Distribution and habitat selection of wintering birds in urban environments

Habitat selection of wintering land-birds was studied in 31 human settlements in Finland. A total of 26 wintering bird species representing 5155 individuals were observed. Between-year variation (CV_B%) and short-term fluctuation within one winter (CV_W%) in species richness (CV_B=10% CV_W=15%) were low, as were total numbers of birds (CV_B=22% CV_W=24%) and populations of the most common bird species (CV_B=20–40% CV_W=15–47%). The most abundant bird species (e.g., Passer domesticus, Parus major and Pica pica) occurred in most of the study sites. The total densities of omnivorous birds, sedentary birds and bird species that commonly use feeding tables were higher in a heavily urbanized areas than in moderately or less urbanized areas. According to the Canonical Correspondence Analysis, three corvid species populations, P. domesticus and Columba livia domestica were positively related to human population density. Corvus corone cornix and P. domesticus populations correlated positively with the proportion of the built-up areas in the study plots. The omnivorous diet of these species was a possible reason for their success in urban environments. Dendrocopus major, Parus montanus, Parus cristatus, Parus ater and Certhia familiaris were negatively related to the urbanization axis. These species live mainly in coniferous forest habitats and are probably unable to use deciduous-dominated urban parks in winter time. To attract these species, coniferous trees and shrubs should also be used in park management and planning in northern latitudes. Many species, like Pic. pica, Carduelis chloris and Parus caeruleus, were located at an intermediate place on an urban–forest gradient axis. We suppose that these species are the most probable candidates for colonizing or increasing their abundances in European towns and cities in near the future. All of these species use feeding tables, which help them to adapt to urban environments.     

Habitat associations of a raptor community in a mosaic landscape of Central Spain under urban development

The effects of urban sprawl and the associated road network on patterns of land use by diurnal raptors were assessed in a extent mosaic landscape of Sierra de Guadarrama subjected to exurban development (Madrid province; Central Spain), within the buffer area of a planned national park. During three consecutive years, the sightings of raptors per 0.25 km² were analyzed to identify their habitat preferences according to several vegetation types, urban cover and length of paved roads. Species richness increased with the amount of deciduous forests of Pyrenean oak Quercus pyrenaica and parklands of Narrow-leaved Ash Fraxinus angustifolia in lowland areas, while it decreased with cover of urban/suburban areas. Analyzing the three most abundant species separately, urban development had a negative influence on the Common Buzzard Buteo buteo and the Black Kite Milvus migrans, although positively affected the Booted Eagle Hieraaetus pennatus, probably through an increase in the availability of its potential prey within urban areas. This study did not find a negative influence of the road network, either considering total species richness or the three most abundant species separately. The current levels of urban development diminished the suitability of the study area for the raptor community overall (though particular species can be favoured), notably when residential sprawls are established over ash parklands traditionally devoted to cattle grazing.     

From Geddes’ city museum to Farrell’s urban room: past,present, and future at the Newcastle City Futures exhibition

ABSTRACT

Genuine engagement about how best to achieve liveable urban futures should be part of planning’s raison-d’etre but it has a chequered history of delivery. Exhibitions harnessing the communicative power of mixed media and linked to a progressive and responsive programme of focused discussion and debate remain relevant to community consultation and civic engagement. Terry Farrell’s concept of the ‘urban room’ to involve citizens in engaging with the past, present, and future of towns and cities offers a contemporary refreshment of the approach propounded by Patrick Geddes from the early 1900s. The possibilities of creating novel and compelling opportunities for civic discourse in this guise are explored in this review article though the Newcastle City Futures pop-up exhibition and events held in Newcastle upon Tyne, UK in 2014. This event carries lessons for imagining how planners, developers, governments, and community groups may come together to critically and creatively forge future propositions for the urban condition.     

