The success of urban sustainability is very much dependent on a number of human factors. Therefore, it becomes even more important to explore how people understand urban sustainability and how they behave accordingly. Based on a formerly developed conceptual framework and on specified influencing factors, this study aimed to evaluate and elucidate the urban sustainability understanding and behavior of individuals in the city of Istanbul. This was assessed through the use of a quantitative questionnaire survey of 535 respondents. Therein, socio-psychological processes of sustainability understanding (i.e., determinants of awareness, perception, and attitude) and sustainability behaviors along with personality traits and influential factors were assessed and analyzed through the use of bivariate and multivariate methods (i.e., correlation tests, ANOVA, t-tests, and multiple linear regression). The results showed that sustainability awareness was more strongly correlated with attitude than perception, whereas behavior was found to be strongly correlated with both awareness and attitude and was (significantly) predicted by all determinants. The associations/influences of personality traits with determinants were found to be mostly insignificant. Conversely, for behavior, they were significant. The most influential factors found (in hierarchical ordering) were awareness of consequences, trust in society, social appraisement, world-mindedness, willingness to pay, trust in science and technology, ascription of responsibility, age and gender.

This paper reports on a systematic review of the literature around governance and water infrastructure in England to analyse data on the application, or absence, of justice themes. It finds that, unlike in other sectors, justice thinking is far from embedded in the water sector here and whilst there are signs of a discussion there is a lack of sophistication and coherence around the debate. More positively, the research suggests that the concept of justice can be used as a tool or framework to help air and address these complex issues and in doing so is an advance on the concept of sustainability. By exploring the issues in this way, the study reveals a wealth of opportunities to use justice-thinking to improve infrastructure decision making. It is suggested a justice approach is the next step as our thinking matures beyond sustainability, improving the decisions we make for people and planet.

Congestion has become part of everyday urban life, and resilience is very crucial to traffic vulnerability and sustainable urban mobility. This research employed a neural network as an adaptive artificially-intelligent application to study the complex domains of traffic vulnerability and the resilience of the transport system in Nigerian cities (Kano and Lagos). The input criteria to train and check the models for the neural resilience network are the demographic variables, the geospatial data, traffic parameters, and infrastructure inventories. The training targets were set as congestion elements (traffic volume, saturation degree and congestion indices), which are in line with the relevant design standards obtained from the literature. A multi-layer feed-forward and back-propagation model involving input–output and curve fitting (nftool) in the MATLAB R2019b software wizard was used. Three algorithms—including Levenberg–Marquardt (LM), Bayesian Regularization (BR), and a Scaled Conjugate Gradient (SCG)—were selected for the simulation. LM converged easily with the Mean Squared Error (MSE) (2.675) and regression coefficient (R) (1.0) for the city of Lagos. Furthermore, the LM algorithm provided a better fit for the model training and for the overall validation of the Kano network analysis with MSE (4.424) and R (1.0). The model offers a modern method for the simulation of urban traffic and discrete congestion prediction.

Social, environmental, and economic problems related to urban living have surpassed the agenda of policy and decision-makers as well as general public opinion in recent decades. To address urban and environmental issues, it is pivotal to examine how people think, feel, judge, and act with respect to sustainability. While some prominent theories exist and various attempts have been made to propose synthesized models, there are still gaps and discrepancies within the literature of environmental psychological theories. As such, the aim of this paper is to critically review the literature by focusing on a few of the most influential environmental, prosocial, and psychological behaviour theories, which include Theory of Planned Behaviour (TPB), Norm Activation Theory (NAT), Value-Belief-Norm Theory (VBN), and the New Environmental Paradigm (NEP). The Scopus database has been searched systematically for the relevant studies. This paper concludes that an integrative approach to urban sustainability understanding and behaviour is needed. A framework is presented that consists of three layers of clustered components: (1) internal socio-psychological determinants, (2) personality traits, and (3) influencing external factors such as social, cultural, economic, and institutional factors. The model proposed in the study provides opportunities to further develop theoretical approaches and establish new measures of an Urban Sustainability Understanding and Behaviour assessment.

