Abstract:
The Environmental Vulnerability Index (EVI) Calculator is for people and organizations wishing to better understand the issue of environmental vulnerability and resilience as a basis for ensuring sustainable development through the application of the Environmental Vulnerability Index (EVI). To be able to calculate an EVI requires the compilation of relevant environmental vulnerability data for
... the 50 indicators. Once compiled then this data must be used to calculate each indicator. As the indicators are heterogeneous, include variables for which responses are numerical, qualitative and on different scales (linear, non-linear, or with different ranges) they are mapped onto a 1 - 7 vulnerability scale. Where data is not available, no value is given for the indicator and the denominator of the average adjusted down by one value. Where an indicator is considered 'non- pplicable' in a country (such as volcanic eruptions in Tuvalu which has no volcanoes), the lowest vulnerability score of 1 is attributed to that indicator. The vulnerability scores for each indicator are then accumulated either into categories or sub-indices and the average calculated. An overall average of all indicators is calculated to generate the country EVI. The EVI is accumulated into three sub-indices:
- Hazards
- Resistance
- Damage
The 50 EVI indicators are also divided up in the issue categories for use as required:
- Climate change
- Biodiversity
- Water
- Agriculture and fisheries
- Human health aspects
- Desertification
- Exposure to natural disasters
