‘We Live on Estimates': Everyday Practices of Prepaid Electricity and the Urban Condition in Maputo,Mozambique

This article examines the transition to prepaid electricity happening in Maputo, Mozambique, in order to reflect on the contemporary geographies of urban energy infrastructure and urbanization in sub‐Saharan Africa and other cities of the South. The article draws on fieldwork and archival research conducted in 2013 and 2014, arguing that prepayment constitutes a productive juncture in the urban experience of electricity infrastructure in Maputo's postcolonial moment, not merely a neutral technology or a disciplining technique of government (as argued by some scholarship). The article examines the multiple rationalities implicated in the use of the electricity infrastructure via prepayment and the organization of urban life it engenders (and of which it is also a product) by focusing on the everyday practices surrounding prepaid electricity of urban dwellers in neighbourhoods where the ‘modern infrastructural ideal' may never be fully realized. As a result, it contributes to an understanding of the experience of urban energy in cities where ‘slum urbanism', uncertainty and provisionality are dominant aspects of the urban condition.     

The Kafka quagmire for the poor in India

Khare and Varman present a compellingly pessimistic analysis of the plight of the poor in India. The dilemmas of the poor are often exacerbated by large corporations seeking to find ways to market products to impoverished emerging market consumers. In India, consumers are frequently hurt by these initiatives, small retailers may suffer, while corruption and trickery by petty bureaucrats and ruthless landlords help the rich get richer at the expense of the poor. The article by Khare and Varman is a scathing indictment based on detailed ethnographic evidence but it reveals only a fraction of the disadvantages and traps of disempowerment facing those Indians living lives of great precarity. In this comment, we seek to build upon Khare and Varman’s insightful analysis both in order to reinforce their conclusions about the Kafkaesque existence of India’s poor and to introduce some further considerations and complications that make the quagmire even more entrapping. We focus on four sources of these problems: patriarchy, bureaucracy and corruption, class and caste power and hierarchies, and uneven and inadequate infrastructure. We also highlight some largely individual and non-government initiatives that may offer hope of escaping this quagmire for the poor.     

Willingness to Pay for Green Products in Air Travel: Ready for Take‐Off?

We examine the willingness to pay (WTP) for green products in air travel. Green products in aviation are supplementary services, which are sold on top of the travel service (e.g. carbon offsets, organic on‐board food). We identify a set of potential green products in aviation and report the preferences for additional airline services of 811 Swiss air travellers using an adaptive choice‐based conjoint survey. We find that 20% of those passengers who are interested in purchasing supplementary services show a considerable WTP for green products. The green segment differs from the regular segment only in terms of behavioural features, not in terms of demographic or socio‐economic characteristics.

Role of Green Governance in Achieving Sustainable Urbanization in China

Since economic reforms began in 1978, China＇s urban population has increased by half a billion. Over the next 20years, cities will likely add another 300 million people through local population growth, migration and the integration of nearby rural areas, Cities account for the majority of resource use and pollution so achieving greener growth will depend on developing and implementing a more sustainable urbanization model. China＇s leaders have responded to these challenges with ambitious goals and comprehensive environmental laws and regulations. These have so far not significantly reduced the harm from air, water and soil pollution.＂ in large measure because China ＂s green governance does not match its green ambitions. Drawing on the World Bank ＇s work on green growth and a recent joint urbanization study by the Development Research Center of China＇s State Council and the Worm Bank, this paper reviews recent academic research on green governance in urban China and discusses its main implications in the context of emerging global green growth concepts.     

