Water supply
• Fresh water is essential for supporting all life on our Methods of improving water supply:
planet • dams & reservoirs
• to maintain the balance within eco systems • Wells
• domestic: survival, development, drinking, cleaning, • Boreholes into the aquifer
sewage deposal • water trucks
• energy production: generation of cheap, clean energy • water treatment plants
• agriculture, farming • rainwater harvesitng
• water transfer
• desalinisation
Water scarcity: the lack of sufficient available water resources to meet the demands of water usage within a region
Physical water scarcity: there is not enough water to meet both human demands and those of ecosystems to function effectively
Economic water scarcity: a lack of investment in water (infrastructure) or lack of human capacity to satisfy the demand for waters even in places where water is abundant / poor
water management
Water stress: there is often restrictions on usage as well as conflict for water supplies and dealing standards of harvests and security
Reasons for water shortages: Impacts of water shortages:
• Improper infrastructure: pipes not set up / • Water borne diseases: cholera, typhoid
lack of investment • Many women have to walk for hours and
• No natural water source - rivers, lakes or quit school to fetch water
low precipitation • Poor hygiene and sanitation
• Extreme climates: droughts, arid, desert • Can cause conflict
• Aquifer depletion (water obtained by soil • Impure water contains toxins such as
before humans can get it) dissolved metals
• No storage • Hunger: not enough water to grow crops
• No transport systems • People are tired, less concentrated…
• Decreases life expectancy
