The critical need for behavioural change for effective solid waste management is well known. However, policies and programmes continue to underemphasize this crucial component in their design, especially in developing countries such as India. Further, empirical research on the psychosocial factors in solid waste management in developing countries is limited, including within India, where a large national programme for solid waste management is currently being implemented. Using a household survey based on the theory of planned behavioural change, we examine the psychosocial factors towards household waste segregation. We find that more than knowledge and attitude, consequences to behaviour play a critical role in intention as well as actual behaviour towards household waste segregation. Based on our findings, we draw implications for redesigning the national programme and contribute to empirical evidence on the role of psychosocial factors in solid waste management in the context of developing countries.
众所周知,迫切需要改变行为,以便有效地管理固体废物。然而,政策和方案在设计中仍然没有充分重视这一关键组成部分,特别是在印度等发展中国家。此外,对发展中国家固体废物管理中的社会心理因素的实证研究有限,包括在印度,印度目前正在实施一项大型国家固体废物管理方案。利用一项基于计划行为改变理论的家庭调查,我们考察了家庭垃圾分类的心理社会因素。我们发现,除了知识和态度之外,行为后果在家庭垃圾分类的意图和实际行为中发挥着关键作用。根据我们的研究结果,我们得出了重新设计国家方案的启示,并为发展中国家固体废物管理中社会心理因素的作用提供了经验证据。

This article introduces the concept of ‘Sea Cities’ to emphasize a range of tactics to acknowledge the relationship between the sea and cities. This concept is critical for the possibility of integrating future aquatic-based urbanism to address climate change, and in particular, the issue of rising sea levels, which is currently faced by the majority of coastal cities. We compare and assess the tactics of four sea cities (i.e., to fortify, accommodate, release, and floating) against the case study of Jakarta. Jakarta is deemed to be among the metropolitan cities most vulnerable to sea level rise, owing to overpopulation alongside the fact that its land is sinking rapidly due to massive urban development. In order to understand the prospects and pitfalls of each tactic for Jakarta, we analyse scholarly literature on the subject, official government reports and documents, as well as policy briefs released by governments at the national level. This study finds that massive hard structural solutions are not only insufficient but also ineffective towards solving the challenges of climate change in Jakarta, especially the rising sea level. At the same time, it also identifies that while the combination of accommodating and floating tactics has never been considered as future a planning option, this could enable more resilient and adaptive solutions for the future development trajectory of Jakarta. In doing so, it could also provide important transferrable lessons for other coastal cities, especially those within developing countries.
本文介绍了“海洋城市”的概念,强调了一系列认识海洋与城市关系的策略。这一概念对于整合未来以水生为基础的城市主义以应对气候变化,特别是大多数沿海城市目前面临的海平面上升问题的可能性至关重要。我们以雅加达为例,对四个海上城市的策略(即设防、容纳、释放和漂浮)进行了比较和评估。雅加达被认为是最容易受到海平面上升影响的大城市之一,因为人口过剩,而且由于大规模的城市发展,它的土地正在迅速下沉。为了了解雅加达每一种策略的前景和陷阱,我们分析了有关该主题的学术文献、官方政府报告和文件,以及各国政府在国家层面发布的政策简报。本研究发现,大规模的硬结构解决方案不仅不足,而且对解决雅加达气候变化的挑战,特别是海平面上升的挑战无效。与此同时,它也表明,虽然通融和浮动策略的结合从未被视为未来的规划选择,但这可以为雅加达未来的发展轨迹提供更具弹性和适应性的解决方案。在这样做的过程中,它也可以为其他沿海城市,特别是发展中国家的沿海城市提供重要的可转移的经验教训。

