Abstract |
The great wealth of coastal areas, whether in terms of access to the sea, maritime trade, tourism, fishing, or natural resources, increasingly attracts urban populations. However if this precious coastal capital is unsustainably managed, the potential of its benefits can be easily undermined. Coastal urbanisation affects land use and cover of the shore, biodiversity, soil, water and air quality and global climate. Responsible coastal cities try to reduce their ecological debts on land and the sea. Urban coastal organs and functions have to boost the resilience of places and assist in transition to a civilisation of sustainability. Sustainable cities and oceans, among the priority areas of the Rio+20 conference and the dialogue for the post-2015 sustainable development goals, need ecological and environmentally friendly cells and neurons to thrive in harmony with the planet and the seas. Together with their citizens and stakeholders, they can play a cardinal role for exploration and protection of our precious marine resources.This chapter focuses on coastal cities as vital and interdependent ecosystems able to manage crucial amounts of scarce resources and materials, ensure food security, offer sustainable goods and services and reduce greenhouse gas emissions and waste, especially preventing marine debris. Many coastal cities provide outstanding models of emission-neutral, waste-free eco-neighbourhoods and intelligently designed waterfronts to celebrate the sea which links them to the conscience of the world. Furthermore, they can send an impulse for maritime routes to become vectors of responsibility for sustainable development. |
