Résumé

In Burkina Faso, the Upper Comoé sub-basin has a high potential of water, useful for the development of the population's economic activities. These economic activities create the increase needs of water with conflictual relations between the users the last few decades.This study analyses the water resource management system in the face of the risk of community conflicts in the Upper Comoé sub-basin.The methodology integrates literature review, observation and mixed field surveys. The main results are that the driving force of water conflicts are the decrease of its available quantity, the increasing demand of users and land pressure. Indeed, there is a decrease of the quantity of estimated at 7,284,915 m3 (17%) compared to the total demand of the user groups (43,398,317 m3). The relics of riparian formations, once useful for protecting the banks of water surface, have regressed by 4.8% to the benefit of shrubby savannahs (0.9%) and rainfed crops (0.9%) between 1990 and 2020. This degradation of the flora of the banks, linked to the high demand for land, is perceived by 58% of the respondents. To fix the problem, the local communities have created Local water committees. These committees use a water allocation system. At this step, some improvements are necessary, but going from land restoration and riverbank protection actions, these Local water committees are already relevant actors for conflict prevention and equitable water sharing.
