Increasing urbanization patterns have resulted in significant and serious environmental health concerns (e.g. caused by a lack of physical activity). Urban planners face the challenge of developing healthy, resilient, and sustainable urban environments. This chapter addresses this challenge from an urban landscape perspective, promoting a socioecological approach, and recognizing that landscapes are shaped in close interaction between nature and culture—with cities being an ultimate example of human shaping and impact. It provides examples of how urban landscapes have contributed to better public health, from urban agriculture and community gardening, to therapeutic settings and urban wildscapes. Landscape-related approaches such as green urbanism, urban resiliency, and biophilic urbanism are introduced and examples are offered of how cities have worked with these. Suggestions are provided for the planning and development of health-promoting urban landscapes.

The well-known urban heat island (UHI) effect recognizes prevailing patterns of warmer urban temperatures relative to surrounding rural landscapes. Although UHIs are often visualized as single features, internal variations within urban landscapes create distinctive microclimates. Evaluating intraurban microclimate variability presents an opportunity to assess spatial dimensions of urban environments and identify locations that heat or cool faster than other locales. Our study employs mobile weather units and fixed weather stations to collect air temperatures across Roanoke, Virginia, USA, on selected dates over a two-year interval. Using this temperature data, together with six landscape variables, we interpolated (using Kriging and Random Forest) air temperatures across the city for each collection period. Our results estimated temperatures with small mean square errors (ranging from 0.03 to 0.14); landscape metrics explained between 60 and 91% of temperature variations (higher when the previous day’s average temperatures were included as a variable). For all days, similar spatial patterns appeared for cooler and warmer areas in mornings, with distinctive patterns as landscapes warmed during the day and over successive days. Our results revealed that the most potent landscape variables vary according to season and time of day. Our analysis contributes new dimensions and new levels of spatial and temporal detail to urban microclimate research.

Abstract Urban landscapes can—and do—influence multiple aspects of our lives, including our overall quality of life and disaster resilience. Research has confirmed that some populations experience negative outcomes in disasters at least partially attributed to poorly designed urban environments; and women's and girls’ resilience in particular can be impacted by their experience of the urban landscape. In response, urban designers have an opportunity and an obligation to incorporate gender-sensitive design approaches in all of their projects to ensure the whole community has access to the benefits of urban landscapes. This chapter examines current evidence and strategies for successful urban design that supports resilience in women and the cities they occupy.

While many global societies have undergone radical transformations, places have suffered from the irreversible loss of public memory. The value of continuity in the urban landscape has gradually declined due to the culture of “avant-gardism.” This article explores the enduring values necessary for human cohabitation and aesthetic qualities inherent in the rapidly changing urban environments of today. It draws attention to the ethical significance of continuity as the whole notion of “place” hinges, and argues that the experience of urban continuity in everyday life is an intrinsic and instrumental factor for our sense of identity, well-being, and belonging. Continuity, as predicated on human existence, is essential for the evolutionary, ecological, cognitive, cultural, and spiritual experience of the shared environment. The proposed dimensions of an aesthetic continuity are intended to provide a normative and pragmatic framework useful for application to placemaking in ever-changing urban environments.

The period since the 1960s has been characterised by growing societal concern with urban heritage protection and the development of legislative, fiscal and urban planning instruments that seek to ensure the protection and enhancement of historic buildings and environments. International organisations such as UNESCO and European level documents such as the European Spatial Development Perspective (ESDP) have stressed the cultural and economic value of the ‘wise management of natural and cultural heritage’. Since the 1970s many cities have sought to redefine and regenerate themselves through a revalorisation of their past and the protection and enhancement of their historic urban landscapes. Urban heritage has thus often come to be seen as a component of the territorial capital of places, and often had a symbiotic relationship with the objective of urban regeneration. However, urban heritage is not a static concept and ideas about what constitutes heritage, the value of different historic urban environments, and the contribution they can make to city development and regeneration continue to evolve. This paper reflects on this evolution in the context of the English planning system and illustrates some key trends and issues surrounding urban heritage through a consideration of recent and ongoing heritage related planning episodes in the northern English city of Liverpool.

Native species are increasingly living in urban landscapes associated with abiotic and biotic changes that may influence patterns of phenotypic selection. However, measures of selection in urban and non-urban environments, and exploration of the mechanisms associated with such changes, are uncommon. Plant–animal interactions have played a central role in the evolution of flowering plants and are sensitive to changes in the urban landscape, and thus provide opportunities to explore how urban environments modify selection. We evaluated patterns of phenotypic selection on the floral and resistance traits of Gelsemium sempervirens in urban and non-urban sites. The urban landscape had increased florivory and decreased pollen receipt, but showed only modest differences in patterns of selection. Directional selection for one trait, larger floral display size, was stronger in urban compared to non-urban sites. Neither quadratic nor correlational selection significantly differed between urban and non-urban sites. Pollination was associated with selection for larger floral display size in urban compared to non-urban sites, due to the differences in the translation of pollination into seeds rather than pollinator selectivity. Thus, our data suggest that urban landscapes may not result in sweeping differences in phenotypic selection but rather modest differences for some traits, potentially mediated by species interactions.

