The changing paradigm of coastal management: The Portuguese case

摘要

Until the 1980s, the primary goal of coastal works projects was to ensure safety at any cost. This was addressed in an essentially physical manner. Today, concerns are no longer limited to safety; lifestyle and quality of life have become essential components in the successful construction of coastal infrastructure. Other aspects of development have also become important, such as environmental impact, attractiveness and sustainability. New social realities must be addressed, as must the voices of actors and interest groups. The synthesis of recent concerns over coastal public works projects has become increasingly difficult due to new assumptions of value, social acceptance and the sustainability of these projects. In this context, it is now common knowledge that decision making on a coastal issue should be based on multiple criteria, including technical effectiveness, costs, benefits, implementation and monitoring. Here, coastal issues are reviewed using the dual perspective of meeting current needs and ensuring future sustainability. It is shown that multifunctional facilities built near the coast are one viable solution for managing coastal erosion. The results of a case study conducted in a sensitive area of the Portuguese coast are also presented. Based on an exhaustive review of the literature, it is also shown that improving nautical sports and generating renewable energy should not be neglected. Finally, contemporary adaptation measures and future accommodation options are recommended. (C) 2019 Elsevier B.V. All rights reserved.
