Assessing the risk of diseases with epidemic and pandemic potential in a changing world

How do human activities contribute to the emergence of zoonotic diseases that can lead to epidemics and pandemics? Our analysis of common drivers of the World Health Organization’s priority diseases suggests that climate conditions, including higher temperatures, higher annual precipitation levels, and water deficits, elevate the risk of disease outbreaks. In addition, land-use changes, human encroachment on forested areas, increased population and livestock density, and biodiversity loss contribute to this risk, with biodiversity loss showing a complex and nonlinear relationship. This study also presents a global risk map and an epidemic risk index that combines countries’ specific risk with their capacities for preparing and responding to zoonotic threats. ; JRC.C.6 - Economics of Climate Change, Energy and Transport
