This paper reviews the literature on urban sustainability with the objective of drawing more attention to the social aspect of sustainability in urban planning. Given that social capital is a crucial component of moving towards more progressive smart cities and urban innovation, it is important to investigate the social dimension of sustainability and the opportunities that just cities can bring to improve the quality of life for urban dwellers. This paper is divided into three sections. The initial section provides an introduction to urban sustainability, discussing the historical roots of sustainability and sustainable development ideas, the three fundamental elements of sustainability, and the process of defining and measuring sustainability in an urban setting. Moving on to the second section, it delves into the body of work related to linking urban sustainability with urban strategies. The third section finally addresses the emergence of literature on just sustainability and just cities, which can give valuable insights to city policymakers who are trying to improve balanced sustainability.

Applying the criteria regularly used in sustainability assessment of "ordinary" buildings leads to the observation that tall buildings are "not sustainable." But nothing is ordinary about tall buildings and such an evaluation is not appropriate. While tall buildings may not measure up to the same sustainability standards applied to not-tall buildings, they do indeed have a significant sustainability impact if assessed within their appropriate context. This paper promotes the idea that in evaluating "sustainability" of tall buildings, we must look at their sustainability impact beyond their physical boundaries and within the urban context.

The purpose of this paper is to review relationship between spatial characteristics of compact city and urban sustainabiliy from system dynamics perspective using causal loop analysis. It has been argued that spatial characteristics of compact city, high population density and mixed land use, are positively related to urban sustainability. However, research results that are not consistent with pros of compact city argument have been accumulated too. It is especially true when spatial characteristics of compact city are examined with regard to each dimension of sustainablility: economic, social, and environmental sustainability. Reviewing each dimension of sustainability with regard to spatial characteristics based on causal loop analysis, this paper provides more clear understanding on relationship between compact city and sustainability. Also this paper provides a base for system dynamics simulation for future study.

Underground infrastructure systems provide essential public services and goods through buried structures including water and sewer, gas and petroleum, power and communication pipelines. The majority of existing underground infrastructure systems was installed in green field areas prior to development of complex urban built environments. Currently, there is a global trend to escalate major demand for underground infrastructure system renewal and new installation while minimizing disruption and maintaining functions of existing superstructures. Therefore, Engineers and utility owners are rigorously seeking technologies that minimize environmental, social, and economic impact during the renewal and installation process. Trenchless technologies have proven to be socially less disruptive, more environmentally friendly, energy conservative and economically viable alternative methods. All of those benefits are adequate to enhance overall sustainability. This paper describes effective sustainable solutions using trenchless technologies. Sustainability is assessed by a comparison between conventional open cut and trenchless technology methods. Sustainability analysis is based on a broad perspective combining the three main aspects of sustainability: economic; environmental; and social. Economic includes construction cost, benefit, and social cost analysis. Environmental includes emission estimation and environmental quality impact study. Social includes various social impacts on an urban area. This paper summarizes sustainable trenchless technology solutions and presents a sustainable construction method selection process in a proposed framework to be used in urban underground infrastructure capital improvement projects.

The realities of Climate change and its untold implications on the livelihood of man are no longer new worldwide. In attempts to subdue the negative implications of Climate change scenario globally, several measures have being suggested and being put in place. One of such measures is urban reforestation especially in the developing nations where forest resources have extremely and uncontrollably exploited. Most of cities in developing nations are almost devoid of regularly maintained trees for whatever purpose. Thus, the enormous roles which urban tree performs are lacked in most cities. In order to subdue excessive heat in cities arising from exposure of urban land areas urban reforestation exercise needs to be embarked upon. The investigation was carried out through desk studies and review of relevant publications to examine what it entails to have a sustainable reforestation programme in cities. The study revealed that several factors need to be taken into consideration if sustainable urban reforestation will be achieved, especially in developing countries. These factors include urban soil nutrients status investigation, appropriate tree type study, public perception about the tree types, relevant legal instrument to achieve successful reforestation exercise in cities among others were found to be salient to this exercise. Urban reforestation has enormous potentials to subdue Climate change consequences, including urban renewal if adequate provision is made for its sustainability, especially in developing countries. To ensure this is realized it is recommended that relevant ministry/agency could be put in charge for the maintaining, cutting and replanting of urban tree and all that are involved in urban tree sustainability.

주택문제, 도심 오픈 스페이스의 감소, 난개발, 교통체증, 도심쇠퇴와 같은 문제점을 겪고 있는 현대도시의 지속가능성을 논의함에 있어서 도시성장관리는 지방자치정부의 차원에서 중요한 이슈중의 하나이다. 이러한 지속가능성을 가능케 하는 실천전략으로 본 연구에서는 스마트성장의 개념을 살펴보았다. 또한 도시의 지속가능성에 가장 큰 걸림돌 중의 하나는 지속가능한 전략을 일관성 있게 추진할 수 있는 선순환 구조가 결여된 자치단체의 내부구조상의 문제점을 들 수 있다. 본 연구에서는 지역혁신시스템(RIS)에 기반하여 각종 도시성장관리 전략에 있어서 지속적인 선순환 구조를 가능케 할 수 있는 지방정부조직의 개념적 모형을 제시하였다.

