Namibia spends about 3% of its Gross Domestic Product on the operation expenditures of it water utilities. This is by far the highest percentage of all Sub-Saharan countries. [38] Per capita, Namibia spends about 80US$ annually on water supply and sanitation, other countries in the region spend between 1 and 10 US$. Providing access to utility ...
Namibia is the driest country in sub-Saharan Africa and depends largely on groundwater. With an average rainfall of about 350 mm (14 in) per annum, the highest rainfall occurs in the Caprivi in the northeast (about 600 mm (24 in) per annum) and decreases in a westerly and southwesterly direction to as little as 50 mm (2 in) and less per annum ...
Groundwater levels in the area have dropped about 0.3 m further due to the presence of two big dams built on the Swakop River. [5] Notwithstanding the river’s irregular flow, some agriculture is undertaken in the Swakop River valley. Thus, the region is well known for its fresh produce, especially tomatoes, asparagus and olives.
Tsumeb therefore also deserves to achieve the status of a geosite. Other locations in Namibia that are of geological significance include traces of Triassic dinosauromorpha at Otjihaenamparero in central Namibia; the Fish River Canyon in southern Namibia is the second largest canyon of the world and is famous for its scenic beauty.

Across the world there’s a rapid depletion in the underground reserves of water that billions of people rely on for drinking, irrigation and other uses, new research has found.

Namibia is an arid, water-stressed country. [5] As of 2024, the Erongo Region sources its potable water from (a) groundwater aquifers from the Omaruru Delta, (b) the Kuiseb Delta and (c) desalinated water from the Erongo Desalination Plant. The water sources are "interconnected by a network of pump stations, pipelines, and reservoirs".
In the aquifer, groundwater flows from points of higher pressure to points of lower pressure, and the direction of groundwater flow typically has both a horizontal and a vertical component. The slope of the water table is known as the “hydraulic gradient”, which depends on the rate at which water is added to and removed from the aquifer and ...
