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

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

LIFE Environment
• Use of state-of-the-art modeling tools and satellite image analysis
• Wetland functional evaluation methods
• Consultation with stakeholders• Farm management survey at
catchment scale• Agro-environmental policy and
measures
• Assessment of the status and trends of water resources at catchment scale
• Water needs for agriculture and wetlands
• Impacts of agriculture on water resources and wetlands
• Stakeholders’ needs• Cost associated with water services• Potential of agro-environmental policy
and measures, in reducing the use of irrigation water and agrochemicals
Methodological approach
• Optimization through modeling• Deliberation with stakeholders
Optimum management plans with respect to water, agriculture and wetlands
