The development of gullies and other forms of erosion have become the greatest environmental hazard and disaster rampant in southeastern Nigeria. Gully erosion is most often triggered or accelerated by a combination of inappropriate land use and extreme rainfall events. Geophysical methods such as electrical resistivity techniques has been the most used method in investigating gully erosion prone zones in southeastern Nigeria. Through productive review of existing research this study presents a comprehensive review of the causes and environmental impacts of gully erosion as well as control measures aimed at reducing and mitigating the threats posed by gully erosion within the region. From the study the major causes of gully erosion within the study area include both natural and anthropogenic sources. The study concludes that the most problem of gully erosion in southeastern Nigeria is damage to footpaths, roads and properties, while the least is loss of biodiversity. While control measures have been highlighted to mitigate the causes of gully erosion challenges in the area. These include diversion banks to divert runoff to a stable outlet to ease the flow run-off and stabilization walls should be constructed to prevent the encroaching endemic gully erosion from cutting the road, cultivation of vegetative cover and intensive community based campaigns were advised to minimize and control gully erosion.
