Economic growth is also threatening the quantity and quality of Egypt’s water resources, exacerbating the existing issue of shallow groundwater contamination from industrial chemicals and excessive fertilizer and pesticide

For the first time, an integrated assessment that includes climate change predictions, hydrological modelling and socio-economic vulnerability has been developed for the Arab region

Groundwater levels in different regions of the UAE have dropped by 60 metres on average. This poses a significant challenge.

The source of the Nile is in the Nyungwe Forest in Rwanda. From there, it travels northwards for 6,718km, making it the longest river in the world

Data on surface water quality is both scarce and old. These were mainly on the White and Blue Niles . Water characteristics are subject to the source and the types of soils it runs through . The only possible sources of pollution are from agricultural residues and sugar industry, even though the self-purifying capacity of the natural systems is high

The total long-term annual renewable water resources are estimated at 120BCM, of which about 78BCM go to surface run-off, and groundwater recharge is estimated at about 42BCM per annum, 11BCM by qanats (underground water supply systems) and springs, plus 31BCM by wells.

The total usable water potential of Turkey is 112 Billion m3 of which 98 Billion m3 is surface water and 14 Billion m3 is groundwater. In order to monitor groundwater extractions and prevent overuse, a regulation on groundwater measuring was enacted in 2011.
