pedestrian-friendly urban spaces. This paper aims to identify the walkability drivers in urban areas and investigate walkability behavior. The survey was carried out in southern Brazil, with a sample of 439 respondents. Data were subject to factorial analysis, regression analysis, and variance analysis. The analysis revealed four walkability drivers that explain pedestrian behavior: (i) infrastructure, (ii) traffic conditions and behavior, (iii) built and natural environments, and (iv) social relations. The results show that built and natural environments and social relations were the most significant aspects in explaining walkability's overall perception. Concerning socio-demographic aspects, the study points out that (i) men feel safer than women when walking in the neighborhood; (ii) the presence of trees and attractive places along the street increases the walking behavior of nonsedentary people; and (iii) the perception of the neighborhood's beauty increases with age. The research provides contributions regarding understanding the interrelated aspects of walkability behavior. Finally, the study offers relevant evidence for social researchers and urban planners by identifying walkability drivers and supporting political and academic debate elements. [ABSTRACT FROM AUTHOR]

The issues of sustainable and green development is becoming more important, both in scientific analyses and in city policies. The aim of this article was to attempt to create The Green Polish Cities Index. The Index consists of two main parts - Sustainable Development and Green Development, and was based on a review of previous indices and the OECD typology - the PSR (pressure-state-response) model. The article compares and critically analyzes 6 indices used by the European Environment Agency, OECD or other European Units. The selection of indices was connected with a wide application and the diversity of variables used. In total, 226 variables were analysed. Due to a lack of comparative research for Polish cities, The Green Polish Cities Index was constructed. The Index consists of 31 variables representing the most important dimensions of a green and sustainable city. The availability of data and specific conditions of Polish cities were taken into account. An overview of indices and preparation of The Green Polish Cities Index led to the conclusion that implementation of the green city idea under Polish conditions requires, amongst other things, greater cooperation between the Central Statistical Office, universities and city decision-makers.

Abstract In this article, we initially present and discuss the existing concepts covering sustainable and healthy cities, and urban metabolism infrastructure. The urban metabolism infrastructure distributes a wide range of key resources to citizens through various modes of transportation. Although the technical infrastructure and people in cities tend to be perceived as separate systems, they need to be acknowledged as co-dependent. Thus, co-creating urban metabolism and its infrastructure should be an integral part of developing a healthy city. We use mobility and transportation examples from the Cities-4-People project as a case to discuss the role of citizens and local stakeholders in co-creating solutions to improve their cities’ mobility through the urban metabolism and sustainability lens. Furthermore, we discuss the project process outcomes, leading to a set of guidelines towards achieving healthier cities.

The focus of this study is the impacts of smart-technology motorcycle-taxi services in some parts of Nigeria. The purpose of the study is to evaluate the socio-economic impacts of the smart-technology transportation and logistics operators in the selected study areas in order to improve their service delivery. The study was motivated by the public complaints around the informal motorcycle-taxi arrangements in the study areas and the subsequent introduction of modern smart-technology assisted transportation models, with the intension to advance the public transportation in the areas under consideration. The target smart-technology companies under investigation are GOKADA, SafeBoda and KONGA. This work will analyze the opinions, preferences and demographic characteristics of five categories of the stakeholders involved in the smart-technology businesses under focus. The stakeholders are regular passengers, irregular/occasional passengers, regular order recipients, irregular order recipients, and bike drivers. The empirical data collection of this study consists of survey and interviews of participants with a profound understanding of the smart-technology transportation. A survey was conducted among two hundred and thirty endusers and operators of smart-technology motorcycle-taxi system in the two commercial cities of Lagos and Ibadan, Nigeria. The sharing proportions of questionnaires among the respondents in the study areas was informed by the preliminary information and recommendations of stakeholders, as follows; Ibadan (45%), Lagos (55%). The survey was conducted using structured and unstructured questionnaires. All the interviews were transcribed, analyzed, compared with other existing cases, presented through descriptive statistics and conclusions drawn using PEST and SWOT analyses. The results from this study will give an understanding of the activities and impacts of the three smarttechnology based motorcycle-taxi companies in the selected study areas, towards the sustainable transportation and logistics services. The results from this work show that the introduction of smart-technology motorcycle-taxi system has helped businesses grow in the study areas and should be given support by the government. Youth participation in the smarttechnology transport system will boost the economy and provide jobs for the teaming youths. Women involvement and confidence in the new transport arrangement is a welcome development and is commendable. In view of the foregoing, more research work should be conducted on the activities of other smart transport companies for more positive impacts. The service providers are implored to extend their services to other high impact areas like health and accident related ones. [ABSTRACT FROM AUTHOR]

