This study focuses on an analysis of water resource management in cities of developing countries with very rapid rates of urbanization. The objectives are twofold: firstly, to highlight the factors which caused and which govern poor water resources management these cities and secondly to develop a coherent sustainable urban water resources management strategy. The study was conducted in the Abiergue watershed in Yaoundé-Cameroon. The methodology used is based on holistic and participative approaches resulting from the combination of principles of "Integrated Water Resources Management-IWRM" and "Ecosystem and Human Health-ECOHEALTH". Political, economic, social, environmental, historical and mesological factors have resulted in a water resources management system marked by many inadequacies and constraints. Poor access to drinking water and sanitation, recurrent flooding, endemic waterborne diseases, water pollution etc are all permanent pressures that contribute to the impoverishment of households and hamper the development of the area in particular and that of the town of Yaoundé in general. The poor water resources management in the Abiergué watershed is an indicator of an urban governance crisis. Three scenarios to improve this situation were developed: maintaining the status quo; destruction of buildings and a scenario based on IWRM and ECOHEALTH. The optimal strategy integrates principles from IWRM and ECOHEALTH with the base scenario 3.4 focused on actors. Using a sequential process, it takes into account actions on water resources, health and reforms on the legislative, regulatory and institutional framework. Many constraints like land tenure, corruption, limited financial resources and poor urban governance may undermine the implementation of this strategy despite the potential of the watershed. All indicators suggest that water resources management in the Abiergue watershed is poor. There is therefore an urgency to implement this strategy within the framework of the ongoing IWRM process in Cameroon. "Time for Solutions", the theme of the 6th World Water Forum held in Marseille in 2012 is fully translated into action through this study. [less ▲]

The area catchment of Abiergué, located in the urban perimeter of Yaounde between 11°05' and 11°25' East longitude and between 3°51' and 3°54' North latitude experiencing an important truck-farming activity in its bottoms funds from Nkolbikok to Nkolbisson. A study started in 2005 in this area, has for main objective to contribute to the enhancement of this activity while working to reduce the involved risks (health and environmental). Many activities have been developed using a transdisciplinary approach. The socio-economic conditions of the actors implied in this die have been described. The constraints and the assets related to the development of the urban truck farming were raised. The wastewater comes from various origins (households, market, health centres,…) and have significant levels of BOD5 (10 to 360 mg O2 /l), COD (15 to 601 mg O2 /l), Fecal Coliform (5025 UFC/100ml to 3 x 106 UFC/100ml), Fecal Streptococci (1960 UFC/100ml to 138 000 UFC/100ml). Variable rates of cysts of protozoa (Entamoeba hystolotica and Giardia sp) and eggs of helminths were detected in this water. The reuse of wastewater has for corollary the emergence of waterborne diseases such as intestinal amebiasis which as well assigns the actors engaged in this die as the population in general independently of sex, age or social status. Many practices and many risk behaviors contribute to the spread of waterborne diseases. Despite the risk of waterborne diseases, this activity contributes significantly to food security, strengthening the economic potential, development of urban space in short to improve conditions and the framework of life of the categories of actors involved in this activity in particular and population in general. Actions economically viable, socially acceptable and ecologically sustainable are to be implemented by State or NGO in order to reduce the negative aspects and strengthen the positive aspects of this multipurpose activity.
