Introduction A rise in vapour pressure deficit (VPD) has become evident in recent decades, due to a significant increase in surface temperature, while surface relative humidity (RH) has declined at the global scale (Vicente-Serrano et al., 2018; IPCC, 2021). Plants sense variations in VPD, defined as the difference between the saturation and actual water vapour pressure, through the leaf-to-air vapour pressure difference (LAVPD).

AbstractThe vapor pressure deficit reflects the difference between how much moisture the atmosphere could and actually does hold, a factor that fundamentally affects evapotranspiration, ecosystem functioning, and vegetation carbon uptake. Its spatial variability and long-term trends under natural versus human-influenced climate are poorly known despite being essential for predicting future effects on natural ecosystems and human societies such as crop yield, wildfires, and health.
