Urban flooding is growing as a serious development challenge for cities. Urbanization demands the conversion of pervious land to impervious land by pushing the transformation of water bodies, flood plains, wetlands and green spaces into built-up spaces. This affects the hydrological setting of the city’s geographic area. Bhubaneswar, one of the first planned cities of independent India, has expanded rapidly with an increase in the settlement land use cover from 41 km2 to 81 km2 in the last two decades. Non-consideration of disaster risk assessment in the land use plan has placed the city at high disaster risk. Hence, this article explores various avenues for making a flood resilient city through spatial planning. To understand the flood and its consequences, a flood hazard and vulnerability map was prepared by overlaying the existing social and infrastructure networks, and flood risk zones were generated through analytical spatial modelling in GIS. This accounts for the areas in which flood hazards are expected to occur, as well as the area whose socio-economic and infrastructure susceptibility to the disaster is more. The key outcome is to ensure urban development that can work concurrently with nature by integrating disaster risk reduction strategies into land use planning.
城市洪水日益成为城市发展面临的严峻挑战。城市化要求通过推动水体、洪泛区、湿地和绿地向建成区的转变,将透水土地转变为不透水土地。这会影响城市地理区域的水文环境。布巴内斯瓦尔是印度独立后最早规划的城市之一,在过去20年中,随着定居点土地使用面积从41平方公里增加到81平方公里,该城市迅速扩张。土地利用规划未考虑灾害风险评估,使该市处于高灾害风险之中。因此,本文探索了通过空间规划打造抗洪城市的各种途径。为了了解洪水及其后果,通过覆盖现有的社会和基础设施网络编制了洪水危害和脆弱性地图,并通过GIS中的分析空间建模生成了洪水风险区。这说明了预计会发生洪水灾害的地区,以及社会经济和基础设施更容易受到灾害影响的地区。关键成果是通过将减少灾害风险战略纳入土地利用规划,确保城市发展能够与自然同步进行。

There has been a growing interest in the impact of environmental awareness on ‘green’ or ‘environmentally friendly’ consumption patterns, and this has been the subject of much research by environmental psychologists. However, the effect of environmental awareness on residents and their attachment to their homes and their environment has received little attention and is worthy of closer examination. Outdoor air quality can be considered one of the most critical environmental factors impacting the value of a residential location. This research investigates how air pollution-related environmental factors influence residents’ attachment to the place of residence and their willingness to move. It defines the structural relationship between air pollution awareness parameters, which are later employed in the proposed structural equation model (SEM), to explain ‘district loyalty’. A survey was carried out in Almaty, Kazakhstan, one of the most populated and polluted cities in Central Asia. A total of 550 respondents responded. Based on the overall model’s test results, the factors relating to district loyalty explained the 17.5% variation in the samples, which suggests that the perception of residents to their district air quality has a low-level impact on loyalty to their place of residence. The power of perceived environmental risks appears to have little relation to district loyalty. The most influential factor on the model is environmental behaviour parameter, which is about adopting attitudes and behaviours aimed at minimizing negative impacts on the environment. When the perceived environmental risk increased, their place attachment levels only slightly decreased. However, the obtained results do not confirm that district loyalty significantly correlates with their readiness/unreadiness to move to another residence in order to enjoy improved air quality. To sum up, environmental awareness of local air quality seems not to directly affect residents’ attachment to place. Nevertheless, indirect effects can be presented in research relating to urban residents’ place attachment. Research, policy and sectoral implications of the findings are addressed and discussed in detail.
人们对环境意识对“绿色”或“环保”消费模式的影响越来越感兴趣,这也是环境心理学家进行大量研究的主题。然而,环境意识对居民及其对家园和环境的依恋的影响却很少受到关注,值得进一步研究。室外空气质量可以被认为是影响住宅位置价值的最关键的环境因素之一。本研究探讨空气污染相关环境因素如何影响居民对居住地的依恋和迁移意愿。它定义了空气污染意识参数之间的结构关系,这些参数后来被用于提出的结构方程模型(SEM),以解释“地区忠诚度”。一项调查是在哈萨克斯坦的阿拉木图进行的,这是中亚人口最多、污染最严重的城市之一。共有550名受访者做出了回应。根据整体模型的测试结果,与地区忠诚度相关的因素解释了样本中17.5%的变化,这表明居民对其所在地区空气质量的感知对其居住地忠诚度的影响程度较低。环境风险感知能力与地区忠诚度关系不大。对模型影响最大的因素是环境行为参数,它是关于采取旨在尽量减少对环境的负面影响的态度和行为。当感知环境风险增加时,他们的地方依恋水平仅略有下降。然而,所获得的结果并没有证实地区忠诚度与他们是否愿意为了享受改善的空气质量而搬到另一个住所显著相关。综上所述,当地空气质量的环保意识似乎并不直接影响居民对地方的依恋。然而,在城市居民地方依恋的相关研究中,也存在间接效应。对调查结果的研究、政策和部门影响进行了详细讨论。

