The flow of the Chang Jiang is some 20 times greater than that of the
Huang He. As much of 40% of China's total grain production, 70% of rice
output, and more than 40% of the population are associated with the
Chang Jiang's vast basin that includes more than 3,000 tributaries. With
its numerous tributaries, the Chang Jiang drains nearly 20% of China's
total area. Its upper reaches tap the uplands of the Tibetan Plateau
before sweeping across the enormous and agriculturally productive
Sichuan Basin that supports nearly 10% of China's total population. It
is in the middle course of the Chang Jiang that the controversial Three
Gorges Dam is being constructed.

The Presidential election in Nigeria in 1999 was significant
because it is the first election after the 1993 coup and it is the first
election of the Nigerian republic. In this election, Olusegun Obasanjo won over
Olu Falae. 62.78% of votes was casted under Obasanjo.
Human activities such as mining, pollution, minerals processing, landfills, etc have an effect on the flow pattern.
<h3>
Effect of pollution</h3>
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.
