Aquatic ecosystems are an integral part of human history, contributing to the survival and evolution of human communities. The human relationship with aquatic ecosystems evolved changing rapidly from era to era. A significant percentage of the world's population now lives in coastal ecosystems and depends heavily on the ecosystem services they provide. Exploring these relationships over time is a new innovative branch of science that can effectively contribute to finding solutions for today. At iSea we believe that the study of the interaction that Greek local communities have historically had with aquatic ecosystems can help to better understand the social factors related to conservation and management and contribute significantly to the development of more effective practices.
