Large increases in water demand with very little recharge have strained Libya's groundwater resources, resulting in serious declines in water levels and quality, especially along the Mediterranean coast where most of the agricultural, domestic and industrial activities are concentrated. To meet these increases, Libya turned to desalination as a supplementary water resource as early as 1964. Both thermal and membrane desalination technologies have been used. This study shows that the problem of water scarcity is likely to increase further in the future. This study has three aims: first, to estimate the historical relationship between population growth and the various uses of water; second, to forecast water consumption according to the various uses; third, to estimate the elasticities of water demand and examine the effect of price, income, population and temperature on water demand in Libya in the short and long-run. To achieve these aims, an econometric model of Libyan water demand is constructed and estimated for the period 1975-2005, using the Box-Jenkins approach to forecast water demand and the Engle- Granger two-step approach to estimate the short and long-run elasticities of water demand. As a result this study provides considerable information for policy makers concerning current and future Libyan water demand.
