Acheloos River Diversion, Greece


Description

The plan of diversing Acheloos River was first initiated in 1925. Main goal of the project was to transfer water from Acheloos River in Western Greece to the plain of Thessaly in East Greece, through the Pindos mountain chain. Thessaly plain is the biggest agricultural area in Greece, and since early 80’s the implementation of the project has been used as a promise to Thessaly’s farmer by many political parties, especially the main ones. In the meantime the production of electricity was also added to the project goals. It’s still one of the biggest, environmentally destructive, technical complicated and expensive projects in Greece.

Project Details and Actors
Project DetailsThe current scenario comprises the diversion of 250 hm3/year and the flooding of two villages and a monastery amongst other with the construction of:

A dam and a reservoir in Messochora (constructed); a tunnel for water transfer from Messochora to Glystra (constructed) and a Hydroelectric Power Plant (HPP) in Glystra; a dam, a reservoir and a HPP in Sykia (under construction); a tunnel for Acheloos’ diversion to Thessaly from Sykia to Pefkofyto (constructed) and HPP in Pefkofyto ; a dam, a reservoir and a HPP in Mouzaki; a dam and a reservoir in Pyli; a tunnel connecting the reservoirs of Pyli and Mouzaki; a reregulating reservoir and a small HPP in Mavrommatis

Development of AlternativesEnvironmental NGOs along with university professors and researchers insist that water scarcity and pollution problems in Thessaly plain won’t be solved by Acheloos River diversion and the transfer of more water. The open irrigation channels, the crops (mainly cotton and other crops with high irrigation needs), the irrigation and agricultural technics (ie irrigation cannons, irrational use of pesticides) and the irrational water use (ie time of irrigation), are responsible for the degradation of surface and underground aquifers in Thessaly plain. There are concrete suggestions for the construction of small dams and the better exploitation of rainwater in the plain, the enrichment of underground aquifers, the change of crops and of the agricultural and irrigation technics. These measures will improve the agricultural production and the financial situation of the farmers in Thessaly, without destroying another area (the Region of Western Greece).

Unfortunately, the government and the ministries constantly ignored the alternatives proposed and they insist on the continuation of the works.
Do you consider this as a success?Not Sure
Why? Explain briefly.The case of Acheloos River diversion can be considered as an environmental justice success, as there are 7 decisions from the Council of State against the project. However, for twenty years, governments ignore these decisions and continue the construction. Today, Messochora’s dam is constructed; the tunnels for transferring water to Thessaly plain have been opened, although support is needed and there are problems of water inflow; Sykias dam is under construction. This infrastructure has already provoked major degradation of the environment. Furthermore, the Ministry of Environment, Energy and Climate Change, in an effort to make the project be in accordance with EU legislation, present it as an environmental rehabilitation, trying to overcome juridical objections. Given that, the movement declares that it will continue to fight for the definitive cancelation of the project.
