Purpose – This work offers an investigation of the planning and implementation of climate-adaptation and vulnerability-reduction strategies in coastal mega-cities of the Global South, utilizing Kolkata, India, as a case study. This research is designed to identify factors that aid the implementation of climate-centered action in resource-constrained environments of developing countries and provide a set of policy guidelines reflecting best practices.

Methodology/approach – This work draws principally upon analysis of semistructured field interviews conducted in Kolkata, India, during December 2010 and January 2011. The findings are informed by additional data sources as well, including field observations, informal dialogues and meetings, and a review of secondary literature.

Findings – This work identifies several key success factors, including organizational restructuring, resource redistribution, technological innovation, use of external consultants, coupling of climate and development projects, and integration of climate approaches into infrastructure projects.

Research limitations – This research draws upon Kolkata as a case study; thus the work's broader applicability and utility depend on the similarities between the situation in Kolkata and that of other urban areas. As a local study, this work may also offer fewer insights for regional and national policy.

Originality and value – This work fills a timely, unmet need for a greater understanding of climate-adaptation action in the context of cities of the developing world. The extensive use of personal interviews provides unique insights into the minds of planning officials and professionals and draws upon their practical experience to draw lessons for a wide range of similar environments.

Reports on joint efforts by the municipality of Tehran and the scientific body to prepare and implement earthquake reduction policies in the Tehran region, a mega‐city with an approximate population of 10 million people. Focuses specifically on analyzing the seismic vulnerability of the city by considering topography, geology, seismotectonics and seismicity, geotechnical aspects, structural performance, lifelines, emergency services, socio‐economic condition, and search and rescue capabilities. Defines 14 seismic vulnerability indexes for the city and relative vulnerability for 22 further sub‐divisions. Discusses the analyzed data and results. Concludes that a 0.35g scenario could produce a dramatic outcome in Tehran, with extensive damage to buildings and significant numbers of deaths and injuries.

With the dramatic transformation of China’s industrial landscape, since the late 1990s, adaptive reuse of industrial heritage for cultural purposes has become a widely occurring phenomenon in major Chinese cities. The existing literature mainly focusses on specific cases, yet sees heritage conservation similarly at both national and regional scale and rarely identifies the main factors behind the production of China’s industrial-heritage reuse. The purpose of this paper is to examine the differences in heritage reuse outcomes among three Chinese mega-cities and explore the driving factors influencing the differences.

This paper compares selected industrial-heritage cultural precincts in Beijing, Shanghai and Chongqing, and explores the local intervening factors influencing differences in their reuse patterns, including the history of industrial development, the availability of the nineteenth and/or twentieth century industrial buildings, the existence of cultural capital and the prevalence of supportive regional government policy.

The industrial-heritage reuse in the three cities is highly regional. In Beijing, the adaptation of industrial heritage has resulted from the activities of large-scale artist communities and the local government’s promotion of the city’s cultural influence; while in Shanghai, successful and more commercially oriented “sea culture” artists, private developers in creative industries and the “creative industry cluster” policy make important contributions. Chongqing in contrast, is still at the early stage of heritage conservation, as demonstrated by its adaptive reuse outcomes. Considering its less-developed local cultural economy, Chongqing needs to adopt a broader range of development strategies.

The paper contributes to knowledge by revealing that the production of industrial-heritage cultural precincts in Chinese mega-cities is influenced by regional level factors, including the types of industrial heritage, the spontaneous participation of artist communities and the encouragement of cultural policy.

The purpose of this paper is to evaluate public transportation efficiency in larger cities. Global agreements to decrease environmental emissions in the future (CO₂), world‐wide decreasing reserves of oil, and growing population in larger cities is the main motivation to develop efficiency benchmarking measurement models for public transportation systems, and gives reason for this research work. Also, from the point of view of the city, data envelopment analysis (DEA) based efficiency measurement has not been researched earlier, which is another motivation for this study from the method development perspective.

Four different DEA‐based efficiency benchmarking models are used to evaluate public transportation efficiency in larger cities. Data are from year 2001, and amount of analyzed cities in smaller DEA model is 52 and in larger 43. This gives statistical significance and efficiency measurement confidence over the results.

