| Common misconception with the beginning of the last century that the fresh water resources is a natural resources is limited and not subject to depletion, and therefore have not been fortunate interest in the accounts of the development processes. However, the increasing population growth and the growing consumption of fresh water in the sectors of the economy after 1950 and the emergence of a serious water crisis in different parts of the world. Led to a significant change in the concepts associated with fresh water, that fresh water is a national wealth is limited and subject to depletion. Which requires the adoption and systematic scientific planning to exploit it. Therefore, the conviction was obtained when the full international organizations. Particularly the agencies of the United Nations specialized in the field of water (that water is the problem of twenty-first century, and not energy) has reinforced this view of the Dublin Conference in 1992 and the Conference of Rio de Janeiro in 1994 when he pointed out that all of human health, welfare, industrial development, food security and order are all exposed to environmental risk unless they are freshwater management planning, environmental science for the present, as established for the future. With regard to the study area represented in Libya, one of the countries that rely desert to the achievement of water security on the ground water, as there are no permanent surface streams flow. But ground water is not enough and are suffering from depletion of human, led to a decline in levels of some underground water basins and increasing salinity. Which requires a water supplier Find tortured another, realize for the Libyan community water security in the present and future. Especially that Libya overlooking the Mediterranean coast, with salt water for a distance of approximately 1900 kilometers, it is possible to desalinate the water to become unfit for human use and others. |
