This poster, presented at the World One Health Congress 2026, shares findings from an analysis of where climate stress, antimicrobial resistance (AMR) and antimicrobial use (AMU) overlap in food animal production across low- and middle-income countries (LMICs).
The study combined indicators of warming, humid heat and extreme rainfall with data on AMR and AMU in terrestrial and aquatic food animals. Using spatial modelling at a 10 × 10 km resolution, it identified hotspots where these pressures converge, providing evidence to inform targeted, context-specific interventions.
The analysis estimated that 16.4% of cattle, 35.8% of chickens and 23.2% of pigs in LMICs are reared in high-risk climate–AMR hotspots. Terrestrial hotspots were concentrated in northern and western South America, the Middle East, South Asia and eastern China. Animal density was the strongest predictor of terrestrial hotspots, while human population density was the leading predictor in aquatic systems.
The poster identifies three priorities for action: strengthening antimicrobial stewardship and veterinary services where AMR and AMU hotspots overlap; strengthening AMU regulation where use is high relative to herd size; and investigating environmental transmission where AMR is high despite lower AMU.