Methodological Dimensions of Delineating Peri-urban Areas: The Case of Kolkata Metropolis 边缘城市区域划分的方法论维度——以加尔各答大都市为例
IF 1.3 Q4 ENVIRONMENTAL STUDIES Pub Date : 2020-08-23 DOI: 10.1177/0975425320938519
Dinabandhu Mondal, S. Sen
In the past few decades, due to urbanization and spatial expansion of cities beyond their municipal boundaries, complex interactions between the city and its surrounding rural areas have occurred, resulting in the formation of peri-urban spaces or zones of transition. There is a plurality of definitions for these peri-urban spaces, due to their diverse character in terms of land and water use, livelihood shifts, demographic and social transitions. Most peri-urban areas, specifically those around large metropolitan cities, are increasingly assuming complex characters, which call for governance structures beyond rural–urban binaries. For any administrative intervention of a serious nature in peri-urban areas, a standard methodology for demarcation of these spaces is required. This article is an attempt to develop and apply such a methodology beyond the existing ones, using government sources of data, in the case of Kolkata Metropolis. This article uses socio-economic and land-use characteristics to achieve this objective. It finds that peri-urban spaces do not necessarily develop uniformly around the city; instead, they are fragmented and could be located both near or relatively far from urban areas.
在过去的几十年里,由于城市化和城市在城市边界之外的空间扩张,城市与其周围农村地区之间发生了复杂的互动,导致了城市周边空间或过渡区的形成。由于这些城市周边空间在土地和水资源利用、生计转变、人口和社会转型方面的多样性,因此有多种定义。大多数城市周边地区,特别是大城市周围的地区,越来越呈现出复杂的特征,这需要超越农村-城市二元体系的治理结构。对于城市周边地区的任何严重行政干预,都需要制定这些空间的标准划分方法。本文试图在现有方法的基础上,利用政府的数据来源,以加尔各答大都会为例,开发和应用这种方法。本文利用社会经济和土地利用的特点来实现这一目标。研究发现,城市周边空间不一定在城市周围统一发展;相反,它们是分散的,可能位于城市附近,也可能相对远离城市。

Slum Rehabilitation Through Public Housing Schemes in India: A Case of Chandigarh 印度通过公共住房计划改造贫民窟:以昌迪加尔为例
IF 1.3 Q4 ENVIRONMENTAL STUDIES Pub Date : 2020-08-23 DOI: 10.1177/0975425320938536

It is a widely accepted fact that sustainable development cannot be achieved without sustainable human settlements. Cities cannot be made sustainable without ensuring access to adequate and affordable housing to all and improving informal settlements. According to the Census of India (2011), 13.75 million urban households, that is, 65–70 million people live in informal settlements and about 1.77 million people were homeless in India. The goal of sustainable cities cannot be fulfilled with such a large number of populations still being deprived of their basic right to adequate housing. Chandigarh is one of the first planned cities of modern India and has the second highest percentage (89.8%) of urban population to its total population among all the states and union territories in India. This article endeavours to analyse the adequacy and affordability of public housing for urban poor in the Union Territory of Chandigarh.
没有可持续的人类住区就不能实现可持续发展,这是一个普遍接受的事实。如果不确保所有人都能获得适当和负担得起的住房,并改善非正式住区,城市就无法实现可持续发展。根据印度人口普查(2011),印度有1375万城市家庭,即6500万至7000万人居住在非正式定居点,约有177万人无家可归。在如此大量的人口仍然被剥夺获得适当住房的基本权利的情况下,可持续城市的目标是无法实现的。昌迪加尔是现代印度最早规划的城市之一,在印度所有州和联邦领土中,城市人口占总人口的比例第二高(89.8%)。本文试图分析昌迪加尔联邦领土城市贫民公共住房的充分性和可负担性。

This article examines ‘green products’ as a means of expressing ‘green behaviour’ in an emerging economy. The empirical evidence focused on green awareness, behaviour and green culture as a contributing factor. A self-administered questionnaire was run to collect data from consumers (n = 280) approximately 93 per cent of urbanite in Kuala Lumpur, Malaysia. SmartPLS3.0 was used to analyse the measurement and structural model assessment. Findings suggest that attitude and the green culture had a higher influence on green behaviour. However, the evaluation of green behaviour is not dependent on economic development. Perceived behavioural control (PBC) was found to be insignificant among Malaysian citizens. In particular, awareness interaction between behaviour and culture were insignificant, not sufficient to predict behaviour. The study suggested it is important to educate Malaysian citizens from grassroots about the significance of environmental education and put forward actions to improve green behaviour status and promote green marketing.

