ABSTRACT The mismatch between the fast-growing urban population and limited urban infrastructure has become a challenge in many emerging cities. The lack of affordable housing leads to burgeoning informal settlements and Manohara informal settlement in Kathmandu is not an exception. This study aims to investigate the current situation in Manohara informal settlement and examine the feasibility of floor area ratio (FAR) incentive in providing affordable housing. A household survey in Manohara informal settlement and simulation analyses of FAR incentive found the followings. Firstly, given the limited budget and little control over the land of Kathmandu by the government, a planning tool focusing on development gain is a suitable option for housing provision for low-income households. Secondly, FAR incentive simulation of land size of 50,000 sq. ft. in Kathmandu shows that 50%p incentive allowance can add 33–93% extra profit to the developers in a housing project, which can be secured for affordable housing for public interest.
快速增长的城市人口与有限的城市基础设施之间的不匹配已经成为许多新兴城市面临的挑战。缺乏负担得起的住房导致了非正式定居点的迅速发展,加德满都的Manohara非正式定居点也不例外。本研究旨在调查马诺哈拉非正式住区的现状,并探讨容积率激励在提供经济适用房方面的可行性。对马诺原非正式住区的入户调查和FAR激励的模拟分析发现:首先,考虑到预算有限,政府对加德满都的土地几乎没有控制,一个专注于发展收益的规划工具是为低收入家庭提供住房的合适选择。其次,土地面积为5万平方的FAR激励模拟。加德满都的一项研究表明,50%的激励补贴可以为住房项目的开发商增加33-93%的额外利润,这对于公共利益的经济适用房是可以保证的。

ABSTRACT Human existence is complemented by environmental sounds as by-products of people’s activities as well as intentionally generated sounds that allow human society to function, including transport and traffic sounds and notification sounds. The resulting soundscapes surround and permeate people’s daily existence. Technological, as well as behavioural change causes some of these sounds to become extinct at the local or universal level. While expressions of human communication through spoken words (language) and song are deemed to be heritage and thus formally collected and documented, there is a general lack of consideration of the heritage potential of anthropogenic environmental sounds. Focussing on examples from the state of NSW (Australia), this paper discusses sound loss in the urban heritage environment and advances two variations of a conceptual framework to assist heritage practitioners in decision-making to assess heritage potential in order to safeguard some of these sounds for the future.
作为人类活动的副产品的环境声音,以及人类社会运行中有意产生的声音,包括交通和交通的声音和通知的声音,是人类生存的补充。由此产生的声景环绕并渗透到人们的日常生活中。技术和行为的改变导致这些声音中的一些在当地或全球范围内灭绝。虽然人类通过口语(语言)和歌曲进行交流的表达被视为遗产,因此被正式收集和记录,但人们普遍缺乏对人为环境声音的遗产潜力的考虑。本文以澳大利亚新南威尔士州为例,讨论了城市遗产环境中的声音损失,并提出了两种概念框架的变体,以帮助遗产从业者在评估遗产潜力的决策中,为未来保护其中的一些声音。

ABSTRACT Circular development creates more resource efficient, adaptive, and ecologically healthy cities. Circular food and construction systems; the ecological regeneration of contaminated brownfield sites and circular tactical urbanism are just some of the processes and systems adopted by those implementing a circular development pathway. These produce benefits, however, there are many challenges to implementing circular development, demonstrated by two London cases. The research reveals the difficulties low-value, circular activities encounter when competing for space in London. It shows how the imbalance between local supply and demand for circular products prevents scaling-up. It suggest a lack of data monitoring the benefits of adopting circular development, undermines political support. It reveals the conflict between the reliance on civil society to engage with circular actions versus public resistance. It highlights the need for accountability and transparency in the process of implementation and for a regulatory framework to encourage circular development.
循环发展创造了资源高效、适应性强、生态健康的城市。循环粮食和建筑系统;受污染棕地的生态再生和循环战术城市化只是实施循环发展路径的一些过程和系统。这些产生了好处,然而,实施循环发展存在许多挑战,伦敦的两个案例证明了这一点。该研究揭示了低价值、循环活动在伦敦竞争空间时遇到的困难。它显示了循环产品的本地供需失衡如何阻碍了规模的扩大。报告指出,缺乏监测采用循环发展的好处的数据,削弱了政治支持。它揭示了依赖公民社会参与循环行动与公众抵制之间的冲突。它强调了在执行过程中需要问责制和透明度,并需要一个鼓励循环发展的管理框架。