Smart cities continue to be conceived and implemented around the world as literature documenting these trends grows at a similar pace. Practices focused on narrow techno-economic objectives have met with sharp criticism as scholars have called for human-centred smart cities that explicitly address social issues and the needs of residents. Yet, literature has made few attempts to systematically compare a representative sample of smart city practices and discussions using objective methods that combine quantitative and qualitative approaches. This study thus focuses on Sweden and Japan as two nations particularly active in the implementation and discussion of smart cities. To compare the state of discussions and practices in each country, we examine a sample of almost 2,000 academic studies published since 2010. Using co-occurrence network analysis (a type of content analysis), we objectively identify the thematic foci of discourse and practices in each country. We then explore the themes characterising each country's network with qualitative descriptions from the sampled literature. Our analysis reveals unique trends in both countries related to the conceptual framing of smart cities, participation of local government and citizens, and differing interpretations of vulnerability to hazards. Overall, combined findings from both countries reveal that technology-focused discussions are dominating over social topics, such as human capital, stakeholder participation, governance, social equity and so forth. The absence of socially oriented research is more pronounced, however, in Japan. These findings provide important cues for future smart city research, policy and practice. [ABSTRACT FROM AUTHOR]

In this article, we analyse how bathing practices and facilities have been a part of a long history in Île-de-France and have never totally disappeared despite their decline in the second half of the 20th century. We then try to determine what motivated the actors in the Paris bid for the Olympic and Paralympic Games to promise the opening of twenty or so bathing sites by 2024. The inclusion of the Seine in the bid project makes it possible to further develop urban strategies which are already underway. At the same time, the development of open water swimming as a sport offers an exceptional opportunity to showcase the architectural and natural heritages of cities hosting the games. Finally, the evolution of bidding models and their popularity leads committees to promise to provide intangible and symbolic legacies for the benefit of inhabitants and international actors and audiences alike.

The aim of this paper is to develop a system-level dynamic indicator for testing the long-term effectiveness of planned projects in a system. The indicator developed in this paper is a system dynamics model, which adds a dynamic component to the static structure of the flow matrix of Ecological Network Analysis (ENA). It offers the capability to tailor the model to the condition of individual systems.The paper creates a resilient energy-flow structure for Cone Spring Watershed and uses the table of results formulated in the article “Ecology-related resilience in urban planning – a complex approach for Pécs” (Kiss and Kiss, 2018), in which a method based on ENA was developed which helps with the creation of a resilient and sustainable system. A general system dynamics model – adding dynamics to an arbitrary static resilient structure - is developed first. The practical use of this dynamic indicator is demonstrated by means of an ecological example (Cone Spring Watershed) and a non-ecological example (the resilient and sustainable city strategy of Pécs, Hungary). The model is able to test the long-term effectiveness of the planned investment strategies and allocates the investment budget accordingly.

This article contextualizes the smart cities paradigm in the panorama of contemporary city challenges, which increasingly encompasses the pursuit of sustainable development goals and the need to incorporate urban resilient behaviors, mainly in response to the impacts of climate change. Such a scenario also comprises the interpretation of smart cities as tools to assist policymakers and city administrators in directing solutions based on emerging information and communication technologies (ICTs) to the materialization of urban strategic plans addressing these confrontations. There are, however, no established indicator systems that attest to the substantiation of such plans by smart city solutions, nor to their alignment with the goals of urban sustainable development. Therefore, an analytical framework is proposed here to address this knowledge gap. It enables guiding the leverage of smart cities’ ICTs, not only for the achievement of economic goals, a feature intrinsic to smart city innovations, but also to reach other sustainability dimensions, as the environmental, social, institutional and cultural. To this end, generic sustainability indicator frameworks and also a set of smart city indicators are explored. They are examined as potential sources of specific taxonomies in smart city services for urban sustainable development. From this compilation of options, the Dashboard of Sustainability, once one of the indicator systems most recommended by experts, is revisited. It is adapted as a framework for analyzing and helping to maintain the strategic targeting of smart city solutions, during their entire lifecycle, at sustainability. To complete the qualitative-analytical-taxonomic frame, the services offered by a real smart city solution, the Rio de Janeiro Center of Operations, are employed as a model. This allows investigating its 9-year transition from a wider, larger capacity, strategic and innovative configuration in orientation towards sustainability perspectives, to a more narrow, operational composition, that is predominantly devoted to the economic dimension.

