<p>Building sustainable cities, as set out in the Sustainable Development Goals by the UN, requires sustainable urbanization as well as reducing per capita environmental impacts of living in cities. As a result of a growing population and constrained availability of building space, countries such as Switzerland are faced with increasing pressure on their land resources. They will need to considerably densify in existing urbanized areas to prevent urban expansion. Even though Swiss regulation promote inward settlement development and the creation of compact settlements, only limited analysis is available on the densification potentials combined with sustainability implications. We develop a geospatial explicit analysis framework which allows to up-scale the assessment and evaluation of densification potentials for the whole of Switzerland. An energy simulation tool is used for exploring impacts of different densification strategies on a district scale with respect to energy consumption.</p>

AbstractCities are recognised as central to determining the sustainability of human development. However, assessment concepts that are able to ascertain whether or not a city is sustainable are only just emerging. Here we review literature since the Sustainable Development Goals (SDGs) were agreed in 2015 and identify three strands of scientific inquiry and practice in assessing city sustainability. We find that further integration is needed. SDG monitoring and assessment of cities should take advantage of both consumption-based (footprint) accounting and benchmarking against planetary boundaries and social thresholds in order to achieve greater relevance for designing sustainable cities and urban lifestyles.

The Sustainable Development Goals identified by the United Nations (2030 agenda) aim to promote sustainable cities, the need to safeguard cultural heritage, and the importance of quality education. Through different projects, the DIDPATRI research group at the University of Barcelona has developed didactic iconographic models on the historical and heritage dimension of cities. Comprehensible proposals have been made by developing unique techniques and using easily accessible technologies. The working hypothesis has focused on the idea that the models of didactic iconography promote the understanding of the history of the city, and this enables educational actions and contributes to the formation of quality citizenship, aware of the importance of heritage, with a view to the sustainability of urban environments themselves. The components and the layout of the iconographic prototypes tested have been developed with the available technological variables, but, above all, they focus on the conceptual organization of the iconographic contents to show. In other words, it places greater emphasis on techniques than on subsidiary technologies for change. The development of different projects has generated models of empirical effectiveness, which methodologically have contributed to improving, in the key of sustainability, the knowledge of historical urban environments and respect for heritage. The case studies considered in this work are two of the most emblematic developed by the DIDPATRI group: the archaeological site of El Born in Barcelona, and the medieval site of La Seu de Urgell, in the Catalan Pyrenees.

This article aims to describe how the community service benefits young generations, especially students of high school in responding the trash problem in Pekanbaru. The fact that society including students did not possess enough awareness of the Sustainable Development Goals (SDGs) regarding thrash problem was the main reason for the community service event. The community service was conducted in the form of training and empowerment which emphasized the participants’ active engagement. The event has shown some positive outputs such as the participants’ understanding on trash problem and the SDGs’ goals as well as their awareness of role and contribution in creating free-trash environments. These are expected to meet two of the SDGs’ goals; sustainable cities and communities; and responsible consumption and production from non-governmental community side.

The concept of sustainable cities is based on a development paradigm that recognizes the rapid growth of urban population and makes an important contribution by forming a global urban plan. Sustainable city is organized in order to emphasize the importance of people and their needs. This paper will define what sustainable city is and show how certain innovative elements have been introduced in Copenhagen in order to achieve city sustainability. In that regard, an overview of innovative urban solutions in the context of environmental protection will be given. A comparative analysis of the achievement of the SDG 11 objective - Sustainable Cities and Sustainable Communities in Copenhagen will be carried out in relation to the other European Union capitals. The aim of this research is to determine whether Copenhagen is a sustainable city and how sustainable cities contribute to promoting the sustainable development goals. Finally, proposals will be made to achieve those objectives for other cities, based on the results achieved by the City of Copenhagen.

Studies have shown that comparison of strategies for sustainable cities in Asian countries is carried out through the prism of the international concept of sustainable development. The work builds a complex relationship between general and specific criteria for sustainable development of the urban environment in the strategies of individual Asian countries. Priority is given to management, socio-economic development, and environmental protection. Sustainable urban development guidelines are shown considering problems of poverty, environmental pressures, and drawing attention to environmental problems in cities. The particular countries (Bhutan, Myanmar and Cambodia) show guidelines for sustainable urban development, considering urbanization and population flows, the vulnerability of major population groups and addressing poverty and pressure on the environment. Analyzing the Sustainable Development Goals and internal strategies of Asian countries, the authors sought to determine the goals and objectives of creating sustainable cities, features of sustainable cities’ strategies in individual Asian countries and typical problems that arise on the path to sustainable urban development. The hypothesis of the study is the approach to sustainable cities through the prism of the concept of sustainable development with its socioenvironmental and economic components in their relationship and interdependence.
