In Libya there is a growing awareness of increasing demand for fresh water while fossil groundwater supply is limited. This situation of water supply has become more problematic with rapidly increasing population and low rainfall. Hence soon after the discovery of fresh groundwater in the deserts of southern Libya, the local authority has made huge efforts to address its water deficit problems, mainly through the implementation of "The Great Manmade River Project" to sustain its economy. Especially the agriculture sector exceeds its traditional supplies. The Libyan authority began to design and install the hydraulic infrastructure needed to withdraw and transport this fossil water to various demand sites along its Mediterranean coast where most of the population lives and where the water is used. There is an over-exploitation of fossil groundwater resources to meet the irrigation demands as a result of adapting a self-sufficing policy in food. Rapid development of agricultural activity, expansion of irrigated areas and over irrigation practices will lead to more depletion of water resources since most of the country’s groundwater resources are non-renewable. The supply-driven approach for water management has demonstrated its inability to deliver a substantial degree of water sustainability on the national Libyan level. Despite the strenuous efforts made by the country, it still faces serious water deficits due to continuously increasing water demands beyond the limits of its available water resources. As pressure on water converges on the country’s fossil water resources, an immediate reconsideration of agricultural water extractions is needed and appropriate actions have to be implemented in response to its huge consumption. This policy aims at rescuing the present water situation and at avoiding serious environmental and economical crises. Reorganisation of the water consumption pattern, to maintain the country’s standard of living and to ensure the economical security for the future generation is drastically needed. This paper considers the country’s water management that requires water policy reforms, with emphasis on supply and demand management measures and improvement of the legal and institutional provisions. This could be achieved by reviewing agricultural water policies in order to minimise some local deficits in water resources and to avoid water quality deterioration in the coastal areas. Developing additional non-conventional sources of water supply needs to be considered. This should be supported by creating authorised water institutions lead by a high-professional staff and enabling them in making the appropriate legislation and decisive measurements to allocate water among consumptive sectors as well as to ensure the protection of the environment.