Role of Tourism and Place Identity in the Development of Small Towns in the Western Cape,South Africa

A recent study on the growth potential of towns in the Western Cape evaluated the growth potential of 131 towns qualitatively and quantitatively (Van der Merwe et al., Growth potential of towns in the Western Cape, Cape Town, Department of Environmental Affairs and Planning, 2005). Two of the several outcomes of this extensive study were first to index, rank, and categorize the towns according to their development potential and, second, to use these categories of town profiles to develop an investment typology as prescribed in the National Spatial Development Phramework (NSDP). Compared with the provincial mean, 79 (60%) of the towns score negative (‘low’ and ‘Very Low’) development index values, whereas conversely, 16 (12%) towns register ‘high’ and ‘very high’ growth potential index values. Three of the four towns with a ‘very high’ status on both the quantitative and qualitative development ratings are well-known tourism towns (Stellenbosch, George, and Paarl). In other towns (Hermanus, Knysna, Mossel Bay, and Oudtshoorn) with “high” values for growth potential on both indices, tourism also contributes substantially to their local economic development. The main objective of this paper is to emphasize the special role that tourism plays in the growth and development of small towns in the Western Cape. Unfortunately, in some urban centers, unrealistic expectations abound regarding the role that tourism might fulfill as an economic growth mechanism for a town. Although many of the towns in the province possess the resources and attractions to support tourism development, competition is strong. Other prerequisites (tourism infrastructure, potential investors, appropriate services, and skilled labor) are absent from many Western Cape towns. Some of these towns possess a unique place identity, and it will be wise to preserve these towns to qualitatively enrich the province’s small town heritage that will complement tourism development in general and also contribute to economic growth over the long term.

Municipal Costs and Revenues Resulting From Community Growth: II. Industrial-Residential Communities

Rapid urbanization, a high pace of industrialization, and the demands of Soviet Marxist ideology have confronted Soviet city planners with enormous tasks. These are further complicated by the disadvantageous position of local government units as opposed to industries located in their territory, the manner in which national economic planning sometimes hinders efforts at local planning, and certain weaknesses of the city planning profession in both training and methods. While there is a great and continuing quantitative increase in apartment housing, the existence of the individual house poses special problems for city planners, and the construction of local facilities and services has not kept up with housing. The planner's attack on urban problems has recently focused on two programs: design of residential areas as largely self-contained micro-districts, and the reduction of center-city concentration via the satellite city.     

Towards Post-Anthropocentric Cities: Reconceptualizing Smart Cities to Evade Urban Ecocide

ABSTRACT

This short piece acts as a coda to this journal’s special issue on “Smart Cities and Innovative Technologies.” First, it provides a retrospective view of the origins of the smart city concept. The paper, secondly, presents the most recent perspectives on the new interpretations of the smart city notion. It then provides a commentary on the potential directions for a better reconceptualization of smart cities to evade a most likely urban ecocide. Lastly, the short communication concludes by asking two critical questions: (a) Will urban scholars, planners, designers, and activists be able to convince urban policymakers and the general public of the need for a post-anthropocentric urban turnaround? (b) How do the public, private, and academic sectors along with communities pave the way for post-anthropocentric cities and more-than-human futures?     

Sediment size and deposition characteristics in Malaysian urban concrete drains – a case study of Kuching City

This paper highlights the results of sediment size characteristics and deposition analysis on 24 sediment samples from urban concrete drains in Kuching City. Further sampling from surrounding urban towns outside Kuching City and Penang were done for comparison. Samples were collected randomly from three land-use types (residential, commercial and industrial). Sieve analysis results had shown that most of the total samples collected (51 out of 57) were predominantly sand, followed by gravel; while silt and clay were the minor components. Unimodal characteristics were observed in 46 samples while 11 samples showed bimodal characteristics. Of the total 46 unimodal samples, 39 showed non-uniform distribution with tendency to skew to the right. Due to this, the mode grain size with characteristic diameter d₄₅ is suggested as a much better representative size than the conventional median size d₅₀. Factors affecting sediment deposition characteristics in urban drains are also discussed.     

