In the agro pastoral areas of West Africa crop residues are a common property resource grazed by free-roaming village or transhumant livestock during the dry season. New crop management practices based on recycling of crop residues as compost or their use in conservation agriculture are promoted by research and development programs in order to improve soil fertility. These practices can potentially improve crop yields for individual farmers but can also lead to conflicts for the access of this resource, especially between non-livestock owners and livestock owners. AMBAWA (Agent-based Model of Biomass flows in Agropastoral areas) allows representing the flows of biomass between crop and livestock systems at the field, farm, and village scales in order to assess the effect of innovating management practices on farm productivity in West Africa.
