This research aims to study a broad range of sustainability aspects and develop a set of indicators with their subjective relevance to each of the sustainability dimensions that will help to improve the sustainability level of the water system of Nur-Sultan (Kazakhstan).

The broader list of indicators (which were identified through a thorough review of the literature) was assessed by water-related industry professionals and experts who were asked to assess the compliance of suggested indicators to five criteria of sustainability using a Likert scale.

It was found that the highest-ranked indicators across all five categories were mainly related to the chemical and physical quality of water, followed by availability of individual water meters as well as water supply tariffs' adjustment to users' income, and issues of ageing infrastructure. The lowest-ranked indicators among all categories were mainly related to investments into research and development, water management and awareness, feedback systems and flexibility. The least ranked indicators are seen to be more related to the scenarios when basic needs are covered and the stakeholders have extra time and resources for advancing the levels of water infrastructure sustainability.

The ranked and categorized indicators can be used as a powerful decision-making tool to improve the sustainability of the water system of Nur-Sultan or any other city in a developing country.

By conducting this study, it was aimed to address the aforementioned gap in the field in terms of running a wider scope assessment of indicators rather than looking at conventional environmental and socio-economic aspects. This provides novelty to the study, especially in the context of developing countries that need more guidance in terms of sustainable development of the water-related infrastructure.

This study aims to examine exergy efficiency of engines and entropy performances at the flight process. In addition, the improvements that can be achieved in the system with the effective parametric controls of the engine have been evaluated in terms of both efficiency and entropy in the system.

According to the flight characteristics of the engine, the altitude-dependent irreversibilities and their environmental effects were discussed with two developed indicators, energy performance indicator (EPI) and sustainability indicator (SI).

According to the results of both indicators, the energy efficiency potential of the engine during the flight process was found to be 15.02%, while the fuel-based efficiency potential was 18.84%.

It is limited by the flight process of a Turboprop engine.

The management tools and criteria of entropy are very difficult model studies. The study offers an evaluable approach based on two basic criteria developed for engines.

In monitoring and review of entropy management related to fossil fuel technologies, key indicators developed can be used as benchmarks for managing emission sources

The two basic indicators developed can be used as monitoring measurement tools of sustainable energy and environmental performances for engines and applications.

The purpose of this paper is to present a mathematical model that illustrates the trade‐offs between sustainability, demand, costs, and profit in a supply chain with a single supplier and a single manufacturer.

It is assumed that a single product is produced and sold on a market where demand is sensitive to price and quality. Sustainability is treated as a quality attribute and is measured in terms of the levels of scrap and emissions generated in the supply chain. It is assumed that the emissions and scrap can be controlled by varying production rates or by investing in production processes. The impact of cooperative and non‐cooperative behaviour between the supplier and the manufacturer is explored. Numerical studies are used to illustrate the behaviour of the model.

The analysis shows that the supplier and the manufacturer can attract additional customers by controlling scrap and emissions. The behaviour of the supplier and the manufacturer are dictated by the decision criteria, such as changes in the level of sustainability, used by customers to evaluate the product. It is shown that the profit of the system is higher and that the level of quality is lower in the case of cooperation than in the case of non‐cooperation.

Several areas for future work are highlighted. The study of alternative demand functions, linking sustainability to a monetary component, including additional players, and incorporating additional sustainability indicators all offer possibilities for extending the model.

There is an identified need for analytical models that consider sustainability in the supply chain. The results are especially important for companies operating in markets where customers perceive the sustainability of a product as a quality criterion.

The study aims to build up knowledge for collateral exploration of the classical Delphi survey method for assessing the industrial sustainability-related correction factor using a real field study in Nigeria.

The paper elicits the character and the operational approaches using an example study to provide a critical review of the method. It estimates the correction factor for appraisal purposes by transforming expert opinion into a valid group consensus.

The work considers the specific parameters of the method, design and analysis for interpretation to prove the reliability and the validity for the research results. Moreover, it emphasises that the validity of the traditional Delphi research demands cautious theoretical and practical applications by the coordinating researcher. The paper establishes the current validity and effectiveness of the classical Delphi method of foresight and streamlines their efficient implementation for theory building despite its numerous weaknesses.

