An operative decision support system for integrated coastal management: an application to the Reghaia lake, Algeria

摘要

In this paper, a decision support system (DSS) for an integrated coastal management (ICM) isuddeveloped, where decisions arise from a maximisation algorithm, the stakeholders’ involvement inudthe choice among alternative management strategies is favoured, complicated assessmentudprocedures for non-economical indicators or relative weights to combine economic, social andudenvironmental indicators are not used, the integration between economic activities andudenvironmental status is depicted by referring to initial and sustanability conditions, both human andudenvironmental dynamics are taken into account, a spatial structure is adopted, by finding audcompromise between economic information (available at macro-level) and ecological informationud(available at micro-level), several economic, social and environmental policies are considered,udpredictions are based on a knowledge base that can be easily collected and that is reasonablyudreliable, by calculating the confidence level of results. Its application to Reghaa and Heraouaudmunicipalities, Algeria, suggests that the suggested DSS for an ICM meets all design and roleudcharacteristics required by Westmacott (2001) Journal of Environmental Management 62: 55-74.
