"MICRO-ZONING AND RISK MAPPING FOR
PLANNING FOR DISASTER MANAGEMENT
For sake of clearer understanding the terms as they
are defined and accepted by the UN bodies need to
be mentioned here.
1. Disaster Management authority: the body of
policy and administrative decisions and operational
activities, which pertain to the various stages of a
disaster at all levels.
2. Risk: risk is the expected losses of lives, persons
injured, damage to property and disruption of
economic activity due to a particular hazard.
Risk is the product of hazard and vulnerability.
3. Vulnerability: Vulnerability is an essential part of
hazards and risk research and refers to the
susceptibility of communities or regions.
4. Mitigation: All actions taken prior to the
occurrence of a disaster including preparedness
and long term risk reduction measures.
5. Preparedness: Preparedness consists of
activities designed to minimize loss of life and
damage, organize the temporary removal of people
and property from a threatened location, and
facilitate timely and effective rescue, relief and
2. Mitigation and Preparedness
DMP is a analogous to preventive health care.
whilst most efforts are directed towards post
disaster relief, reconstruction and rehabilitation
disaster mitigation involves implementing long term
risk deduction measures. measures range from
large scale flood protection measures (eg.
Bangladesh, China) to income generation
programmes diversifying livelihood, grain
Categorized as development project, but can serve
more than one aim if planned accordingly.
2.1 Disaster Mitigation includes
Policy eg. Land regulation, low income housing
schemes, environmental regulation, national food
grain securities policies, etc.
Training eg. Policy makers, staffs, etc.
Identification of vulnerable groups
Public awareness rising eg. Amongst
retailers, community members, civic groups, etc.
Information system eg. For
monitoring, documentation, dissemination
discipline(construction, architecture, urban
planning, agriculture, etc.)
2.2 Preparedness Measures
Early warning systems
Life safeguarding eg. Hurricanes shelters
Resources and emergency kits in anticipation of
Maintain emergency rosters and evacuation plan
Emergency information and communication
Public education and preparedness campaigns
3.1 Measure Vulnerability
Two innovative approaches are introduced here.
Cutter et al. (2003) have concentrated on
measuring social vulnerability, which is an integral
part of the Hazards-of-place model.
includes both social inequalities and place
This definition includes both the social and
economic vulnerability dimensions of the Hazard’s
A second interesting model is UNDP’s Disaster
Risk Index (DRI)(2004)
which measures & compares the physical
exposure to hazards, vulnerability and risk
Here, physical exposure refers to the number of
people located in areas where hazardous events
occur combined with the frequency of hazard
3.2 What is Risk Mapping?
Risk mapping is the process of establishing the
spatial and temporal extent of risk (Probability &
Risk mapping requires combining maps of
hazards, exposure, and vulnerability
The results of risk mapping are usually presented
in the form of maps that show the magnitude and
nature of the risk
3.6 Exposure Mapping
1. Population in terms of its poverty or vulnerability
2. Buildings in terms of their structure type &
functionality (i.e. residential, commercial,
industrial, and public)
3. Livelihoods, i.e. livestock, crops, industries (the
number, location & extent of exposure)
4. Critical facilities, i.e. healthcare, educational
institutions (university, college, school, etc.),
warehouses, banks, police stations, fire stations,
5. Infrastructures, i.e. roads, bridges, airports, ports,
railways, dams, telecommunication network,
power supply, etc.
