ABSTRACT The removal of excreta or faecal sludge from full pit latrines – pit emptying – is essential to extend the life of the sanitation technology, especially for the millions of users living in the dense, urban areas of the Global South. Unfortunately, pit-emptying is rarely practiced due to factors related to accessibility, disgust, and importantly, cost. We examined the impact of two different types of vouchers distributed in Blantyre, Malawi, to understand if and how subsidies could increase the practice of pit emptying in low-income areas. We found that pit emptying businesses were able to game the system to charge more money on top of the discount in the first study in which 21% vouchers were redeemed from 252 distributed. In a follow-up study, 25% vouchers were redeemed from 400 distributed with more rigorous subsidy targeting and structuring. We discuss why complex drivers for subsidy adoption among low-income households require further research.
从全坑厕所中清除排泄物或粪便污泥-排空坑-对于延长卫生技术的使用寿命至关重要,特别是对于生活在全球南方人口稠密的城市地区的数百万用户。不幸的是,由于易接近性、厌恶和重要的成本等因素,排空坑很少被实践。我们研究了在马拉维布兰太尔分发的两种不同类型的代金券的影响,以了解补贴是否以及如何增加低收入地区的排空坑的做法。我们发现,在第一项研究中,排空坑的企业能够在折扣的基础上利用系统收取更多的钱,其中有21%的代金券被赎回。在一项后续研究中,发放了400张更严格的补贴目标和结构的代金券,其中25%被赎回。我们讨论了为什么低收入家庭采用补贴的复杂驱动因素需要进一步研究。

ABSTRACT Planned after the City Beautiful Movement and Garden City Movement, Manila City and Quezon City, now among Metro Manila’s 16 cities, did not result in the desired outcomes of their planners. The history of unfulfilled visions that began with Burnham’s 1905 Plan for Manila repeated in similar fashion in Quezon City in its 1949 Frost-Arellano Plan. How do Metro Manila’s public green spaces, as remnants of these plans, sustained specific visions for meeting human needs? To find answers, we focused on Rizal Park and the University of the Philippines (UP) Academic Oval – two public green spaces that remained from the Burnham and Frost-Arellano plans. Contemporary uses of these spaces suggest that the intermingling of the upper and lower classes as envisioned in these plans is limited; nonetheless, they represent endeavours by fairly diverse groups to actively satisfy human needs within and beyond how these spaces were initially designed.
在城市美丽运动和花园城市运动之后,马尼拉市和奎松市,现在马尼拉大都会的16个城市,并没有得到他们的规划者期望的结果。从伯纳姆1905年的马尼拉计划开始,未能实现的愿景的历史在奎松市以类似的方式重复了1949年的弗罗斯特-阿雷拉诺计划。作为这些计划的残余,马尼拉大都会的公共绿色空间如何维持满足人类需求的具体愿景?为了找到答案,我们专注于Rizal公园和菲律宾大学(UP)学术椭圆——两个公共绿色空间,从Burnham和Frost-Arellano计划中保留下来。这些空间的当代使用表明,这些计划中所设想的上层和下层阶级的混合是有限的;尽管如此,它们代表了相当多样化的群体在最初设计空间内外积极满足人类需求的努力。

ABSTRACT Biking contributes to a better environment by reducing short car trips and improving public health. The street-scale built environment affects the appeal of streets to cyclists, and thus influences route choice behaviour. This study develops a stated choice experiment that systematically varies eight attributes of the built environment to examine preference structure differences pertaining to the street-scale built environment among cyclists in the context of access/egress trip to a metro station. The environment is systematically varied in terms of road length, average number of building floors, retail frontage, cycling facilities at intersections, bike lane width, greenery, lamp density, and crowdedness. Eight hundred and three respondents completed the choice task using face to face interviews in Tianjin, China. Results suggest the existence of two latent classes of cyclists that differ in their preference for the street-scale built environment.
骑自行车减少了短途汽车旅行,改善了公共健康,有助于改善环境。街道尺度的建筑环境影响街道对骑自行车者的吸引力,从而影响路线选择行为。本研究开发了一个陈述选择实验,系统地改变了建筑环境的八个属性,以检验在地铁站进出的背景下,骑自行车的人在街道规模的建筑环境中的偏好结构差异。环境在道路长度、平均建筑楼层数、零售临街、十字路口的自行车设施、自行车道宽度、绿化、灯密度和拥挤程度等方面都有系统的变化。在中国天津,883名受访者通过面对面访谈完成了选择任务。结果表明,存在两类潜在的骑自行车者,他们对街道规模的建成环境的偏好不同。

E-scooters: competition with shared bicycles and relationship to public transport 电动滑板车:与共享单车的竞争以及与公共交通的关系

