Article

Both hydrology and geomorphology of Atikeke stream, a sub drainage basin of Asa River in Ilorin has been impacted by in-stream sand mining activities. The uncontrolled sand excavation which began almost four years ago in the river channel is being largely carried out to meet civil construction needs induced ~y rapid economic growth and high urbanization rate in the city. The study observed that the estimated 10,125 tons of sand being yearly excavated from the study channel is seriously impacting negatively on the hydro-geomorphic environment of the catchment. Though sand mining activities in the study area have both economic and social benefits, the activity is observed to be a destructive development endeavour where physical environment including ecology suffer at the expense of economy.
