Zusammenfassung
Climate risk arising from both climate variability and change is heterogeneous across a diverse range of spatial scales. At the global scale climate risk is generally assessed to be more acute in the coastal regions of developing and emerging countries which have significant exposure to climate hazards, but is additionally associated with the specific socio-economic context that exacerbates those hazards (Preston et al., 2006). At the national level, various sectors, ecosystems and regional subpopulations within these countries have been identified as being more or less vulnerable to changing future climatic conditions (IPCC, 2001). However, until today only few studies have attempted to explore the spatial heterogeneity of climate risk at smaller spatial scales, such as on the metropolitan or urban scale (Rosenzweig et al., 2000). As part of the research programme 'Sustainable Development of the Megacities of Tomorrow’ by the German Federal Ministry of Education and Research (BMBF), a suite of projects is being funded in conjunction with other partners to assess climate change risks and possible adaptation and mitigation strategies at the scale of mega-urban regions. These projects are linked through an emphasis on the integration of knowledge about changes in the climate system together with knowledge over the regional context of urban growth centres in which those changes will occur. These projects are focused, on building energyand climate-efficient urban structures to mitigate climate risk and to enable adaptation strategies on the urban scale. The research project ‘Integrative Urban and Environmental Planning for Adaptation Ho Chi Minh City to Climate Change Sustainable Strategies for Climate-Oriented Urban Structures, Energy-Efficient Housing Typologies and Comprehensive Environmental Protection for Megacities of Tomorrow’ emphasises the impacts of climate change and the identification of adaptation strategies for ameliorating those risks, including constraints and barriers on decision making.
