Ho Chi Minh City (HCMC), economic center and most populous city of Vietnam faces a strong structural change since its market liberalization in the late 1980s. Big challenges occur in the form of uncontrolled urban sprawl due to rapid population growth with encroachment of agricultural land, which leads to environmental and climatic issues like urban heat island effects, air pollution and flooding events. Remote Sensing and Geographic Information Systems (GIS) provide new computer-based techno...

Measures and strategies for climate adaptation and mitigation on the local level have become more or less obligatory. However, local governments face epistemic and organisational uncertainties. New agencies are created, new intra- and inter-organisational relationships are established and new competencies are requested. We argue that knowledge orders are of utmost importance for the institutionalisation of climate policies. We compare knowledge generation, the production of evidence and frami...

„Energieeffizienz in benachteiligten Quartieren“. Der Titel öffnet den Blick auf Quartiere mit problematischen Rahmenbedingungen. Auf benachteiligte Quartiere, die aufgrund ihres hohen energetischen Einsparpotenzials für die Erreichung der übergeordneten Klimaschutzziele von besonderem Interesse sind, in denen oft jedoch aufgrund demografischer, sozialer und ökonomischer Voraussetzungen keine energetischen Sanierungsmaßnahmen im privaten Wohngebäudebestand umgesetzt werden. Das Forschungsi...

KURZFASSUNG Unter dem Begriff Klimawandel wird die menschengemachte Veränderung des globalen Klimas verstanden. Der Klimawandel äußert sich durch langfristige, irreversible Veränderungen von Klimaparametern wie Temperatur und Niederschlag und führt zu einem häufigeren Auftreten von extremen Wetterereignissen (vgl. DWD 2014a). Die regional unterschiedlich ausgeprägten Auswirkungen des Klimawandels haben gemein, dass sie auf anthropogene Raumnutzungen treffen, die diesen Auswirkungen gegenüber...

Although urban areas cover a very small fraction of the world’s land surface, rapid urban expansion has significantly changed the landscape and formed immense environmental and social impacts. These effects are principally important in rapidly changing areas such as urban settlements in developing countries. Over the last decades, several studies have focused on the field of urban expansion. However, the implications of this rapid urban expansion have not been sufficiently analyzed. They pre...

Green and open spaces are important components of green infrastructure. They offer a range of different ecosystem services society benefits from. Due to ongoing urbanisation and densification processes many urban and peri-urban green and open spaces disappear or degrade in quantity and quality, with negative impact on their ecosystems. The decline of the ecological functions of nature and landscape also weakens their social and economic merits, which are especially important for society. Henc...

This thesis studies the themes of land use and social rights with special reference to the urban village, which is a special phenomenon in city-expansion in contemporary China. By conducting an extensive review of literatures on urban villages and boundary studies, the author studies land use and social rights from the perspective of boundary. The author also emphasizes boundary-making as a social construction process, which involves different stakeholders in this “game”. Further, the author ...

This dissertation provides a comprehensive picture of urban shrinkage and its relevance within contemporary urbanization processes in Europe. The thesis demonstrates that shrinking cities are neither a one-dimensional phenomenon nor a side-effect of growth but a unique path of urban development. Thereby, the dissertation address a complex topic that intersects urban geography, demography, planning and spatial modelling thus underlying the interdisciplinary character of this work. Urban shri...

Climate change induces the probability of occurring natural disasters; e.g. floods, Sea Level Rise, Green House Gases. Flood is considered one of the most dangerous phenomena that tremendously and dramatically threatening the human being and environment worldwide. Rapid urban growth, demographic explosion, and unplanned land uses have exacerbated the problem of urban flooding, particularly in the cities of China. In addition to that, the concept of flood risk management and adaptation measure...

Vu Gia- Thu Bon River Basin, located in the Central Coastal Zone of Viet Nam faces water shortage problems. This is expected to be further exacerbated in the future as a result of climate change. Previous attempts in addressing water shortage in the area followed a traditional top-down, predict-then-act approach. In such an approach, General Circulation Model outputs simulating future climate conditions are downscaled then adaptation measures proposed. This approach could produce optimal adap...

Es ist empirisch gut belegt, dass städtische Entwicklungen einen Einfluss auf Gesundheit haben. Gesundheitsförderung muss im Sinne des „Health in all Policies“-Ansatzes daher auch ein Handlungsfeld der Aktivitäten von Stadtentwicklung sein. Die Verfahren und Instrumente der Stadtplanung schöpfen jedoch nicht ihr volles Potenzial aus, um Gesundheitsbelange in Planungsprozessen zu berücksichtigen. Aktuelle Publikationen zum Thema gehen weiterhin von zu überwindenden Defiziten in der gesundheits...

Im Kontext von nachhaltiger Stadtentwicklung ist die Schaffung gesunder Wohn- und Arbeitsverhältnisse ein wichtiges Ziel. Im Sinne des Subsidiaritätsprinzips kommt dabei der lokalen Ebene eine wichtige Rolle bei der Implementation übergeordneter politischer Ziele und den daraus resultieren Rechtsvorschriften zu. In der kommunalen Planung stellt der gewerbliche Immissionsschutz historisch ein zentrales Aufgabenfeld dar, denn mit der Ausübung von Gewerbe im städtischen Raum sind potenziell viel...

Green spaces and urban space are an unlikely couple. In the urban context, green areas are subordinated to functional aspects of the city like infrastructure and housing. Nevertheless, there seems to be a consensus about the relevance of green spaces for wellbeing. By stressing this relevance, central traits of urban green often stay unquestioned. In what instance does urban green get relevant or not in urban everyday life? The research investigates the everyday perception and appropriation o...

Over the past decades, mountainous areas and river valleys in Europe have frequently experienced floods and landslides. In order to reduce negative impacts, society is required to implement risk prevention measures. Decisions on where and how to develop space can significantly influence the vulnerability towards disasters. Specific risk reduction strategies and measures can be implemented at regional and local scales through spatial planning decisions. The ability to make appropriate decision...

It is expected that the changing temperatures and rising sea levels caused through global climate change will result in an aggravation of disaster risks (e.g. from heat stress, storms, flooding, landslides, air pollution, drought and water scarcity), particularly in urban areas (IPCC, 2014). This trend is exaggerated by the continuing trend of urbanization, which is projected to result in 66% of the people worldwide to live in cities in 2050 (United Nations, Department of Economic and Social ...

Although a significant number of trips in cities of developing counties are made on foot, especially in Sub Sahara Africa, the pedestrian environment has largely been neglected by most city authorities. Faced with high rates of motorization and the need to accommodate the growing requirements in increasingly urbanizing population; cities of the developing world are more preoccupied with motorised transport systems such as building arterial streets, Rapid Bus Transport systems (BRTs), fly over...
