摘要：In the last decades Coastal Management (CM) processes have been evolving, presenting different management methods, and the new frontier is at the so-called Ecosystem Based Management (EBM). However, to put into practice EBM, which takes into account ecosystem functions, processes and services of coastal and marine environments, understanding them as a set of ecosystems composed of ecological (natural), economic and social elements, it is necessary an ecosystem-based information. The present work proposes, presenting practical results, a methodological path of six stages: 1. Identification of ecosystems as "Management Units"; 2. Mapping, modeling and simulating ecosystems and their connections; 3. Identification and classification of ecosystem services; 4. Definition of values and quality of services; 5. Identification of related management procedures; and 6. Integration with policies and other management and legal tools. The concrete applications range from academic studies of identification and characterization of coastal and marine environments, to port’s environmental management processes, and the development of ecological-economic zoning at regional level, for example. In the full appreciation of the set of examples and initiatives for all stages of the model, it can be concluded that its application is wide, varied and considerably simple. Likewise, the multiplicity of possible applications of the model in practical actions aimed to support of an EBM, suggests that its use can grow and pursue innovative initiatives. The authors' expectation is that such a tool may, in fact, delineate and stimulate research and applications based on ecosystems in the quest for the sustainability of the coast and the well-being of its social actors.