Global urbanization has the most tremendous negative effects on the changing landscapes in many developing countries’ cities. It is necessary to develop appropriate monitoring techniques for tracking transport space evolution. The work explores the impacts of urban growth dynamics of transport space over the past decades as a basis for predicting future space demands in Kano, Nigeria. Three epochs of Landsat images from 1984, 2013 and 2019 were processed, classified and analyzed. Spatial classifications of land-use/land-cover (LULC) types in Kano include transport space, built-up areas, vegetation, farmland, bare land and water. The data analysis involves model calibration, validation and prediction using areas using the hybrid modeling techniques—cellular automata-Markov (CA-Markov) in IDIRISI SELVA 17.0 and remote-sensing ARC-GIS 10.7 softwares. The result finds significant expansion of transport and built-up areas while other LULC receded throughout the entire study period. Predictive modeling of transport infrastructure shows spatial expansion by 345 km2 (3.9%) and 410 km2 (11.7%) in 2030 and 2050 respectively. Kappa reliability indices of agreement (KIA) classified images and ground maps were 85%, 86% and 88%, respectively, for 1984, 2013 and 2019 time series. The calibration quality met the 80% minimum suggested in literature for the spatial-temporal track and prediction of urban growth phenomena.

Urban Sustainability and Smartness Understanding (USSU) can be defined by a group of sociopsychological determinants (such as awareness, perception, attitude and behavior) which shapes the relationship between human beings and the environment in which they live. A variety of influencing factors must exist in relation to USSU, however, a comprehensive examination of these, looking at personal, social, environmental, economic, technical, and governance perspectives in an urban context, appear to be less well researched. As such this paper provides an exploratory and critical evaluation of the literature by focusing on the USSU determinants; with an aim toward identifying the key factors (and sub-factors) that are in relation with these determinants. Two big databases of Scopus and Web of Science—have been searched systematically for the relevant studies. Therein it is observed how these factors affect USSU according to the characteristics of the study. Sustainability focused studies were found to be more commonplace than smartness studies. Moreover, there is currently ambiguity in evaluating the impacts of the identified factors. This paper concludes that a holistic approach is needed for clarifying the relationship and causality between sociopsychological determinants on Urban Sustainability and Smartness context. A framework with six dimensions is presented to initiate future studies to develop a consistent; coherent and comprehensive methodology to assess an individuals’ USSU.

In Saudi Arabia, the carbon footprint and energy use that results from using concrete in construction is a major negative contributor to the environmental effects of building materials. Likewise, the impact of annual cooling and heating energy demands has an equally prominent role to play. These demands need to be assessed and benchmarked in order that reduction targets can be set. Saudi Arabia presents its own unique context and local conditions, which creates a challenge when utilizing generic frameworks for assessing the environmental impact of domestic buildings. In meeting this aim, this paper presents a resilience and environmental sustainability assessment framework (RESAF) developed specifically for domestic buildings in Saudi Arabia. RESAF helps designers/builders to minimize the carbon footprint of the building fabric and reduce in-use energy demands of domestic buildings in Saudi Arabia. This paper shows how this framework can be used to reduce, by approximately 23%, the carbon impact from construction materials, primarily by substituting a portion of cement for pulverized fly ash (PFA) or ground granulated blast furnace slag (GGBS). A reduction of 19% in annual cooling and heating energy demand were additionally achieved throughout the building’s life, simply by increasing insulation and using triple-glazed windows. The importance of passing these alternative solutions through the resilience filter is highlighted, not least questioning whether they are really fit-for-purpose.

Successful transitioning to a circular economy city requires a holistic and inclusive approach that involves bringing together diverse actors and disciplines who may not have shared aims and objectives. It is desirable that stakeholders work together to create jointly-held perceptions of value, and yet cooperation in such an environment is likely to prove difficult in practice. The contribution of this paper is to show how collaboration can be engendered, or discord made transparent, in resource decision-making using a hybrid Game Theory approach that combines its inherent strengths with those of scenario analysis and multi-criteria decision analysis. Such a methodology consists of six steps: (1) define stakeholders and objectives; (2) construct future scenarios for Municipal Solid Waste Management; (3) survey stakeholders to rank the evaluation indicators; (4) determine the weights for the scenarios criteria; (5) reveal the preference order of the scenarios; and (6) analyse the preferences to reveal the cooperation and competitive opportunities. To demonstrate the workability of the method, a case study is presented: The Tyseley Energy Park, a major Energy-from-Waste facility that treats over two-thirds of the Municipal Solid Waste of Birmingham in the UK. The first phase of its decision-making involved working with the five most influential actors, resulting in recommendations on how to reach the most preferred and jointly chosen sustainable scenario for the site. The paper suggests a supporting decision-making tool so that cooperation is embedded in circular economy adoption and decisions are made optimally (as a collective) and are acceptable to all the stakeholders, although limited by bounded rationality.

