ISARM in Africa Four sub-regional ISARM components have been established in

Sub-Saharan Africa - in West, Central and Southern Africa, and the Intergovernmental Authority on Development (IGAD) sub-region.

Milestones

2002 Tripoli Workshop produced the first inventory of African Transboundary Aquifers. For the majority of identified aquifers, only approximate location is known and no details on aquifer’s characteristics are available.

2005 IGRAC refined delineation of 20 transboundary aquifers in the SADC region and developed a web-based system for storage and display of relevant information. A course material on groundwater resources and transboundary aquifers in Southern Africa was developed

ISARM in Africa

2007 UNESCO-IHP, in close cooperation with national committees, the University of Western Cape and IGRAC, took initiative for establishing ISARM-SADC (launching meeting in Pretoria).

2008 Tripoli Conference Members of the ISARM core-group (UNESCO-IHP, IAH and IGRAC) supported the establishment of a Regional Centre for the Management of Shared Groundwater Resources in Libya

ISARM in Africa

2010 ISARM – IGAD Workshops held in Addis Ababa produced an update of the Transboundary Aquifer Map for the Horn of Africa. The second workshop was held in 2011 also in Addis Ababa.

2011 First ISARM Central Africa and Second ISARM West Africa Workshop in Douala, Cameroon. Both workshops were held simultaneously and organised within the framework of the regional ISARM initiatives implementation during the 7th phase of IHP (IHP-VII, 2008-2013).

Managing Hydrogeological Risk in the

Iullemeden Aquifer System (GEF MSP)

UNEP, OSS, UNESCO-IHP

Transboundary Diagnostic Analysis: Major Transboundary risks identified;

Common data base elaborated: more than 17000 boreholes recorded;

Geographic Information System developed;

Groundwater model developed : water budget, close relation between Niger river and aquifers (aquifers supply Niger river),

Legal and institutional framework adopted by countries

Basin and enhancing knowledge, management and

governance in the associated Taoudeni/Tanzerouft Aquifer

Systems

UNEP, OSS, UNESCO-IHP

Knowledge base, management and governance of Iullemeden-Taoudeni-Tanezrouft Aquifer System (ITTAS) improved, with linkages established between the ITTAS and management processes for the Niger river basin, contributing to the implementation of the UNGA resolution 63/124 "Law of Transboundary Aquifers"
