THE GREAT MAN-MADE RIVER PROJECT

WATER RESOURCES IN LIBYA

Only 5% of the entire area of Libya exceeds 100 mm (4 in) annually. Evaporation rates are also high ranging from 1700 mm (67 in) in the north to 6000 mm (236 in) in the south

GROUND WATER 95.6%

SURFACE WATER 2.3%

DESALINATION 1.4%

WATER TREATMENT 0.7%

In a recent study conducted under the supervision of the UN Centre for Environment & Development in the Arab Region & Europe CEDARE, the Nubian Basin (of which Kufra is part) was estimated at containing 373.3 x 10^12 m3.

If the neighboring countries extract water at a rate of 1380 MCMY it is calculated that the reserve would last 4860 years.

Over extraction in these basins has resulted in seawater intrusion in the coastal aquifers with TDS levels reaching 7000ppm in the Tripoli region

These basins contain

10,000 – 12,000 cubic Km.

of economically extractable water

THE GREAT MAN-MADE RIVER PROJECT

03 October 1983

The General People's Congress held an extraordinary session to draft the resolutions of the basic people's Congresses, which decided to fund and execute the Great Man-Made River Project.

28 August 1984

The leader of the Revolution lays the foundation stone in Sarir area for the commencement of the construction of the Great Man-Made River Project.

Agricultural Land Developed 130,000 hectare approx. ( 20,000 farms )

About 100,000 existing farms will be supplemented with irrigation water from the project which will have great impact on their productivity and encourage the settlement of farmers and their families, hence a positive impact on the value of their property

  • The agricultural development projects are being carried out in three regions in Libya:
  • Benghazi Plains Region – net irrigated area 30,000 hectares 14,000 hectares to be developed as large farm projects.
  • Jefara Plains Region (Tripoli) - net irrigated area 80,000 hectares 1,500 hectares to be developed as large farm projects.
  • Al-Ghardabiya Plains Region (Sirt) - net irrigated area 20,000 hectares 5,400 hectares to be developed as large farm projects.

Tazerbo

  • The agricultural development plan aims to:
  • Realize the highest possible rate of self-sufficiency in grain and fodder crops.
  • Increase the capital investment and job opportunities in the agricultural sector.
  • Produce raw materials for the food processing industry.
  • Encourage and support agricultural settlement.

American Companies have already invested in the development of Large Farm Projects:

- 1300 Hectares – Benghazi Plains Region

(this will be increased to 14,000 Hectares in the future)

- 800 Hectares – Tarhouna

- Valmont Valley supplying Irrigation equipment

- Case supplying agricultural equipment

  • Investors with experience in the field are invited to participate in:
      • Implementation
      • Operation
      • Maintenance
      • Management and product marketing
  • Of the large farm projects

THE GREAT MAN-MADE RIVER PROJECT

We can conclude that, adequate fresh water supplied by the gigantic GMRA project, have become an integral part of the infrastructure (including real estate) in all domestic, agricultural and industrial aspects, both in rural and urban areas, so as these areas grow, the need for infrastructure increase.

slide17

THE GREAT MAN-MADE RIVER PROJECT

Which results in:

Encouraging people in rural areas to stay in their land, due to Agricultural expansion.

slide18

THE GREAT MAN-MADE RIVER PROJECT

In urban areas, the real estate prices will escalate due to the improvement of the life standards.
