摘要

Greece is included among the most vulnerable regions of Europe by climate change on account of higher temperature and reduced rainfall in areas already facing water scarcity. With respect to wetland systems, many ephemeral ones are expected to disappear and several permanent to shrink due to climate change. As regards two specific wetlands of Greece, the change in hydroperiod of Cheimaditida and Kerkini lakes due to climate change was studied. Lakes' water balance was simulated using historical climate data and the emission scenarios I1I' for the period 2020-2050 and I1I' and I2 for the period 2070-2100. Future climate scenarios, based on emission scenarios A1B and A2, were provided in the context of the study of Climate Change Impacts Study Committee. The surface area of Lake Cheimaditida will undergo a substantial decrease, initially by 20 % during the period 2020-2050 and later until 37 % during the period 2070-2100. In Lake Kerkini, the surface area will decrease, initially by 5 % during the period 2020-2050 and later until 14 % during the period 2070-2100. Climate change is anticipated to impact the hydroperiod of the two wetlands, and the sustainable water management is essential to prevent the wetland's biodiversity loss.