Medium‐sized, old and central European cities such as Bern, Munich, Prague and Zürich show frontier performance in all four models. Mega‐cities fail to reach frontier and/or good performance in small “services used” DEA model. However, some other medium‐sized cities show contrarian behaviour for “space used” DEA model. Lowest performance is more divergent in the analyses, but is found from Spanish cities, Athens, Middle East and North America. The author also found support from regression analysis that higher DEA efficiency results in lower share of private car use in large cities.

This research work uses only year 2001 data, and should be repeated in the future as public transportation data18base is being updated. The research is also limited on the use of DEA method, and other efficiency measurement methods should be used to verify the results further.

According to the author's knowledge, this research work is seminal from the city‐level DEA efficiency benchmarking studies concerning public passenger transportation systems. Earlier research works have concerned actors (e.g. bus companies or rail operators), but the overall picture from the city level has not been researched before.

The purpose of this paper is to rethink the focus of the smart cities debate and to open it to policymaking and strategy considerations. To this end, the origins of what is termed normative bias in smart cities research are identified and a case made for a holistic, scalable and human-centred smart cities research agenda. Applicable across the micro, mezzo and macro levels of the context in which smart cities develop, this research agenda remains sensitive to the limitations and enablers inherent in these contexts. Policymaking and strategy consideration are incorporated in the agenda this paper advances, thus creating the prospect of bridging the normative and the empirical in smart cities research.

This paper queries the smart cities debate and, by reference to megacities research, argues that the smart city remains an overly normatively laden concept frequently discussed in separation from the broader socio-political and economic contexts in which it is embedded. By focusing on what is termed the normative bias of smart cities research, this paper introduces the nested clusters model. By advocating the inclusion of policymaking and strategy considerations in the smart cities debate, a case is made for a holistic, scalable and human-centred smart cities agenda focused, on the one hand, on individuals and citizens inhabiting smart cities and, on the other hand, on interdependencies that unfold between a given smart city and the context in which it is embedded.

This paper delineates the research focus and scope of the megacities and smart cities debates respectively. It locates the origins of normative bias inherent in smart cities research and, by making a case for holistic, scalable and human-centred smart cities research, suggests ways of bypassing that bias. It is argued that smart cities research has the potential of contributing to research on megacities (smart megacities and clusters), cities (smart cities) and villages (smart villages). The notions of policymaking and strategy, and ultimately of governance, are brought into the spotlight. Against this backdrop, it is argued that smart cities research needs to be based on real tangible experiences of individuals inhabiting rural and urban space and that it also needs to mirror and feed into policy-design and policymaking processes.

The paper stresses the need to explore the question of how the specific contexts in which cities/urban areas are located influence those cities/urban areas’ growth and development strategies. It also postulates new avenues of inter and multidisciplinary research geared toward building bridges between the normative and the empirical in the smart cities debate. More research is needed to advance these imperatives at the micro, mezzo and macro levels.

By highlighting the connection, relatively under-represented in the literature, between the normative and the empirical in smart cities research, this paper encourages a more structured debate between academia and policymakers focused on the sustainable development of cities/urban areas. In doing so, it also advocates policies and strategies conducive to strengthening individuals’/citizens’ ability to benefit from and contribute to smart cities development, thereby making them sustainable.

This paper makes a case for pragmatic and demand-driven smart cities research, i.e. based on the frequently very basic needs of individuals and citizens inhabiting not only urban but also rural areas. It highlights the role of basic infrastructure as the key enabler/inhibitor of information and communication technology-enhanced services. The nested clusters model introduced in this paper suggests that an intimate connection exists between individuals’ well-being, their active civic engagement and smart cities sustainability.

This paper delineates the relationship between megacities and smart cities research. It identifies the sources of what is termed normative bias in smart cities research. To address the implications of that bias, a nested clusters model for smart cities is introduced, i.e. a conceptual framework that allows us to redraw the debate on smart cities and establish a functional connection between the array of normatively laden ideas of what a smart city could be and what is feasible, and under which conditions at the policymaking level.

