As global focus intensifies on the "adaptation COP," questions arise about those "particularly vulnerable to the adverse effects of climate change." But who exactly are these groups?
A recent working paper reveals that existing vulnerability indices yield very different answers. Climate agreements often emphasize least developed countries (LDCs) and small island developing states (SIDS).
SIDS gain significant attention due to their clear exposure to rising sea levels and tropical cyclones, exemplified by recent events like Hurricane Melissa. However, the analysis indicates that on average, SIDS rank in the lower half of vulnerability indices.
Contrary to popular focus, LDCs generally rank as more vulnerable across most indices compared to SIDS, suggesting a need to reassess priorities.
While SIDS require unique forms of assistance, greater emphasis on LDCs is essential for equitable adaptation financing. Additionally, differentiated rules are needed for loss and damage support.
The paper evaluates five prominent indices assessing climate vulnerability:
Each index incorporates dozens of indicators and was compared at three levels: overall risk, vulnerability, and exposure.
"SIDS tend to attract a lot of attention because of their obvious vulnerability to rising sea levels and tropical cyclones. Hurricane Melissa is just the latest reminder of that."
"On average, SIDS rank in the bottom half of the indices on vulnerability, and LDCs appear to be the more vulnerable group."
"The allocation of adaptation finance is extremely unequal, ranging from less than $1 to over $2400 per person per year, with SIDS attracting by far the most per capita."
Author's summary: While SIDS receive more adaptation finance per capita due to their exposed geography, least developed countries face greater overall vulnerability and need increased attention in climate adaptation funding.
