Vegetation-water interaction plays a significant role in the global carbon cycle and energy balance. Vegetation water stress in different environments is a key in vegetation-water interactions. In this talk, I will discuss vegetation water stress ranging from desert environments to forests, ranging from individual plants to a global scale using stable isotope and remote sensing techniques. The results will highlight the important but often neglected role of fog and dew in dryland ecosystems, identity a new mechanism causing vegetation water stress in forests under acid deposition, and demonstrate the increasing water limitation in vegetation growth across the Northern Hemisphere. The results highlight the importance of understanding and quantification of vegetation water stress to better predict the ecosystem responses to climate change.
