| Abstract | Coastal zones are inhabited by about 37% of the global population, most of which depend on the ocean for their livelihood. Coastal zones have also been the centers of rapid economic development and are likely to remain so in the development of blue economies. Climate change threatens blue economies because of rising sea temperatures and sea levels, and increasing frequency of extreme events, salinization, ocean acidification and deoxygenation, affecting coastal habitats, ecosystems and resources that are the foundations of blue economies. Land- and sea-based human activities related to coastal development add to these climate-induced pressures. This chapter addresses these pressures, their trends and impact on coastal systems, resources and the associated blue economy sectors, as well as strategies for management and adaptation. Case studies from the Seychelles and Bangladesh describe the efforts and pending needs for combating or adapting to the impacts of climate change. They identify improved scientific assessments based on observations and models as a critical need for effective coastal management that can support the development of sustainable blue economies. |
