The One Health approach within risk assessment agencies: Empowering transformation strategies for the benefit of planetary health

In view of the “One Health, One Science” Symposium and the “One Health Summit” which will take place in Lyon, France on the 6th and 7th of April 2026, the ANSES Scientific Board has produced and published a position statement entitled “The One Health approach within risk assessment agencies: Empowering transformation strategies for the benefit of planetary health.” The role of the ANSES Scientific Board is to guarantee the quality, relevance and consistency of the Agency’s scientific work in light of public health issues and the developments in this field. Renewed in 2023, the Scientific Board, which is independent of the Agency's operational bodies, is composed of 24 scientists recognised in Europe and around the world. This statement is reproduced here in its entirety.

In the context of the triple planetary crisis (climate change, biodiversity loss and pollution) and of the scarcity of economic resources, the need for resilient collaborative strategies is urgent. Every day, complex alarming messages on various sources of concern such as persistent pollutants, threatening foodborne pathogens, widespread (micro)plastic dissemination, invasive species introductions, climate change or enhanced natural hazards are echoed by the media. Risk factors cannot be considered for their sole impact on human beings: their impacts must also be assessed on animals, plants, water, soil, air, and the global environment, taking into account the societal dimension and appropriate timeframes. This is the “One Health” approach as defined by the “One Health High-Level Expert Panel”1

One Health is an integrated, unifying approach  that aims to sustainably balance and optimize  the health of people, animals, and ecosystems. It  recognizes the health of humans, domestic and  wild animals, plants, and the wider environment  (including ecosystems) are closely linked and  interdependent.  

The One Health approach urges us to rethink of how health, ecosystems and human activities are interconnected and should be addressed together.

Risk assessment shall rely on robust and independent science, including social and human sciences, in order to align citizens and decision makers on adaptation and transition measures rather than enforcing abrupt and possibly unpopular change. This imposes on public bodies assessing health risks to invest in the long term on relevant research to anticipate risks and therefore shift priorities from crisis management to prevention, preparation and anticipation with the involvement of all stakeholders (civil society, private sector and others).

In this context, the role of scientific institutions is not only to assess risks but also to help policy makers and societies navigate complex transitions by providing independent, longterm and interdisciplinary scientific perspectives.

Public risk assessment agencies have a particular responsibility to support evidencebased decision-making in situations where environmental, animal and human health challenges intersect. the United Nations (FAO), United Nations Environment Programme (UNEP), World Health Organization (WHO) and World Organisation for Animal Health (WOAH).

In France, ANSES, the Agency for Food, Environmental and Occupational Health & Safety, has long been following a multidisciplinary operational approach to One Health challenges. Its Scientific Board, which includes French, European and international experts, supports and encourages ANSES to keep the momentum and achieve its One Health ambition, building on internal resources and external partnerships in Europe and beyond and via key networks such as the European One Health Association (EOHA).

Scientific Experts must move from the traditional way of working in vertical disciplines, in silos, towards multidisciplinary, cross-sectoral
approaches to better assess risks, and recommend solutions in a holistic way.
