Authors’ contributions This work was carried out in collaboration between both authors. Authors Aristeidis Mertzanis and Asimina Mertzani designed the study, performed the impacts to the natural environment and the coastal zone by climate change and man-made interventions. Author Asimina Mertzani managed the analyses of the study, assisted with the “in situ” observations, revised the results and the draft manuscript. Authors Aristeidis Mertzanis and Asimina Mertzani elaborated the literature searches, the data of maps, aerial photographs, satellite images and proceeded to comparative observations on the changes has been the coastal zone in the areas under study. Both authors read and approved the final manuscript. Article Information DOI: 10.9734/IJECC/2019/v9i1130144 Editor(s): (1) Dr. Arjun B. Chhetri, Faculty of Engineering, Dalhousie University, Canada.

Many urban, peri-urban areas and Natural Parks, in low elevation coastal zones in Greece are experiencing or are at risk of Sea-level rise, storm surges, water and soil pollution, saline water intrusion (salinity), coastal erosion and shoreline retreat, floods, and droughts. Sea-level rise could erode and inundate coastal ecosystems and Original Research Article
