Production of housing in London is driven by three factors: a housing crisis that requires the construction of more than 1.6 million homes by 2025, a model of social housing production mainly delivered through private developers’ contributions, and a metropolitan governance structure through which housing targets are allocated to municipalities with highly unequal pressures, being inner London boroughs the ones with the highest targets to meet. In the context of a non-prescriptive and liberalised planning system, this threefold scenario has resulted in the construction of unprecedented residential landscapes, dominated by high-density and high-rise buildings. Tower Hamlets Council is at the forefront of this challenge both in the UK and Europe and is trying to develop planning tools to shape them. This article discusses three innovative supplementary planning documents (SPDs) produced by the policy team that have had unequal success in shaping different aspects of this form of development: the South Quay Masterplan SPD, the High Density Living SPD, and the soon-to-be-adopted Tall Building SPD. A comparative analysis of these planning documents and the perception of urban planners working at different stages of the planning process on the effectiveness and limitations of these SPDs in shaping vertical neighbourhoods shed light on the key factors influencing the role municipal planning can have in delivering a built environment that supports residents’ quality of life. By doing so, this case study illustrates the limitations of municipal planning and planners in local government, pointing to more structural and strategic issues of metropolitan governance.

Based on the critical stance of citizens towards urban planning, growing attention has been directed towards new forms of citizen participation. A key expectation is that advanced digital technologies will reconnect citizens and decision makers and enhance trust in planning. However, empirical evidence suggests participation by itself does not foster trust, and many scholars refer to a general weakness of these initiatives to deliver the expected outcomes. Considering that trust is reciprocal, this article will switch focus and concentrate on planners’ attitudes towards citizens. Do urban planners generally think that citizens are trustworthy? Even though studies show that public officials are more trusting than people in general, it is possible that they do not trust citizens when interacting with government. However, empirical evidence is scarce. While there is plenty of research on citizens’ trust in government, public officials trust in citizens has received little scholarly attention. To address this gap, we will draw on a survey targeted to a representative sample of public managers in Swedish local government (N = 1430). First, urban planners will be compared with other public officials when it comes to their level of trust toward citizens’ ability, integrity and benevolence. In order to understand variations in trust, a set of institutional factors will thereafter be tested, along with more commonly used individual factors. In light of the empirical findings, the final section of the article returns to the idea of e-participation as a trust-building strategy. What would make planners trust the citizens in participatory urban planning?

The case has been made in reports of the Intergovernmental Panel on Climate Change for the crucial role of the built environment in mitigating the worst excesses of a warming global climate. Urban planners are essential actors in delivering a sustainable built environment. Alongside macro influences such as policy, practices in urban planning are influenced by underlying mechanisms at the level of the individual. Adopting a Bhaskarian critical realist approach, in this study we examined enabling conditions of sustainability practices. Semi-structured interviews were conducted with 19 planners in England with at least seven years’ experience. The analysis found evidence from the planners’ experience of tensions between the three strands of sustainability, and of practices which could be understood from theoretical perspectives of collaboration/consensus, dissensus and pursuit of specific outcomes. A professional commitment towards a better environment appeared to be a generative mechanism for sustainability practices and underlying conditions included professional identity, identity as a public sector worker, organisational and team identities, and personal commitment. Constraining conditions were found to include stakeholder and political pressure and weak policy. The findings suggest points of leverage for the professional body, local authorities and planners themselves, in order to strengthen sustainability practices and potentially lead to transformation.

Ecological considerations should be an integral part of the decision-making processes of urban planners. Specifically, ecological aspects used in urban ecology, such as green infrastructure and ecosystem services, are substantiated by literature as strategies for improving quality of life, human health, and well-being. Studies dealing with such concepts in the Global South recently gained interest; however, these lack empirical evidence on the integration thereof in mainstream South African urban planning practice. This article conducts a preliminary investigation into the knowledge of ecological aspects of a sample of South African urban planners and their willingness to implement ecological aspects in urban planning practice. The new environmental paradigm scale is employed to determine the environmental worldview (ecocentric or anthropocentric) among respondent and how this relates to their knowledge of ecological aspects. The initial research sample consisted of a total of 283 questionnaires distributed. Although findings of this article are based on a low response rate (15%) of 42 documented responses, it did not affect the validity of the data collected in this context. The initial findings indicated that the environmental worldview of the sample of planners is only one factor influencing their perspective on incorporating ecological considerations. Low to moderate knowledge and awareness regarding ecological aspects such as ecosystem services, green infrastructure, and multi-functionality are argued to be main factors preventing integration in urban planning practice. Findings emphasize the need for context-based implementation strategies and broad recommendations are made for the planning profession as a point of departure to introduce or ingrain ecological considerations.

The purpose of this study is to uncover the most prominent challenges that urban planners face when tackling sustainable practices in developing countries. The time frame was set to after the 2012 Rio +20 global summit. Therefore, only articles that were produced from 1 January 2013 till 31 March 2019 were included, as they would have adhered to the contributions and protocols set forth at the largest UN Earth Summit conference. In this study, a review of the sustainable urban planning challenges was conducted. The challenges are then grouped into topics that align with the theme of the type of challenge. Finally, the challenges are analysed to identify the most well-known and disruptive challenges that restrict urban planners in developing countries.

