Shared surface and groundwater resources

Morocco shares groundwater aquifers with its neighbours. These are summarized in Table 1.

Morocco also shares with Algeria the Bounaim-Tafna basin, which is located in the north-east of Morocco and the north-west of Algeria and covers 2,650 km² (approximately 70% of which is in Morocco). It is formed by two aquifers (confined and unconfined), which represent a major asset in a region that has suffered economically and socially from the ongoing conflict between Morocco and Algeria over the Western Sahara. The basin’s water is used mainly for agriculture (80%), which delivers few economic returns. Water abstraction is uncontrolled and the resource is overexploited.[1] The unconfined aquifer is heavily polluted by nitrate, and in some places untreated groundwater is used for drinking, risking adverse health impacts, especially to children (Map 1).
