The long-term principle concept is based on setting and achieving a vision for the future of coastal zone management. The vision for the sustainable development of coastal zone management includes utilizing new advances in scientific, technical, social and economic understanding of coastal sustainability. The coastal environment, dunes and beaches are outstanding natural assets. Their wildlife, cultural, historical and archaeological resources should be passed on to future generations in similar or better conditions than they are currently. The principle of long-term management can be analyzed according to these definitions (economics, ecology, ethics) concepts: comprehensive overview of systems, detailed investigation of issues, and the planning development of management practices that have a positive effect on the future.
