Le Bassin Versant de Ono (BVO), dans la région du Sud Comoé, est dominé par les cultures agro-industrielles utilisant des fertilisants chimiques. Cela constitue une source importante de pollution, particulièrement aux nitrates. Cette étude visait à modéliser le transfert des nitrates vers les eaux de surface du BVO en deux étapes: (i) modéliser l’érosion hydrique de la zone et (ii) estimer la quantité d’azote dans le BVO. La combinaison de ces paramètres de vulnérabilité, précédée d’une analyse multicritère, a permis d’obtenir une carte des risques de transfert des nitrates vers les eaux de surfaces. Cette cartographie révèle que les classes de Risques Faible et Très Faible représentent 65,5% du BVO. Les classes de Risque Elevé représentent...
