  • 6. Reasons for the rising demand
    • Rising global population – From 2.5bn to 6.2bn between 1950 & 2000. Yet water supplies per person decreased by 1/3 1970-90.
    • Economic development – which means industrial & domestic demand has grown.
    • Rising living standards – people use more water for showers, washing machines ……..
  • 7. Reasons for the rising demand 2
    • Industrial development – The growth of manufacturing depends on water – steel & paper are major water users.
    • Tourism – Massive increase in LICs, but take huge share of water resources ( golf courses, swimming pools)
    • Agricultural demand – More people means more food. Area of irrigated land doubled in the twentieth century.
  • 8. Reasons for the rising demand 3
    • Climate change – This will affect rainfall, evaporation & water availability. The dry areas of LICs will be hit hardest.
    • Energy – Consumption has increased with population growth & industrial development. LICs have vast untapped HEP resources. But storing water in reservoirs increases the amount of evaporation.
