  • Alternative strategies for future water supplies
    • Restoration
      • At a local scale this can involve restoring meanders, replanting vegetation and using sustainable methods to manage water courses for people and the environment
      • Case Study: Restoring the Aral sea
        • In 2007 Kazakhstan government secured a $126 million loan from the World Bank to help save the northern part of the Aral Sea
        • The government has already built a dam to split the sea into 2 parts and the new loan is used to build a dam to bring the water back
        • Fisherman have been able to resume fishing
        • Rain has returned
        • The southern part of the sea is still shrinking
        • The waters from the Amu Darya and Syr Darya are controlled by other countries
    • Water Conservation
      • Involves reducing the amount of water used rather than truing to increase water supplies
      • In the UK around 22% of water does not reach the end user due to leakage
      • Reducing domestic consumption
        • Installing water meters
        • Reducing the amount of water used in lavatory cisterns
        • Planting drought resistant plants/crops
        • Using grey water to flush the lavatory or water the garden
      • Reducing industry consumption
        • Installing more efficient systems to reduce water costs
        • Agricultural irrigation=use of micro-irrigation techniques using drip irrigation
      • Role of technology in solving future problems
        • Desalinisation - provides 70% of Saudi Arabia's water but it is the most expensive option
        • USA uses reverse osmosis membrane technology to filter salt from brackish water
        • In developing countries intermediate technology is more appropriate e.g. water collection
    • Key Players
      • Political - International Organisations
      • Economic - World bank, governments etc.
      • Social- Individuals, residents, farmers etc.
      • Environmental- Conservationists, WWF