It explores desirable futures for the method while analysing what is possible and probable.

Sparse attention has been paid to the inevitable processes of change that enable progress in today's globalizing urban centres, but also threaten their unique identity, historic memory, and cultural heritage. The aims of this work are to understand the urban dynamics that trigger these change processes, uncover their effects, and discuss how these changes can be utilized to achieve sustainable development. The case study, which uses a comparative mixed method strategy consisting of archival research, fieldwork, and semi-structured interviews, is the Kosuyolu Housing Settlement, a project dating to the 1950s that represents one of Istanbul's best examples of urban development and housing culture. Displaying the architectural and urban planning ideals of the Modern period, this settlement is a concrete example that reflects the period's considerations regarding social housing. Through this case, change in housing has been evaluated in terms of sustainability indicators. The derived evidences show the significant role of governance and the maintained land use pattern for the achievement of the sustainable development and these evidences are used to suggest the development of an adaption guide that will assist in sustainable development in the short term, and the creation of alternative scenarios that are flexible and easy to adapt, active, and based on participatory processes for the long term.

A synthetic indicator (SI) is developed to measure the sustainability of tourist destinations according to four proposed dimensions of sustainable development: social, economic, environmental and political. Its purpose is to determine the most appropriate indicators for each type of tourist destination, i.e. which variables should be considered in each territory according to its typology (environmental, social, economic and tourism). To test the usefulness and employability of the SI, it has been applied in the Algarve (Portugal). Three destinations were analysed in this region: Albufeira, Faro and Lagos, all three good examples of the well-known sun and beach tourism model.

The SI is the result of a system of indicators. To reach the final result, a multi-criteria calculation has been used in which the most important variables that fit the territorial reality analysed have been included, based on an exhaustive analysis of more than 2,000 indicators proposed by various scientific studies and international organisations such as the United Nations World Tourism Organization. The results of this analysis have been weighted according to the opinion of the population. A survey of more than 1,800 questionnaires was carried out in tourist destinations with high seasonality and dependence on tourism in the Algarve, Portugal. Finally, the SI has been aligned with the Sustainable Development Goals (SDGs).

The level of sustainability and the level of social concern regarding tourism activity were defined. In the Algarve, tourism is transforming the landscape and the local economy, and overcrowding is perceived as an economic activity that negatively affects sustainability. The concerns of the resident population about the impacts of tourism have served to identify priority strategies to improve the level of sustainability of the destinations. The three territories analysed present different problems and therefore require different strategies for action, mainly of a local public nature. The final result indicates the level of sustainability of the destination, which allows specific actions for improvement in the short, medium and long term to be generated.

The results made it possible to develop lines of action aimed at improving the sustainable management of each tourist destination analysed. Involving the local population allows the residents of the destination to be part of tourism policies, assuming a bottom-up strategy. This research provides answers to destinations seeking to implement sustainable tourism, offering tourism sector managers tools for correct decision-making.

This research presents a SI based on a system of indicators adjusted to the needs of the territory to be analysed, takes into account the opinion of the local population as a weighting factor and is in line with the 17 SDGs.

本文根据为可持续发展提出的四个方面：社会、经济、环境和政治, 开发了一个综合指标（SI）来衡量旅游目的地的可持续性。其目的是为每一类旅游目的地确定最合适的指标, 即根据每个地区的类型 (环境、社会、经济和旅游), 应考虑哪些变量。为了测试IS的有用性和可用性, 它被应用于阿尔加维 (葡萄牙) 。在这个地区, 有三个目的地。阿尔布费拉 (Albufeira)、法鲁 (Faro) 和拉各斯 (Lagos), 这三个地方都是著名的阳光和海滩旅游模式的例子。

