This are the lake and Man made lakes in the word that are playing a role in supplying water and generating hydro-electricity to the continent especially lakes in Africa. The involvement of human activities results in the shrinkage of the lake due to utilisation of resource without caring about the service that the lake provides to the environment. Most of the lakes are no longer support wildlife like before, because of activities that are occurring around the lake. For example recreation and farming they play a part in reducing the wildlife in the lakes. This need a management control, so that the resource that are left can be conserved.