Capturing the Italian townscape: from the beginnings of Italian landscape photography to the anti-idyllic images of Ivor and Ivy de Wolfe

This paper focusses on the photographic illustrations which appeared in a very odd book published in 1963: The Italian Townscape. Its author, curiously named Ivor de Wolfe on the front cover, was in fact Hubert de Cronin Hastings, a major figure in architectural publishing. The photographs were taken mainly by Ivy de Wolfe (another pseudonym), in reality Hastings's wife, Hazel. Fifty years later, Erdem Erten and Alan Powers, as editors, published a new edition, aimed at the general public. In their brilliant introductory essay the topic of photography is considered with a light touch. In the same period, Robert Elwall had spent time and energy revaluating the images and the photographers. In his article entitled ‘Road show’ (RIBA Journal, June, 2005) and during a speech at the Retrospective Symposium on The Architectural Review's Townscape Campaign (22^nd July, 2011), Elwall discussed the visual approach to urbanism as a hallmark of the Italian planning stance towards historical towns. Images of Sabbioneta, Padua and Loreto were among the examples considered.

The process of touring Italy with a camera after the Townscape debates in the 1950s persuaded Hazel Hastings to suggest an uncommon idea of the Italian cultural landscape, a new appreciation of both historical and contemporary vernacular elements of the built environment, and a tension between the understanding of pedestrian and vehicular urban scales. In introducing some of these themes, my paper will draw on a range of evidence from visual echoes, to shared language, to occasional statements on the subject by Italian photographers and town planners.     

A method for mapping the spatial distribution of <Emphasis Type="Italic">RockFall</Emphasis> computer program analyses results using <Emphasis Type="Italic">ArcGIS</Emphasis> software

Rockfalls are a natural process of cliff and hillside erosion and can be simulated by computer programs. RocFall is a useful and well-known program which produces envelopes of kinetic energy, velocity, bounce height and fall-out distance for a selected profile. However, with this program it is difficult to record the spatial distribution of the envelopes in their exact coordinates in GIS. In this paper, a method and computer code (FallGIS) written by the authors is proposed for mapping the results obtained from RocFall in ArcGIS. As it is both user-friendly (hence quicker) and does not require any new software, it is hoped it will be a useful tool for engineering geologists, urban planners, etc.      

A next step for sustainable urban design in the Netherlands

The Dutch Working Group on Sustainable Urban Development has recently delivered its publication Sustainable Urban Design, The Next Step (Meijer & Dubbeling, 2010). The book (to be referred to here as The Next Step) includes six examples of sustainable urban design and three major essays. The Working Group is a broad group of experts from the Dutch professional societies for urban designers and planners (BNSP) and landscape architects (NVTL). (The working group consists of urban designers, urban planers and landscape architects from the Netherlands.) It seeks to take the thinking and practice of sustainable urban design a step further: from sustainable urban design to sustainable spatial development. This paper explains this next stage which has been developed through a review of the literature, the inputs of the Working Group and the lessons learned from the case studies described in the book. Although the case study projects are sometimes more than 12 years old and are rooted in a specific Dutch societal and spatial context, they provide interesting, even up to date, insights for the planning of sustainable and durable cities. They are also compared to some projects in other European countries.This paper looks at why a renewed approach to sustainable urban design is both necessary and rewarding. It then turns to the renewed approach and putting it into practice. Based upon the case studies, new possibilities for the design of sustainable and durable cities are highlighted.     

‘Mentally,we’re rather country people’ – planssplaining the quest for urbanity in Helsinki,Finland

ABSTRACT

This paper explores the concept of urbanity in a specific context, namely Helsinki, Finland. In a European context, Finland urbanized late. This lies at the heart of the common interpretation that Finland lacks an urban culture and urban lifestyles. Today, however, with the new comprehensive Urban Plan, city planners in Helsinki emphasize a paradigm shift towards urbanity. This paper seeks to understand this changing emphasis in planning by exploring how planners frame and understand urbanity. The paper concludes that within the Nordic welfare context more emphasis is needed to rethink whom urbanity serves and how it resonates with the prevention of segregation that the city also aims at.     

Civic design and national identity: the example of Edwardian Ireland

The field of civic design is a relatively unexplored domain within British cultural, political and planning history, despite its implementation by public authorities and its acknowledged significance to formative town planning.1 S.M. Gaskell, ‘The Suburb Salubrious: Town Planning in Practice’, in British Town Planning: The Formative Years, ed. A. Sutcliffe (Leicester, England: Leicester University Press, 1981), 50. What is more, given the determined moves circa 1900 within a number of British-controlled territories to obtain governmental independence, art was manipulated, on the one hand, to be an authoritative force to help maintain control over native populations and, for those seeking to remove British sovereignty, to express local pride and notions of nationhood. This article examines the design of the Royal College of Science and Government Buildings in Dublin, Ireland. In doing so, it reads British–Irish opposition into the built environment. The aim is to broaden the understanding that historians and planners have as to how cultural, political, artistic and environmental forces interrelated with each other during an age when, significantly, urban planning was being professionalized and diffused across the globe and the understanding of national identity in towns and cities under British jurisdiction was being recast.     