SI 是一个指标体系的结果。为了得出最终结果, 我们采用了多标准计算, 在对各种科学研究和国际组织（如世贸组织）提出的两千多个指标进行详尽分析的基础上, 将符合所分析的领土现实的最重要变量纳入其中。这一分析的结果已经根据民众的意见进行了加权处理。在葡萄牙阿尔加维（Algarve）季节性强且依赖旅游业的旅游目的地进行了1800多份问卷调查。最后, SI与可持续发展目标保持一致。

本文定义了可持续发展水平和社会对旅游活动的关注程度。在阿尔加维, 旅游业正在改变景观和当地经济, 过度拥挤被认为是一种对可持续性产生负面影响的经济活动。居民对旅游业影响的关注有助于确定优先战略, 以提高目的地的可持续性水平。所分析的三个地区出现了不同的问题, 主要是地方公共属性方面的, 因此需要不同的行动策略。最终的结果表明了目的地的可持续发展水平, 并为短期、中期和长期的具体改进行动提供依据。

这些结果帮助我们制定行动方针, 以改善所分析的每个旅游目的地的可持续管理。让当地居民参与进来这一种自下而上的战略, 可以让目的地的居民成为旅游政策的一部分。这项研究为寻求实施可持续旅游的目的地提供了答案, 为旅游管理者提供了正确决策的工具。

这项研究提出了一个合成指标, 其基础是根据要分析的区域的需要而调整指标系统, 考虑到当地居民的意见作为加权因素, 并且与17项可持续发展目标一致。

Se desarrolla un indicador sintético (IS) para medir la sostenibilidad de los destinos turísticos según las cuatro dimensiones propuestas para el desarrollo sostenible: social, económica, medioambiental y política. Su objetivo es determinar los indicadores más adecuados para cada tipo de destino turístico, es decir, qué variables deben considerarse en cada territorio según su tipología (ambiental, social, económica y turística). Para comprobar la utilidad y empleabilidad del IS, se ha aplicado en el Algarve (Portugal). En esta región se analizaron tres destinos: Albufeira, Faro y Lagos, los tres buenos ejemplos del conocido modelo de turismo de sol y playa.

El IS es el resultado de un sistema de indicadores. Para llegar al resultado final se ha utilizado un cálculo multicriterio en el que se han incluido las variables más importantes que se ajustan a la realidad territorial analizada, a partir de un análisis exhaustivo de más de dos mil indicadores propuestos por diversos estudios científicos y organismos internacionales como la OMC. Los resultados de este análisis se han ponderado según la opinión de la población. Se ha realizado una encuesta de más de 1.800 cuestionarios en destinos turísticos con alta estacionalidad y dependencia del turismo en el Algarve – Portugal. Por último, el IS se ha alineado con los Objetivos de Desarrollo Sostenible.

Se definió el nivel de sostenibilidad y el nivel de preocupación social respecto a la actividad turística. En el Algarve, el turismo está transformando el paisaje y la economía local, y la masificación se percibe como una actividad económica que afecta negativamente a la sostenibilidad. La preocupación de la población residente por los impactos del turismo ha servido para identificar las estrategias prioritarias para mejorar el nivel de sostenibilidad de los destinos. Los tres territorios analizados presentan problemas diferentes y, por tanto, requieren estrategias de actuación distintas, principalmente de carácter público local. El resultado final indica el nivel de sostenibilidad del destino, lo que permite generar acciones específicas de mejora a corto, medio y largo plazo.

Los resultados permitieron desarrollar líneas de actuación dirigidas a mejorar la gestión sostenible de cada destino turístico analizado. Involucrar a la población local permite que los residentes del destino formen parte de las políticas turísticas, asumiendo una estrategia ascendente. Esta investigación aporta respuestas a los destinos que buscan implementar un turismo sostenible, ofreciendo a los gestores del sector turístico herramientas para una correcta toma de decisiones.

sta investigación presenta un indicador sintético basado en un sistema de indicadores ajustado a las necesidades del territorio a analizar, tiene en cuenta la opinión de la población local como factor de ponderación y se ajusta a los 17 ODS.

This study aims to propose an integrated model involving concepts of sustainability and social innovation (SI) in higher education institutions (HEIs).

