| Abstract | The impacts of climate change are predicted to be unevenly distributed, with many of the greatest challenges to be faced by the mega urban regions situated in the intra-tropical low elevation coastal zones of Southeast Asia. To these regions, which exhibit significant climate related hazard exposure, portfolios are additionally associated with specific development and socio-economic issues that exacerbate this exposure. While on the other hand, climate change can be seen to magnify the inherent development issues. For Vietnam, a country of the Global South, there is broad agreement that if left unaddressed, the effects and consequences of climate change will present significant threats to the achievement of Millennium Development Goals and the countrys sustainable development. More than half of Vietnam's population presently resides in inter-tropical low elevation coastal zones, the majority of which are settled in the two densely populated mega river deltas around, the northern capital city of Hanoi and the red river delta and the southern economic hub of Ho Chi Minh City and the Mekong delta to the south. The city of Ho Chi Minh City (HCMC) is the country's largest and a rapidly emerging megacity, contributes a dominate share to the national GDP. However the concentration of population and economic activity make HCMC particularly vulnerable to fast-paced unsustainable development and the impacts of climate change. These impacts are altering the traditional context of urban land-use planning and are shaping the priorities of sustainability. The environmental dimension of spatial planning in emerging megacities such as HCMC, has become a strong rationale for coordinating spatially well defined adaptation actions and responses and integrating mitigation policies (Storch 2009). This paper describes the initial research results in the development of geographical information system (GIS) based climate change vulnerability and urban sustainability indicators, based upon a common spatial framework using an urban structure type approach for HCMC. The proposed system represents a thematic integrative method where ultimately domain specific GIS applications, analytical models and thematic assessment methods, including climate change resilience and exposure indicators, will be used to generate spatial sector-specific risk and vulnerability analyses. Through the utilisation of planning recommendation maps, the comprehensive aim is to develop, designate, and incorporate climate change mitigation and non-structural adaptation potentials into the urban decision- making and planning processes. The research is envisaged to contribute to and promote an increase in the city's resilience to climate-related vulnerabilities and the sustainability of structures. The main objective of the integrated adaptation planning framework is to advance and disseminate knowledge and inform decision-makers and the general public about the climate change risks, increasing capacities to respond to climatic stress, to implement necessary adaptation measures and to strengthen the sustainable responsive capacity of the urban system. |
