  • THE IMPACT OF WATER STRESS AND STRATEGIES FOR COPING Serap Öztürk Civil Engineer,North Cyprus
  • A GENERAL BACKGROUND
    • Water Resources
    • Groundwater(aquifers)
    • 13 groundwater bodies with a total area of 765.5 sq.km
    • Surface Water (Small dams)
    • 33 small dams ,18 for irrigation,15 for grundwater recharge
    • total capacity 16.5 mi cu .m
    • Desalination Plants
    • 3 in operation
    • Treated Effluent Of Wastewater Treatment Plants
  • A GENERAL BACKGROUND
    • Cyprus ,a country 95% dependent on groundwater,for domestic water supply and irrigation,the resources
    • replenished by precipitation
    • Gradual decrease in precipitation
    • Year Amount of rainfal(mm)
    • 2004 396.1
    • 2005 348.4
    • 2006 346.3
    • 2007 379.3
    • 2008 104.3
  • Effects of Human Activities
    • Overpumping the aquifers
    • Extensive use of fertilisers and pesticides
    • Construction boom
    • Lekage problems in water distribution systems
    • Lack of sewage systems
    • Reflecting defects in water management and the infrastucture
  • PROBLEMS
    • Adverse effects of decrease in precipitation and human activities
    • 1. Güzelyurt (Morphou) Aquifer
        • Chemichal Pollution
        • Microbiological pollution
        • Drops in water levels
    • Kyrenia Range Aquifer
        • Drops in water levels
    • 3. Yeşilköy Aquifer
        • Turba formation
        • Microbiological pollution
        • Drops in water levels
  • PROBLEMS
    • Surface Waters
    • Continuous decrease in the amount of water collected
    • Year % of total capacity Amount of water(mi .cu.m)
    • 2003 88% 14.52
    • 2004 91.3% 15.37
    • 2005 64.0% 9.32
    • 2006 56.2% 9.28
    • 2007 41.1% 6.79
    • 2008 20.0% 3.38
  • WATER SUPPLY AND DEMAND
    • The amount of water used for irrigation: 60mil. m3/year
    • The amount of water pumped from 132 borholes for domestic use:
    • 26 mil.m3/ year, approx 22 mil.m3 / year reaches consumer
    • Domestic water demand (including tourism activities): 30 mil. M3/year
    • Deficit in domestic water supply: 8 mil.m3/year
    • Future domestic water demand forecast (2025): 44mil.m3/year
  • NEEDS
    • Need to have control over irrigation(limitations on areas to be irrigated ,change irrigation methods, change crop patterns)
    • Need for better Water management
    • Need to have the legal framework to backup contemporary water management.
    • Need to have new water tarrifs.
    • Lekage detection
  • ACTIONS TAKEN
    • A Crisis Management Committee established.
    • A strategy plan prepared.
    • Work on Legal framework ongoing ,technical help from EU
    • Investment projects on water infrastucture being prepared under EU –Aid program.
    • A seawater desalination plant tendered for Gazi Mağusa.
  • ALTERNATIVE RESOURCES
    • Tranport by tankers ,as an emergency precaution.
    • Desalination plants.
    • Use of treated WWTP effluent for irrigation.
    • Pipeline for Water transporation.
  • WHAT CAN BE DONE JOINTLY
    • Data sharing and cooperation.
    • Joint awareness raising programmes.
    • Joint pilot projects for water saving
    • Joint actions for promoting use of grey waters.
    • Joint actions for promoting rain harvesting.
    • Never forget
    • Drought has no boundaries