ABSTRACT Community-led land ownership can contribute to environmental justice in disaster-prone areas, particularly as it protects vulnerable communities from market-driven displacement often occurring after natural disasters. The article reviews literature linking the climate emergency with disaster resilience and collective land-based models. It brings into focus the case of the Caño Martín Peña communities in San Juan, Puerto Rico, where residents started a Community Land Trust (CLT) in Latin America and the Caribbean, resulting from an extensive process of community participation. We highlight the importance of this case as still one of the only CLT’s in the Global South, a mechanism not yet sufficiently understood as a highly developed instrument for secure land tenure and adaptation to climate change in the Global South. We analyse the mechanisms by which the CLT’s collective tenure model effectively ensures greater environmental justice – both regarding ongoing flooding issues, and specific extreme natural events such as hurricanes. Collective land ownership allows residents to remain in the area despite forces of gentrification and displacement after disasters induced by global warming. We conclude with a reflection on the need for similar land-based solutions, and summon public authorities to consider these as a route to effective environmental management.
社区主导的土地所有权有助于灾害多发地区的环境正义,特别是因为它保护脆弱社区免受自然灾害后经常发生的市场驱动的流离失所。文章回顾了将气候紧急情况与灾害恢复力和集体陆地模型联系起来的文献。它聚焦于波多黎各圣胡安Caño Martín Peña社区的案例,当地居民在拉丁美洲和加勒比地区启动了一个社区土地信托(CLT),这是一个广泛的社区参与过程的结果。我们强调这一案例的重要性,因为它仍然是全球发展中国家仅有的CLT之一,这一机制尚未被充分理解为全球发展中国家保障土地权属和适应气候变化的高度发达的工具。我们分析了CLT的集体权属模式有效确保更大环境正义的机制——既涉及持续的洪水问题,也涉及飓风等特定的极端自然事件。尽管全球变暖引发的灾难造成了士绅化和流离失所,但集体土地所有权允许居民留在该地区。最后,我们反思了类似的陆地解决办法的必要性,并呼吁公共当局考虑将这些办法作为有效环境管理的途径。

ABSTRACT Discussions on the relationship between urban form and social capital have garnered attention for a long time as they are well documented in the literature. However, the empirical analysis regarding these two issues is still limited. This study proposes a new perspective on the link between the 3Ds (Density, Diversity, and Design) element of urban form and social capital in the global south using the Indonesian context. Using the linear multilevel regression, this study consistently revealed a contradicting result according to which greater residential density is negatively associated with several social capital factors. Surprisingly, more retail areas in cities are adversely associated with some social capital indicators. High connectivity did not necessarily encourage the development of social capital for small-medium cities. This study showed varied associations between density and social capital in small-medium, and large cities, with consistent results regarding land use mix.
长期以来,关于城市形态与社会资本之间关系的讨论一直受到关注,因为它们在文献中得到了很好的记录。然而,关于这两个问题的实证分析仍然有限。本研究以印度尼西亚为例,提出了一种新的视角来研究全球南方城市形态的3Ds(密度、多样性和设计)元素与社会资本之间的联系。利用线性多水平回归,本研究一致揭示了一个矛盾的结果,即较大的居住密度与几个社会资本因素呈负相关。令人惊讶的是,城市中更多的零售区域与一些社会资本指标呈负相关。高连通性并不一定会鼓励中小城市社会资本的发展。该研究表明,在中小城市和大城市中,密度与社会资本之间存在不同的关联,在土地利用组合方面的结果是一致的。

