           Vulnerability Mapping
The EVI scale is a relative scale of vulnerability ranging from 1 – least
vulnerable (most resilient) to 7 – most vulnerable (least resilient).
                  Data requirement
The EVI by its very essence attempts to summarise a wide variety of
environmental vulnerability data for a country. The data needed
encompasses a range of environmental factors from:
       • meteorological data,
       • sea surface temperature,
       • geological and geographical information,
       • biological species and habitat data,
       • reserves,
       • human activities such as fishing, mining, pollution, population,
         legislation etc.
       • The diverse and wide-ranging nature of these data means that
         sources are widely dispersed and often require some effort to
         identify, collect and compile information.
