Gabon

Water resources Located in Central Africa, Gabon has a dense hydrographic system with permanent rivers. Average rainfall is 1,800 mm/year (AMCOW 2018), ranging from 1,400 to 3,800 mm/year across the country (FAO 2016). The country’s aqueduct water stress for all sectors measured in 2010 was zero and is projected to remain the same by 2040 (Luo et al. 2015). This score indicates that there is low competition among water users relative to available surface-water resources. In 2016, water withdrawals by the municipal sector accounted for 96.6 per cent of total withdrawals. The oil sector accounts for 80 per cent of exports, which could explain the very low proportions of water used by the agriculture and industrial sectors (World Bank 2019).