What about people in cycle network planning? applying participative multicriteria GIS analysis in the case of the Athens metropolitan cycle network

The bicycle is gaining ground as an inexpensive, fast, healthy, and enjoyable mode of transport, but the development of cycle infrastructures appears to be a necessary prerequisite for supporting further growth in cycling rates. Thus far, few studies have developed comprehensive methodologies for the prioritisation of cycling infrastructure investments, and the role of end users has been underestimated in this process. The unique relationship that cyclists develop with the bicycle itself, their co-cyclists, bicycle facilities, and the urban environment as a result of sensory, kinaesthetic, symbolic, or even political reasons can assist in designing cycle facilities that are more efficient and closer to fulfilling the needs and desires of users. We propose a comprehensive four-step methodology for cycle network planning, which both accounts for the city structure and the zones in which higher cycling demand is possible and uses participative multicriteria GIS processes to incorporate cyclists’ views with regard to choosing the cycle network segments. Our case study is Athens, Greece, where cycling facilities are few and heavily fragmented, although cycling demand has recently grown. This methodology may be useful for cities attempting to introduce and prioritise cycling infrastructures because it focuses on determining where cyclists would prefer to cycle to make such investments more successful in attracting users.     

Progress of e-development in China since 1998

In this paper, a holistic analytical framework for tracing and understanding the progress of e-development is developed and adopted in an empirical case study of China’s e-development since 1998. In particular, the progress is analyzed systematically by benchmarking various ICT infrastructure and e-devices, the composition of Internet users, and the key dimensions of e-government, e-working, e-commerce, and e-networking. In addition, the questions of whether the geographical digital divide in the country has been narrowed is examined. Our findings show that (1) China has made noticeable progress in the e-development since 1998; yet, progress varied in different dimensions; (2) based on the overall performance, 2004 can be considered as the watershed for China to move from the formative stage to the developmental stage; (3) during the e-development, digital disparities in China have dramatically decreased at the provincial level, however, the urban-rural digital gap widened. We suggest that other than promoting affordable ICT possession, the wider and more diversified e-applications for different walks of life will be important for China to move towards the mature stage.     

An empirical analysis of green convention attendees' switching intentions

This study aims at proposing to test a research model to gain a better understanding of the relationships among the dimensions of experiential quality, green experiential satisfaction, green alternative attractiveness, green service fairness, green variety-seeking, and green switching intentions. The study's findings are based on structural equation model analysis of a convenience sample of 650 attendees at the 13th International Green Building and Energy-Savings Exhibition 2016 in Chongqing, China. The results of this analysis contribute to the services marketing theory by providing additional insights into green switching intentions, the dimensions of experiential quality, green experiential satisfaction, green alternative attractiveness, green service fairness, and green novelty-seeking. The study's results will assist green convention management in developing and implementing market-orientated service strategies to increase the dimensions of experiential quality and green experiential satisfaction, enhance green alternative attractiveness, green service fairness, and green novelty-seeking, and decrease green switching intentions.     

Electrification of a city bus network—An optimization model for cost-effective placing of charging infrastructure and battery sizing of fast-charging electric bus systems

The deployment of battery-powered electric bus systems within the public transportation sector plays an important role in increasing energy efficiency and abating emissions. Rising attention is given to bus systems using fast charging technology. This concept requires a comprehensive infrastructure to equip bus routes with charging stations. The combination of charging infrastructure and bus batteries needs a reliable energy supply to maintain a stable bus operation even under demanding conditions. An efficient layout of the charging infrastructure and an appropriate dimensioning of battery capacity are crucial to minimize the total cost of ownership and to enable an energetically feasible bus operation. In this work, the central issue of jointly optimizing the charging infrastructure and battery capacity is described by a capacitated set covering problem. A mixed-integer linear optimization model is developed to determine the minimum number and location of required charging stations for a bus network as well as the adequate battery capacity for each bus line. The bus energy consumption for each route segment is determined based on individual route, bus type, traffic, and other information. Different scenarios are examined in order to assess the influence of charging power, climate, and changing operating conditions. The findings reveal significant differences in terms of required infrastructure. Moreover, the results highlight a trade-off between battery capacity and charging infrastructure under different operational and infrastructure conditions. This paper addresses upcoming challenges for transport authorities during the electrification process of the bus fleets and sharpens the focus on infrastructural issues related to the fast charging concept.
