Although urbanization in smaller cities is arguably not imperative, the future of urban living is no longer expected to be principally in mega-cities. People increasingly live in intermediate and smaller cities, in line with the proportion of people residing in urban areas, which is also gradually rising. Smaller cities in Indonesia, like other smaller cities in the developing world, are relatively densely populated, and many of them are experiencing extended urbanization, thereby exceeding their administrative boundaries. This paper seeks to explore the factors triggering urban development in these smaller cities, for a case in Indonesia. Urban change in Cirebon Region has accelerated in recent years, very much in line with the decentralization policy in Indonesia. This paper shows how urban change is in!uenced by economic restructuring, which encourages people to live closer to the core of the region, representing a new link between the core and new emerging urban areas in the region. This paper reveals these attributes to identify the characteristics of smaller urban centres, thereby contributing a more nuanced image of small cities in general.

This article examines notions of cultural identity and authenticity and how these notions are articulated in the small city of Kaili in Guizhou Province, an ethnically diverse region. Despite its urban status, Kaili has been branded by the local government as a yuanshengtai tourist destination. This Chinese term literally translates as “original ecology” but is used in ordinary conversation to denote a cultural authenticity in which people exist in quiet harmony with nature. Promotional literature uses the term to tout the ethnic cultural practices that mainly occur in the villages of Kaili’s municipal periphery. In contrast, many local urban inhabitants—although amenable to the promotion of Kaili as a tourist destination—have rejected the notion that the city itself could be considered culturally authentic, and proudly declare themselves “fake” ethnic minorities, as against the “genuine” ethnic people of surrounding villages. These small-city inhabitants have also defined themselves against big-city visitors by attributing to the visitors a naïve fascination with cultural authenticity, while themselves remaining aloof from such practices. The cultural authenticity discourse in Kaili has thus facilitated a reordering of social and spatial hierarchies, as blasé small-city residents define themselves against both culturally authentic rural people and authenticity-seeking big-city tourists. In analyzing this, the article draws out the broader implications regarding PRC notions of ethnicity, cultural practices, heritage, and identity.

There is a growing literature which documents the importance of early life environment for outcomes across the life cycle. Research, including studies based on Irish data, demonstrates that those who experience better childhood conditions go on to be wealthier and healthier adults. Therefore, inequalities at birth and in childhood shape inequality in wellbeing in later life, and the historical evolution of the mortality and morbidity of children born in Ireland is important for understanding the current status of the Irish population. In this paper, I describe these patterns by reviewing the existing literature on infant health in Ireland over the course of the 20th century. Up to the 1950s, infant mortality in Ireland (both North and South) was substantially higher than in other developed countries, with a large penalty for those born in urban areas. The subsequent reduction in this penalty, and the sustained decline in infant death rates, occurred later than would be expected from the experience in other contexts. Using records from the Rotunda Lying-in Hospital in Dublin, I discuss sources of disparities in stillbirth in the early 1900s. Despite impressive improvements in death rates since that time, a comparison with those born at the end of the century reveals that Irish children continue to be born unequal. Evidence from studies which track people across the life course, for example research on the returns to birthweight, suggests that the economic cost of this early life inequality is substantial.

At the outset of the United Nations Convention on the Rights of the Child, the Committee on the Rights of the Child identified four of its provisions (non-discrimination; best interests of the child as a primary consideration; life, survival and development; and participation) as ‘general principles’. This approach has shaped implementation of, advocacy for and the scholarship on the Convention. The use of general principles has the potential to make a significant contribution in other areas of human rights law provided that the principles are selected carefully and address the distinct issues at the root of potential rights violations for particular rights-holders.

Food production and consumption for cities has become a global concern due to increasing numbers of people living in urban areas, threatening food security. There is the contention that people living in cities have become disconnected with food production, leading to reduced nutrition in diets and increased food waste. Integrating food production into cities (urban agriculture) can help alleviate some of these issues. Lack of space at ground level in high-density urban areas has accelerated the idea of using spare building surfaces for food production. There are various growing methods being used for food production on buildings, which can be split into two main types, soil-less systems and soil-based systems. This paper is a holistic assessment (underpinned by the triple bottom line of sustainable development) of these two types of systems for food production on buildings, looking at the benefits and limitation of each type in this context. The results illustrate that soil-less systems are more productive per square metre, which increases the amount of locally grown, fresh produce available in urban areas. The results also show that soil-based systems for cultivation on buildings are more environmentally and socially beneficial overall for urban areas than soil-less systems.

