What is the Environmental Vulnerability Index?

EVI-Logo-New

A vulnerability index for the natural environment, the basis of all human welfare, has been developed by the South Pacific Applied Geoscience Commission (SOPAC), the United Nations Environment Programme (UNEP) and their partners. The index was developed through consultation and collaboration with countries, institutions and experts across the globe. This index is designed to be…

Environmental Vulnerability: The issue

Healthy, productive and protective environments, social systems and economies are the basis of sustainable development and human welfare. The environment is the source of all our raw materials and absorbs the pollution from our activities. In turn, whilst going about our daily business (social and economic) we use the environment and convert its resources and…


How the EVI Works

pitcai90.1

The EVI is based on 50 indicators for estimating the vulnerability of the environment of a country to future shocks. These indicators are combined by simple averaging and reported simultaneously as a single index, a range of policy-relevant thematic sub-indices and as a profile showing the results for each indicator. Simple averages across indicators were…

Other Organisations Providing Rating like EVI?

Are you aware of any other organisation providing rating similar to the EVI? (I am aware of the EPI from Yale University even though it is not measuring ‘only’ the vulnerability). Thanks for your help.


When was the EVI last evaluated?

I would like to know the date/year of the last update of the EVI data? Based on your website, it appears that the last update was performed in 2005. If so, could you let me know when the next review is due? That is correct. The last full evaluation of the EVI was in 2005….


How the ‘Hot Periods’ Indicator (No.4) works

4-Hot-Periods

“I’ve read the indicator description of the (Hot Periods) that is a risk to Canada, but don’t quite understand, I mean most of the warming happens in winter and other nations that are really susceptible to extreme heat events like China and Russia aren’t mentioned in hot periods risk, would you please clarify? Thank you.”…


The EVI 2004

ocean-die-off

This report presents the results for the Environmental Vulnerability Index (EVI) for 2004 across 235 countries and territories. Without exception, the environment is the life-support system for all human systems and is an integral part of the development success of countries. The Environmental Vulnerability Index is among the first tools now being developed to focus…


The Development Process

The first conceptual Environmental Vulnerability Index (EVI) appropriate for Small Island Developing States (SIDS) was presented by the South Pacific Applied Geoscience Commission (SOPAC) on 4 February 1999. This work was further developed at an Environmental Vulnerability Index (EVI) Think Tank, 7 – 10 September 1999 in Pacific Harbour, Fiji. Expanding the EVI to other…


The EVI Indicators

templatemo_image_04

Defining Indicators Environmental vulnerability has been characterised by three components or sub-indices. These sub-indices focus on ecosystem integrity and how it is threatened by anthropogenic and natural hazards. To be able to capture the complexity of these aspects of environmental vulnerability requires the development of a variety of indicators that target different spatial and temporal…
