  1. Water Pressure: Population Growth and the Middle Eastern and North African Water Crisis By Ariella Kirtley Holly Niebergall & Amy Schultz

  2. Water scarcity: an average total renewable fresh water resource of less than 1,000 cubic meters per person per year. Absolute scarcity: below 500 cubic meters per person per year.

  4. POPULATION[4] • In 1960 , MENA's population was approximately 100 million. • By 2007 this number quadrupled to 432 million. • Estimates expect the region's population to reach 700 million by 2050. WATER SCARCITY[1] Water scarcity is estimated by looking at the population to water equation. Renewable water is defined as water in streams, aquifers, lakes, etc. that can be renewed over time by the water cycle of evaporation, accumulation and percipitation. • According to the 2007 MENA Development Report, per capita renewable water resources in the region 1950 were 4,000 m3 per year. • Currently, per capita renewable water resources are 1,100 m3 per year. • Projections indicate that this number will reach 550 m3 per person per year in 2050, compared to a global average of 8,900 m3 per person per year today and about 6,000 m3 per person per year in 2050, when the world’s population is projected to reach more than 9 billion.

  5. MENA’s life expectancy is increasing, and although fertility has started declining, statistics show that one in every three people living in the region is between ages 10 and 24 [4], creating a “youth bulge”. The following factors also contribute to increased population and therefore increased pressure on the region’s already stressed water supply: • Urbanization; and • Migration. [2] [2]

  6. DESALINATION Desalination is the process of removing salt from seawater to make it potable, or fit for consumption. Thermal, or Distillation Process With the thermal process, seawater is heated and the steam is collected and condensed. • Multi-Stage Flash (MFS) • Multiple Effect (ME) • Vapor Compression (VC) Membrane Process With the membrane process, seawater is filtered through a membrane which traps the salt. • Electro Dialysis (ED) • Reverse Osmosis (RO)
