Ecological Engineering to Mitigate Eutrophication in the Flooding Zone of the River Nyong, Cameroon

Abstract

The problems of pollution caused by liquid and solid waste, as a result of the demographic and socioeconomic development along the River Nyong, as well as the climatic conditions and particularly the irregularity of the rains, have repercussions on the quality of the water resources of the said River.

Population growth within the River Nyong’s basin has led to exacerbated deforestation, recurrent pollution, and sedimentation of the river bed. It follows that sedimentation accentuates the growth of floating macrophytes and in turn causes a gradual reduction in the flow of the river and unprecedented damage to its ecosystem as well.

These complex interactions between uses and ecological functions are therefore at the heart of the challenges of the sustainability and balanced management of the River Nyong’s aquatic ecosystem. To manage these interactions, it is therefore essential to understand them, to better control them, and finally to find solutions to better reconcile the uses and natural functioning of this ecosystem.

This is the main purpose of the ecological engineering which is applied for this work using Tchouaffé’s theory of change (TToC) approach, combining Risk, Attitudes, Norms, Abilities and Self-regulation (RANAS) approach and Voyelles approach to build up a framework of active actors aiming at overcoming eutrophication through renaturation or creation of buffer zones. By building a more widespread and better understanding of the consequences eutrophication has on aquatic ecosystems, it is hoped that this chapter will help in fostering stronger collaboration in saving rivers by reducing the global burden of these concerns.
