Research Paper output of the MarineSABRES project, the paper abstract includes: The coastal environment is a complex system formed by interactions between ecological structure and functioning, physico-chemical processes and socio-economic systems. An increase in competing uses and users requires a holistic approach to coastal management which considers the environmental, economic and societal impacts of all activities. If managed sustainably, the marine environment will deliver a range of ecosystem services which lead to benefits for society. The problem-structuring DAPSI(W)R(M) (pronounced dap-see-worm) framework is used to assess the causes, consequences and responses to change in a holistic way. Drivers of basic human needs require Activities which lead to Pressures, the mechanisms of State change on the natural system which then leads to Impacts (on human Welfare). Those then require Responses (as management Measures). The framework is used here to address the so-called ‘triple whammy’ affecting coasts worldwide – of increased urbanisation and industrialisation, increased use of physical and biological resources (such as energy, space, fishes, etc) and a decreased resistance and resilience to climate change (including sea-level rise, increased storminess, etc). In giving lessons for coastal management worldwide, this risk assessment and management framework is applied to the Balneário Camboriú – SC (Brazil) coastline which shows most of the features of coastlines worldwide and which is a major development area for Brazil. It particularly shows what may be called the `environment-tourism paradox’ whereby excessive coastal tourism eventually damages the desirable features initially responsible for the tourism and creates tensions between tourists and local inhabitants as seen in tourism hotspots worldwide.
