South Africa’s National Development Plan aims to eliminate poverty and increase food security in rural areas by 2030. South Africa has more than 4 700 impoundments constructed primarily for domestic, agricultural and industrial water supply. The Department of Agriculture, Forestry and Fisheries have proposed that these water storage and distribution impoundments be developed for inland fisheries and aquaculture in order to improve rural livelihoods and increase food security in South Africa.
