How do technological changes in artisanal and small-scale gold mining
The transition from artisanal mining to small-scale mining produces an increase in productivity and financial gains for capital owners (see Bikubanya & Radley in this issue). More and more, the means of production are in the hands of small-scale mining companies or miners' cooperatives (see Dunia & Geenen in this issue).
