Summary
The management of the North-Western Sahara Aquifer System (NWSAS) / Systeme Aquifere du Sahara Septentrional (SASS), a large aquifer shared by Algeria, Libya, and Tunisia.
Description

<p>The NWAS is one of the major North African transboundary groundwater basins shared by three North African countries (i.e.  i.e. Algeria, Libya, and Tunisia) which covers an area of more than one million square kilometres. The NWSAS can be categorised as a multi-layered system of aquifers which embodies a huge stock of non-renewable groundwater. </p>

Summary
Construction of the Iullemeden Aquifer System &#40;IAS&#41; which is located in Mali, Niger and Nigeria, with minor areas in Algeria and Benin and covers a region of approximately 525 000 km2. The Iullemeden Basin represents a reservoir of good-quality water which requires proper management.
Description

<p>The IAS faces multiple constraints; in particular difficulties of access to water resources related to the excessive depth (over 600 m) in some regions. Moreover, the lack of sub-regional strategic water resources management has led to changes in aquifer hydro-dynamics and water quality degradation. It constitutes the main perennial resource of potable water and a strategic resource for the sustainable development of the concerned countries. </p>
