Projection and adaptation of tick threat in agricultural and forest landscape under climate change

Project leader: Karine Chalvet-Monfray (UMR EPIA), Laurence Vial (UMR ASTRE)

Project summary:

Climate change modifies phenology and distribution of ticks and thus tick-borne diseases. The objectives of CLIMATICK are: (i) to project the spatial and temporal patterns of future tick activity under RCP scenario, (ii) to propose adaptations of the communication, surveillance and environmental management strategy to improve prevention.

CLIMATICK focuses on the current risk represented by the native ticks (Ixodes ricinus) and its pathogens and on new risk represented by exotic potentially invasive ticks from warmer area, such as Hyalomma marginatum, vector of CCHF. Using longitudinal observational and experimental data, it aims to develop mathematical dynamic and statistical models for tick activity taking into account weather variables, host populations and forest distribution. Projection in future climate will be done for 2050 and 2100. To provide key recommendations, we will study how tick threat is perceived and anticipated in contrasted geographical areas. We will exchange with stakeholders at a national level to identify priority actions previously numerically tested on surveillance, environmental management and institutional communication.
