ABSTRACT With global warming forecast to continue into the foreseeable future, heat waves are very likely to increase in both frequency and intensity. In urban regions, these future heat waves will be exacerbated by the urban heat island effect, and will have the potential to negatively influence the health and welfare of urban residents. In order to investigate the health effects of the urban heat island (UHI) in Shanghai, China, 30 years of meteorological records (1975-2004) were examined for 11 first- and second-order weather stations in and around Shanghai. Additionally, automatic weather observation data recorded in recent years as well as daily all-cause summer mortality counts in 11 urban, suburban, and exurban regions (1998-2004) in Shanghai have been used. The results show that different sites (city center or surroundings) have experienced different degrees of warming as a result of increasing urbanization. In turn, this has resulted in a more extensive urban heat island effect, causing additional hot days and heat waves in urban regions compared to rural locales. An examination of summer mortality rates in and around Shanghai yields heightened heat-related mortality in urban regions, and we conclude that the UHI is directly responsible, acting to worsen the adverse health effects from exposure to extreme thermal conditions.

    ABSTRACT: Emerging Scholars Edition 2 Paving the Way Forward in Urbanization and Global Environmental Change Research [ Emerging Scholars Edition ] UGEC Viewpoints | No. 9 | July 2013 | www.ugec.org Dear friends of the UGEC project, I am delighted to share with you this ninth issue of UGEC Viewpoints — one of my favorite issues produced thus far! Over the years, the UGEC project has placed attention on creating capabilities among young scholars and practitioners offering opportunities for networking, collaboration and publication, and has organized several training workshops with other international organizations towards these efforts. The biannual Viewpoints publication has always been an avenue through which our colleagues working and doing research in the field of urbanization and global environmental change are able to showcase their expertise to the international community, and discuss key issues and gaps in knowledge critical for moving forward. This particular issue is no exception, but more so, highlights research from emerging scholars within the UGEC network. It seems most appropriate at this stage of the project to transition the focus of the Viewpoints towards our future scholars. Recently, there have been many exciting developments and discussions with respect to the Global Change Research Programmes and Projects, which are currently transitioning into the new 'Future Earth' research framework for global sustainability. This is an exciting process in which UGEC has continually been engaged, and runs in parallel with the third stage of our project which is now heavily focused on synthesis. This mix of reflection and synthesis as well as looking towards the project's future and that of urban/environmental research has been quite an exciting endeavor — a process that will continue throughout the next few years and for which we are planning a number of activities, namely our 2 nd

    DESCRIPTION: Chapter 4: Wetlands are recognized worldwide for offering ecosystem services essential for human livelihood. In urban landscapes, some of the key wetland ecosystem services include, but are not limited to, flood attenuation, control of surface and ground water pollution, tourism and recreation, carbon sequestration and water supply (MEA, 2005). However, over years of urban and industrial development, anthropogenic induced modifications on riverine systems and wetlands have changed their physical, chemical, and biological functioning (Hein et al., 2009; MEA, 2005; Weilhoefer et al., 2008). This has not only deteriorated the resilience of these fragile natural systems, but has also increased the vulnerability of communities that directly or indirectly depend on them for the ecosystem services they provide.

    ABSTRACT: The study explores the interdecadal and seasonal variability of the urban heat island (UHI) intensity in the city of Athens. Daily air temperature data from a set of urban and surrounding non urban stations over the period 1970–2004 were used. Nighttime and daytime heat island revealed different characteristics as regards the mean amplitude, seasonal variability and temporal variation and trends. The difference of the annual mean air temperature between urban and rural stations exhibited a progressive statistically significant increase over the studied period, with rates equal to + 0.2 °C/decade. A gradual and constant increase of the daytime UHI intensity was detected, in contrast to the nighttime UHI intensity which increases only in summer, after the mid 1980s. UHI phenomenon was found to be related to higher increasing rates of hot days frequency at the urban stations. It was found that the interaction between heat waves and heat island in Athens, results to pronounced amplification of nocturnal UHI intensity under exceptionally hot weather.
