STRYMON PROJECT

The Greek part of Strymonas River basin is located at the north of the region of Central Macedonia and covers an area of 6,472 km2. Strymonas River and Lake Kerkini are the main surface water bodies in the basin, which in turn contribute to the Serres plain with ground water. Lake Kerkini was constructed during 1933-36 mainly for protection against floods caused by Strymonas River. Soon after it was used as a reservoir for irrigation water.

Agricultural activities, which constitute the main threat to surface waters and groundwater in the basin, take place in its lower part (elevation less than +100 m), which covers an area of 100,000 ha. This is area irrigated by a dense irrigation network. The Land Reclamation Service of Serres (DEB-S) is responsible for the water resources management in agricultural area through its administrative and technical supervision of the General Land Reclamation Agency (G.L.R.A.) and of the 10 Local Land Reclamation Agencies (L.L.R.A.). These agencies manage the land reclamation works and the distribution of irrigation water. 

The main problems of the area that the project STRYMON is aiming to solve are:

a) Water losses through the distribution system

b) The high concentration of surface waters in nutrients originating from the cultivated field

c) Degradation of the downstream agricultural soils due to their irrigation with drainage water

d) Undesirable alterations in the hydroperiod of Lake Kerkini,

e) The intrusion of the sea into Strymonas during irrigation period due to its low discharge.

 

The STRYMON project entitled "Ecosystem Based Water Resources Management to Minimize Environmental Impacts from Agriculture Using State of the Art Modelling Tools in Strymonas Basin" (contract number LIFE03ENV/GR/000217) is a 4-years project co-funded by the European Union, the Hellenic Ministry of Agriculture, EKBY, the Directorate of Land Reclamation of Serres, the Development Agency of Serres S.A. (ANESER S.A.) and the Local Association for the Protection of Lake Kerkini (SPALK).  

Beneficiary of the project:

Greek Biotope/Wetland Centre (EKBY)
 

Partners:

Prefecture of Serres- Directorate of Land Reclamation of Serres

Development Agency of Serres S.A. (ANESER S.A.)

Local Association for the Protection of Lake Kerkini (SPALK)

 

Objectives

The overall objective of the project is to promote the sustainable management of surface waters and groundwater in Strymonas River Basin assisting the implementation of Water Frame Directive.

Specific objectives are:

  • To use State of the Art Modelling Tools and Methods for the Assessment, including spatial and temporal variations, of the impacts of agricultural activities on the status of surface waters and ground water in Strymonas basin,

  • to use optimization methods for the elaboration of solutions - by taking into account the needs of the aquatic ecosystems in order to address factors that have caused the problems to be eliminated, and

  • to disseminate the methodological framework as well as the results, contributing to the promotion of the sustainable water resources management at national and international level.

Innovation

The Methodological approach to the objectives of this project and the Use State of the Art Modelling Tools, are the main innovations of STRYMON project:

Methods

  • Use of State of the Art Modelling Tools and Methods for the assessment, including spatial and temporal variations, of the status of surface water and groundwater in Strymonas basin.

  • Wetland functional assessment.

  • Survey of farm management practices in the basin.

  • Consultation with stakeholders.

  • Preparation of alternative scenarios compatible with the agro - environmental police of EC for the protection and management of the area's water resources.
     

Tools

  1. Implementation of State of the Art modelling systems in hydrology for the assessment, of the spatial and temporal distribution, of the impacts of agricultural activities on the surface waters and groundwater in Strymonas basin.

  2. Satellite image analysis for crop pattern identification.

  3. Multi-objective programming for the elaboration of optimum water resources management plans.

  4. Consultation with stakeholders and authorities in order to prepare a commonly accepted water resources management plan.

  5. Dissemination of the methods, tools and results.
     

Expected Results

  • Estimation of:
       i. the volume of water requirements for agriculture
       ii. the water losses in the irrigation water distribution systems
       iii. the pressures exerted on surface water bodies associated from the use of agro-chemicals.

  • Appraisal of the cost of agricultural production associated with the use of water and agro-chemicals.

  • Assessment of the potential effectiveness of agro-environmental measures, in reducing the use of water and agrochemicals.

  • Preparation of alternative proposals for the sustainable management of soil and water resources.
