Tick and Tick-borne disease (TBD) risk is dependent on interactions within complex, systemic networks of highly localized social and ecological variables. In the absence of effective programs, risk detection and prevention has become the responsibility of individuals at local scales, making them local actors in identifying and implementing solutions. In this PhD work, Iyonna and her team aimed to gain a holistic understanding of TBD risk from an actor-centered approach within its social-ecological dimensions. Using social science and participatory research approaches, they explored how community actors and researchers could collectively contribute to improving tick risk surveillance, prevention and management in France through transdisciplinary collective action.
