Advancing Our Understanding of Global Vegetation Stress and Its Feedbacks With Our Climate System

Session ID#: 159772

Session Description:
Vegetation plays a crucial role in mediating land-atmosphere interactions. However, while changes in temperature and precipitation patterns will affect vegetation water supply and demand, detecting and predicting the impacts of these changes remains challenging. 

Advances in remote sensing, experimental studies, and the growing number of in situ measurements and ecosystem trait databases, can now be combined with machine learning, statistical approaches and mechanistic models, to understand how plants respond to climate extremes. Combining these data in innovative ways will help to validate and improve models of plant-stress, and in-turn climate predictions.

We encourage contributions that advance understanding of vegetation-stress and its climate feedbacks. This includes studies using new techniques for monitoring plant-stress, evaluating and calibrating plant-stress representation in models, improving our understanding of how plant-stress impacts surface fluxes and boundary layer processes, using ecosystem trait data to improve understanding of plant-stress, and investigating plant-stress with changing climate through manipulation experiments.