ABSTRACT Based on a case study of Alexandria city, Egypt, this paper investigates the configuration, interrelation, and integration of urban expansion within the framework of sustainability transitions to enhance the performance of sociotechnical transitions. It explores two main arguments; first, to evaluate the recent urban planning innovations, and second, to raise awareness of the participatory planning model to enhance the involvement of the three pillars to better integrate urban sustainable development. It presumes there is a linkage between urban sustainability transitions and the geographical transitions. It further evaluates whether this linkage would benefit accommodating the rapid population growth of Alexandria. This research applies an empirical methodology to test concepts and patterns known from theory generating three scenarios from empirical data. Moving beyond the ‘niche–regime dichotomy’, this study concludes that innovative practices and vested interests are typically constituted in a dualistic manner and tend to incite processes of change in both.
本文以埃及亚历山大市为例,探讨了可持续性转型框架下城市扩张的配置、相互关系和整合,以提高社会技术转型的绩效。它探讨了两个主要论点;首先,评估最近的城市规划创新,其次,提高参与式规划模式的认识,以增强三大支柱的参与,更好地整合城市可持续发展。它假定城市可持续性转型与地理转型之间存在联系。它进一步评估这种联系是否有利于适应亚历山大的快速人口增长。本研究采用实证方法对理论中已知的概念和模式进行检验,从实证数据中生成三种情景。超越“利基制度二分法”,本研究得出结论,创新实践和既得利益通常以二元方式构成,并倾向于激发两者的变化过程。

ABSTRACT We perform a systematic review of the literature on the association between income, employment, and urban poverty from a multidisciplinary perspective. Our results, derived from the analysis of 243 articles, confirm the significant role of employment in the urban poor’s lives, highlighting several factors that constrain their ability to improve their labour market outcomes: lack of access to public transport, geographical segregation, labour informality, among others. Furthermore, the paper finds different strategies used by the poor to promote their inclusion in their city’s economy. We found a major bias towards research focused on advanced economies, stressing the need for development studies dealing with the specific challenges of developing economies.
我们从多学科的角度对收入、就业和城市贫困之间关系的文献进行了系统的回顾。我们通过对243篇文章的分析得出的结果证实了就业在城市贫困人口生活中的重要作用,并强调了几个限制他们改善劳动力市场结果能力的因素:缺乏公共交通工具、地理隔离、劳动力非正式性等。此外,本文还发现了贫困人口促进融入城市经济的不同策略。我们发现主要偏向于关注发达经济体的研究,强调有必要进行处理发展中经济体具体挑战的发展研究。

Using energy justice to contextualise existing challenges of wood charcoal against faecal sludge derived briquettes as a future cooking fuel alternative in Dar Es Salaam, Tanzania 在坦桑尼亚达累斯萨拉姆,利用能源正义来分析木炭与粪便污泥衍生型煤作为未来烹饪燃料替代品的现有挑战

ABSTRACT Over half of the population in Dar es Salaam (DSM), Tanzania, predominately relies on wood charcoal as a cooking fuel, and this is expected to rise to meet future demands. Drawing on the energy justice framework, this article contextualises the current charcoal supply chain of DSM and discusses the possibility of using faecal sludge-derived briquettes (FS briquettes) as a future alternative. This article demonstrates how current injustices in the charcoal supply chain pose challenges related to availability, reliability, affordability and sustainability and concludes that the future energy system of DSM must become more robust and diversified. This article also concludes that while FS briquettes hold the potential to become a viable and energy just cooking fuel alternative, future adoption may be hindered by limited consumer acceptability, inadequate sanitation management and lack of financial investments and government support.
坦桑尼亚达累斯萨拉姆(DSM)超过一半的人口主要依赖木炭作为烹饪燃料,预计这将满足未来的需求。根据能源正义框架,本文将DSM当前的木炭供应链置于背景下,并讨论了使用粪便污泥衍生型煤(FS型煤)作为未来替代方案的可能性。本文展示了当前木炭供应链中的不公正如何对可用性、可靠性、可负担性和可持续性构成挑战,并得出结论,帝斯曼的未来能源系统必须变得更加强大和多样化。本文还得出结论,虽然FS型煤有可能成为一种可行的能源替代燃料,但未来的采用可能会受到消费者接受程度有限、卫生管理不足以及缺乏财政投资和政府支持的阻碍。

