One of coastal hazard in risk of occurring in Greece is coastal floods because of the rising sea levels caused by climate change. The Mediterranean Sea in particular has been rising at a rate of 1.2-1.5 millimeters a year before 1960 then lowering to 1.3 millimeters a year after that. However the newest study from satellite altimetry showed the average could rise up to 5 millimeters per decade. (2) However even that being said, the risk is not as high as one would expect because Greece's tidal ranges are really quite small given the region of the world it is in. The reason this could be an issue however is that if coastal flooding were to occur, it would affect the 80% of Greece's industrial activities that occur on the coasts and 90% of touristic and recreational activities. (3)
Greece also experiences coastal erosion because of the constant wave actions occurring the smaller islands. Coastal erosion alone is not the only issue as it is damaging the large ecosystems that reside in marine parts of Greece, as well as causing the people living in coastal cities to become displaced as it become worse. (4) There is also known cliff erosion in Greece, mostly in the eastern part of the North Aegean sea coast, as well as near the city of Alexandroupolis. The cliff erosion in this area has been found to cause deposition of sediment into the ocean and coast. (5)
In terms of coastal and cliff erosion, Greece unfortunately does not have much in the form of coordinated laws or mitigation strategies put into place because it is caused by a natural processes, only encouraging those living in Greece to opt to move more inland instead. If anything, the Ministry of the Environment, Physical Planning and Public Works, the Ministry of Mercantile Marine and the Ministry of Economy and Finance fund coastal projects and are in charge of spatial planning for residential and commercial development. (6)
Greece luckily does have mitigation strategies for coastal flooding, relying heavily on the Water Framework Directive, and on its assessment and management of flood risks. They have implemented a number of measure such as land usage regulations, insurance, emergency measures, and damage assessment. They have also developed flood risk and hazard maps to help plan potential new developments accordingly, as well as emergency routes. There are altimeters in place that calculate ocean levels that serve as warnings for the emergency services. (7)

Miriam,
ReplyDeleteI enjoyed reading your post. It was detailed and informative. I didn’t know that Greece coastline experiences the same hazards as the shores in the Middle East. It is so fascinating that there is like 6000 islands there. I would love to travel to Greece one day.
It it really interesting learning about Greece and the coastal erosion that is happening there. Living on the coastline can be hazardous and can have a big impact on peoples property. The ocean is eating up more and more property and homes as the sea level slowly rises. The country of Canada is facing coastal erosion as well from rising sea levels which cause storm surges and flooding. This causes erosion on the coast and it seems to be happening at a faster rate.
