Abstract
Since the beginning of the 21st century, artisanal and small-scale gold mining (ASGM) in West Africa has undergone intensification and significant development due to the introduction of increasingly mechanized extraction and processing method. Mechanization generates significant transformations in the socio-technical dynamics of artisanal gold mining. In the specific context of ASGM in Upper Guinea, the article argues that small-scale innovations (ie. ‘low noise’ or ‘low technological level’ innovations) are leading to a profound socio-economic transformation of the rural environment over a long period of time. We begin by describing and analyzing the impact of the introduction of minor innovations (metal detectors, solonins and fan motors) on ASGM practices. We then examine the political, social and economic changes brought about by the adoption of these new mechanized practices, again at the rural level. Finally, we discuss the transition toward a new socio-technical regime, questioning the reshaping of local governance and its impact on new configurations of land ownership and use in rural areas.
