Industrial development combined with the severity of sea conditions during typhoons and the fact that Japan has an inadequate natural supply of soil and sand, has resulted in a serious coastal zone erosion problem in Japan. For example: in the US, beach nourishmentwhere sand from outside locations is used to fill in eroding beacheshas long been a popular plan of attack for coastal defense schemes. Thus, Japan experiences relatively high sea temperatures and a warm climate given its high northern latitude. Such significant coastal erosion coupled with land subsidence was observed in Niigata Coast, Central Japan, where the . Blossier, B., Bryan, K. R., Daly, C. J. Paek, H., Yu, J. Y. Earth Surf.

Mod. A 24-hectare dry beach has been created along a breakwater to replace the dry beach at the mouth of a river which was been lost to harbor development. After the earthquake and tsunami hit [in 2011], weve been rebuilding everything, but a lot hasnt come back yet, Yoshinori Okuyama, Director General of the Sendai Bay South Coast Office, noted.

The coastal zone is classified into, for instance, harbors, fishing ports, and reclaimed agricultural lands. Instead, were building a good number of [underwater] artificial reefs that break the waves in order to preserve the view while still preventing things like erosion, Kato explains.

Some 37% of Ghana's coastal land was lost to erosion and flooding between 2005 and 2017. https://doi.org/10.1038/s41561-022-01117-8. The maintenance of coastal sand drifts provides another example of ICZM. As an island nation with roughly 30,000 kilometers of coastline, Japan's connection to the sea is as deep as the ocean itself. Change 5, 132137 (2015). Lett. Shelf Res. On the topic of whether or not some people believe that the addition of concrete is ruining the visual beauty of the beachfront in Japan, Kato quickly notes that those people living in impacted coastal regions (about 130 million of them) are far more concerned about their safety than any picturesque viewespecially in the wake of 2011s devastation and continued threats. 38 MANAGING COASTAL EROSION Gulf Coast The Gulf Coast is the lowest lying area in the United States and consequently is the most susceptible to flooding.
