This series of briefs highlights seven key areas and 22 practical action areas that governments, investors, experts in One Health and policymakers can promote and invest in. These areas highlight the linkages and connections between interventions and underscore the need for systems thinking.

# Livestock contribute about 40% of agricultural GDP and provide livelihoods and incomes for at least 1.3 billion people worldwide.

One Health recognizes the interconnection between people, animals, plants, and their shared environment and works across scales for better health outcomes.
The One Health challenge and opportunity
Successful One Health approaches require changes in outlook and action. They demand a shift from a disease-focus to a more systems-based one, rethinking the idea of innovation to embrace new ways of working as well as technological solutions, and sharing learning and evidence.

The 2020-21 coronavirus pandemic alone has killed millions of people and cost billions of dollars in damage and lost livelihoods. It is just the latest example of a previously unknown disease to jump from animals to people. It is unlikely to be the last.
These complex health risks and burdens cross disciplinary, national and species boundaries so traditional, parallel sectoral approaches based around public health, veterinary services or environmental management are inadequate.

One Health approaches work across sectors and scales for better health outcomes for people, animals and the environment.
