The pace of urbanization in the developing world is led by Asia. Over the next 25 years, Asia's urban population will grow by around 70% to more than 2.6 billion people. An additional billion people will have urban habitats (ADB, 2006). The "Hyogo Framework for Action 2005-2015: Building the Resilience of Nations and communities to disasters" (HFA) was adopted at the UN World Conference on Disaster Reduction (January 2005, Kobe, Japan). The HFA specifies that disaster risk is compounded by increasing vulnerabilities related to various elements including unplanned urbanization. Across the HFA, important elements on urban risk reduction are mentioned as one of crucial areas of work to implement the HFA. In particular incorporating disaster risk reduction into urban planning is specified to reduce the underlying risk factors (Priority 4).
