|On 18 September 2013, the Ministers in charge of water resources in the four States of the Nubian Sandstone Aquifer System (NSAS) (Chad, Egypt, Libya & Sudan), and the Chair of the Joint Authority for the Study and Development of the Nubian Aquifer, signed an important document, the Regional Strategic Action Plan (SAP). The NSAS is one of the largest aquifer systems in the world, composed of non-renewable groundwater. It extends over 2,000,000 km2 and contains about 540,000 km3 of water, out of which 15,340 km3 is believed to be exploitable. Cooperation over the NSAS dates back at least to 1989 when Egypt and Libya established among themselves a Joint Authority (JA) for the Study and Development of the Nubian Sandstone Aquifer System. |
In 1992, the two States adopted the agreement - Constitution of the Joint Authority for the Study and Development of the Nubian Sandstone Aquifer Waters.
