Answer:
(2001), water resources in most of the sub-catchments in the Limpopo River basin are impacted by the following: Mining and minerals processing. Landfills and solid waste disposal sites. Disposal of liquid and effluent.
Human activities such as mining, pollution, minerals processing, landfills, etc have an effect on the flow pattern.
It should be noted that pollution is usually difficult to control because it is often the result of human infrastructure around a river.
For example, sewage and effluent are discharged into rivers in some areas and this can lower the pH of the water, and hence affect the organisms.
Also, human activities such as mining, pollution, minerals processing, landfills, impact negatively on the quality of water and the flow pattern in the upper reaches of the blood river in Limpopo.
