Frequent and unprecedented mass disasters have occurred across the globe. In the past,
natural disasters such as floods and droughts were the norm, but now diverse calamities
such as heat waves, heavy snows, strong winds, and rising sea levels occur frequently.
Disasters resulting from climate change involve uncertainties about when they will
occur. Therefore, response measures should be prepared in advance. In addition, it is
also difficult to expect which places will experience disasters due to climate change.
Disasters may occur in vulnerable places in addition to already affected areas. Therefore,
preventive measures against the consequences of climate change should be developed
in potentially affected areas such as areas vulnerable to heat waves, regions with high
impermeability, areas with high density populations, etc.
This report is composed of two parts. In the first part, urban disaster prevention
strategy and policy in Korea is introduced. And, in the second part, the case study of
disaster vulnerability analysis and its implications are described.
The primary causes of disaster related incidents are the negative consequences of
localized heavy rains, typhoons and heavy snows that are triggered by climate change.
The main factors that aggravate disasters are: low-lying areas, areas surrounding steep
slopes, utilization & development of areas with inadequate disaster prevention strategies
such as densely populated areas with vulnerabilities to disasters, reckless land use and
building arrangements, and the lack of rainwater detention systems and infiltration
systems.
For cities to better adapt and respond to heavy rain disasters caused by climate change
(larger and more routine), a Comprehensive Disaster Prevention Safety Net System
needs to be constructed where all the constituents of a city respond in harmony to an
impending disaster. A Comprehensive Disaster Prevention Safety Net System denotes a
system that shares disaster risks in connection with urban land use, urban infrastructure
(i.e., park, green belt), complexes (i.e., housing complex), buildings, and citizens in
addition to a traditional disaster prevention system (i.e., rivers, sewers, pumping
stations).
PSR, a modern version of the past spatial drainage system (valley - small pond ..
village(natural & man-made waterways) - large pond - river), denotes a multi-layered
urban disaster prevention strategy that delays runoff of rainwater or stores it ‘’layer by
layer”, taking into account the characteristics of the areas that fall under the scope of a
disaster’s direct and indirect influence....
