Antimicrobial resistance (AMR) is a global human, animal, plant and environment health threat that needs to be addressed by every country. The impacts of AMR are wide-ranging in terms of human health, animal health, food security and safety, environmental effects on ecosystems and biodiversity, and socioeconomic development. Just like the climate crisis, AMR poses a significant threat to the delivery of the 2030 Agenda for Sustainable Development. The response to the AMR crisis has been spearheaded through the global action plan on antimicrobial resistance (GAP-AMR), developed by the World Health Organization (WHO) in 2015, in close collaboration with the Food and Agriculture Organization of the United Nations (FAO) and the World Organisation for Animal Health (WOAH), and formally endorsed by the three organizations’ governing bodies and by the Political Declaration of the high-level meeting of the United Nations General Assembly on AMR in 2016. In 2022, the three organizations officially became the Quadripartite by welcoming the United Nations Environment Programme (UNEP) into the alliance “to accelerate coordination strategy on human, animal and ecosystem health”. The aim of the GAP-AMR is to ensure the continuity of successful treatment with effective and safe medicines. Its strategic objectives include: • improving the awareness and understanding of AMR; • strengthening the knowledge and evidence base through surveillance and research; • reducing the incidence of infection through effective sanitation, hygiene and infection prevention measures; optimizing the use of antimicrobial medicines in human and animal health; and • developing the economic case for sustainable investment that takes account of the needs of all countries and increasing investment in new medicines, diagnostic tools, vaccines and other interventions. With the adoption of the GAP-AMR, countries agreed to develop national action plans (NAPs) aligned with the GAP-AMR to mainstream AMR interventions nationally. Individually, the Quadripartite took action to advance AMR interventions in their respective sectors. FAO adopted a resolution on AMR recognizing that it poses an increasingly serious threat to public health and sustainable food production, and developed an AMR action plan to support the resolution’s implementation. For its part, WOAH developed a strategy on AMR aligned with the GAP-AMR, acknowledging the importance of a One Health approach to AMR. Similarly, more recently, UNEP’s governing body, the United Nations Environment Assembly, recognized that AMR is a current and increasing threat and a challenge to global health, food security and the sustainable development of all countries, and welcomed the GAP-AMR and the NAPs developed in accordance with its five overarching strategic objectives
