We call for an urgent consideration of ecological and
evolutionary approaches to understand and model pandemics in a changing
world in order to prevent them. Once again, we argue for
transdisciplinary research conducted under the Ecohealth, OneHealth and
Planetary Health frameworks. To date, these initiatives have been
largely ignored by decision-makers compared to the purely medical
perspective that relies instead on the development of curative methods
to prevent or control pandemics. However, such frameworks can help us
understand the connection between pathogen spread within human
populations, inter-specific pathogen transmission within animal
communities, and how this may lead to adaptation and emergence. The
knowledge generated by this research can therefore greatly improve our
capacity to prevent large-scale pandemics.
However, if such knowledge is not considered today by
decision-makers, our scientific community could be blamed for not having
put the knowledge produced into a “solution-oriented” framework that
could be directly used by authorities. Therefore, we also call on
scientists working on the evolutionary ecology of pathogens to integrate
“solution-oriented“ research, more connected to the field, in order to
devise solutions and practical applications of scientific results,
emulating recent similar movements in the field of economics and other
social sciences 22. Biodiversity conservation,
landscape management and theoretical evolution (among others) could all
be “solution-oriented” research if applied to relevant pathogen
models. Such “solution-oriented” research agendas could improve our
capacity to avoid the next COVID-19-like catastrophe.
