ABSTRACT

This work was carried out with the aim of identifying the causes of erosion problems and the forms of soil erosion existing in Ika environs. Data were collected through reconnaisance survey and questionnaires between 2009 and 2010. Man was identified to be majorly responsible for the erosion problem in IKa envious through his devices activities such as poor constructional works and bad farming practices that exposed the soil to agent of erosion. Twenty eight gully sites were identified and these ranged between 1-300 meters long, 1-20 meters deep and 1-5 meters wide and these were common on steep slopes and exposed area. Though sheet erosion sites were also identified but very normal in all the areas of study. It was therefore suggested that practices that will continually ensure proper protective cover of the soil should be adopted.
