1 UNESCO International Hydrological Programme (IHP) Activities related to Groundwater Resources Management in the Sahel Zone

2 International Hydrological Programme The only global intergovernmental scientific programme on water resources in the UN system Created in 1975 after the International Hydrological Decade 6 year phases, unifying theme Member States define needs and plans of phases Growing emphasis on management and social aspects Global network of IHP National Committees, UNESCO water centres and chairs, WWAP, UNESCO-IHE

3 IHP VII ( ) Water dependencies: Systems under Stress and Societal Responses Groundwater resources activities Transboundary Aquifers Management (ISARM) Global Hydrogeological Map (WHYMAP) Groundwater and Climate Change (GRAPHIC) Groundwater for Emergency Situations (GWES) GEF projects executed by UNESCO

4 ISARM - Internationally Shared Aquifer Resources Management Initiative

5 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) subregion. 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 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

6 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) 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

7 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 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, ).

8 TBAs in Africa

9 Global TBA Information System

11 Legal Framework for TBA Management UN General Assembly Resolution on the Law of Transboundary Aquifers (2008) UNESCO-IHP provided technical expertise to UN ILC Recommendations for Member States for the management of shared groundwater resources

12 GEF Transboundary Waters Assessment Programme (TWAP) GEF Full Size Project ( ) Global Assessments of TB Aquifers, Rivers, Lakes, LMEs, Open Ocean UNESCO-IHP: coordination of the groundwater component Global baseline assessment, indicator-based Partnership for the execution being established following the ISARM approach

13 Partnership Arrangements (draft) 1. Core Group 2. Regional Coordinators and Expert Networks 3. Key providers of expertise and data

15 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 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

16 The Iullemeden Aquifer System: strengthening transboundary groundwater management in the Niger River 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"

17 Lake Chad SAP Implementation Project Objective: Achieve adaptive ecosystem-based management of the Lake Chad Basin (LCB) by implementing a full range of policy/institutional and technical reforms and establishing financial mechanisms contributing to the sustainable use and the maintenance of freshwater, ecosystem and biodiversity resources, in accordance with the LCB Strategic Action Programme (SAP) Cameroon, Central African Republic, Chad, Niger, Nigeria UNDP, Lake Chad Basin Commission, UNESCO-IHP Other partners: BGR, Ramsar, IUCN, AWF

18 Conclusions Science and research as indispensable basis to better understand and manage (shared) groundwater resources ISARM: framework for the assessment and management of TBAs GEF TWAP: advancing TBA assessment Proposals for few GEF projects: Iullemeden Niger River Basin and Taoudeni/Tanzerouft Lake Chad Basin SAP Implementation Synergies and cooperation in the framework the IAEA regional project