Generally, it is assumed that the poor in cities cannot afford to own a house. Thus, real estate developers hardly consider them as potential buyers. Despite the fact that the government has framed favourable policies towards housing the poor, the poor cannot own houses due to the inadequacy of institutional supports. This study examines the affordability of owned or rental accommodation for the poor, taking ready-made garment (RMG) workers in Dhaka as a case in point. Data from across 138 households have been gathered for this study. The study shows that if the rent increases further than the minimum standard for a dwelling unit, then about half of the RMG households become unable to afford their rental houses. An analysis of home ownership shows that only 28 per cent of families can buy a house of 300 sq. ft. on the basis of existing loan structures, and only if the loan covers the total property value, particularly at the periphery of the city area. If the loan structure for housing finance is changed by lowering the interest rate and increasing the loan repayment period, then more workers would be able to afford to own a small house of moderate standard.
一般来说,人们认为城市里的穷人买不起房子。因此,房地产开发商几乎不认为他们是潜在买家。尽管政府制定了为穷人提供住房的有利政策,但由于体制支持不足,穷人无法拥有住房。这项研究以达卡的现成服装工人为例,考察了穷人拥有或租赁住房的可负担性。本研究收集了来自138个家庭的数据。研究表明,如果租金上涨幅度超过住宅单元的最低标准,那么大约一半的RMG家庭将无法负担租房费用。一项对房屋所有权的分析显示,只有28%的家庭能够在现有贷款结构的基础上购买300平方英尺的房子,而且前提是贷款覆盖了房地产的总价值,尤其是在城市边缘地区。如果通过降低利率和延长贷款偿还期来改变住房金融的贷款结构,那么更多的工人将能够拥有一套中等标准的小房子。

Neoliberal Urbanity and the Right to Housing of the Urban Poor in Dhaka, Bangladesh 新自由主义都市化与孟加拉达卡城市贫民的住房权
IF 1.3 Q4 ENVIRONMENTAL STUDIES Pub Date : 2020-08-19 DOI: 10.1177/0975425320938520

In Dhaka, the capital city of Bangladesh with a population of 18 million, nearly one-third are living under the threat of eviction without resettlement due to lack of tenure security. This occurs despite the Bangladesh government’s ratification of multiple international conventions as well as provisions within the national Constitution with regard to people’s rights. Within this context, drawing on Lefebvre’s theorization of space and using the right to the city (RTC) framework, this article explores the urban poor’s right to housing in the context of Dhaka, Bangladesh. Findings suggest that the local and central government officials categorize slum dwellers as encroachers and criminals, who pose a direct threat to an orderly, clean and green city. Hence, they cannot be allowed to exist in the city. Additionally, the state has shifted the development of land and housing markets to real estate developers, following a neoliberal economic model. Consequently, a few powerful developers control Dhaka’s land and housing markets, only supplying housing for the growing middle class. Access to these houses is far beyond poor people’s reach. Thus, the urban poor’s housing rights are denied both by the state and by the market in Dhaka.
在拥有1800万人口的孟加拉国首都达卡,由于缺乏保有权保障,近三分之一的人生活在被驱逐而没有重新安置的威胁之下。尽管孟加拉国政府批准了多项国际公约以及国家宪法中关于人民权利的条款,但这种情况仍然存在。在此背景下,本文借鉴列斐伏尔的空间理论,运用城市权框架,探讨了孟加拉国达卡背景下城市穷人的住房权问题。调查结果表明,地方和中央政府官员将贫民窟居民归类为侵占者和罪犯,他们对一个有序、清洁和绿色的城市构成直接威胁。因此,不能允许他们在城市中存在。此外,该州遵循新自由主义经济模式,将土地和住房市场的开发转向了房地产开发商。因此,少数强大的开发商控制着达卡的土地和住房市场,只为日益壮大的中产阶级提供住房。穷人根本无法进入这些房子。因此,达卡的国家和市场都剥夺了城市穷人的住房权。

