At the time the research was undertaken, each interviewee's most recent ASM experience was tied to work linked to plots that are part of an elaborate tributor system in place for alluvial diamond mining, overseen by the Ghana-based company, Great Consolidated Diamonds. The women interviewed, however, no longer mine diamonds.
Human activities can modify floodplain storage by: hydrologically and/or geomorphically disconnecting channels and floodplains; altering fluxes of water and sediment to the river corridor; and obliterating floodplains through alluvial mining or urbanization.
