“…for wheat and barley. Agriculture in Libya developed remarkably during the last two decades, as can be seen from the large increase in the irrigated areas, which has doubled during the period 1975-2005 [11,15]. The cultivated area has also increased, from 282,250 ha in 1975 to 470,000 ha in 2000 [15].…”

The cultivated area has also increased, from 282,250 ha in 1975 to 470,000 ha in 2000 [15]. Increased agricultural activities have resulted in higher demands for groundwater, irrigation water and applications of fertilizer and have also resulted in higher salinity (nitrate, chloride, Na, Ca, Mg, ammonia) and increases in some trace elements in soil [3].…”

The first step of aquifer parameter and dependent variable estimation based on hydraulic modeling is generally to choose the best steady-state condition for the set time period. In order to define the best estimated hydraulic conductivity and boundary condition for Gareh-Bygone Plain in arid southern Iran, ten different steady-state conditions were simulated and calibrated with limited field observations. The investigated area covers about 6000 ha with a floodwater spreading system that was established on about 2000 ha to artificially recharge the groundwater. The results showed a consistency over the 14-year simulation period with estimated hydraulic conductivity in a quite narrow range. This makes us believe that even if the modeling problem is to some extent over-parameterized the results appear quite robust. This is further strengthened by verification of the model results. Furthermore, the results showed that in the steady-state groundwater flow with no recharge from surface water, the system is mainly recharged by the fault which conducts water into the area from an upper sub-basin.

“…Libya's vast oil wealth has resulted in a rapid increase in both population and water consumption rates with regard to domestic, agriculture and industrial purposes (Abufayed, 2001).Water is a severely limited resource in some parts of the country due to the low rainfall average; typically the average yearly rainfall is less than 100 mm and the evaporation as high as 6.8 mm/per day (Shaki and Adeloye, 2007). As a result of severe environmental surroundings, over 80% of the Libyan population lives along the coast of the country where the majority of fertile land is.…”

In Libya, as water resources are rapidly being exhausted due to an increase in both population growth and water consumption in various sectors, the Libyan government has turned to integrating non-conventional water resources such as multi-effect distillation (MED and MED with TVC) in order to compensate for the water deficit. This paper has determined that the cost of desalinated water by thermal desalination plants is about $0.47/m 3, thus seeing this as the best option for providing water resources, due to unlimited seawater sources, compared with the cost of a cubic meter produced by the Great Man-Made River Project which is estimated to cost 0.83$/m 3 . Moreover, the results indicate that, the highest annual water deficit in Libyan water regions was in Jabal Nafusah and Jifarah plain, Middle Zone and Aljabal Alakhdar Region in the north and middle of the country equalling 1,450 million m 3 , 250 million m 3 and 60 million m 3 respectively.
