Restoring nature's health: Investigating the effects of ecosystem restoration on zoonotic disease risk

Emerging infectious diseases (EIDs) pose a significant threat to global public health. Among the factors contributing to the increase of EIDs today, habitat degradation stands out as a prominent driver, exerting both direct and indirect influences on disease dynamics. While it is commonly assumed that simply reversing ecosystem degradation will restore disease regulation mechanisms, such a presumption may oversimplify the complex response involved. My PhD project aims to delve deeper into the mechanisms underlying the impact of ecosystem restoration on zoonotic disease risk by examining terrestrial small mammal (TSM) and microparasite diversity within sampling sites following a chronosequence of ecosystem restoration in the Congo Basin. Through comprehensive sampling methods, including the capture of TSMs, and collection of iDNA and acoustic samples, the project will investigate how small mammal and microparasite diversity and prevalence evolve over time post-restoration. An emphasis will be placed on a subset of vector-borne and directly transmitted microparasites associated with African TSMs frequently found in the Congo Basin (i.e. Hepaciviruses, Paramyxoviruses, Orthonairovirus, Leptospira, Bartonella, and Anaplasma). The findings of this study will help unravel the complex interactions between ecosystem restoration, biodiversity, and zoonotic disease risk, offering crucial insights for the improvement and safeguarding of human, animal, and ecosystem health. This research is situated within the framework of the RESTOREID project (Horizon Europe; PI: Herwig Leirs), which aims to investigate the role of landscape restoration in mitigating disease risk using various field sites in Europe and Africa.
