Description du projet
Analyser la restauration des écosystèmes pour minimiser le risque de débordement zoonotique
Selon l’Organisation mondiale de la santé, la transmission d’agents pathogènes de l’animal à l’homme (débordement zoonotique) est la cause prédominante des maladies infectieuses émergentes et la cause principale des récentes pandémies. Un nombre croissant d’études ont établi un lien entre le risque de débordement zoonotique et la dégradation du paysage causée par l’homme. La restauration pourrait par conséquent être une solution logique. Nous ignorons toutefois les mécanismes par lesquels la restauration pourrait protéger contre la propagation, les échelles spatio-temporelles nécessaires, le type de restauration nécessaire ou les effets potentiels sur la façon dont les humains interagissent avec l’environnement et si cela peut augmenter le risque de débordement zoonotique. Le projet RESTOREID, financé par l’UE, étudiera l’impact de la restauration sur les maladies de la faune et les risques émergents de débordement.
Objectif
Restoring Ecosystems to Stop the Threat Of (Re-)Emerging Infectious Diseases: There is a growing body of evidence that landscape degradation is linked to zoonotic spillover risk. Large scale restoration is increasingly being touted as an effective solution for mitigating against a range of anthropogenic impacts and is also hypothesised to protect against zoonotic disease spillover. However, little is known about the mechanisms with which restoration may provide this protection. It is commonly assumed that restoration mirrors in reverse the processes that occur during degradation; however, it is likely that this relationship is in fact asymmetric. Rarely can restored landscapes be returned to a state similar to that of pristine ecosystems, and often restored landscapes need to fulfil a range of environmental and socioeconomic requirements that inherently prevent them from doing so. Additionally, the spatiotemporal scale necessary to effect positive change is context dependent, and the type of restoration necessary to protect against zoonotic spillover is currently unknown. Ecosystem restoration can vary widely in type, scale and context and can also change how humans interact with their environment, which may have unexpected consequences for zoonotic disease spillover. Given the complexity of these interactions and their effect on disease, it is vital that we understand how restoration specifically might impact wildlife disease and emergent spillover risk.
