|Aquaculture - Initial Environmental Assessment Series No. 5 (NORAD, 1992)|
An initial assessment has the objective of helping desk officers and planners to assess a project in relation to environmental effects. The assessment shall provide a survey of environmental effects likely to ensue if a project is implemented. Usually an initial assessment will be based on easily accessible information, former research, the local population's views, etc.
The initial assessment only identifies potential direct and indirect environmental impacts; estimates are not assumed to be substantiated by special accounts or registrations. That comes under a full assessment. An initial assessment ought to be mastered by personnel without specialist knowledge of that particular project type, or of environmental consequences in general. In the course of an initial assessment, the project desk officer may nevertheless find it necessary to consult environmental expertise familiar with tropical areas.
The initial assessment should attempt to clarify both positive and negative environmental impacts. However, since the major positive effects are usually included in the main project account, the initial assessment will tend to lean towards potential negative impacts.
The EIA-system affords no easy solution to weighing positive and negative aspects against one another in a decision-making situation. This is because there are seldom clear objective criteria or threshold values for which environmental effects are acceptable or not.
This booklet provides a survey of required information as well as questions that need to be answered in an initial assessment of aquaculture projects.
To offer a brief overview of the subject, Part I describes what this type of project normally comprises, and what environmental impacts in particular can be expected. It stresses an account of the special problems often faced by aquaculture projects in developing countries and tropical areas.
Part II offers a more specific account of the kind of information that ought to be available as well as questions that should be answered in an initial assessment of an aquaculture project.
