18 September 2013: Chad, Egypt, Libya and Sudan signed a Strategic Action Programme to establish a long-term framework for managing the Nubian Sandstone Aquifer System (NSAS), the world's largest known fossil water aquifer system.
The agreement establishes a Joint Authority for the NSAS, with the aim of strengthening regional coordination and optimizing equitable use among the four arid North African countries.
The Aquifer is the main water resource for humans, livestock, irrigation and industry in this region, and is under pressure from increasing populations, agricultural expansion and decreasing water availability from other sources. The agreement seeks to strengthen transboundary water cooperation among the four countries to ensure water removal does not threaten water quality, harm the surrounding desert ecosystem and its biodiversity, or accelerate land degradation. The agreement is based on an ecosystem-based management approach (EBMA) and integrated water resources management (IWRM), and includes transboundary actions and targets that individual countries are expected to translate into national actions.
The agreement resulted from a technical cooperation project among the International Atomic Energy Agency (IAEA), the UN Development Programme (UNDP), the Global Environment Facility (GEF) and the UN Educational, Scientific and Cultural Organization (UNESCO). The project, which began in 2006, created an aquifer model to assist the countries in optimizing the aquifer's use for human needs and ecosystem protection. The project also improved understanding of the transboundary ecosystem threats and improved data sharing. The Programme will build upon this project by continuing to strengthen the countries' capacity to monitor groundwater quantity and quality, and providing a framework for transboundary cooperation.
UNDP Administrator Helen Clark congratulated the African countries on the agreement, saying cooperative management of their shared sub-surface waters “will help to ensure maintenance of livelihoods and ecosystems dependent upon the aquifer." The agreement was signed at IAEA headquarters in Vienna, Austria. [UN Press Release] [UNDP Press Release] [GEF Press Release] [Strategic Action Programme Agreement]
