A Tetrapod (which, Japanese engineers are quick to remind you, is a proper name, even if it has become a generic catchall) is a four-footed, porous, concrete breakwater barrier used to prevent erosion and water damage by dissipating waves. In the following sections we will examine the current status of Japans coastal zone relative to the three functional aspects of coastal zones important to humans mentioned above-disaster prevention, human utilization, and provision of ecological services.

Thirty-seven per cent of coastal land has been lost to erosion and flooding between 2005 and 2017 An endangered heritage The phenomenon is all the more worrying, as the impact of erosion along the Ghana coast is only likely to get worse with climate change and rising sea levels.

Coastal regions are intensely dynamic areas, and are of critical important to humans. Of the protective structures, banks and seawalls were built primarily in the first 10 years of this 30-year period. 25, 886902 (2012). Damage caused by flooding has diminished in recent years, but it is unclear whether this is a result of efforts to protect the coastline, or the lack of severe typhoons in recent years.
