Conclusions
MENA population will double by 2050
MENA economies will approximate European level by 2050
Water demand would grow from 270 Bm³/y in 2000 to 460 Bm³/y in 2050
Water deficit would increase from 50 Bm³/y in 2000 to 150 Bm³/y in 2050
Over-use of groundwater is already above 45 Bm³/y
Extreme efficiency could limit deficit to 100 Bm³/y
 Efficiency and new sources will be required to cover water deficits
