Abstract(s)

Coastal lagoons occupy about 13% of the world’s continental coast. They are highly ecologically and economically valuable in the coastal zone and therefore are subject to anthropogenic pressures and require sustainable management practices. The relation between river basin and coastal zone make the ICARM the management practice fitting the best for coastal lagoons. According to the ICARM planning process science has an important role toward the implementation of integrated management. Using two study cases in two very distinctive lagoons: the Patos Lagoon (Brazil) and the Ria Formosa (Portugal); it has been pointed out that science is the required basis to achieve sustainable management of coastal lagoons. Moreover, the European Water Framework Directive being the main legal support toward an ICARM in Europe, the OSPAR comprehensive procedure has been applied in the Ria Formosa showing that it is a good tool that natural sciences can use to inform managers on eutrophication for the implementation of the WFD. Implementation of the WFD in Brazil would encounter important challenges and would not be possible nowadays. The scientific basis exists in the Patos lagoon to apply the comprehensive procedure in the future. Both study case pointed out that surveillance monitoring is a critical parameter in integrated management process.
