Mapping, Assessment & Management of Transboundary Water Resources in the  IGAD Sub-Region Project: Overview & general recommandations

Iullemeden Aquifer System: Transboundary diagnostic analysis - Volume I

The Transboundary Diagnostic Analysis approach, advocated by the GEF for International Waters, was applied to the water resources of the Iullemeden Aquifer System. It is a first on the African continent.

Mapping, Assessment & Management of Transboundary Water Resources in the IGAD Sub-Region Project: GIS/Data Base component - Vol. IV

The report is built out of three key environmental thematic areas: drought and desertifica-tion; flooding and erosion risk; water quality and pollution. These three areas were covered at national and sub-regional levels, meaning that the volume contains analysis of each of the 7 IGAD Member States and a general sub-regional analysis for each thematic area.

Outils de gestion des systèmes aquifères transfrontaliers de l’espace OSS : approche méthodologique

Indicateurs écologiques du ROSELT/OSS, Désertification et Biodiversité des Ecosystèmes circum-sahariens

La nature est un « bien public mondial » dont la saine gestion est l’affaire de tous. Ses ressources sont cependant limitées, en particulier en zones sèches, où elles sont la principale source de vie, ou de survie, des populations : nourriture, bois de chauffe, eau douce…

The lullemeden Aquifer System, shared by Mali, Niger and Nigeria, designates in the framework of this study a group of sedimentary deposits containing two major aquifers: the lntercalary Continental (IC) at the bottom and the Terminal Continental (TC) at the top.

The Great Green Wall Initiative of the Sahara and the Sahel

Since the early 20^th century, natural ramparts have been erected around spaces which are vital to local communities in the circum-Sahoron region. Initially aimed as a protection against encroaching sand and erosion, green belts (trees planted around ogglomerotionsl and green barriers (intensive afforestation on large tracts of land) have gradually evolved into exploitable and productive structures, thus contributing to improving local incomes.

The North-Western Sahara Aquifer System (Algeria, Tunisia, Libya): joint management of a transborder water basin

This publication presents the main obtained results from the implementation ofthe different components of the project: hydrogeological data collection, analysis, and synthesis; elaboration of a common database and an informationsystem; development and exploitation of the NWSAS mathematical model andthe regional sub-models; establishment of a consultation mechanism for thebasin joint management; socio-economic study and environmental study.
