Understanding social impacts by using new variables and a causal model diagram in New England fisheries.

This paper reviews the applicability of the Social Impact Assessment (SIA) process within the framework of US national environmental policy used in New England fishery management. Its aim is to develop a new approach to SIA that goes beyond identifying impacts through guidelines, to include an understanding and portrayal of causality and emergent relationships. The emphasis is on creating a new list of variables identifying social impacts and social change processes. These variables are used in a causal chain model to diagrammatically portray impact dynamics over time and scale. This approach intends to fulfill a need for an accurate and timely methodology used in fishery management to identify potential social impacts of management actions, in order to achieve ecological and socioeconomic sustainability.
