Outline • The water scarcity backdrop • Roots, worldwide extent , e.g. MENA region. • Implications • Food production, health, environment, poverty, relations • Mitigation and alternatives
Water Scarcity Indices 500 - 1000 m3/capita/year chronic water scarcity 1000 m3/capita/year is, on average, the minimum amount of water required to satisfy a person’s need for drinking, hygiene and food water stress (1000 – 1600) <500 m3/capita/year beyond the ‘water barrier’ of manageable capability Source: MalinFalkenmarks (Stockholm International Water Institute)

Jordan • Climate: Mostly arid desert; rainy season in west (November to April) • Terrain: Mostly desert plateau in east (80%) • Population: ~5.723 million (2007), Growth ~ 2.2%
Freshwater Availability ~75% receives < 100 mm/yr ~ 87% receives < 200 mm/yr Source: NMP

Water Issues … • Availability: • insufficient per capita quantity • discontinuous supply ( two days per week) • Accessibility / affordability • Water supply is still subsidized by the government • water prices still affordable by the poor • water prices for tanked water are 8-10 times more than piped water • Water Quality: • Groundwater of increasing salinity • Surface water is inadequate for drinking without extensive treatment
Impact of Climate Change a 20% decrease in rainfall
