With a history of agriculture, fishing and trading dating back thousands of years, Chad became independent from French colonisation in 1960. Civil war and military unrest occurred sporadically from then until the current president took office in 1990. For at least two decades, Chad has been significantly affected by the arrival of refugees from neighbouring countries, including Darfur in Sudan and the Central African Republic, and by people internally displaced by unrest within Chad. Chad is also involved in international anti-terrorism efforts to tackle Boko Haram and Al Qaida in the Islamic Maghreb.

Rainfall is highly variable both spatially and temporally across the country. Lake Chad is the major surface water resource, shared with neighbouring nations. Droughts in the 1970s and 80, combined with anthropogenic activity, reduced the area of Lake Chad to record low levels, placed huge stress on water resources, and increased dependence on groundwater. Most rural areas of Chad depend on groundwater for potable water supplies and often for livestock, and in the north, for small-scale irrigation, and groundwater is also an important resource in many cities.
