The recent FAO/SWALIM (2012) study considered that in the northern provinces of Somaliland and Puntland, where there is no perennial surface water, "total annually rechargeable groundwater (although not necessarily available for abstraction) in the major aquifer systems is theoretically equal to some 4.3 x 109 m³. Although this amount of water, equivalent to a flow of 139 m³/s looks very promising, the large area of these two regions - more than than 289 000 km² - means that groundwater water is still scarce.
Has there ever been mapping of aquifers in Puntland?
