Table 8: Water Balance in West Asia⁽¹⁾
Scenario II: Supply Augmentation

Assumptions:

Available water resources are developed as follows:
Groundwater at 100 Mm³ a year, i.e. 2 000 Mm³ for each sub-region by 2015.
Desalination plant capacity is increased gradually to reach 3 000 Mm³ in the Arabian Peninsula by 2015.
Wastewater plant capacity is increased to reach 3 000 Mm³ in the Arabian Peninsula and 2 000 Mm³ in the Mashriq by 2015.
UN projection of population (1997) is applied.
Domestic and industrial consumption are secured.
Rates of water consumption are as shown in box 1.
Improved agricultural productivity will achieve 17 per cent saving in agricultural water demand by 2015 (see box 1).
Shared water resource disputes are settled.