The purpose of this study is to assess the sustainability in 45 cities of all over Gyeongnam and Gyeongbuk using weights and assessment system developed in leading research. The materials of assessment used statistical data and spatial data were standardized for the systematic result. The assessment score was established using the normal distribution from 25 to 125 for removal of the very smallest and maximum value. According to the results, Tongyeong was assessed the highest by 82.5 score in environmental sustainability index. In economical sustainability index, Pohang, Gumi, Changwon, Yangsan were more than 79 score but Busan, Daegu, Andong were less than 70 score. Ulsan, Geoje, Yangsan were assessed higher in society-institutional sustainability index and Jinju, Munkyeong, Changnyeong were showed higher than other cities by more 79 score in quality of life(QOL)'s sustainability index. In case of integrated sustainability index, Jinju that was the highest sustainability in QOL was assessed by first city. However, Ulsan was assessed the lowest city among others. Therefore cities which have high sustainability will prepare a politic investment program for maintaining current conditions. Cities which have low sustainability will grasp closely the environmental characteristics of urban and present the improvement direction through monitoring continuously. Overall, these results can be used as tools to assess the current cities and predict the future one. It is also necessary to establish a systematic urban planning for livable and sustainable city.

The present study illustrates a method for monitoring the urban vegetation around Shaoxing city, Monitoring spatiotemporal changes in urban areas will become increasingly important as the number and proportion of urban residents continues to increase. The synoptic view of urban land cover provided by satellite and airborne sensors is an important complement to in situ measurements of physical, environmental and socioeconomic variables in urban settings. The results obtained have revealed a notable change in the vegetation cover in and around the City premises. In this study, we discussed methodology for measurement of urban vegetation and vegetation distributions based on band ratioing in Shaoxing city using Land sat TM imageries. A systematic analysis of the spatiotemporal dynamics of vegetation in urban areas is required to ensure a healthy sustainable environment.

This paper presents the initial findings of a ground-breaking two-year CTBUH-funded research project investigating the real environmental and social sustainability of people's lifestyles in a number of high-rise residential towers in downtown Chicago, and a comparable number of low rise homes in suburban Oak Park, Chicago - based on actual energy bills and other real data. The study is ground-breaking because, to date, similar studies have been mostly based on very large data sets of generalized data regarding whole-city energy consumption, or large-scale transport patterns, which often misses important nuances. This study has thus prioritized quality of real data (based on around 250 households in both high rise and low rise case studies), over quantity. In both urban and suburban cases, the following factors have been assessed: (i) home operational energy use, (ii) embodied energy of the dwelling, (iii) home water consumption, (iv) mobility and transport movements, (v) urban/suburban Infrastructure, and (vi) quality of life. The full results of this seminal study will be published in the form of a CTBUH Research Report publication in 2017. Presented below is an overview of the initial (and, currently, unverified) findings of the research, together with the limitations of the study that should be taken into account, as well as future plans for developing this important pilot study.

이 논문의 목적은 도시 성장의 패러다임이 양적 성장에서 질적 발전으로 전환되어야 한다는 문제의식에서 사회적 지속가능성의 담론을 고찰하고 실천적 과제를 탐색하는 데 있다. 그간 한국의 도시성장은 질적인 발전을 외면한 채 양적 팽창에 중점을 두어왔고, 그 결과 총량적 부는 달성하였지만 도시 빈곤과 사회적 양극화, 복지와 삶의 질 악화 등 도시 내 사회적으로 지속가능하지 못한 문제들을 양산해왔다. 이에 사회적 지속가능성은 형평성을 근간으로 도시민의 사회적 필요를 충족시키고, 사회적 발전이 지속되는 데 관심을 가진다는 점에서 도시 발전의 불평등과 분배 문제에 중요한 의미를 갖는다. 아울러 사회적 지속가능성은 내발적 주체로서 도시민의 역량을 강화하고 거버넌스를 증진하는 기제가 될 수 있다. 지속가능한 발전에 관한 논의에서 출발한 사회적 지속가능성은 서구 학계를 중심으로 점차 그 중요성이 부각되면서 개념과 실천적 과제가 연구자에 따라 다양하게 논의되고 있는 한편, 국내에서는 아직까지 사회적 지속가능성에 대한 관심이 부족하고 제도적 장치가 불비하다. 그럼에도 사회적 지속가능성의 개념과 실천적 과제들은 오랜 기간 양적 성장 위주로 발전하면서 그 모순이 누적되어 온 한국 도시의 향후 발전 경로에 시사하는 점이 크다.