Circular economy principles aim to contribute towards sustainability and resilience through several simultaneous agendas including economic growth, social development and environmental responsibility. Stakeholders from each perspective have their own interests and priorities, which often result in conflict. There are several and varied methodologies which address the decision-making process, however in engineering spheres these techniques are usually limited to optimising resources, time or costs. Decisions that are comprehensive in scope and integrated across all affected systems are required to transition towards a circular economy, effective cross-disciplinary thinking is imperative and cooperation amongst diverse areas is essential. Game theory is a useful technique when analysing the interactions of stakeholders with multiple objectives and perspectives. This paper aims to critically review methodological approaches used in waste management practice and provide a guidance on how game theory differs from, and is complementary to, the primary decision-making tools available where cooperation is a feature too often missing. This review seeks to justify the development of game theory to complement waste management decision-making methods in civil engineering, where resource consumption and waste management is often voluminous. An application of game theory to a waste management example illustrates that this methodological approach is of complementary value. The contribution of this study to circular economy and solid waste agendas is to emphasise the capability of game theory to help facilitate conflict resolution, competition, and stakeholder consensus when capturing multiple (sometimes conflicting) values in line with circular economy principles.

This data article presents the UK City LIFE1 data set for the city of Birmingham, UK. UK City LIFE1 is a new, comprehensive and holistic method for measuring the livable sustainability performance of UK cities. The Birmingham data set comprises 346 indicators structured simultaneously (1) within a four-tier, outcome-based framework in order to aid in their interpretation (e.g., promote healthy living and healthy long lives, minimize energy use, uncouple economic vitality from CO2 emissions) and (2) thematically in order to complement government and disciplinary siloes (e.g., health, energy, economy, climate change). Birmingham data for the indicators are presented within an Excel spreadsheet with their type, units, geographic area, year, source, link to secondary data files, data collection method, data availability and any relevant calculations and notes. This paper provides a detailed description of UK city LIFE1 in order to enable comparable data sets to be produced for other UK cities. The Birmingham data set is made publically available at http://epapers.bham.ac.uk/3040/ to facilitate this and to enable further analyses. The UK City LIFE1 Birmingham data set has been used to understand what is known and what is not known about the livable sustainability performance of the city and to inform how Birmingham City Council can take action now to improve its understanding and its performance into the future (see “Improving city-scale measures of livable sustainability: A study of urban measurement and assessment through application to the city of Birmingham, UK” Leach et al.

Tree planting is widely advocated and applied in urban areas, with large-scale projects underway in cities globally. Numerous potential benefits are used to justify these planting campaigns. However, reports of poor tree survival raise questions about the ability of such projects to deliver on their promises over the long-term. Each potential benefit requires different supporting conditions—relating not only to the type and placement of the tree, but also to the broader urban system within which it is embedded. This set of supporting conditions may not always be mutually compatible and may not persist for the lifetime of the tree. Here, we demonstrate a systems-based approach that makes these dependencies, synergies, and tensions more explicit, allowing them to be used to test the decadal-scale resilience of urban street trees. Our analysis highlights social, environmental, and economic assumptions that are implicit within planting projects; notably that high levels of maintenance and public support for urban street trees will persist throughout their natural lifespan, and that the surrounding built form will remain largely unchanged. Whilst the vulnerability of each benefit may be highly context specific, we identify approaches that address some typical weaknesses, making a functional, resilient, urban forest more attainable.

