IMPORTANT FINDINGS ACROSS CATEGORIES:
Potential Studies for the Next Phase
Center for Environmental GeomaticsClimate Studies Division
Manila Observatory
Dissemination Workshop for Mapping Philippine Vulnerability to Environmental Disasters
Klima Climate Change Center8 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
occurrenceof shallow landslides in the Bukidnon and Lanao

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 MAPSAn 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– Resources– Response
Reduces disaster risk
• DISADVANTAGES– Collateral damage
• E.g. collapsing buildings, ground liquefaction
Compounds the disaster risk!
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.
