  • Case Study 17: A Transboundary Water Scheme
    • Lesotho Highland Water Project (LHWP)
      • Agreed btwn South Africa and Lesotho in 1986
      • Six major dams built with 200km of tunnels to tranfer water from Senqu river basin in Lesotho to SA
        • Water then reaches Gauteng for large industrial cities (e.g. Jo'burg)
    • Problem
      • South Africa has limited water
        • SA has uneven rainfall
        • Non-even distribution of rain
        • SA has large people without water access
        • Jo'burg is a large city that does not get enough rain to supply its water needs
      • Lesotho has too much water
        • Lesotho is a small LEDC countries surrounded by South Africa
        • Lies 150km south of Jo'burg
        • Mountains of Lesotho have the source of the Orange River
        • Area gets 1200mm of rain / year
    • Advantages of Scheme
      • Lesotho is a poor country with few natural resources except water
      • Dams will provide HEP, providing cheap renewable electricity for Lesotho
      • Construction of dam created jobs
      • Reliable supply of safe water for Gauteng proviece
    • Disadvantages of Scheme
      • Lesotho has water shortages
      • Water bills in Jo'burg increased
      • 20k were forced from their land as it flooded due to the dams
