This project will investigate the links between biodiversity, infectious disease and human health in a rural community in Madagascar. Research has documented conflicting associations between land use change and infectious disease risk, with some studies finding that deforestation increases disease risk for humans, while other studies find the opposite pattern. It is critically important to make sense of these conflicting patterns. One approach is to design studies that elucidate the mechanisms that drive associations between land use change and infectious disease risk for humans. One such mechanism is that deforestation alters wildlife communities by reducing habitat for native species and introducing invasive species, thus changing the disease dynamics of biological systems. The specific effects of human activities on disease, however, depend on the intensity of land use, the original biodiversity and other factors.