ABSTRACT E-scooters have recently emerged as an alternative means of transportation in cities. It remains unclear whether e-scooters compete for users with bicycles – another mode of shared micromobility. Their relationship to public transport can be complementary or substitutionary, and it has not been ascertained which effect prevails. This paper contributes to answering these questions using empirical trip-level data on Warsaw. We find that there is little difference between e-scooters’ and bicycles’ speed and that placement of bicycle docks influences number of e-scooter trips, which is an indication that they compete for the same market. E-scooters’ trip data shows that they are more complementary to rapid public transport and may contribute to solving the last-mile problem. We discuss the importance of results for optimal policy promoting environmentally friendly transportation and identify further research directions.
电动滑板车最近成为城市中另一种交通工具。目前尚不清楚电动滑板车是否会与另一种共享微型交通方式——自行车争夺用户。它们与公共交通的关系可以是互补的,也可以是替代的,目前还没有确定哪种影响更大。本文利用华沙的经验旅行水平数据来回答这些问题。我们发现电动滑板车和自行车的速度差异不大,并且自行车码头的位置影响电动滑板车的出行次数,这表明它们在竞争同一市场。电动滑板车的出行数据显示,它们与快速公共交通更具互补性,可能有助于解决最后一英里问题。我们讨论了结果对于促进环境友好型交通的最优政策的重要性,并确定了进一步的研究方向。

ABSTRACT A dual land administration system in Ghana necessitates the adoption of hybrid and locally adaptive planning practices. However, whilst the scholarly discourse on hybrid planning is burgeoning, its implications for sustainable urban development are limited. Using qualitative case studies of data collected from interviews and focus group discussions with key stakeholders in Tamale and Techiman, this paper highlights the implications of hybrid planning for sustainable urban development. Although in tune with current proposals for collaborative land use planning, hybrid planning practices in peri-urban areas are dominated by land-owning chiefs who finance land use planning activities, leading to a negotiated planning and land delivery system. This engenders urban sustainability challenges, including tenure insecurities, land speculation and urban sprawl and hinders the realisation of the Sustainable Development Goal 11. Thus, urban planners must re-examine current planning practices and leverage the New Urban Agenda to explore innovative ways of ensuring sustainable urban expansion.
加纳的双重土地管理制度要求采用混合的和适合当地的规划实践。然而,虽然混合规划的学术论述正在蓬勃发展,但其对可持续城市发展的影响有限。本文通过对塔梅尔和特希曼主要利益相关者的访谈和焦点小组讨论中收集的数据进行定性案例研究,强调了混合规划对可持续城市发展的影响。虽然与目前的协同土地利用规划建议一致,但城郊地区的混合规划实践由土地所有者酋长主导,他们为土地利用规划活动提供资金,导致协商规划和土地交付系统。这给城市可持续性带来了挑战,包括权属不安全、土地投机和城市扩张,并阻碍了可持续发展目标11的实现。因此,城市规划者必须重新审视当前的规划实践,并利用《新城市议程》探索确保可持续城市扩张的创新方式。

Slum Upgrading beyond incubation: exploring the dilemmas of nation-wide large scale policy interventions in Brazil´s growth acceleration programme (PAC) 超越孵化的贫民窟改造:探索巴西增长加速计划(PAC)中全国性大规模政策干预的困境

