Abstract :

South Asia region (SAR) is one of the hotspots of almost all disasters in the world because of its complex geo–tectonic settings; bigger flood plain basins, and long coastal belts, which is being severely impacted by climate change induced disaster events. In this study a through analyses of several factors of geophysical, hydro–meteorological and climate change induced disaster events has been made to understand what suggestive steps can be taken for safer and sustainable urban risk resilient model for SAR. It is observed that the city populace of SAR get exposed to the inland flooding, coastal flooding, heat and cold, forest fire, water shortage due to drought, air pollution, mud slides, landslides, wind storm, cyclones etc. With the global warming, the propensity of the event arising out of these hazards is getting changed with the change in the time interval and becoming extreme and intensive in nature. We attempted to explain how the model is significant for planner to understand the trend of the new urban settlement coming up in different geographical locations, for giving them different treatment to mitigate the ill–effect of climate change on the citizen of these places during planning itself. The trend of Urbanization as a result of change in the GDP structure and migration of the rural population to the urban area in search of better livelihood is going to stay in the countries of South Asia region. The growth of new urban areas and addition with expansion of the existing cities, however, is under stress due to supply of urban amenities and socio–economic urban infrastructure that are not getting match with the rising demand. In this study, we suggested three step comprehensive urban risk resilient models for sustainability, which take care of: urban disaster management response Cycle (UDMRC); sustainable and risk resilient urban development mechanism; and risk resilient urban agglomerate (RRUA) setup associated with urban risk resilient wheel with ten different spokes.
