Sediment Yield on Different Agricultural Land use Types in Ikpoba Okha, Nigeria (Published)
This work is an assessment of variations in the rate of sediment yield from different agricultural landuse types in Ikpoba Okha. The research design adopted in this study was based largely on direct field measurement. To generate the data required to accomplish the philosophy of this work, measurement of rainfall amount (mm), rainfall intensity (mm/hr) and sediment load (kg) were generated from the months of March to October 2019. The collected data were analyzed using percentages and degree. It was discovered that the rate of sediment yield was determined by the amount of rainfall and that the rate sediment yield on different landuse types vary widely due to the nature of man environment interactions. The sediment yield from bareland (26.9kg) was greater than fallow land (12.8kg) and that of vegetated land was (4.2kg). In order to protect the environment from erosion (sediment yield), the adoption of environmental education is recommended to track down the rate of sediment yield in the study area. An acceptable way for checking erosion over the affected land surfaces especially the bareland is to cover them with grasses mostly during the rainy season. Finally, this study suggests that man environment relationship should be minima so as not to jeopardize the ecosystem and this can only be achieved through formulation of bye-laws and policies that will guide the use and misuse of the land.
