One Health Summit side event

Event co-organized by WMP, INRAE and EFSA.

This side event brings microbiomes to the forefront of the One Health agenda, exploring their critical role across the entire food system, from primary production to human wellbeing. Leading experts from science, policy and innovation will come together to discuss how microbiomes shape crop productivity, animal health, food quality and antimicrobial resistance - and how their disruption can amplify risks across ecosystems. By highlighting concrete solutions and pathways to action, the session will showcase how strengthening microbiome health can support resilient food systems, safer food and long-term planetary health. The event will also mark the launch of the Human Microbiome Cohort Alliance, a global alliance coordinated by the World Microbiome Partnership to collect one million human gut samples by 2030.

The transversal nature of microbiomes strongly aligns with the “One Health” approach, serving as a biological links between different ecosystems. Soil microbiomes influence crop resilience and nutritional value; plant and animal microbiomes shape productivity, health, and antimicrobial resistance; while human microbiomes are influenced by diet, environment, and agricultural practices.

Bringing together leading experts from across the One Health spectrum, the session will explore how microbiomes can help reduce antimicrobial resistance risks and influence nutrient cycling, crop productivity, animal health, food quality, and human well-being. It will also examine how microbiome disruption can amplify risks throughout the food chain.

By looking across the entire food system, the event will demonstrate how improving microbiome health in interconnected ecosystems can enhance resilience, contribute to food security, reduce environmental pressures, and promote long-term planetary health. The discussion will also highlight pathways and opportunities to integrate microbiome knowledge into policy, innovation, and One Health decision-making.

The event will also mark the launch of the Human Microbiome Cohort Alliance, a global initiative coordinated by the World Microbiome Partnership (WMP), aiming to collect one million human gut samples by 2030 to establish a global observatory for microbiome health.
