My doctoral project assess the effects of the ongoing agricultural transition in the peri-urban landscape. The aim of this research proposal is to suggest a method to fill in the gaps and provide increased knowledge of landscape change and the eco-epidemiological aspects of peri-urban green areas used for recreation. In this project, I will focus on Ixodes ricinus, one of the principal vectors of pathogens causing arthropod-borne infections in Europe.

Specific aims:
• To analyze biodiversity and ecosystem (dis) services of peri-urban landscapes, with
emphasis on the tick Ixodes ricinus and its tick-borne diseases.
• To analyze drivers of land-use change by looking at effects of horse-keeping on peri-urban ecosystems and tick distributions.
• To analyze how conservation management of peri-urban green areas effects spread of ticks.
• To assess different human utilization and recreational activity risks for ticks and tick-borne diseases.
