Acting for cooperation in the water sector in the Mediterranean - NEXUS

Approval Date
January 2016


Project Duration
January 2016 - December 2019


Financial & Technical Partners
The project is funded by the Swedish International Development Cooperation Agency (SIDA) and is implemented by the Global Water Partnership for the Mediterranean- GWP-Med, the Economic Commission for Europe of the Nations United Nations (UNECE)


Country of operations
 The study area is the transboundary basin of the Aquifer System of the Northern Sahara (SASS) shared between Algeria, Libya and Tunisia.


Main Beneficiaries
Algeria, Libya and Tunisia and all the national institutions of the Water, Agriculture, Energy and Environment sectors as well as the "SASS Concertation Mechanism".


The project aims to develop and evaluate the intrinsic links of the NEXUS approach "Water, Food Security, Energy, Ecosystems". The project focuses on three components namely:

  • A NEXUS assessment "Water, Food Security, Energy, Ecosystems" to map and describe / characterize the interconnections in the use and management of water, land, energy and ecosystems ;
  • An institutional analysis and evaluation of options for strengthening cross-border cooperation between countries,
  • The development of a common vision of the management of the SASS reflecting the priorities and aspirations of the countries and stakeholders of the different sectors using the water resources and setting out the general direction of the cross-border cooperation.


These include:

  • Strengthening the capacity of national governments on international water law, in particular the UN / ECE Water Conventions and the draft articles on the law of transboundary aquifers;
  • Demonstrating the benefits of transboundary cooperation in the shared basins / aquifers of the region, and to improve the political process to facilitate the establishment of cooperation mechanisms that will advance the SASS cross-border management.
