CASE STUDY

BUYUK MENDERES RIVER BASIN-TURKEY

BUYUK MENDERES RIVER BASIN

PROTECTED AREAS

CLIMATE

The climate in the basin varies from the Mediterranean climate in the coastal regions and downstream to the continental climate upstream. The annual average precipitation in the basin is 635 mm. It is 999 mm in the downstream parts and decrease to 350 mm in the upstream. The amount of precipitation is high in spring and winter times, but low in summer

Recognition of problems and changes of several sectors (including industry, urban water treatment facility, irrigation system etc.)- Necessity of integrated approach- Setting up framework for stakeholder participation- Active dialogue and exchange of information among all stakeholders- Awareness raising and stakeholder participation

Water Pollution- Environmental Study- Technical and feasibility study for maintain water level of the Bafa Lake- Construction of rubber dam at Bafa Lake

DEVELOPMENT OF BASINI. Demand for Agriculture, Problems of

Drought and Floods

National Development Policy

• The Economy agricultural dependant (1960s).

• Priorities – Land and water resource. – increasing income level and

living standards of rural population

– Migration

III.APPROACH FOR INTEGRATED WATER RESOURCES MANAGEMENT

• Every stakeholder tries to solve these problems within their responsibility:– The industry, especially the leather

factories, scattered in the Uşak Province has been moved to the organized industrial zone and the construction of a common waste water treatment facility for the industrial zone has been completed.

– In the Denizli Province, an urban waste water treatment facility has been put in operation and the textile industry established a common treatment facility.

– Existing irrigation systems have been replaced with modern irrigation systems to ensure efficiency and save water.

– Non-governmental organizations have also initiated some projects.

III.KEY FOR SUCCESS• 1-Pilot implementation of the European Union Water

Framework Directive• 2-Capacity Building Support to the Water Sector in

Turkey

– Long-tetrm sustainable use – decrease pollution,– to prevent further deterioration of aquatic

ecosystem and areas depending on those ecosystems;

– to enhance the aquatic environment, amongst other by decreasing discharges;

– to raise awareness and stakeholder participation

• Within the scope of this project, active dialogue and exchange of information have been taking place with all stakeholders such as the Büyük Menderes Environmental Protection Union, Municipalities, Irrigation Unions, Chambers of Industry and Trade, and NGOs.

• Through these works, it has been targeted to communicate all the activities carried out in the basin to all stakeholders, to coordinate the activities and to create public awareness in the basin.
