1 Center for Environmental Geomatics Climate Studies Division Manila Observatory Dissemination Workshop for Mapping Philippine Vulnerability to Environmental Disasters Klima Climate Change Center 8 July 2005

2 OUTLINE OF PRESENTATION OBJECTIVES OF THE WORKSHOP THE VM-DENR PROJECT WHERE DOES THE MONEY GO? DISASTER LANGUAGE THEORETICAL FRAMEWORK HAZARDS STATEMENT OF THE MAPPING PROBLEM THE GIS APPROACH CATEGORIES OF FACTORS DIRECTIONS

3 OBJECTIVES OF THE WORKSHOP Objectives –To disseminate findings of the project –To obtain feedback on the usefulness of results –To find out how best to inform the public about project results –To explore follow-up activities arising from results and feedback on them Mechanics

4 THE VM-DENR PROJECT Mapping Philippine Vulnerability to Environmental Disasters Spatial information Spatial analyses Targetted and localized action Susceptibility to and capacity to cope with stresses Collective impacts of damaging events upon our surroundings

5 WHERE DOES THE MONEY GO?

6 DISASTER LANGUAGE Risk = Hazard x Exposure x Vulnerability capacity of community to prepare, absorb, recover from hazard Vulnerability elements affected by hazard Exposure physical impact of disturbance Hazard likelihood of harm, loss, disaster Risk

7 Risk = H x E x V THEORETICAL FRAMEWORK

8 HAZARDS Natural –Typhoon –Drought (El Nino) –Earthquake (Tremor, Landslide) –Volcano –Tsunami Anthropogenic –Deforestation –Mining –Climate change (historical, projected)

9 STATEMENT OF THE MAPPING PROBLEM The concept of vulnerability, coupled with its geographic or spatial perspective, gives us meaningful insights. In particular, vulnerability mapping (VM) assists in spatial analyses towards the formulation of more effective ways to respond in terms of: –Policy and decision-making –Strategizing adaptation.

10 THE GIS APPROACH The GIS approach, as illustrated, facilitates:

11 Base mapping with administrative units, Grouping of map themes by categories and sub-categories, Breakdown of legends into variables and their corresponding characteristics, Overlaying and/ or correlation of themes of different types and forms, Change detection or multitemporal studies for monitoring conditions. THE GIS APPROACH Contd

12 Comparative matrices complement mapping by way of: –Spatial databases, based on which logical and/ or numerical operations are performed, –Comparison across spatial units, these being regions and provinces, –Comparison across different themes by category of hazards and disasters, –Merging of qualitative with quantitative assessments.

13 CATEGORIES OF FACTORS The Manila Observatory and its research partners have been aware of complex factors at play in the occurence of disasters: –Climate/ weather-related, –Geophysical, –Ecological, –Anthropogenic (Human/ Developmental).

14 CATEGORIES OF FACTORS Contd These categories guided the application of GIS in VM The boundaries of these categories are not strict or absolute or the categories are not exclusive. Each category of factors has unique characteristics. These complicate overlays and intersections within and across categories.

15 DIRECTIONS The generation of composite (aggregated) vulnerability indices via GIS is promising at both national and local scales. There is a need to localize disaster vulnerability identification and mapping for the country.