The differential impacts of socioeconomic status on vulnerability in urban contexts: a probit analysis of older women in the United States 城市环境中社会经济地位对脆弱性的不同影响:美国老年妇女的概率分析

ABSTRACT This paper integrates a unique dimension of gender in the analysis of economic vulnerability in urban contexts by focusing on women aged 50 and older. We use a probit model to predict the likelihood of vulnerability with a zero-one dummy dependent variable, and four categories of socioeconomic characteristics as predictors: educational attainment, labour market participation, individual demographics, and household characteristics. Using a pooled cross-section of data from the American Community Survey (2013–2017 5-Year estimates), we explore the transmission channel of vulnerability across the four largest cities in the US. The results show, through average marginal effects, a strong association between economic vulnerability and key socioeconomic indicators. The findings support the view that gender differences in labour market participation remain key in explaining disparities. Our two policy prescriptions focus on a more targeted approach in implementing retirement policy changes and loosening the link between labour supply and income.
本文以50岁及以上女性为研究对象,在分析城市经济脆弱性时引入了独特的性别维度。我们使用概率模型来预测脆弱性的可能性,该模型带有一个0 - 1的虚拟因变量,并使用四类社会经济特征作为预测因子:受教育程度、劳动力市场参与、个人人口统计和家庭特征。利用美国社区调查(2013-2017年5年估计)的汇总横截面数据,我们探索了美国四大城市脆弱性的传播渠道。结果表明,通过平均边际效应,经济脆弱性与关键社会经济指标之间存在很强的关联。研究结果支持了这样一种观点,即劳动力市场参与的性别差异仍然是解释差异的关键。我们的两项政策处方侧重于更有针对性地实施退休政策改革和放松劳动力供应与收入之间的联系。

ABSTRACT African urban areas and cities are primarily seen as vulnerable to climate change. Apparent attempts to get required policies have led to the widespread proliferation of overlapping and duplications of policies. Using a policy coherence framework, this study aims to synthesise the coherency of climate adaptation and urban policies in Ghana. The study used content analysis of existing policy documents to understand if specific variables are explicit, implicit or not mentioned in four urban and climate change policies in Ghana. It was found that there is a minimal degree of coherence only in the adaptation measures, but there is a general lack of coherence in the motivation and implementation. This can be attributed to radically different current institutional arrangements for urban planning and climate change, inconsistent use of data and terminologies, and lack of embracement of innovations in urban planning in African cities. The findings suggest that attention must be given to integrated collaborative adaptation planning to address these impediments in urban planning context of African cities.
非洲城市地区和城市主要被视为易受气候变化的影响。显然,试图获得所需的政策导致了政策重叠和重复的广泛扩散。利用政策一致性框架,本研究旨在综合加纳气候适应和城市政策的一致性。该研究对现有政策文件进行了内容分析,以了解加纳的四项城市和气候变化政策中是否明确、隐含或未提及具体变量。研究发现,只有在适应措施方面存在最低程度的一致性,但在动机和实施方面普遍缺乏一致性。这可归因于目前在城市规划和气候变化方面的制度安排截然不同,数据和术语的使用不一致,以及非洲城市在城市规划方面缺乏创新。研究结果表明,必须重视综合协作适应规划,以解决非洲城市规划背景下的这些障碍。
