Next Phase
Dissemination Workshop for Mapping Philippine Vulnerability to
Environmental Disasters
Klima Climate Change Center
8 July 2005

Purpose of National-Scale Risk Mapping:
• Identify priority areas for localized risk
mapping
• Identify trends and themes across
categories that may potentially be
correlated
 DIRECTIONS FOR FURTHER STUDIES!

Summary: Geophysical Disaster Risks
Is there any other factor
contributing towards the

LAND USE MAP vs. DISASTER RISK MAPS
What risk do climate and weather-related
disasters pose on our livelihood?
LAND USE MAP vs. DISASTER RISK MAPS
Needed: a more detailed study of how
geophysical disturbances and slopes
affect or affected by plantations,
forests and other sources of livelihood
GVA MAPS vs. DISASTER RISK MAPS
An Alternative Approach to Quantifying Risk to Livelihood
Together with maps of ecological
resources, can a correlation be
established between GVA and
disaster risk?
URBAN CENTERS MAP vs. DISASTER RISK MAPS
To what extent are the resources of urban
centers able to reduce risk? How can we
quantify the ability of urban centers to respond
to, adapt to or mitigate climate disasters?
URBAN CENTERS MAP vs. DISASTER RISK MAPS
What effect do urban centers have on
geophysical disaster risk?
Urban Centers in High Geophysical Disaster Risk Areas
• ADVANTAGES
• DISADVANTAGES
– Resources
– Response
– Collateral damage
 Reduces disaster risk
 Compounds the
disaster risk!
• E.g. collapsing
buildings, ground
liquefaction
ECOLOGICAL PRIORITIES MAP vs. CLIMATE DISASTER MAPS
How will the projected climate change
potentially affect the country’s ecosystems,
particularly in areas of high marine and
terrestrial priority?
ECOLOGICAL PRIORITIES MAP vs. CLIMATE DISASTER MAPS
Will socio-economic pressures compound
the effect of climate change? How will
changes in population and land use affect
priority rankings?
GROUNDWATER AVAILABILITY MAPS and the RISK to EL NIÑO
SLOPE and FOREST COVER vs. LANDSLIDES
MINES, RIVER BASINS and CRITICAL WATERSHEDS
MAPPING ECOLOGICAL DISASTER RISKS: What is the
possibility of water contamination due to mining
activities? This may be compounded by geophysical,
climate and weather-related disasters.
The Next Phase of Risk Mapping:
1. Review and reformulate framework for
determining risk, R = HEV:
–
–
–
–
Consider possible collateral hazards
Consider livelihood as well as lives exposed
Consider multiple vulnerabilities
Consider efforts at adaptation, prevention and
mitigation that may reduce risk
2. Determine the effect of the presence of urban
centers, and quantify access to urban centers
using maps of location, slope and
transportation.
3. Create ecological disaster risk maps.
4. Find correlations among the
anthropogenic, ecological and disaster
risk maps.
E.g. ecological maps with climate disasters and
possible climate change, population growth and land
use change
5. Conduct localized disaster risk mapping in
high-priority areas.