Disaster Risk Governance in Bangladesh: How Do NGOs Find Themselves in the Network? 孟加拉国的灾害风险治理:非政府组织如何在网络中找到自己?
IF 1.3 Q2 Social Sciences Pub Date : 2021-09-01 DOI: 10.1177/09754253211040205

The roles and responsibilities of state-led organizations have remained the primary focus of disaster risk governance (DRG) literature. While integration of NGOs into formal disaster risk reduction (DRR) has been persistently promoted by the recent United Nations’ DRG frameworks to support state interventions, the low uptake of embracing core principles of DRR by NGOs is noted. Tension within network governance of DRG, including state and non-governmental actors, is also reported by several scholars, particularly in developing countries, but has not been investigated empirically with greater details. To contribute to this research agenda, the study aims to explore how NGOs perceive and value their contributions to DRG. Based on a structured questionnaire survey with development activists (DAs) from NGOs in the southwest coastal region of Bangladesh, the study found that reactive interventions (emergency response and post-disaster support) by them was perceived to be the most critical focus of DRG despite changing theoretical and global perspectives towards pre-disaster preparedness and mitigative measures. Vertical network governance was favoured within NGOs’ own networks outside the state’s direct supervision, identifying a critical role played by local NGOs. The capacity of leadership of NGOs was promoted by the respondents who worked in decision-making positions within their organizations, whilst professionals with lack of experience within the NGO sector tended to favour state actors. The findings could be critical in understanding local capacities and in co-creating hazard specific plans using various stakeholders.
国家领导的组织的作用和责任仍然是灾害风险治理文献的主要关注点。尽管最近联合国支持国家干预的灾害风险减少框架一直在推动非政府组织融入正式的灾害风险降低,但非政府组织对纳入灾害风险减少核心原则的接受率很低。一些学者,特别是发展中国家的学者,也报告了DRG网络治理内部的紧张关系,包括国家和非政府行为者,但尚未进行更详细的实证调查。为了促进这一研究议程,本研究旨在探讨非政府组织如何看待和重视其对DRG的贡献。根据对孟加拉国西南沿海地区非政府组织发展活动家的结构化问卷调查,该研究发现,尽管对灾前准备和缓解措施的理论和全球视角发生了变化,但他们的反应性干预措施(应急响应和灾后支持)被认为是DRG最关键的重点。垂直网络治理在国家直接监督之外的非政府组织自己的网络中受到青睐,这表明地方非政府组织发挥了关键作用。在非政府组织中担任决策职位的受访者提高了非政府组织的领导能力,而在非政府部门缺乏经验的专业人士则倾向于支持国家行为者。这些发现对于了解当地能力和利用各种利益攸关方共同制定针对特定危险的计划至关重要。

The objectives of the current paper are to suggest measures to improve the taxation and tax collection mechanisms in selected cities of Karnataka. We review and reform (where necessary) bases of assessments of revenue streams and suggest enhancement of revenue sources by suitable mechanisms that can be implemented in all the selected cities. Finally, we estimate revenue capacities of the cities and recommend expansion capabilities. The methodology of the study involved visits to each of the selected 12 cities, examination of their audited financial statements, analysis of their major revenue sources and estimation of revenue capacities for each of the cities. We recommended measures to fix relevant policies to improve the system of tax collection and revenue generation mechanisms. Summarizing our findings, increasing revenue compliance from non-paying and unassessed properties and taxation of government properties of a commercial nature, increases the property tax base for all cities across the board. The next step is to increase values of properties, in accordance with market values in an economic sense, in a gradual manner. Water connections must be metered, given that water is a scarce resource, we find its revenue potential to be nearly the same as that from property tax.
本论文的目的是提出改善卡纳塔克邦选定城市税收和税收机制的措施。我们审查和改革(必要时)收入流评估基础,并建议通过在所有选定城市实施的适当机制来增加收入来源。最后,我们估计了城市的收入能力,并推荐了扩张能力。研究方法包括访问选定的12个城市中的每一个,审查其经审计的财务报表,分析其主要收入来源,并估计每个城市的收入能力。我们建议采取措施,制定相关政策,完善税收征收制度和创收机制。总结我们的调查结果,提高非付费和未评估房产的收入合规性,以及对商业性质的政府房产征税,全面提高了所有城市的房产税基础。下一步是根据经济意义上的市场价值,逐步增加房地产的价值。供水必须计量,因为水是一种稀缺资源,我们发现它的收入潜力与财产税几乎相同。

