Description
Knowledge-based management, governance and resources conservation of the Niger Basin and the Iullemeden-Taoudeni/Tanezrouft Aquifer System (ITTAS) improved to support IWRM for the benefit of communities and the resilience of ecosystems The proposed project builds on a number of previous projects financed in the framework of the Sustainable Development Action Plan (SDAP) of the Niger Basin in order to achieve the Shared Vision. In addition, the Observatory of the Sahara and Sahel (OSS) has secured support from the African Water Facility (AWF), the Fonds Français pour l’Environnement Mondial (FFEM) to extend their work on the IAS so as to include the interlinked Taoudeni-Tanezrouft Aquifer System (TTAS), and the surface waters of the Niger River Basin. Finally, UNDP will contribute through on-going support from Country Offices.

The initiatives that will particularly contribute to the proposed project include :
* Initiatives from the African Water Facility and FFEM on groundwater will make significant investments (more than $ 2.5 million) to further understand the nature of the Iullemeden Aquifer System (IAS) and the Taoudeni-Tanezrouft Aquifer System (TTAS) resources. These investments build on the foundation provided by the UNEP/GEF MSP, which equipped the three countries with the hardware, software and human capacity to map and model groundwater resources. Additional field studies, mapping and modelling across the larger IAS and TTAS are expected to generate improved descriptions and maps which elaborate the aquifer resources including : geological, hydrogeological, environmental and socio-economic setting ; morphology (roof, wall and thicknesses) ; piezometry ; transmissivity and storage coefficients ; exploitation analysis ; hydrodynamic scheme and its various components (boundary conditions, hydrodynamic and hydrochemical relations and transfer function), among others . This work will further describe and model the linkages between the TTAS and the IAS and describe and model the hydraulic interactions including the quantity and quality of water exchanged, between the IAS and TTAS with the surface waters of notably the Niger River Basin
* Under the Niger Basin SDAP investment plan, key investment from the World Bank Project “Water Resource Development and Sustainable Ecosystem Management (WRDSEM-total finance US$ 500 Millions, expected co-finance USD$ 50 millions)” will improve the regional coordination as well as the development and sustainability of water resource management in the Niger basin. The German Cooperation (BGR/BMZ) is engaged in the sensitization on the ground waters sustainable development issues through the Project : “Support to the NBA in the ground water management of the Niger basin” project (expected co-financing of US$ 2.5million). The French Development Agency, under the “Niger HYCOS 2 Project (expected co-financing of US$ 3million)”, is establishing relevant water resource information system at the scale of the basin, supplied with recent and quality data and easily accessible to all types of users, particularly thanks to Internet technologies. Finally, the Canadian cooperation is strengthening the information and communication system, the NBA technical expertise and the monitoring-evaluation through the “Capacity building Program of the Niger Basin Authority (expected co-financing of US$ 2 million)”. In addition to the initiatives of the SDAP, the project will also build on the national actions for environmental management, particularly those relating to the prevention and risk management but also to the current actions of monitoring of the hydrological network carried out by the national water resource institutions. The contribution of local communities of the nine countries of the basin is also expected in the management of restoration projects. In kind contribution from NBA is expected in term of office space, management of human resources, etc.
* The main basic projects of the UNDP, to which GEF will finance additional activities, are covering the components 2 and 4 with a total budget estimated to USD$ 2.8 million. The UNDP/Cap-Net Program of UNDP will support the national capacity building and that of NBA by contributing to build the capacity of national stakeholders in the use of IWRM tools and climate changes. UNDP country offices will support government and communities on the implementation of ecosystem restoration actions, setting up funding mobilization mechanisms, poverty reduction actions and promoting the participation of the stakeholders. Other on-going UNDP initiatives include the strengthening of national capacities on climate changes risks and vulnerability management (e.g. BCPR Niger, PAGEDD Mali).

Finally, the proposed GEF project will be linked to new IUCN initiative “Integrated Management of the Niger River Basin".
