Water Scarcity

Water Scarcity Indices

1000 m3/capita/year is, on average, the minimum amount of water required to satisfy a person’s need for drinking, hygiene and food

chronic water scarcity

<500 m3/capita/year

beyond the ‘water barrier’ of manageable capability

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

Consequences… Dead Sea!

The Red-Dead Proposed Canal

Less Food produced Locally

Water Scarcity

Public Health deterioration

• Children mostly affected• The poor get poorer

environmental degradation

• Pollution of rivers• More treatment , increase cost• Loss of biodiversity

Sectoral competition

• Agriculture• Tourism• Industrial

Increasing salinity of

groundwater

• Further Treatment • Higher costs

Interregional / international

Conflict

• Domestically • Trans-boundary

Quality of life deterioration

Water Scarcity can be an opportunity
