Water resources Chad has an annual rainfall of 322 mm (AMCOW 2018). The country has three climatic zones, with varying degrees of rainfall. Rainfall is 300 mm/ year in the north of the country near the desert, 300–600 mm/year in the Sahelian zone and 600– 1,200 mm/year in the Sudanian zone (FAO 2016). Water availability is about 92.8 m 3 /year per person (AMCOW 2018). The country’s aqueduct water stress for all sectors measured in 2010 was 0.37 and is projected to increase to 0.67 by 2040 (Luo et al. 2015). A score of 0.67 indicates that there is low competition among water users relative to available surface-water resources.
