7. THE GOULANDRIS NATURAL HISTORY MUSEUM GREEK BIOTOPE/WETLAND CENTRE LIFE Environment Yearly increase of the irrigation areas in Strymonas Basin

8. THE GOULANDRIS NATURAL HISTORY MUSEUM GREEK BIOTOPE/WETLAND CENTRE LIFE Environment Main problems a)the loss of water due to the incomplete or damaged irrigation distribution network b) salinization of the downstream agricultural soils due to the reuse of drainage water with high concentration in nutrients and salts as irrigation water c) undesirable alterations in the hydroperiod of the ecosystems of Lake Kerkini, due to the continuous sedimentation

9. THE GOULANDRIS NATURAL HISTORY MUSEUM GREEK BIOTOPE/WETLAND CENTRE LIFE Environment Main problems d) the high concentration of surface waters in nutrients (NO3-N and PO4-P) due to the intensive agricultural practices, which in turn end up in Strymonikos Gulf leading to its eutrophication and e) the intrusion of the sea into Strymonas during irrigation period due to its low discharge