Based on a literature review, the authors were able to systematize sustainability and SI knowledge, in an integrated manner. Hence, the authors sought to develop a theoretical model that would integrate categories, indicators and sub-indicators, to review initiatives in HEIs in the sustainability and SI domains. The results indicated four major categories: mission, vision and values; curriculum; campus; and healthy environment. The integrated model was applied and validated in a Brazilian educational group, using the main corporate reports as data sources.

For the educational group analyzed in this study, the themes of sustainability and SI are explicitly and implicitly expressed in the mission, vision and values category. In the curriculum category, these themes are presented through the contents of cross-disciplines in all undergraduate courses, and also through outreach activities, integrating sustainability and SI in a theoretical and/or practical way. Regarding the campus category, the mention is explicit and the HEI works with initiatives aimed at achieving a “green” campus. In the healthy environment category, the educational group studied gives priority to the establishment of a safe and healthy work environment, focusing on labor rights and relations with society.

This work contributes to the advancement of research on the promotion of sustainability and SI in HEIs, proposing an innovative integrated model of analysis for the topics covered.

This study aims to identify and gauge the sustainability indicators (SUSIs) for sustainable Hydroelectric Power (HEP) project development. It examines major SUSIs under the social, economic and environmental (SEE) fronts and categorizes them under push and pull impacts which helps to identify challenges and opportunities associated with projects. Additionally, the study calculates an empirical sustainability index (SI) to assess the sustainability level of HEP. Finally, the study suggests mitigation measures across stakeholders, which will optimize government/developer/investor investments.

This paper examines the interaction of sustainable HEP development with SUSIs using Uttarakhand as a study area. Additionally, SI has been developed quantitatively. For the indicator classification, the authors conducted a literature review and secondary survey of all affected parties, including investors, developers, NGOs and villagers. The fuzzy logic theory (FLT) is used to determine the SI of the study area and classify projects in their level of sustainability. On the basis of expert opinion and literature review, mitigation measures are proposed across stakeholders.

The authors found that there is a mixed effect of SUSIs on HEP development across various projects in Uttarakhand. Furthermore, the authors suggest that index-based assessment and planned collaboration play a significant role in sustainable HEP development. Mitigation measures should be suggested to all affected stakeholders based on specific project issues, i.e. collaborations, training, public awareness campaigns, and initiatives by the government that would improve sustainability conditions.

In addition to supporting the ongoing and upcoming initiatives launched by the Government of India, including the Green Energy Corridor, independent power producers (IPPs); and the India-Renewable Resources Development Project with IDA and participates in Net zero target.

The structured, sustainable HEP planning suggested in the study will help to conserve society, economy, save resources and in parallel reduce the cost and time of developers and policymakers. This will also help to improve the socioeconomic status of the villagers and prolong the life of the project.

The innovative SI-based push-pull approach identifies a sustainable HEP project planning.

Implementation of a sustainability paradigm demands new choices and innovative ways of thinking. The main objective of this paper is to provide a meaningful sustainability assessment tool for make informed decisions, which is applied to higher education institutions (HEIs).

The objective is achieved by developing a quantitative tool for sustainability assessment using a driving force‐pressure‐state‐exposure‐effect‐action (DPSEEA) framework. The DPSEEA framework considers environmental, social, economic, and educational performance as main dimensions of sustainability. The proposed model is called DPSEEA‐Sustainability index Model (D‐SiM). The D‐SiM is a causality‐based model in which the sustainability index (SI) is an outcome of nonlinear effects of sustainability indicators in various stages of DPSEEA. To have an improved understanding of input factors (driving forces) and their impact on sustainability, a simplified empirical model is developed and applied to HEIs to determine the percent contribution of various driving forces on sustainability.

The study reveals that economic development, social equity, and education in sustainability are the major drivers for achieving sustainability in HEI, while health and safety issues, energy requirements, institutional enhancement, and international research and development trends are the less significant driving forces.

The indicators connected in DPSEEA framework through causal relationships lead to the quantitative assessment of sustainability, which provides a unique approach for informed decision making.
