Three Major Water Problems in the Middle East

1. Absolute Water Scarcity

Most MENA countries below 500 m³/capita/year (absolute scarcity threshold). Drivers:

• Arid climate (<100 mm rain/yr in many areas)
• High evaporation (>2,000 mm/yr)
• Population growth (2–3%/yr)
• Economic expansion (agriculture, industry, desalination)

2. Water Quality Degradation

Contamination of surface/groundwater by:

• Untreated sewage (80%+ discharged untreated in some countries)
• Industrial effluents (petrochemicals, heavy metals)
• Agricultural runoff (nitrates, pesticides, salinity)
• Seawater intrusion from over-pumping coastal aquifers

→ Cholera, typhoid, hepatitis, long-term toxicity.

3. Unsustainable Management

• Groundwater mining: Fossil aquifers (Nubian Sandstone, Disi) depleted at 10–100× recharge.
• Inefficient irrigation: Flood irrigation (60–80% losses); slow drip adoption.
• Subsidized pricing: Water nearly free → no conservation incentive.
• Transboundary conflicts: Tigris-Euphrates (Turkey/Syria/Iraq), Nile (Ethiopia/Sudan/Egypt), Jordan (Israel/Jordan/Palestine).

Emerging Responses

• Desalination (Gulf states: 50%+ supply; Saudi largest producer)
• Wastewater reuse (Israel: 90% treated; GCC expanding)
• Demand management: metering, tariffs, drip irrigation, drought-tolerant crops
• Regional cooperation: Red Sea-Dead Sea, Nile Basin Initiative
