The aim of this guideline is to aid maritime administrators, or other lead agencies working with ballast water management, to assess and quantify (as appropriate and possible) the potential economic consequences of unintended marine species introductions. Such economic understanding is intended to support sound decision making in relation to IAS risk reduction, preparedness and response planning, and in particular as a source of information for the development of a National Ballast Water Management Strategy (see GloBallast Monograph No. 18).
The successful use of these guidelines does not require specialist knowledge of environmental economic approaches and methodologies. However, the involvement of environmental economic specialists to undertake a technical assessment is strongly recommended.
