IMPACT OF ANTHROPOGENICS ACTIVITIES ON THE WETLANDS OF KAMBO AND LONGMAYAGUI RIVERS (DOUALA)

Demographic change is responsible for the degradation of wetlands Douala. The overall objective of the study is to analyze the impact of uncontrolled human impact on the lives of people and vegetation located in the neighborhoods of Kambo and Longmayagui rivers (Douala). Interviews with heads of district and surveys of the local population have been made. In total 1 314 boxes were counted (125 boxes in Kambo and 1 189 boxes in Longmayagui). Seventy-five people were surveyed in Kambo (60 %) and 450 people in Longmayagui (37.84 %). The local population is mainly originally from western Cameroon. The main reason she moved into these areas is poverty. She practices mainly agriculture on the banks of Longmayagui and Kambo rivers and dump all their waste into rivers. The plants are invasive and regularly cleared it. These plants are useful to local residents for food and traditional medicine. The management of these areas is not a matter for policy makers but each riparian without any help is doing in managing its space. The interviews and surveys have highlighted the complexity of interactions between actors. Respondents are aware: they identify the environmental, social, political and territorial raised by the management of risk areas.