The notion of sustainability broadly builds upon the development of the present without hampering the needs of the future generation. Accordingly, the contemporary development programmes, in general, emphasise on minimising the adverse bearings of climate change and arresting the irreversible ecological degradation following the implementation of the growth-oriented economic models. While such idea of sustainable development is expected to be applied across different sectors, the traditional urban development projects such as the Integrated Development of Small and Medium Towns (IDSMT) (1979), the Mega-City Scheme (1993), and the Jawaharlal Nehru National Urban Renewal Mission (JNNURM) (2005) focussed mainly on physical infrastructure with inadequate emphasis on the ecological aspects and sustainability. However, with the experiences of globalisation and the negative impact of changing climate, the recent urban development initiatives across the world have gone through considerable redesigning, and the idea of eco-city, compact city, sustainable city, etc., have taken the central place in the project proposals. In this connection, the Smart City Mission (SCM) (2015) of the Government of India has emerged as an important initiative to facilitate improvement in the standard of living along with economic growth through the development of urban infrastructure and integration with intelligent technologies. This chapter attempts to understand how the projects under the SCM have incorporated various ecological aspects to transform the cities into liveable and sustainable ones for the future generation. Using secondary data and carrying out a comparative analysis of selected smart city proposals, this chapter finds that there is still a lack of adequate emphasis on ecological sustainability in many smart city proposals. This chapter suggests revisiting the smart city proposals, and initiatives should be made towards the development of urban areas in a sustainable way.

Affordability and lifestyle choices in housing are critical to meet basic human needs for shelter, security and wellbeing. The meaning of a house for a particular group of people and what is ‘affordable’ for a particular community is the critical issue. Dhaka, the capital of Bangladesh, has greater population density and rate of expansion compared to almost any other mega cities of Asia. The historic core of the city known as old Dhaka is a combination of several traditional neighborhoods. Houses in these traditional neighborhoods are not only places to live, rather an integral unit of a social system, having a good mix of place of work and individual expression in living. They also show flexibility and adaptability (with more scope for personalization and individual life style choices) compared to the contemporary housing stock. One of the success factors in these traditional houses is the healthy mix of the income ranges to avoid a ghetto effect of low cost housing. The recent rapid urbanization has led to a discontinuity of the traditional housing form of old Dhaka, leading to a disintegration of the mix of lifestyle choices and affordability. Following popular market trends, they are often replaced by housing blocks in a higher density ignoring the need for a diverse mix. This paper studies the traditional housing of old Dhaka with two case study neighborhoods. Several elements of housing like the common price, materials and construction, space layout, scale, social space, facades, street interface, etc are selected for a qualitative study. Local residents interview, archival records, maps, Plans, figure-ground, aerial images are used to analyze, identify and demonstrate the elements that made them socio-culturally sustainable and affordable for the community. With the analysis, lessons from the traditional housing form that may contribute to the new housing in Dhaka are identified.

The advent and wide use of new digital technologies suggests that the internet is becoming a powerful new media for the imagination of city space. If this is the case then issues concerning urban representation on social media platforms such as Wikipedia provide an area of overlap and interest between urban studies and information studies. The purpose of this paper is to examine the representation of Manila, Philippines, one of the world’s major mega cities, on the popular online encyclopedia Wikipedia.

The author’s broad approach to the study of Wikipedia is qualitative in nature. For this study the entire Metro Manila article was downloaded on March 16, 2015 and subjected to textual analysis.

While the Wikipedia article on Manila cannot be classified as promotional, it is clear that much of the city remains invisible in this work. Such a puzzle becomes understandable when we examine the urban studies literature where we find that the spatial logic of the city itself helps conceal much from view, so that what we read on Wikipedia is a view from the islands of privilege rather than the oceans of marginalization that make up much of the city’s spatial form. If such a spatial structure is to change, representations such as found on Wikipedia need to be challenged.

Wikipedia is a key element of today’s information infrastructure yet despite its importance it remains relatively understudied within the field of information science. More specifically, the role of Wikipedia in representing cities, the dominant settlement form in the world today, has not been previously studied.