Rapid urbanisation has always been considered a determinant of the changing urban ecology, which encompasses vegetation, open spaces and vacant land to a compact urban area. Such changes of urban ecology expose coastal cities and make them vulnerable to natural disasters like flash floods and storm surges. This study uses the Compound Annual Growth Rate model and geospatial analysis to assess the changes to the urban ecology along the 43 km long coastline of Muscat, one of the fastest growing highly urbanized coastal capitals of the Arab world. The changes are calculated on 5 m and 10 m datums for three time periods (1990s, 2010s and 2017 onwards). The study finds that since the 2010s both the agricultural and low land have changed to a compact urban built-up area; highly dense vegetation and open spaces changed to scattered ornamental plantation and impervious areas. Such changes to the urban ecology along the coastline increase the vulnerability of Muscat to both sudden and slow onset of natural disasters. A critical literature analysis was also conducted to understand the changes to the urban ecology due to urbanization of global coastal cities in comparison to Muscat. With the quantitative data from the growth model and qualitative approach from critical literature analysis, this article finds that urban resilience for the Muscat coastline has been compromised due to changes in the urban ecology.
快速的城市化一直被认为是城市生态变化的决定因素,城市生态包括植被、空地和紧凑的城市区域。城市生态的这种变化暴露了沿海城市,使它们容易受到山洪和风暴潮等自然灾害的影响。这项研究使用复合年增长率模型和地理空间分析来评估马斯喀特43公里长海岸线沿线的城市生态变化,马斯喀特是阿拉伯世界增长最快的高度城市化的沿海首都之一。这些变化是在三个时间段(20世纪90年代、2010年代和2017年以后)的5米和10米基准上计算的。研究发现,自2010年代以来,农业和低地都已转变为紧凑的城市建成区;高度茂密的植被和空地变成了分散的观赏性种植园和防渗区。海岸线城市生态的这种变化增加了马斯喀特对突然和缓慢发生的自然灾害的脆弱性。还进行了批判性文献分析,以了解与马斯喀特相比,全球沿海城市由于城市化而对城市生态的变化。利用增长模型的定量数据和批判性文献分析的定性方法,本文发现,由于城市生态的变化,马斯喀特海岸线的城市韧性受到了损害。

Housing ideally supplies many physical comforts, social and economic benefits, as well as forms the basis for the right to the city. It also addresses an additional challenge of adaptation to the current as well as expected impacts of climate change—one of them being heat waves—especially in the context of developing countries like India. Few studies in the Indian context have explicitly examined the experience of heat on the indoor temperatures linked to the housing quality and typologies and the quality of the surroundings. Official state and urban policies do not explicitly include heatproofing for existing or new housing to address indoor heat exposure, especially in the case of vulnerable populations. We have measured the indoor and outdoor temperatures in 860 low-income residents living in three different housing typologies in 26 settlements (formal and informal) of Ahmedabad, India, in peak summer months. Building the case for a long-term urban housing strategy to address the impact of indoor temperature particularly for low-income households and residents of informal housing, we argue that conscious and deliberate efforts towards heatproofing existing informal housing are required. One of the options, which is being pursued currently, is transiting informal housing dwellers to formal housing. But, another one for immediate consideration is renewal of current informal housing due to limited coverage possibility of the first option.
住房理想地提供了许多物质享受、社会和经济利益,并构成了城市权利的基础。它还解决了适应气候变化当前和预期影响的额外挑战,其中之一是热浪,尤其是在印度等发展中国家的情况下。在印度背景下,很少有研究明确研究与住房质量、类型和周围环境质量相关的室内温度对热量的影响。官方的州和城市政策没有明确包括现有或新住房的隔热,以解决室内高温暴露问题,尤其是在弱势群体的情况下。我们测量了860名低收入居民的室内和室外温度,他们居住在印度艾哈迈达巴德26个定居点(正式和非正式)的三种不同的住房类型中,在夏季高峰期。为制定长期的城市住房战略,以解决室内温度的影响,特别是对低收入家庭和非正规住房居民的影响,我们认为,需要有意识和深思熟虑地努力为现有的非正规住房隔热。目前正在寻求的选择之一是将非正规住房居民转变为正规住房。但是,另一个需要立即考虑的问题是,由于第一种选择的覆盖可能性有限,目前的非正规住房需要更新。
