Hydrological restoration in two target areas (a series of villages north of Seguela, and Tortiya in Côte d’Ivoire) that result from small-scale diamond mining. Artisanal and small-scale mining typically involves non-mechanized extraction of diamondiferous gravel by individuals or groups. Collectively the impact can be very consequential.
The core problem is negative hydrological effects of ASM mining. Causes include dumping sediment into stream bodies, diverting waterways and destroying water channels. Possible solutions include preventative techniques like land-use planning and training on strategies to mitigate damage to water flow patterns. Post-mining solutions include reconstituting water flow in ways that restore a “natural” flow or contributes to some new land-use (like fish farming and rice farming).
