Integrative One Health Surveillance for Antimicrobial Resistance - IOSAR

We integrate fieldwork, microbiology and big data to understand microbial communities, co‑design interventions and generate evidence that drives changes in policy and practice.​

Why IOSAR Exists

IOSAR brings science, communities and agriculture together to tackle antimicrobial resistance (AMR) at its roots. We study the hidden microbial journeys across soils, farms and food chains to drive smarter policies, safer practices and stronger futures.

Ambition

Build climate- and equity-aware interventions that reduce risk and improve resilience across the supply chain.

Design for impact, measure for truth.

Gap

AMR can't be tackled in isolation - microbes, environments and human behaviour are interconnected. IOSAR generates joined-up evidence across the food system.

Cross‑Sector Clarity

Problem

AMR threatens food systems, ecosystems and public health, yet evidence remains fragmented. IOSAR connects the disciplines to trace pathways and inform action.

Integrated AMR Solutions

What we're doing

Themes that power IOSAR — each combining field, lab, data and engagement.

Next-generation methods

This theme drives innovation and harmonisation of laboratory, field and data‑science methods to generate consistent, high‑resolution insights into AMR pathways.

Community of Practice and Intervention Design​

A cross‑country community of practice brings farmers, practitioners and researchers together to co‑develop evidence‑informed interventions and strengthen day‑to‑day practices across farms and communities.​

Community and Farm Microbial Pathways

IOSAR explores how microbial diversity and farming practices shape the movement of organisms across farms and communities, revealing the pathways that can also contribute to AMR risks.

Fieldwork & pilots

Where the work breathes: fieldwork meets real‑world impact and turns evidence into practice.​

Outputs & impact

Selected metrics and publications. We prioritise clarity, openness and reuse.