In this study, we evaluate urban agriculture trends in 55 cities in the Southern United States. Our research is important for three reasons. First, as the geographic scope of urban agriculture research is limited mostly to Northeast and West Coast cities, we focus on the South, the fastest-growing U.S. Census region. Second, despite rapid growth, this region has also experienced the highest rate of poverty and food insecurity. Third, we surveyed urban planners who regulate and monitor urban agriculture sites, develop urban agriculture policies and programs, and advise local decision-makers. The study documents Southern urban agriculture changes between 2000 and 2010. It also considers types of projects, implementation barriers, and strategies used to promote urban agriculture. A survey questionnaire was mailed to planning offi­cials in 153 Southern cities; 55 cities responded. Among respondents, 87% reported the existence of urban agriculture in their jurisdiction. Most Southern cities reporting urban agriculture experi­enced urban agriculture growth (69%), 21% reported decline, and 10% did not report a change. The most common projects included neighbor­hood gardens, school gardens, and community supported and entrepreneurial agriculture. Irrespec­tive of urban agriculture growth or decline, the responding cities relied on the same types of regul­atory and policy approaches. Only cities reporting growth in urban agriculture implemented programs to promote urban agricul­ture, including land acqui­sition, trusts, and inter­jurisdictional coordination. Land conversion and lack of economic sustaina­bility were cited as main barriers to urban agricul­ture. The findings suggest the need to further explore the impact of external factors on the effec­tiveness of urban agriculture regulations, policies and programs, and solutions to urban agriculture barriers.

Paul-Henry Chombart de Lauwe has now been forgotten in the french urban sociology. However, between 1950 and 1975, at a time of great upheaval in France, he enjoyed recognition for being both an intellectual and an expert in urban issues. Leader of a large research team, Chombart combined fundamental research with applied studies. He worked for the ethical reflection to be a central issue regarding the role of humans in contemporary cities as well as pragmatic advice for urban planners. He was first concerned with the working-class' lot, but then he tried with the people to pave a way to local democracy.

In the second part of this thesis effects of climate adaptation measures on thermal comfort were studied. With a better understanding of the effectiveness the ‘best’ solution in relation to thermal comfort can be selected. Nevertheless, this might not be the most appropriate solution considering the site specific conditions. What considerations determine a particular design choice? This question frames the research by design studies in the third part of this thesis. It is particularly interesting for this research to know why a designer decides to apply, or not to apply, climate adaptation measures when is asked to develop an integrated design with the utmost account of thermal comfort at street level. With more insight in the approach of designers to the theme a design method can be developed that fits to the actual role of urban microclimate in the design and planning process. And gives an indication of what output from this research can be of importance to strengthen the role of the theme. In this chapter a group of designers and planners is asked to give insight in their way of thinking through a questionnaire and an in-depth-interview. The results enables answering the sub-question: What is the role of the urban microclimate in the design process according to urban designers and planners?

Urban design professionals are key actors in early design phases and have the possibility to influence urban development and direct it in a more sustainable direction. Therefore, gender differences in environmental perspectives among urban design professionals may have a marked effect on urban development and the environment. This study identified gender differences in environment-related attitudes among urban design professionals involved in the international architectural competition ‘A New City Centre for Kiruna’ in northern Sweden. Participants’ self-rated possibility to influence environmental aspects was higher for males than for females. Conversely, the importance placed on environmental aspects had higher ratings among females, although the differences regarding the rating of personal responsibility were small. The gap between the participants’ self-rated belief in their ability to influence and rated importance of environmental aspects was larger among female participants. Females placed great importance on environmental aspects even though they felt that their possibility to influence these was rather low. Conversely, male participants felt that they had the greatest possibility to influence, although some males rated the importance of environmental aspects thelowest. The gender differences identified are important from an equality and environmental perspective as they may influence pro-environmental behavior among urban design professionals and ultimately influence the environmental performance of the built environment.

Agent-based models have recently been proposed as potential tools to support urban planning due to their capacity to simulate complex behaviors. The complexity of the urban development process arises from strong interactions between various components driven by different agents. AMEBA (agent-based model for the evolution of urban areas) is a prototype of an exploratory, spatial, agent-based model that considers the main agents involved in the urban development process (urban planners, developers, and the population). The prototype consists of three submodels (one for each agent) that have been developed independently and present the same structure. However, the first two are based on a land use allocation technique, and the last one, as well as their integration, on an agent-based model approach. This paper describes the conceptualization and performance of the submodels that represent urban planners and developers, who are the agents responsible for officially launching expansion and defining the spatial allocation of urban land. The prototype was tested in the Corredor del Henares (an urban–industrial area in the Region of Madrid, Spain), but is sufficiently flexible to be adapted to other study areas and generate different future urban growth contexts. The results demonstrate that this combination of agents can be used to explore various policy-relevant research questions, including urban system interactions in adverse political and socioeconomic scenarios.

The discussion about the national economic development theme, ocusing its importance for the knowledge of the projects of lhe future in fight in which deals wilh the definition of lhe great paths to be followed by the Brazilian society, according lo two analytical ways: its historic-structural perspective and its national scalar delimitation. In second place, the article examines, from a left’s version, its main problems, adding in this poini some analytical advances (in this moment critics from lhe progressist urban planners are excluded). In third place, the critics elaborated by lhe progressist planners that, 1 inally, are in agreement with the ones made by the intellectuals, that 1 denominate neodevelopmentists, are considered. At last, three analytical movements are proceeded: the critic of the mentioned intellectuals to urban progressist planners; lhe critic of the progressist planners’ interaction with the liberal economists; and the need for this alliance’s break, being substituted by lhe ‘creation of a way’ that approximates the urban progressist planners and the inteliectual neodevelopmentists.
