Burkina Faso is a landlocked, francophone Sahelian country. Gaining independence in 1960 and changing its name from the Republic of Upper Volta in 1984, the country embarked on an ambitious programme of socioeconomic improvement with an autonomist agenda. A public uprising in 2014 and military uprising in 2015 was followed by elections, a new president, the reversal of many previous Marxist policies, and the country becoming a strong ally of the USA and France in West Africa.
 
 
 
Burkina Faso has a low GDP and rapid population growth of 3%. Agriculture is the main occupation of most of the population, but now represents only about one third of GDP. Livestock rearing is important across the country, with arable crops particularly in the south and southwest Mineral exports now make up the main export, replacing the previously dominant cotton, including gold, copper, iron and other metals. 
 
 
 
Rainfall is highly variable both annually and spatially. Most water needs are met by surface reservoirs, and irrigation by dams has been encouraged by government since 1973. Most of Burkina Faso is underlain by low productivity aquifers, and groundwater use for irrigation is minimal. Although many challenges remain in water services, the state owned water utility (ONEA) has made great improvements over recent decades, with more than 75% of the rural population and more than 97% of the urban population classed as having access to safe drinking water.
 
 
 
A food price spike in 2008 has had long-term impacts on agricultural activities, and consequently water use, including leading government to reinstate fertiliser subsidies and control prices of some commodities. Another current source of pressure on water and other resources is the presence of refugees from Mali and some other regions in the north of the country.

The Volta river basin covers 63% of the country’s area, across the centre, south and west. Tributaries of the Volta system include the Nakambe, Mouhoun and Comoé rivers. The headquarters of the Volta basin authority are in Ouagadougou.
+
The centre, south and west of Burkina Faso are drained by tributaries of the Volta system, including the Nakambe, Mouhoun and Comoé rivers. The north and east are drained by rivers of the Niger basin. Many of the smaller rivers are ephemeral, drying during the dry season. There are a number of natural lakes. Many valleys are dammed to store wet season rainfall: in 2001 there were approximately 2000 reservoirs with a total storage volume estimated at 2.66 billion cubic metres (Obuobie and Barry, 2012)

Average recharge rates are estimated at 5 mm/year in the drier north and 50 mm/year in the south, but locally, recharge can be much higher, with estimates ranging up to 250 mm/year (Obuobie and Barry, 2012). Estimates indicate that over the whole countries, groundwater abstraction is only a small proportion of recharge - less than 1% in the Volta basin, and more than 5% in the far north. However, locally, groundwater abstraction may exceed recharge.

=== Groundwater use===
  
Groundwater in Burkina Faso is used mainly for drinking water supply, particularly for small supplies in rural areas and smaller towns. The second city of Bobo Diolasso, which lies on a moderately productive aquifer, relies relatively heavily on groundwater. The capital Ouagadougou, lying on the relatively low productivity basement aquifer, is largely dependent on surface water, but some 15% of its water supply comes from groundwater, which is particularly important in the dry season.

Groundwater in Burkina Faso is used mainly for domestic water supply, particularly in small towns and rural areas; the city of Bobo Diolasso also relies on groundwater. Groundwater supplies around 15 per cent of water supply to the capital Ouagadougou, but is particularly important in the dry season. Some groundwater is used for small-scale market garden irrigation, for example supporting dry season cultivation in the south. It is also used for for livestock watering. Industry is the smallest user of groundwater in the country (Obuobie and Barry, 2012).
