The wetlands whose marshes are currently under pressure from the growing population require a consequent increase in production. The marshes are now agricultural reserves coveted because, firstly, the scarcity of arable land, of the other problems of erosion and soil fertility decline affecting land in hills uphill. The mostly poor people resort to these marginal lands, to the suppression of fallows and to afforestation. This results in overexploitation that accelerates the degradation of soil and biological and abiotic resources. However, farmers do not have the knowledge and technologies to enable them to sustainably manage wetlands. The results of this study show that the population of our study area is largely dependent on marshes for drinking and irrigation water supply, building and basketry materials, and plant species to feed the farm animals. The majority of farmers have a portion of land in the marshes. The main crops are currently leguminous and tuberous plants with rice and beans which are successively the most productive crops. The majority exploit the marshes in both dry and rain seasons. The marshes provide 78% of the farmers with an average income between 0 and $ 30 per plot/season. The income is very low given the needs of farmers. These activities have resulted in the disappearance of the original fauna and vegetation of these marshes more than 13 years ago. The results of the study led us to conclude that these marshes were dominated by Cyperus papyrus . The draining of marshes has led to the drying up of springs, the loss of many animal and plant species.
