Water resources planning under climate and economic changes in Skiathos island, Aegean

Small Aegean islands are facing complicated pressures of different natures. Their physically limited water resources are invoked to cover the increasing needs of the local population, combined with the seasonal water demand peaks due to tourists. This often leads to aquifers’ overexploitation and se...

Their physically limited water resources are invoked to cover the increasing needs of the local population, combined with the seasonal water demand peaks due to tourists. This often leads to aquifers’ overexploitation and seawater intrusion, deteriorating the water quality. Water scarcity may also occur due to inadequate infrastructure, limited investments and human resources for proper management.