A crucial element in the human search for well-being is achieving a sense of identity within, and belonging to, the landscape in which we live. Landscape should be understood as not only the visible environment but the affective values we attach to it and how we shape it in our mind’s eye. These inner reflections of our landscapes constitute one of our richest archives, in particular, in terms of creating and passing down to future generations our cultural memories. The current paper is a review of literature on the concepts of urban heritage conservation, and, in particular, the development of the historic urban landscape (HUL) approach, with reference to the role and contribution of cultural memory and its presence in the urban landscape. We also investigate how the notions of place attachment and identity interrelate with cultural memory to elucidate how such interrelations can contribute to human psychosocial well-being and quality of life (QOL). This review points to the neglected role of cultural memory in the maintenance of psychosocial well-being in HULs, a topic which requires further research to deepen our understanding about its importance in urban environments.

This study examines how people value their historic urban landscapes through participatory heritage websites. These websites are online places where citizens actively contribute to the conservation of urban heritage. Taking UNESCO’s 2011 Recommendation on the Historic Urban Landscape as its theoretical starting point, this study understands urban landscapes as (1) dynamic, because they change over time; (2) multilayered, as different generations and communities contribute in diverse ways to the development of urban landscapes; and (3) mediated through digital technologies such as participatory heritage websites. Furthermore, this UNESCO recommendation is used to make a distinction between the kinds of heritage discussed on the websites (attributes) and the significance attached to it (values). Through a qualitative content analysis of 20 participatory heritage websites from various Dutch and English cities, the study examines what is valued by those who contribute in their urban environments. In so doing, the study demonstrates how online media can support a people-oriented form of urban heritage conservation. This analysis reveals that the following five categories of heritage attribute are remembered by citizens: (1) the built environment and public space, (2) the social fabric and identity, (3) culture and leisure, (4) business and industry, and (5) politics and public order. Moreover, it is found that these attributes are valued because of their social relevance (social value), their connection to the biographies of citizens (experiential value), and their contribution to our understanding of the urban past (historical value).

Dengue is unquestionably one of the biggest health concerns in India and for many other developing countries. Unfortunately, many people have lost their lives because of it. Every year, approximately 390 million dengue infections occur around the world among which 500,000 people are seriously infected and 25,000 people have died annually. Many factors could cause dengue such as temperature, humidity, precipitation, inadequate public health, and many others. In this paper, we are proposing a method to perform predictive analytics on dengue’s dataset using KNN: a machine-learning algorithm. This analysis would help in the prediction of future cases and we could save the lives of many.

Background: Marketing of food supplements in Greece in print media has not been examined and this study is the first attempt to provide a comparative statistical analysis. Methods: Lifestyle magazines that were distributed all over Greece and aimed at women and men were collected in the years 2014 and 2016. Five criteria with their subcriteria were developed and were related to the branding of the food supplements; their quality characteristics; the information given about health concerns; photographs of people who promoted food supplements and to claims of their suitability. Results: It seems that in terms of product branding, women’s magazines were more likely to be targeted. Some quality characteristics such as information about the ingredients of food supplements or information about banned substances were more likely to be seen in women’s magazines in 2016. In 2014 and 2016, not all advertisements provided information about health concerns and among those which informed readers about health concerns, differentiation in target audiences was observed. Photographs that showed people promoting food supplements as well as claims of suitability for various categories of consumers, seem to be gendered in 2014 but this trend was not strong enough in 2016. Conclusion: It can be argued that the marketing of food supplements was aggressive and gendered in 2014 and changed in 2016 with better information on public health but had retained some gendered stereotypes.

This chapter introduces ethical issues that arise in the context of biosecurity: policies and actions intended to prevent the development or emergence, or mitigate the consequences, of serious biological threats. These threats could include deliberate biological weapon attacks (bioterrorism), pandemics, emerging infectious diseases, or major laboratory accidents. The basic values that underpin these public health concerns are first introduced. Ethical issues that arise before, during, and following a biosecurity crisis are then examined, including issues of resource allocation, dual-use research, and the possibility of quarantine. Their resolution requires trade-offs among different ethical values, including utility, fairness, and liberty.