‘Must our cities remain ugly?’ – America's urban crisis and the European city: transatlantic perspectives on urban development, 1945–1970

This article explores the changing modes and mechanisms of the transatlantic dialogue between urban planners from the perspective of US urbanists. During the early post-war period, this dialogue intensified quickly. US planners were involved in their country's broad efforts to provide assistance to and build strong political ties with Western European nations. Accordingly, they assumed the role of tutors vis-à-vis their European peers. Due to urban America's apparent flaws and the success of European planning projects, however, their interest in Europe broadened considerably during the 1950s. Initially, the initiative of individuals remained crucial for the flow of planning information from Europe to the USA, and European immigrants and émigrés helped facilitate transatlantic transfers. Looking at Europe, American planners sought to address the shortcomings of the domestic practice of planning as they perceived them. Europe served as an argumentative tool for US experts who were eager to change the socio-political framework that limited their impact on urban development in their home country. Information about European planning was transmitted through a diverse set of channels and the biographies of many of the experts involved with transatlantic exchange remind us of the complex international planning networks that existed throughout the twentieth century. American planners' interest in Europe remained biased towards specific regions and topics. Nevertheless, US planners negotiated the way in which they brought their limited influence to bear on American urban environments in a transnational context. The framework that supported their integration into international planning discussions became increasingly institutionalized towards the end of the research period.     

Simulation of the urban thermal comfort in a high density tropical city: Analysis of the proposed urban construction rules for Dhaka, Bangladesh

The thermal comfort in urban canyons of a high density city is a very challenging issue for urban planners and designers, especially in hot humid tropical zone. The present study aims to evaluate the effects of a newly promulgated building construction rules in respect of thermal climate for Dhaka, Bangladesh, a region characterized by high density area with tropical climate. Three different urban canyons from three areas were considered which almost represents the whole city. Measurements were carried out to assess the existing thermal climate in the city canyons. Further, three model canyons were configured according to the new rules of ground coverage, floor area ratio (FAR) and site setback. A three-dimensional numerical model with high spatial and temporal resolution was used to investigate the microclimatic changes within the urban environments. Model calculations were run for a typical summer day. The thermal climate was evaluated based on air temperature T _a, surface temperature T _s, relative humidity RH, and wind speed in the existing and model canyons. For thermal comfort assessment the temperature humidity index (THI) was considered in this study. The results showed that the outdoor spaces of the study areas are thermally uncomfortable and the new building construction rules hardly improve the conditions in general. However, THI decreases in a canyon where sky view factor (SVF) decreases in the model canyon than the existing one. In addition, the surface temperature T _s and air temperature T _a do not show the same picture. Furthermore, the wind speed increases in all the model canyons as the site setback allows wind flow uniformly inside the canyons.     

The Value of Cittaslow as an Approach to Local Sustainable Development: A New Zealand Perspective

Cittaslow is an Italian-inspired global network of towns that collectively resist globalization and mainstream corporate-centred development through planning and urban design that prioritize each town's local, unique and historic resources. Internationally, Cittaslow's regulations-for-action approach has assisted towns to more effectively implement sustainable development principles. This paper presents research from three New Zealand case-study towns, to assess the potential application of Cittaslow principles to aid sustainable development and economic growth in small towns. The findings revealed that planners and community members generally perceived Cittaslow as a superfluous ‘brand’ that imposed additional unnecessary regulations and an approach that lacked general community support.     