In this study, a coordination model based on the data of urban population and built-up areas from 2006 to 2015 is used to assess the relationship between population urbanization and urban sprawl across 654 cities in Mainland China. For analysis, 654 cities are divided into five categories (small city, medium city, large city, super city and mega city) and the relationship between population urbanization and urban sprawl is divided into four types (rapid growth of population, rapid expansion of land, shrinkage of population and land and coordinated development between population and land). The results show that 60.6% of cities are rapid expansion of land, 18.5% are rapid growth of population, 14.1% are shrinkage of population and land and only 6.9% of cities are coordinated development between population and land. Small, medium, large and super cities were characterized by rapid expansion of land, while mega cities featured rapid growth of population. The size of the cities decreased mainly because of the shrinkage of people and land while it increased because of the rapid expansion of land. The cities with shrinkage of population and land, and rapid growth of population are mostly distributed in the east of the Hu Line.
在本研究中,基于2006-2015年城市人口和建成区数据的协调模型,评估了中国大陆654个城市的人口城市化与城市蔓延之间的关系。分析将654个城市分为五类(小城市、中城市、大城市、特大城市),人口城镇化与城市蔓延的关系分为四类(人口快速增长、土地快速扩张、人口与土地萎缩、人口与陆地协调发展)。结果表明,60.6%的城市是土地的快速扩张,18.5%是人口的快速增长,14.1%是人口和土地的萎缩,只有6.9%的城市是人口与土地的协调发展。小、中、大、特大城市土地扩张较快,特大城市人口增长较快。城市规模的减少主要是因为人口和土地的减少,而城市规模的增加则是因为土地的快速扩张。人口和土地萎缩、人口快速增长的城市大多分布在胡线以东。

The concept of environmental flows and its application and enforcement is a main challenge in several developing countries. The services and benefits derived from the ecosystem are indispensable for sustaining the livelihood of people particularly living in coastal areas. Decision-makers often ignore ecosystems when referring to water allocation, as the supporters of ecosystems are less vocal as compared to other stakeholders. This study focuses on establishing guidelines for maintaining the minimum amount of flow known as environmental flow of Brunei River in Brunei Darussalam for the sustainability of its rich ecosystem. In this study, the flow of the river was simulated based on land use, climate change, and potential growth of industries using a Water Evaluation and Planning System as a computing tool. The study finds that the months of March and June (1.48 and 3.92 m3/s) are more vulnerable to low flow. It recommends a threshold value of 2.7 m3/s for the environmental flow of Brunei River essential to preserve its rich and diversified ecosystem.
环境流动的概念及其应用和执行是一些发展中国家面临的主要挑战。生态系统提供的服务和效益对于维持人民的生计,特别是生活在沿海地区的人民的生计是必不可少的。决策者在提及水资源分配时往往忽视生态系统,因为与其他利益相关者相比,生态系统的支持者声音较小。本研究的重点是为保持文莱达鲁萨兰国丰富生态系统的可持续性,制定维持文莱河环境流量的最低流量指南。在这项研究中,使用水资源评估和规划系统作为计算工具,根据土地利用、气候变化和工业潜在增长对河流流量进行了模拟。研究发现,3月和6月(1.48和3.92 m3/s)更容易受到低流量的影响。它建议文莱河的环境流量阈值为2.7 m3/s,这对保护其丰富多样的生态系统至关重要。

