Compound Vulnerability: Redefining Climate-at-Risk Populations
In One Sentence
Korea's first national Climate Citizens' Assembly (2026, 200 deliberating citizens — 20 planning + 180 deliberating-only — established under Article 19-2 of the Carbon Neutrality Framework Act) is deliberating whether to redefine "climate-vulnerable populations" — moving away from single-variable proxies (low-income, elderly) toward a four-axis "Compound Vulnerability" framework combining housing, health, mobility, and social isolation.
Why This Matters — A Distinctly Korean Story
The 2022 Seoul Banjiha Floods: When Single Variables Miss the Victim
In August 2022, torrential rainfall hit southern Seoul. In a semi-basement (banjiha) dwelling, a family that included a person with a disability was unable to escape rising waters and died. Under Korea's existing "low-income household" criterion, that family was not classified as a protected vulnerable group.
What made them vulnerable was not income alone, but four overlapping conditions:
- Housing: Living in a banjiha — a uniquely Korean housing form, partially underground, structurally prone to flash flooding
- Health: A family member with a disability, limiting self-evacuation
- Mobility: Wheelchair access barriers in a narrow stairwell
- Isolation: Night-time event, no immediate help reachable
This single tragedy crystallized a policy gap: Korea's existing vulnerability definitions, inherited from welfare-era frameworks, are blind to climate-specific risk.
The 2024 Extreme Heat Season: The Same Pattern for Outdoor Workers
From April to September 2024 — Korea's longest recorded heatwave — multiple deaths were reported among outdoor workers in construction, logistics, and agriculture. Their vulnerability was similarly compound:
- Health: Pre-existing chronic conditions amplified by prolonged heat
- Employment: Day-labor and platform-gig contracts with weak "right to refuse work in dangerous heat"
- Housing: Older multi-family units, often far from worksites
- Information/Language: Migrant workers with limited access to Korean-language heat warnings
Again, no single variable — income, age, or occupation — captured the actual risk.
The Proposal — Professor Park Chan's Framing (Session 1, 28 May 2026)
In the Assembly's first lecture, Professor Park Chan (University of Seoul) argued:
"Defining vulnerability through a single variable like age or income is a 20th-century welfare framework. Climate vulnerability is compound — it emerges where Housing, Health, Mobility, and Isolation overlap. Korea must redefine its protected population in those four-axis terms."
This proposal upgrades the broader "social inequality" discussion (see [[05-climate-injustice]]) into an actionable policy definition.
What the Assembly Is Currently Deliberating
- Legal codification of the four-axis criterion — Recommending amendments to the Enforcement Decree of the Climate Crisis Adaptation Act and/or the Framework Act on Disaster and Safety Management
- Disaster-type weighting — How heat, flood, cold wave, and wildfire should each weight the four axes differently
- Mandatory publication of regional "Climate Risk Vulnerability Maps" — Building on the Ministry of Environment's VESTAP tool but adding four-axis household data, published at the city/county/district level
- Triple-line ministerial accountability — Integrating the Ministry of the Interior and Safety (shelters, early warning), Ministry of Health and Welfare (medical, care), and Ministry of Employment and Labor (work stoppages, breaks) into a single governance framework
How This Sits in International Context
| Reference | Korea's Adaptation |
|---|---|
| IPCC AR6 (2022) — "Risk = Hazard × Exposure × Vulnerability" | Korea is attempting to operationalize "Vulnerability" with a four-axis household-level definition |
| EU Just Transition (2020–) — Region- and industry-based vulnerability | Korea would push the unit of analysis down to the individual household |
| Canadian Adaptation Strategy (2023) — Compound vulnerability acknowledged for Indigenous and Northern communities | Korea would extend the concept beyond geographic/ethnic categories to a universal household-level definition |
If adopted as a recommendation by Korea's Climate Citizens' Assembly, this would likely be the first OECD member state to codify a four-axis, household-level compound vulnerability framework in climate adaptation legislation.
Open Questions Before the Assembly
- Is "four axes" the right granularity? Some members propose adding Information Access as a fifth axis (especially relevant for migrant workers and digitally excluded elders).
- How should the framework handle dynamic vulnerability — for example, a person who becomes vulnerable only during the heat season but not year-round?
- Who bears the administrative cost of household-level vulnerability mapping? Local governments lack uniform capacity.
- Should the four-axis label be publicly visible to the household (empowering them to claim protection) or administratively internal (avoiding stigmatization)?
