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.

Abstract: (french)
L’évolution démographique est responsable de la dégradation des zones humides de Douala. L’objectif général de l’étude est de déterminer l’impact de l’anthropisation anarchique sur la vie des habitants et la végétation situés aux voisinages des rivières Kambo et Longmayagui (Douala). Des entretiens auprès des chefs de quartier et des enquêtes auprès de la population riveraine ont été effectués. Au total, 1314 cases ont été comptées (125 cases à Kambo et 1189 cases à Longmayagui). Soixante-quinze personnes ont été enquêtées à Kambo (60 %) et 450 personnes à Longmayagui (37,84 %). La population riveraine est majoritairement originaire de l’Ouest-Cameroun. La principale raison pour laquelle elle s’installe dans ces zones est la pauvreté. Elle pratique principalement l’agriculture sur la rive des rivières Kambo et Longmayagui et déversent tous leurs déchets dans les rivières. Les plantes y sont envahissantes et régulièrement défrichées. Ces plantes sont utiles aux riverains pour l’alimentation et la médecine traditionnelle. La gestion de ces zones n’est pas l’affaire des décideurs publics mais chaque riverain sans aucune aide se débrouille dans la gestion de son espace. Les entretiens et les enquêtes ont fait ressortir la complexité des interactions entre les acteurs. Les enquêtés en sont conscients : ils identifient les enjeux environnementaux, sociaux, politiques et territoriaux soulevés par la gestion des zones à risque.