In Chennai, Development-Induced Displacement and Resettlement (DIDR) pushes the urban poor to resettlement sites in the outskirts of the city. One of those sites is Kannagi Nagar, located 15 km from the city centre, in which women suffer from more significant livelihood deprivation. As there is evidence of Information and Communication Technology (ICT) being useful in development, this study aims to explain the role of ICT in the livelihood restoration and enhancement of the social and financial capital for women in Kannagi Nagar. Through a case study with a blend of quantitative and qualitative techniques, the research incorporated a closed-ended questionnaire survey and interviews. Among the women, ICT use is prevalent, however, they have not fully optimized the potentials of ICT for livelihood restoration. The use is still limited to the purpose of maintaining the contacts they already have. However, some women have been able to use ICT, especially through their phones, for the restoration and enhancement of their social and financial capital. Nonetheless, to harness the full potential of ICT and strengthen women’s agency, access to ICT should be improved.
在金奈,发展引发的流离失所和重新安置(DIDR)将城市贫困人口推向城市郊区的安置点。其中一个地点是离市中心15公里的Kannagi Nagar,那里的妇女遭受更严重的生计剥夺。由于有证据表明信息通信技术(ICT)在发展中是有用的,本研究旨在解释ICT在卡纳吉纳加尔妇女生计恢复和社会金融资本增强中的作用。本研究以个案研究为例,结合定量与定性相结合的方法,采用封闭式问卷调查与访谈相结合的方法。在妇女中,信息通信技术的使用很普遍,然而,她们并没有充分发挥信息通信技术在恢复生计方面的潜力。其用途仍然局限于维持他们已有的联系。然而,一些妇女已经能够使用信息通信技术,特别是通过她们的电话,来恢复和增强她们的社会和金融资本。然而,为了充分利用信息和通信技术的潜力并加强妇女的作用,应改善信息和通信技术的使用。

COVID-19: Urban Vulnerability and the Need for Transformations 新冠肺炎:城市脆弱性和转型的必要性

The urban–rural divide in India has been the cause of labour flow to Indian cities, which have historically witnessed an insufficiency in planning. Moreover, widening social inequalities exacerbate the living conditions in Indian cities, pushing the migrant labourers from rural areas to the margins of urban spaces. Public policymakers have long turned a blind-eye to migrants, denying them essential social security. This study attempts to review how these factors have made urban space unwelcome to migrants from rural areas, edging them to a state of inability to sustain themselves, especially amidst the COVID-19 pandemic. It is also an attempt to re-evaluate the status of urbanization. The government imposed a sudden lockdown in 2020 to mitigate the effects of the COVID-19 outbreak, leading to a massive exodus of migrants from cities back to their homes. The study also seeks to account for the significance of economic planning and social security with regard to migrant labour.
印度的城乡差距一直是劳动力流向印度城市的原因,而印度城市在历史上一直存在规划不足的问题。此外,不断扩大的社会不平等加剧了印度城市的生活条件,将农村地区的移民劳工推向了城市空间的边缘。长期以来,公共政策制定者对移民视而不见,剥夺了他们基本的社会保障。这项研究试图回顾这些因素如何使城市空间不受农村地区移民的欢迎,使他们陷入无法维持生活的状态,尤其是在新冠肺炎大流行期间。这也是重新评估城市化状况的一种尝试。2020年,政府突然实施封锁,以减轻新冠肺炎疫情的影响,导致大量移民从城市返回家园。该研究还试图说明经济规划和社会保障对移徙劳动力的重要性。

Earnings and Investment Differentials Between Migrants and Natives: A Study of Female Street Vendors in Bengaluru City 外来人口与本地人口的收入与投资差异:对班加罗尔市女性街头小贩的研究

This article explores whether there exists any difference in the earnings of self-employed migrant and native street vendors in a metro city, and if so, in what ways this difference is prominent. In order to accomplish the objective, we have collected data from women street vendors from Bengaluru city. The results depict that although there is no significant difference in the earnings between native and migrant street vendors, a significant difference exists in the size of investments made by them, that is, to earn the same amount of income, migrants need to invest more than natives. Moreover, the results, based on the Oaxaca–Blinder decomposition method, indicate that the pre-labour market endowment factors do not make a significant contribution to the overall difference in the rate of returns. The difference, instead, mainly exists because of the coefficient differences, which can be attributed to discrimination.
本文探讨了大都市中个体经营的农民工和本地街头小贩的收入是否存在差异,如果存在,这种差异在哪些方面突出。为了实现这一目标,我们从班加罗尔市的女性街头小贩那里收集了数据。研究结果表明,尽管本地和移民街头小贩的收入没有显著差异,但他们的投资规模存在显著差异,也就是说,要获得相同的收入,移民需要比本地人更多的投资。此外,基于瓦哈卡-布林德分解方法的结果表明,劳动力市场前的禀赋因素对回报率的总体差异没有显著影响。相反,这种差异的存在主要是因为系数的差异,这可以归因于歧视。