The aspired potentials of the "Smart City" (SC) and its deficits in practice are essential reasons why the subject is assigned to a rapidly growing body of literature. This situation requires a specific review of the literature summarizing the research efforts to date into research branches and topics, unifying essential basic concepts and thus forming a solid basis for further research. The present study first derives a basic structure of research by an analysis of the available literature reviews. Subsequently, a systematic examination of SC literature by means of an EBSCO data query identifies the current research topics and compiles a comprehensive view of the research topics. The present study is therefore not only of interest for scientific use, but also offers practitioners an overview of the various sub-areas of a SC, as well as of the currently available findings and experiences in relation to the implementation of SC (sub-)projects.

• An integrated multigeneration system with battery and hydrogen storage is proposed. • During charging mode, 25.5 MWh of solar energy is generated from the PV field. • The hydrogen storage results demonstrate a round-trip efficiency of around 45.5 %. A novel integrated energy system, where tri-renewable energy sources are coupled with a battery and hydrogen storage system, is proposed. The objective of this paper is then to investigate and evaluate the overall system thermodynamically for potential applications. Solar, biomass and wind energy sources are considered in the system development, and the potential needs of the community including electricity, heat, and hot water are fulfilled. A fraction of the renewable solar energy is stored in the form of hydrogen to operate the system during the off-peak time. The stored hydrogen is then employed to operate a proton exchange membrane (PEM) fuel cell, and electrical energy is produced for the charging station. Several sensitivity analyses are performed to demonstrate the effectiveness and feasibility of the H 2 storage system. The share of H 2 power to power (P2P) solution increases from 18.5 % at a photovoltaic (PV) area of 250 m2 to 45.4 % at a PV area of 500 m2. During the charging mode, around 25.5 MWh of excess solar energy is generated from the PV field. The deployment of 500 m2 can generate 769 kg of hydrogen that is stored in the hydrogen storage tank, and it can generate 18.4 MWh of energy from the PEM fuel cell. The calculated hydrogen storage results demonstrate a competitive round-trip efficiency of around 45.5 %. [ABSTRACT FROM AUTHOR]

This paper investigates the opportunity to plan for a novel on-demand freight delivery service in urban areas with tight service and sustainability requirements. This contribution first attempts to focus on the feasibility of connecting people and freight mobility through the joint usage of transportation options. It builds on the hyperconnectivity principles enabled by the Physical Internet (PI) manifesto for city logistics, referred to as HCL (Hyperconnected City Logistics). To this end, this paper proposes a model-based decision support approach that seeks to produce effective delivery solutions for an on-demand multimodal transshipment problem. The approach considers multiple mobility options such as on-demand urban delivery services, cargo bikes, tramways, and buses to transship goods from one urban logistic hub to another. This novel short-term response planning problem complements the well-known day-before planning problem. The objective function aims to minimize the impact of freight moves in the time and space of urban transport networks. The proposed solution aims to increase the sustainability of cities by reducing congestion levels, the impact of logistics moves, as well as carbon emissions in urban areas. An illustrative case is provided to demonstrate how the novel multi-mode transportation system could operate and to provide an evaluation of the economic and sustainability benefits of such a system in an urban context. For a hyperconnected network, the impact of freight movements on the time and space of urban transport networks can be reduced by 91%. The results demonstrate the potential of urban synchromodality in improving economic efficiency, service capability, and sustainability. [ABSTRACT FROM AUTHOR]

Public policies implemented by the Brazilian government for the promotion of urban agriculture were examined. Urban agriculture contributes to combatting problems related to food security and environmental issues in cities. In Brazil, the Ministry of Social Development initiated the elaboration of a policy to support urban agriculture, having listened to different segments of society. Moreover, the Brazilian Senate intends to establish the National Policy of Urban Agriculture. A pilot project for a city in Amazonia considers the urban farmer's socio-economic vulnerability, gender equity, rational use of urban land, technical assistance, and environmental education. The urban agriculture policy in Brazil represents a significant advance in sustainable cities and explores the potential to be applied to urban vacant land and its contribution to food production, inclusion, and social justice. • Urban agriculture in Brazil is regulated at National, regional and municipal scales. • A pilot project in Amazonia was used for environmental education extension. • The urban agriculture policy in Brazil contributes to inclusion and social justice. • Urban agriculture alleviates food security issues in Brazil.

