Vulnerability According to
Frank
3 Major Lineages in Hazards Research
(Eakin and Luers 2006)
• Risks/Hazards
– Looks at proximity and likelihood issues ex: Do I live
in a floodplain? What are the odds of a flood?
• Political Ecology
– How a communities ‘adaptive strategies’ make them
more or less vulnerable ex: subsistence farmers v.
coffee farmers
• Resilience
– Ecological/Systems Perspective- How and why does
a system change? What is it’s capacity to respond to
change (this one is a toughie…)

Vulnerability to Famine
• Malthus (1798)- too many people, not
enough food
– Food balance equations
• Sen (1982) - plenty of food, just can’t get
to it
– ‘entitlements
• Deveraux et al (2006?)- it’s the
governments fault
– Institutional failures

• Livelihood Zones
(LZ’s) reflect Pol.
Ecology-resilience
approach to
Vulnerability
mapping
• Useful concept
• Shock thresholds
developed for each
zone type (ideally…)
• Difficult to update
and compare across
countries
Integrated Spatial Analysis = ‘A stinking mess’
• Livelihood Zones do
not equal decision
units

Food for Thought
• Do different definitions of vulnerability
really matter to the on-the-ground
decision maker?
• If you can’t measure it, how/should you
incorporate it into the decision making
process?
