The impact of antimicrobial resistance extends beyond the farm-level to other stakeholders warranting the need for a collaborative approach to combat antimicrobial resistance while optimising production objectives and safeguarding human health.

A study published in Frontiers in Veterinary Science (July 2023) mapped out the effect of antimicrobial resistance originating from poultry production in Senegal and highlights the entry points for interventions from a stakeholder perspective.

A causal loop diagram was developed following a group model building procedure with 20 stakeholders and integrated with network analysis by translating the causal loop diagram into an unweighted directed network.

Results indicate that with an eigenvector centrality of 1, 0.85, and 0.74, the production cost, on-farm profit, and on-farm productivity, respectively are the most ranked influential variables driving the complexity of antimicrobial resistance in the poultry production system.

Two reinforcing feedback loops highlight the dual benefits of improving on-farm productivity and increasing on-farm profit.

However, one balancing feedback loop that revolves around the causal link between producers’ investment in qualified human resource personnel to ensure good farm management practices underline the financial implication of producers’ investment decisions.

The findings provide precursory groundings for the development of a quantitative system dynamic model, the formulation of intervention scenarios and ex-ante impact assessment of the cost-effectiveness of the interventions.
