Environmental Vulnerability Index

EVI title

The Environmental Vulnerability Index (EVI) was developed by a team at the South Pacific Applied Geoscience Commission (SOPAC) in Fiji led by Ursula Kaly and Craig Pratt with my collaboration and based on my initial proposal. The main work was completed in 2004 and it was launched at the SIDS preparatory session of UN Commission on Sustainable Development in 2004 and the Mauritius International Meeting on further implementation of the Programme of Action for Small Island Developing States in 2005. While developed to demonstrate the particular vulnerability of Small Island Developing States (SIDS), the EVI was calculated for as many countries as data allowed for comparative purposes.

The EVI interactive website that made its results available in a flexible format disappeared in 2020, so I am posting the main documents on my personal website so that this pioneering work will not be lost.
