Hydrogeology of Djibouti

Djibouti, located on the Gulf of Aden at the mouth of the Suez Canal, was in antiquity part of kingdoms with strong links to ancient Ethiopia and Egypt. Its proximity to the Arabian Peninsula meant Islam was adopted early. It was colonised by France in the late 19th century, and the construction of railroads to Ethiopia meant it became an important regional port. It won independence as the Republic of Djibouti in 1977. The independent country’s first president remained in power until 1999. In the 1990s the country experienced a civil war that ended in a power sharing agreement in 2000, since when there have been periodic episodes of civil unrest and a number of contested elections, but overall, it is perceived internationally as having relative political stability.
This, combined with Djibouti’s strategic location, have led to it being the site of a number of military bases for foreign personnel, including US troops, as well as continuingly important ports, which bring in the majority of national revenue, and therefore foreign relations are very important to the country’s economic stability. The Djibouti franc is pegged to the USD. The economy is dominated by the service sector, which accounts for 80% of GDP, with commercial activities focused on the country’s free trade policies and transport links. Industry, including fishing and fish processing, and growing salt production, accounts for around 17% of GDP. The desert environment limits agricultural production, which accounts for only 3% of GDP. Rural people traditionally relied on nomadic pastoralism, but rural populations are low: three quarters of people live in cities. Djibouti’s limited natural resources mean it relies heavily on energy and food imports. Despite the importance of services to the economy, there is very high unemployment. Nevertheless, relative political stability also means that the country hosts many refugees, from surrounding African countries and more recently from Yemen.
Djibouti is an arid country with very limited surface water resources. Over 90% of water supplies come from groundwater. In some areas, groundwater levels are known to be deep and/or groundwater is known to have high levels of mineralisation