Slum upgrading policies and practices have continued to interest both scholars and practitioners. The 2007 launch of the Brazilian Growth Acceleration Program (PAC) has added a new dimension to the debate. The latter represented an ambitious program of interventions, regulation and finance that articulated states and municipalities at national level around the development of local slum upgrading programmes, with a scope and scale that had never been achieved before in the country. Our main objective here is not to review the relative extensive and growing literature on slum upgrading in the Global South. Nevertheless, a few observations are in place to both situate our empirical analysis regarding the impact of PAC within the broader discussions on slum upgrading, as well as to argue how this paper contributes to the existing work in the field. A first strand of research has emphasised the evolution of national slum upgrading policies, often illustrated with the analysis of specific upgrading experiences in emblematic cities to reinforce the overall argument. This historical approach has stressed how initial slum clearance and removal has given place to ‘non-conventional’ strategies such as incremental housing, aided self-help, sites and services and the rolling out of upgrading programs. A number of authors have also claimed the more recent hollowing out of these ‘alternative’ approaches and the comeback of ‘conventional’ housing strategies through the provision of social market housing, or the emergence of urban entrepreneurialism through large urban redevelopment projects (Wakely 2015; Lindert, 2015; Dupont et al. 2016). This strand of work frequently combines broader historical research on tendencies of donors and national governments with paradigmatic upgrading experiences in specific flagship cities (Imparato and Ruster 2003; Burra 2005; Magalhâes 2016). Dupont et al. (2016), for example, analyse Rio de Janeiro, Delhi, Chennai, Durban, Cape Town and Lima in order to flesh out the mismatches between the design and implementation of upgrading and its subsequent undermining through urban neoliberalisation in Brazil, India, South Africa and Peru. Likewise, Ren (2017) combines detailed case studies in Rio, Bombay and Ghuangzhou in order to analyse how the inherent tensions between entrepreneurial urban governance and slum upgrading strategies are being played out in these countries. Along the same lines, Werlin (1999) provides an extensive overview of large-scale upgrading experiences in Calcutta, Jakarta and Manilla and argues that the ‘minimal state’ approach that was implicitly advocated by John Turner is unlikely to succeed in up-scaling policies in these countries (and the Global South as such) if issues such as land tenure, the finance-cost-recovery nexus and participation in the design, implementation and maintenance of projects are not taken into consideration. A second strand in the upgrading literature is focussed on detailed, sometime
贫民窟改造政策和实践一直引起学者和实践者的兴趣。2007年启动的巴西增长加速计划(PAC)为这场辩论增加了一个新的维度。后者是一项雄心勃勃的干预、监管和融资方案,将各州和市政当局在国家一级围绕当地贫民窟改造方案的发展联系起来,其范围和规模在该国是前所未有的。我们在这里的主要目的不是审查关于全球南方贫民窟改造的相对广泛和不断增长的文献。尽管如此,本文还是提出了一些意见,以便将我们对PAC影响的实证分析置于有关贫民窟改造的更广泛讨论中,并说明本文如何有助于该领域的现有工作。第一部分研究强调了国家贫民窟改造政策的演变,通常通过分析具有象征意义的城市的具体改造经验来说明,以加强整体论点。这种历史性的做法强调了最初的贫民窟清理和搬迁如何让位于“非常规”战略,如增加住房、援助自助、场地和服务以及推出升级计划。许多作者还声称,最近这些“替代”方法的空心化和“传统”住房战略的回归,通过提供社会市场住房,或者通过大型城市重建项目出现城市企业家精神(Wakely 2015;兰德博士,2015;Dupont et al. 2016)。这一系列工作经常将捐助者和国家政府倾向的更广泛的历史研究与特定旗舰城市的范例升级经验结合起来(Imparato和Ruster 2003;巴拉2005;Magalhaes 2016)。例如,杜邦等人(2016)分析了里约热内卢、德里、金奈、德班、开普敦和利马,以充实巴西、印度、南非和秘鲁的城市新自由主义化的设计和实施与随后的破坏之间的不匹配。同样,Ren(2017)结合了里约、孟买和广州的详细案例研究,以分析企业家城市治理和贫民窟改造战略之间的内在紧张关系在这些国家是如何发挥作用的。沿着同样的思路,Werlin(1999)对加尔各答、雅加达和马尼拉的大规模升级经验进行了广泛的概述,并认为如果不考虑土地保有权、财政-成本回收关系以及参与项目的设计、实施和维护等问题,约翰·特纳(John Turner)隐含提倡的“最小国家”方法不太可能在这些国家(以及全球南方国家)的大规模政策中取得成功。改造文献的第二部分侧重于对贫民窟改造的局限性和潜力进行详细的、有时是比较的案例研究

Bringing the Global to the Local: the challenges of multi-level governance for global policy implementation in Africa 将全球带到地方:非洲实施全球政策的多层次治理的挑战

ABSTRACT The New Urban Agenda (NUA) and Agenda 2030’s Sustainable Development Goals (SDGs) recognise the key role of ‘sub-national entities’, including cities, in achieving sustainable development. However, since these global policy agendas were agreed and signed by national governments, implementing them at the local level requires a process of localisation to fit local realities. This paper analyses the national guidance (or lack of) and the resultant collaborations emerging between various levels of government in the implementation of these agendas in African cities, namely Kisumu, Kenya and Cape Town, South Africa. It argues that effective implementation of the SDGs requires a strong framework for multi-stakeholder engagement and coordination at all levels of governance, which is possible if both top-down and bottom-up approaches are used concurrently and harmonised.
《新城市议程》(NUA)和2030年可持续发展目标(sdg)认识到包括城市在内的“地方实体”在实现可持续发展方面的关键作用。然而,由于这些全球政策议程是由各国政府同意并签署的,因此在地方一级实施这些议程需要一个适应当地实际情况的本地化过程。本文分析了在非洲城市(即肯尼亚基苏木和南非开普敦)实施这些议程时,国家指导(或缺乏指导)以及各级政府之间由此产生的合作。报告认为,可持续发展目标的有效实施需要一个强有力的框架,以便在各级治理中多利益攸关方参与和协调,如果自上而下和自下而上的方法同时使用并协调一致,这是可能的。

