BACKGROUND
Whats is ESI
Environmental sensitivity index (ESI) maps are a compilation of information about coastal shoreline sensitivity, biological resources, and human resources. This information is used in planning to create cleanup strategies before an accident occurs so that authorities are prepared to take action in the event of such a spill. Advance planning reduces the harmful consequences of oil spills and cleanup.
Why ESI is Important ?
Coastal area is productive but sensitive, it requires a sensitive area identification :
Prioritizing the area development
Identification of transportation routes
Input for environmental management
Minimizing environmental damage
Integration ESI in Oil Spill Contingency Plan
The Goals
Identification of biological and socio economical environmental sensitive of a coastal area, presented in a spatial map form
Identification of habitat typology and ecosystem function
Analyses of a composite environmental sensitivity index
Identification of socio economy function of a habitat
Mapping of environmental sensitivity index
Benefits
As a basis data for environmental management of the area related to the oil and gas exploration activities (e.g. oil spill response plan).
As an input in protecting a sensitive area and important ecological and economical purposes of the area from oil and gas related activities
Minimizing environmental conflict
Minimizing social conflict
