The regulation of sand mining in South Africa. Sand mining in South Africa is controlled by a complex regulatory system that can be distilled into three main themes: mineral regulation; environmental regulation; and land use planning regulation. In this thesis, it is hypothesised that sand mining is subject to all three regulatory themes equally.
Jul 01, 2019· 1. Introduction. Mining is one of few industries that change entire landscapes, making it the source of a variety of impacts (see Bebbington et al., 2008; Mudd, 2010).These impacts are geographical in nature, as mines are unevenly distributed around the world and disproportionately affect the communities or ecosystems nearest to them (Sonter et al., 2014).
