Urban Heat Island (UHI) is considered as one of the major problems in the 21st century posed to human beings as a result of urbanization and industrialization of human civilization. The large amount of heat generated from urban structures, as they consume and re-radiate solar radiations, and from the anthropogenic heat sources are the main causes of UHI. The two heat sources increase the temperatures of an urban area as compared to its surroundings, which is known as Urban Heat Island Intensity (UHII). The problem is even worse in cities or metropolises with large population and extensive economic activities. The estimated three billion people living in the urban areas in the world are directly exposed to the problem, which will be increased significantly in the near future. Due to the severity of the problem, vast research effort has been dedicated and a wide range of literature is available for the subject. The literature available in this area includes the latest research approaches, concepts, methodologies, latest investigation tools and mitigation measures. This study was carried out to review and summarize this research area through an investigation of the most important feature of UHI. It was concluded that the heat re-radiated by the urban structures plays the most important role which should be investigated in details to study urban heating especially the UHI. It was also concluded that the future research should be focused on design and planning parameters for reducing the effects of urban heat island and ultimately living in a better environment.
In this research, urban public participation is a collaborative decision-making process between residents, businesses, experts, public officials, and other stakeholders. When processes are not attuned with the local context (participant lifestyles, needs, interests, and capacities) misalignments between process and context arise around living conditions and personal circumstances, stakeholder trust, civic engagement, collaborative capacity, and sustainability literacy, among others.
This dissertation asks (1) what challenges arise when the public participation process does not match the local context, (2) what are key elements of public participation processes that are aligned with the local context, (3) what are ways to design public participation that align with specific local contexts, and (4) what societal qualities and conditions are necessary for meaningful participatory processes?
These questions are answered through four interrelated studies. Study 1 analyzes the current state of the problem by reviewing public participation processes and categorizing common misalignments with the local context. Study 2 envisions a future in which the problem is solved by identifying the features of well-aligned processes. Studies 3 and 4 test interventions for achieving the vision.
This dissertation presents a framework for analyzing the local context in urban development projects and designing public participation processes to meet this context. This work envisions public participation processes aligned with their local context, and it presents directives for designing deliberative decision-making processes for sustainable urban development. The dissertation applies a systems perspective to the social process of public participation, and it provides empirical support for theoretical debates on public participation while creating actionable knowledge for planners and practitioners.
The dissertation consists of three studies. Study 1 uses a case study approach to investigate existing sustainability program selection processes in three cities: Avondale, USA; Almere, the Netherlands; and Freiburg, Germany. These cities all express commitment to sustainability but have varying degrees of sustainable development experience, accomplishment, and recognition. Study 2 develops a program selection framework for urban sustainable transformation drawing extensively from the literature on sustainability assessment and related fields, and on participatory input from municipal practitioners in Avondale and Almere. Study 3 assesses the usefulness of the framework in a dual pilot study. Participatory workshops were conducted in which the framework was applied to real-world situations: (i) with the city’s sustainability working group in Avondale; and (ii) with a local energy cooperative in Almere.
Overall, findings suggest cities are not significantly adapting program selection processes in response to the challenges of sustainability. Processes are often haphazard, opportunistic, driven elite actors, and weakly aligned with sustainability principles and goals, which results in selected programs being more incremental than transformational. The proposed framework appears effective at opening up the range of program options considered, stimulating constructive deliberation among participants, and promoting higher order learning. The framework has potential for nudging program selection towards transformational outcomes and more deeply embedding sustainability within institutional culture.
