A review on the effects of land use on water quality and use: a case study of River Romi in Kaduna State

Abstract

Rapid changes in land use have been shown to have high impact on water quality and use. Access to portable water is necessary for all life and therefore, it is of paramount importance to investigate issues surrounding water availability and its usage. In this review, the effects of land use on the water quality of the River Romi in Kaduna State, Northwest Nigeria have been reviewed. This river is being utilised as a source of water for domestic and industrial consumption as these needs are not being met with any alternatives by the Nigerian government. However, literature has shown that rapid population increase and industrialisation have resulted in high levels of water contamination. Consequently, both physicochemical and biological parameters are above acceptable limits reported by researchers. It is recommended that best management practice (BMP) that uses different techniques such as source control, permeable paving using pervious concrete, storm water detention, storm water infiltration and vapour- transpiration in the treatment of wastewater be employed to reduce waste concentration going into the River, thereby lowering the risk of public health issues. Furthermore, it is recommended that Nigerian government agencies strictly impose regulatory sanctions to ensure effective waste management disposal.