Cities are contemporary metropolises that concentrate human and social activity; engineered to support and develop the physical environment and the people within it, Smart cities, we are led to believe, are the immediate future, where smartness is perceived as a characterisation of advancements or digitalisation, in government, mobility and sustainability. Therefore it is not surprising that many organisations are marketing their smart solutions and products, often to a ubiquitous extent and so called smart cities are striving to outperform each other. But how are smart cities actually being defined and how is performance being measured in an era where there is increasing access to unprecedented amounts of foreseen data? This paper identifies the plethora of the smart city definitions and categories evidenced from the literature and shows that 'Smart cities' lacks a robust coherent definition, with many contradicting facts within what constitutes a smart vision. Notably, almost every attempt from organisations, the European Union or cities themselves has failed to define 'smart' in objective terms that can be accepted globally. Certainly, they all are negotiating with a range of descriptors and smart ways to improve the city. Even the UK's attempts to develop a clear definition and set of standards for smart cities (i.e. PAS 180 and PAS 182) appears to suffer from fundamental differences in how the semantic content of a 'smart' city is defined. This paper demonstrates the necessity for a single 'Smart Cities' definition that deals with both the physical and digital using shared parameter value(s) that can be adopted and scaled amongst different localities and within a range of urban contexts adjusting according to existing city condition(s) and vision(s) setting the paradigm for further innovative research in this area.

The concept of sustainability and resilience has gained significant importance in recent years in the infrastructure engineering industry. Key challenges currently faced by the infrastructure industry worldwide include obsolescence, growing demands, climate change, increased vulnerability, demand for multifunctionality, and growing interdependencies among different asset types. With the recent changes in the economic, social, and environmental scenarios, an increasing pressure exists to develop robust, flexible, and multifunctional asset management solutions that not only suit the needs of the present, but also are safe, secure, and resilient to what the future may hold. Ultimately all infrastructure assets interact with the ground, and their integrity relies substantially on the performance of geotechnical assets, thus making geotechnical asset management a critical starting point in future proofing the infrastructure network. The paper highlights the need to devise resilient asset management solutions. The paper focuses on two transport modes, namely highways and railways, and aims to present an asset management framework that will test the resiliency of current geotechnical solutions to the plausible conditions of the future. The proposed asset management framework will enable strategic decision makers to evaluate the resilience potential of proposed geotechnical asset management solutions in light of future conditions with varying socioeconomic and environmental patterns.

This paper reviews the key issues relating to the increased future use of underground space where geoscientific information will be indispensable as a decision support tool for the sustainable development of underground space. A clear understanding of what is in the underground space (geology, utilities, etc.) and its properties are required to form a correct grasp of the potential assets and challenges of underground space as a resource. To inform urban developmental choices, regions having geological units that lend themselves to development or expansion of underground space use in the future will be given precedence over those with adverse geological conditions. Such information needs to be included into decision support systems for conventional types of underground construction. This paper establishes that a strong need exists to adopt computational visualization approaches in the form of GIS-based multicriteria decision analysis (MCDA). These provide a platform to enable the testing of underground space through a virtual experimental set-up of different uses, using a broad range of different yet divergent future scenarios to ensure that the core objectives of sustainable development are met.

University campuses, as owners and operators of their utility infrastructure, have generally taken a longer-term view of how utility infrastructure assets are placed below ground and therefore have a much greater appreciation for how such novel placement methods as Multi-Utility Tunnels (MUTs), a tunnel that houses more than one utility type, perform in the longer term (>50 yrs). This paper provides details of a 3 km MUT network built in the late 1950s and early 1960s that is currently undergoing considerable repair, refurbishment, modification and expansion to meet the demands of a 21st Century university campus. The paper discusses the sustainable advantages of adopting an MUT within a university campus providing lessons learned.

This paper explores the variety and timing of choices available to decision-makers during a redevelopment project for underground infrastructure space for utility services. The issues are explored using the Development Timeline Framework (DTF), a simple tool that makes explicit the importance of the timing of decisions and highlights when choices are locked-out or locked-in. It addresses the complex issues of trade-offs in decision making between various sustainable choices above ground and their requirement for underground space. The DTF enables the practitioner to optimize decision-making so as ultimately to mitigate future impacts, e.g. the potential effects of climate change and provide sustainable utility management practices, whilst enhancing community resiliency.
