How vulnerable do these 68 economies look on the proposed MVI? I imagine they and others will be interested. After all, while ‘vulnerable to climate change’ (for the V20) is not the same as ‘vulnerable to anything’ (for the MVI), they are both using the same word. Given how prominently and frequently ‘climate change’ and ‘vulnerability’ are connected in this context, I suspect some stakeholders would be expecting the two approaches to have a similar set of vulnerable countries
It turns out that the V20 economies are (according to the MVI) only slightly more ‘vulnerable’ than the average of the 142 countries that have an MVI score. On the other hand, they are materially poorer.
Consider this table of median values:
Lack of structural resilience
GDP per capita, PPP
Member of V20
Not a member of V20
In fact, many countries in the V20 have below-average MVI scores; and there are also countries that aren’t in the V20 but have notably above-average MVI scores. Consider this chart:
The blue labelled countries are non-members of the V20 with an MVI of above 65. The red labelled countries are members of the V20 with an MVI below 50 (by construction, 50 is the average MVI score, so below 50 means below average). The GDP per capita, in purchasing power parity (PPP) terms in 2017 international dollars, is just for contextual information; it isn’t used for determining which countries are labelled or not.
So clearly the countries that have self-identified as ‘vulnerable’ to climate change are not the same as the set you would choose based on the new Multidimensional Vulnerability Index with its broader concept of vulnerability. I’m not going to say which is right and which wrong, or whether both are right in their own way; just pointing out the fact.
That’s really all for today.
Here’s the R code that does this analysis. You can’t just copy it and run it in a fresh R session however, contrary to my usual practice; you need to have run the code for the last post’s analysis first, or be running this in a clone of my whole blog source repository.