ABSTRACT What are patterns, outcomes, and factors emerging from the urban environmental sustainability actions? To what extent do the conditions of action arenas facilitate urban environmental actions? In this research, the community-level public space named ‘neighbourhood activity centres’ in Taipei City is observed and investigated. Besides the field observation effort, a data set is established with the combination of subjective and objective data sources collected from a questionnaire investigation (255 units of observations) and the governmental open data systems. After employing ordinary least squares (OLS) regression analysis, the author concludes that environmental friendly facilities (such as aquaponics systems), environmental tendency of the communities, exhibition of policies or regulations and action networks among participants, could facilitate the outcomes of urban environmental sustainability movement. However, the diversity among the participants negatively affects the relationships between some external factors and action outcomes. The divergence in actor preference increases the required transaction costs in the consensus process due to time-consuming communication and compromise. This study thus proposes recommendations, such as benchmark Lis and neighbourhood associations, as policy application that could enhance municipal implementation of sustainability policies.
城市环境可持续性行动的模式、结果和因素是什么?行动场所的条件在多大程度上促进了城市环境行动?本研究以台北市的“邻里活动中心”为研究对象,对其社区层面的公共空间进行观察与调查。除了实地观测工作外,还将从问卷调查(255个观测单位)和政府开放数据系统收集的主观和客观数据源相结合,建立了一个数据集。采用普通最小二乘(OLS)回归分析,认为环境友好型设施(如鱼菜共生系统)、社区的环境倾向、政策法规的展示和参与者之间的行动网络对城市环境可持续性运动的结果有促进作用。然而,参与者的多样性对某些外部因素与行动结果之间的关系产生了负面影响。行动者偏好的差异增加了共识过程中所需的交易成本,这是由于费时的沟通和妥协。因此,本研究提出了一些建议,如建立基准Lis和社区协会,作为政策应用,可以加强城市可持续发展政策的实施。

‘Resettlement with Chinese characteristics’: the distinctive political-economic context, (in)voluntary urbanites, and three types of mismatch “有中国特色的移民安置”:独特的政治经济背景、自愿的城市居民和三种类型的错配

ABSTRACT In recent years, urban resettlement as a specific form of urbanisation has gained its momentum in planning practices to accommodate newcomers of cities, in line with the macro policy reforms of urban-rural integration. This paper synthesises literature related to the proposed term ‘urban resettlement with Chinese characteristics’ to shed light on the distinctive and unparalleled socio-economic and spatial transformation entailed by the ongoing urban resettlement in China. Mindful of China’s socialist ideology and authoritarian regime, we argue that urban resettlement has become a potent tool for the Chinese government to fuel economic development and urbanisation. The longstanding issues such as involuntary resettlement have been alleviated with the gradualist institutional changes, but emerging predicaments concerning social mismatch, space mismatch, and spatial mismatch still linger. This paper calls for researchers to draw lessons and implications from the discourse of ‘urban resettlement with Chinese characteristics’ to expand the knowledge of sustainable urban-rural development.
近年来,随着城乡一体化的宏观政策改革,城市移民作为城市化的一种特殊形式,在城市新移民安置的规划实践中获得了发展势头。本文综合了与“中国特色城市移民安置”相关的文献,以揭示中国正在进行的城市移民安置所带来的独特和无与伦比的社会经济和空间转变。考虑到中国的社会主义意识形态和专制政权,我们认为城市安置已成为中国政府推动经济发展和城市化的有力工具。随着渐进式制度变迁,非自愿移民等长期存在的问题得到了缓解,但社会错配、空间错配、空间错配等新问题依然存在。本文呼吁研究者从“中国特色城市移民安置”的话语中汲取教训和启示,拓展对城乡可持续发展的认识。

ABSTRACT This study explores residents’ choice to migrate from the city core to stay in close neighbourhoods, with the main objective to evaluate peoples’ preferences. Find out the degree of influence of factors like gender, income, age, years of stay, family composition, ethnicity, and house ownership in determining the choice of stay. An interview and questionnaire were used to elicit information from household heads. The multinomial regression method was applied to test the hypothesis that, ‘there is no significant relationship between choice of stay in neighbourhoods and given factors’. The study revealed that gender, income, years of stay and ethnicity have a negative contribution to the choice of stay, while age, family composition and house ownership have a positive influence. Hence, it is recommended that for sustainability, factors that increase densification to reduce mobility should be encouraged.
摘要本研究探讨了居民从城市核心迁移到附近社区的选择,主要目的是评估人们的偏好。找出性别、收入、年龄、居住年限、家庭组成、种族、房屋所有权等因素对选择居住的影响程度。采用访谈和问卷调查的方式从户主处获取信息。多项回归方法被用来检验假设,“在选择留在社区和给定因素之间没有显著的关系”。研究表明,性别、收入、居住年限和种族对居住选择有消极影响,而年龄、家庭组成和房屋所有权有积极影响。因此,建议为了可持续性,应鼓励增加密度以减少流动性的因素。
