Vulnerability mapping as a tool Vulnerability assessment at sub-national levels Socio-economic dimension of vulnerability assessment Public discussions & Research …appropriate CC-policies
Vulnerability to CLIMATE CHANGE CLIMATE CHANGE VULNERABILITY MAPPING Climatic Hazards Vulnerability to CLIMATE CHANGE Sensitivity Adaptive Capacity IPCC FRAMEWORK
Climatic Hazards Tropical Cyclones Drought Flood Landslide Sea level rise
Tropical Cyclones Tropical cyclone frequency (event per year from 1980-2003) Source: UNEP-PREVIEW
Drought Drought frequency (event per year from 1980-2001) Source: UNEP-PREVIEW
Flood Flood frequency (event per year from 1980-2000) Source: UNEP-PREVIEW
Landslide Landslide Exposure Index Source: UNEP-PREVIEW
Sea Level Rise Sea level rise (5-m inundation zone) Source: CRESIS
Population displaced by 1m and 5m SLR Source: Authors’ calculation
All Climate Hazards Index All hazards Index Source: Authors’ calculation
Sensitivity Population Density Extent of Protected Area
Population Density Population Density (persons per km square) Source: CIESIN
Extent of Protected Areas National Protected Areas Source: WWF
Sensitivity Index of sensitivity Source: Authors’ calculation
Adaptive Capacity Socioeconomis Human Development Index (Income, Longevity, Education) Poverty Incidence Inequality Technology Electricity Coverage Extent of Irrigation Infrastructure Road Density Communication

Adaptive Capacity Index of Adaptive Capacity Source: Authors’ calculation
Human Development Index Source: various sources and author’s calculation
Poverty Incidence Poverty incidences (percent of poor population, national poverty line) Source: various sources and author’s calculation
Inequality Gini Coefficient Source: various sources and author’s calculation
Electricity Coverage Electricity Coverage (% of households with access) Source: various sources
Road Density Road Density (length of road/1000 km2 in logarithm) Source: various sources
Extent of Irrigation Percent of irrigated agriculture areas Source: various sources
Communication Percent of population with access to fixed phone network Source: various sources
Climate Change Vulnerability Index of Climate Change Vulnerability Source: Author’s calculation
Vulnerable Regions (SEA std) Vulnerable regions: Areas falling in the 4th quartile Source: Author’s calculation
SEA Mapping shows: Climate Hotspots: Big parts of Philippines; Cambodia & Lao PDR Mekong River Delta Bangkok West Sumatra, South Sumatra, Western Java, and Eastern Java of Indonesia Adaptive capacity is generally critical in reducing vulnerability Key cities in SEA are vulnerable!
Mapping as a decision making tool Visualization aid Vulnerable/hot spots; It enables us …to bring the socioeconomic dimensions in vulnerability assessment Allows downscaling of Vulnerability Assessment: sub-national levels (590 provinces/districts) Facilitates discussions of major stakeholders Media Citations National Debate/discussions Local government interests Blog discussions on the methods/areas for improvement Potential: Sub-national Decision Support system (Pilot testing)
Limitations/Future Works Static Analysis: changes & future events Data limitation prevents more extensive coverage of variables and use of better proxies Ad-hoc approach for the weights in calculating indices sensitivity analysis and incorporation of uncertainty Sectoral adaptation capacity/needs Development of a program for this decision-making tool
FYI: What other research do we do? Efficient use/Cost-effective adaptation options Ways to remove barriers to adoption Finding ways to enhance Adaptive Capacity (all levels, sector) More studies on the economics of adaptation options & adaptation behaviour.