Catch Me if You Can: Workplace Mobility and Big Data

ABSTRACT

A growing number of workers, particularly in the knowledge and service sectors, can perform their work at multiple locations, and it is decreasingly realistic to assume, as researchers and planners have traditionally done, that employment in cities occurs in fixed locations. This suggests that census data or establishment registries do not fully capture where economic activity takes place. Given the role that ICTs play in enabling daytime workplace mobility, and given that they generate substantial amounts of real-time, geolocated data, we ask whether these Big Data can shed light upon the trajectories of mobile workers at the urban scale.     

A Data-Driven Approach to Exploring Future Land Use and Transport Scenarios: The Online What If? Tool

ABSTRACT

In an era of rapid urbanization, there is a need for data-driven tools to guide long-term strategic planning. Online What If? (OWI) is a planning support system (PSS) that helps inform strategic planners about the impact of population growth and other socioeconomic factors will have on the future growth of cities. This research presents its application in metropolitan Perth with a two-part case study, demonstrating a first comprehensive application of the tool. First, OWI tests five scenarios for urban growth through the year 2050, allocating residential land use. Next, OWI alters land use allocations to align residential development with high frequency public transit, while also allocating commercial land use to support higher residential densities. Together, these data-driven scenarios inform city planners and policy makers in guiding the long-term, sustainable growth of Perth. The paper concludes with a review of OWI’s strengths, weaknesses and possibilities for continual development.

Planning for deep-rooted problems: What can we learn from aligning complex systems and wicked problems?

An earlier generation of planners turned to Rittel & Webber’s 1973 Rittel, H. W. J., & Webber, M. M. (1973). Dilemmas in a general theory of planning. Policy Sciences, 4, 155–169. doi:10.1007/BF01405730[Crossref], [Web of Science ®] , [Google Scholar] conception of “wicked problems” to explain why conventional scientific approaches failed to solve problems of pluralistic urban societies. More recently, “complex systems” analysis has attracted planners as an innovative approach to understanding metropolitan dynamics and its social and environmental impacts. Given the renewed scholarly interest in wicked problems, we asked: how can planners use the complex systems approach to tackle wicked problems? We re-evaluate Rittel and Webber’s arguments through the lens of complex systems, which provide a novel way to redefine wicked problems and engage their otherwise intractable, zero-sum impasses. The complex systems framework acknowledges and builds an understanding around the factors that give rise to wicked problems: interaction, heterogeneity, feedback, neighbourhood effects, and collective interest traps. This affinity allows complex systems tools to engage wicked problems more explicitly and identify local or distributed interventions. This strategy aligns more closely with the nature of urban crises and social problems than the post-war scientific methodologies about which Rittel and Webber had grown increasingly sceptical. Despite this potential, planners have only belatedly and hesitantly engaged in complex systems analysis. The barriers are both methodological and theoretical, requiring creative, iterative problem framing. Complex systems thinking cannot “solve” or “tame” wicked problems. Instead, complex systems first characterize the nature of the wicked problems and explore plausible pathways that cannot always be anticipated and visualized without simulations. The intersection of wicked problems and complex systems presents a fertile domain to rethink our understanding of persistent social and environmental problems, to mediate the manifold conflicts over land and natural resources, and thus to restructure our planning approaches to such problems.     

Interpreting reinterpretation: the 13th conference of the European Association for Urban History,Helsinki, 24–28 August 2016

A sunny Helsinki was the backdrop for the 13th biannual conference of the European Association for Urban History (EAUH). The EAUH was established in 1989 with the aim to create a common platform to historians, geographers, sociologists, planners, and other scholars working with a multidisciplinary approach on urban history in different time periods. The first EAUH conference took place in Amsterdam in 1992 and the next one will take place in Rome during 2018 (for further information about EAUH, please visit the website: http://www.eauh.eu/). The ambitious theme of the 13th conference was Reinterpreting Cities. For planning historians, this theme held ample promise on programmatic, methodological, and theoretical levels. With 592 participants, 44 main sessions, and 30 specialist sessions, we decided to look at the conference through a specific lens. Based on a selection of relevant panels, therefore, we formulated two questions: first, how can a reinterpretation of cities lead to new theories on the city and connect to existing theories in other disciplines? And second, how can a reinterpretation of urban history connect to the ‘real world’, for example, planning practices? This conference report explores the ways in which this conference actually reinterpreted the city, in particular, how it connected to the spatial dimension and planning history.
