Harmonised Techniques and Representative River Basin Data for Assessment and Use of Uncertainty Information in IWM -Mitigation of the groundwater depletion hazard under data uncertainty, as well as the socio-economic impacts of different demand scenarios in the the Geropotamou basin, Greece -
HarmoniRIB - 2. Desertification by excessive pumping in the Messara valley, Greece
The Messara Valley located in Geropotamou basin is threatened with desertification due to uncontrolled use. A dramatic drop of about 20 m in the mean groundwater level during the last 30 years has reduced the available water and has created tension amongst the users. The groundwater level dropdown started with the introduction of pumping of the groundwater store for drip-irrigation of the main crop, olive trees. The problem of excessive water abstractions is multifold:a) Illegal pumping, b) Excessive irrigation, c) Illegal irrigation water trading and d) The irrigation network reliability .(see 2.1.2 Description of the problem - p. 8)
