Papers presented at the 2nd International Conference on Coastal Cities and their Sustainable Future are contained in this volume. Since its successful introduction in 2015 the conference has continued to attract important research covering the integrated management and sustainable development of coastal cities. An increased world population and the preference for living in coastal regions has resulted in their ever-growing expansion. Whilst this creates economic growth, it also increases the need for improved resources, infrastructure and services. Coastal cities should be considered as dynamic complex systems which need energy, water, food and other resources in order to work and produce diverse activities, with the aim of offering a socioeconomic climate and improved quality of life. Consequently the integrated management and sustainable development of coastal cities is essential with science, technology, architecture, socio-economics and planning all collaborating to support decision makers. Planners need to explore various options and models to forecast future services, plans and solutions. Included papers examine some of these possible models and potential solutions with emphasis in the areas of: Landscape and urban planning; Infrastructures and eco-architecture; City heritage and regeneration; Urban transport and communications; Commercial ports; Fishing and sports harbours; City-Waterfront interaction; Marine industries; Water resources management; Quality of life and city leisure; Tourism and the city; Water pollution; Air pollution; City waste management; Acoustical and thermal pollution; Coastal risk assessment; Coastal flooding; Coastal processes; Landslides; Socio-economic issues.
