Abstract
The environmental and socio-economic impact of erosion in Nigeria is huge and well-known to international organizations including the United Nations. Although gully erosion is a serious problem in south eastern Nigeria, it does not affect all the states in the region equally. While Abia, Anambra Enugu and Imo states are severely affected, Ebonyi state is mildly affected. It is shown in this paper that geology and nature of soils underlying the areas, rather than the level of human activity, are the main reasons for the difference in severity. It is emphasized that even the smectite-rich soils covering major parts of Ebonyi state are less prone to gully erosion than the loosely consolidated coastal sands covering the other states. Multiple potholes are a constant distinguishing feature on the smectite-rich roads but not gullies. Most adults do not have proper understanding of sediment disaster nor do they want a career in geo-disaster related discipline. This paper theorizes that apathy and ignorance will hinder any effort at erosion control; and perpetuate the negative impacts of erosion in the area for a long time to come.
