Coastal systems are places where people live and where a spate of human activity affects the delivery of ecosystem services de- rived from marine habitats; marine fisheries systems are places that humans relate to and affect mainly through fisheries extraction. A coastal landscape is a section of coastline that has a range of coastal features; some erosional, some depositional. It is distinguishable from neighbouring coastal landscapes by prevailing characteristics that dominate the form of the coastline there. The input of energy and sediment into the coastal zone. The coast is the interface between land and sea. The coast is an open system. Energy inputs from waves drive the system. They interact with the geology, sediments, plants and human activities along the coastline. Coasts have many different features, such as caves and cliffs, beaches and mudflats. Tides, waves, and water currents (flow) shape the land to form these coastal features. Some coasts are also changed by the flow of glaciers, which are huge rivers of ice, and lava from volcanoes.