Summary: This synthesis article presents an overview of an urban metabolism (UM) approach using mixed methods and multiple sources of data for Los Angeles, California. We examine electric energy use in buildings and greenhouse gas emissions from electricity, and calculate embedded infrastructure life cycle effects, water use and solid waste streams in an attempt to better understand the urban flows and sinks in the Los Angeles region (city and county). This quantification is being conducted to help policy-makers better target energy conservation and efficiency programs, pinpoint best locations for distributed solar generation, and support the development of policies for greater environmental sustainability. It provides a framework to which many more UM flows can be added to create greater understanding of the study area's resource dependencies. Going forward, together with policy analysis, UM can help untangle the complex intertwined resource dependencies that cities must address as they attempt to increase their environmental sustainability.

Smart city concept or label has become increasingly popular in scientific literature as well as in contemporary urban policy-making, where it has been popularized for the purpose of solving complex urban problems. This paper focuses on the review of the existing literature on this concept, following mainly manifest content analysis approach. The scrutinisation process reveals that this concept has been indeed popularized recently, overtaking (and substituting) some more older concepts, which could be partly contributed to its terminological neutrality and broader content that it tries to address. However, the main practical impetus for the growth of popularity can be attributed to the technology push. The increase in the volume of research partially also reflects the availability of research funds, thus indicating that smart city investigation is also policy-driven topic. Following a trajectory, a potential for the new city label emergence in the future should not be disregarded.

The university as a knowledge-intense space-also referred to as the brain of the city-is one of the key urban factors whose role is gradually being repositioned in the city and society during its social and urban transformation. New concepts of cities have entered professional discourses, and six categories were found to be conceptually distinct enough to be seen as supported by a specific body of theories. The research goal for this study is to define three of these-the sustainable city, smart city and resilient city—and the evolving university-city co-influencing relationship. The main methods used for this study are the analytical and descriptive methods, and the research materials are drawn from wide-ranging literature, such as books, research articles, published analyses, reports, urban plans, and other documents. We draw a conclusion that universities are vital urban actors in terms of sustainable, smart and resilient developments. Through two case studies, including University of Prishtina, dimensions of campus ecosystems critical to sustainability and resilience are highlighted, which should be a component of any comprehensive future spatial development of the university.

This work is an experimental study focusing on the relationship between street morphology and thermal storage in buildings. The first aim of this study is to reduce air conditioning usage in hot and arid areas, taking as example Biskra city (Algeria), during the long summer period (5 months), by reducing thermal storage. This leads to the reduction of carbon emissions to a level higher than the individual construction level in order to design a sustainable city, using measuring instruments (kimo HD 100 and Cason CA 380), we measured outdoor air temperature, wall temperature, relative humidity and wind speed on three street morphologies ; the (canyon, dihedral and open streets). These streets are different in terms of morphological indicators such as Sky View Factor (SVF) and albedo materials (a). We also applied mathematical equations across the thermal balance to calculate thermal storage. Our second goal was to identify the morphological indicators of the streets affecting the thermal storage of buildings. In this context, the obtained results showed that SVF was the most influential parameter on the heat storage.

The process of adaptation and adoption of modern values by multicultural urban communities raises various problems, especially those related to the environment. In Surabaya and Sidoarjo, even though the Surabaya City Government and the Regional Government of Sidoarjo have carried out various environmental programs, the demands of a fast and practical modern lifestyle create egocentric and anthropocentric attitudes. Urban communities must take on the continuous socialization of ecocentric behavior that adopts modern values but must also maintain the value of local wisdom to support the realization of sustainable city. The family-based collaborative eco-literacy model is needed as a strategy to develop green living cultural values that can be practiced by all levels of society in various regions with different characteristics in both cities. This model directly touches the family as the main place to cultivate ecocentric mindset and behavior. Another consideration is that there is few government policies related to environment that directly target the family. This study illustrates how the family-based collaborative ecoliteracy model was applied to families in Surabaya and Sidoarjo and explains how the model has moved the attitudes and behavior of these families to those in line with ecocentric principles. By using a qualitative-descriptive approach, this model was applied to 16 families selected according to participant criteria. The subsequent changes in behavior were observed over a period of six months. The results of the application of the model show that each individual in the family collaborates and strengthens due to collective competence, which is an ecocentric value. Based on the orientation of green living values in eleven sustainable urban components, it can be concluded that almost all green city programs carried out by the government are intended to realize Surabaya and Sidoarjo as sustainable cities.
