Drivers, challenges, and opportunities around construction-sand mining in Sub-Saharan Africa

Abstract:

Construction sand is the most used solid material on Earth and is central to developing societies and economies. In recent years, the increasing focus on global sand scarcity has highlighted the challenges it poses and the environmental consequences of its extraction. However, comprehensive research describing the complexity of sand mining in lower-income nations is lacking. Currently, there is limited research on understanding the consequences and benefits of sand mining and how these activities directly and indirectly support local communities in a Sub-Saharan context. In this talk, I argue that more work is needed to better understand the paradoxes and nuances of how sand extraction alters the environment, while recognizing that the extraction itself is shaped by socio-economic, political, and financial relations. These dynamics are rapidly evolving across large parts of Sub-Saharan Africa.