In urban areas, interchange spacing and the adequacy of design for weaving, merge, and diverge areas can significantly influence available capacity. Traffic microsimulation tools allow detailed analyses of these critical areas in complex locations that often yield results that differ from the generalized approach of the Highway Capacity Manual. In order to obtain valid results, various inputs should be calibrated to local conditions. This project investigated basic calibration factors for the simulation of traffic conditions within an urban freeway merge/diverge environment. By collecting and analyzing urban freeway traffic data from multiple sources, specific Iowa-based calibration factors for use in VISSIM were developed. In particular, a repeatable methodology for collecting standstill distance and headway/time gap data on urban freeways was applied to locations throughout the state of Iowa. This collection process relies on the manual processing of video for standstill distances and individual vehicle data from radar detectors to measure the headways/time gaps. By comparing the data collected from different locations, it was found that standstill distances vary by location and lead-follow vehicle types. Headways and time gaps were found to be consistent within the same driver population and across different driver populations when the conditions were similar. Both standstill distance and headway/time gap were found to follow fairly dispersed and skewed distributions. Therefore, it is recommended that microsimulation models be modified to include the option for standstill distance and headway/time gap to follow distributions as well as be set separately for different vehicle classes. In addition, for the driving behavior parameters that cannot be easily collected, a sensitivity analysis was conducted to examine the impact of these parameters on the capacity of the facility. The sensitivity analysis results can be used as a reference to manually adjust parameters to match the simulation results to the observed traffic conditions. A well-calibrated microsimulation model can enable a higher level of fidelity in modeling traffic behavior and serve to improve decision making in balancing need with investment.

Tourism has become the world’s largest industry, and has overcome economic sectors such as oil production and car manufacturing. It is foreseen that tourism will continue to expand in the future and will spread all around the world. In Europe, the tourism sector is made of 440 million international arrivals that are responsible for accounting about 10% of European GDP and generating 20 million jobs. Coastal destinations are major tourist destinations. This is due to their physical attractiveness, beautiful landscapes, and fine open space for leisure activities. Nevertheless, sun-sea-sand tourism depends very much on the environment. In this way, coastal destination ought to be properly planned so they do not exceed the limits of acceptable change (LAC) of the ecosystems, and keep their attractiveness. Being an economic activity, it is essential that coastal tourism is competitive, and show capacity to attracting new and enlarged markets. Coastal destinations should diversify its products and services, smooth seasonality and become more competitive. Diversification should create more growth and employment, and also reduce environmental, economic and social impact caused by the concentration of tourism activity in a few months of the year and the use of only the beach resource. This paper aims at analyzing the application of the competitiveness concept to tourism in coastal areas (Ria de Aveiro region, Central Portugal), and draws attention to the principle of environmental, economical and social sustainability.

Understanding the dynamics of urban ecosystem services is a necessary requirement for adequate planning, management, and governance of urban green infrastructure. Through the three-year Urban Biodiversity and Ecosystem Services (URBES) research project, we conducted case study and comparative research on urban biodiversity and ecosystem services across seven cities in Europe and the United States. Reviewing > 50 peer-reviewed publications from the project, we present and discuss seven key insights that reflect cumulative findings from the project as well as the state-of-the-art knowledge in urban ecosystem services research. The insights from our review indicate that cross-sectoral, multiscale, interdisciplinary research is beginning to provide a solid scientific foundation for applying the ecosystem services framework in urban areas and land management. Our review offers a foundation for seeking novel, nature-based solutions to emerging urban challenges such as wicked environmental change issues.

The literature on the governance of social-ecological systems increasingly recognizes a key role of bridging organisations (BOs) in transition processes towards sustainability. BOs can be defined as facilitators who allow for interorganisational collaboration. Our paper provides a more nuanced understanding of specific BO activities and their contributions towards urban sustainability. Our analysis is based on applying three complementary methodological angles (drawing on geolocalised data, interviews and action research) to 20 years of urban renovation investments in the city-region of Brussels. We distinguish between multi-scale, multi-actor and multi-dimensional tensions in urban renovation programmes and link these tensions to bridging challenges for BOs. Results suggest that the corresponding three types of bridging roles form a trilemma rather than a trilogy: the BOs in study have mediated one tension by de facto exacerbating another. Lessons from action research suggest that a wider use of temporality and shared language to communicate about urban renovation projects could attenuate the bridging trilemma.
