The continent’s renewable water resources average 3,930 cubic kilometres, representing less than 9 per cent of the global total (UNEP 2010). According to UNEP (2008), Africa’s wetlands cover approximately 1 per cent of the continent’s total surface area. Anthonj et al. (2017) acknowledge that in parts of sub-Saharan Africa, natural wetlands constitute the only accessible water resources, providing water, agricultural potential and livelihoods in otherwise uninhabitable landscapes, which is why they are being used extensively.
