Influence of Changing Climate Conditions on Agriculture

Location: Bellmont A (Crowne Plaza Portland Downtown Convention Center Hotel)

While focusing on all components of the soil-vegetation-atmosphere system, the objective of this theme would be twofold: 1) discuss the measurement and modeling carbon, water, and other scalar fluxes under both current and future climate conditions; and 2) discuss the implication of changing climate for agricultural and forest management practices, crop productivity, and resource, especially food, security.

Effects of Canopy Structure on Turbulent Transport Part I

Location: Bellmont A (Crowne Plaza Portland Downtown Convention Center Hotel)

Many natural and managed ecosystems – for example, forests, orchards, and vineyards – exhibit significant canopy structure. This structure not only impacts the development and intensity of turbulence within and above the canopy, it also strongly influences the transport of heat, moisture, carbon dioxide, and other scalar quantities. The aim herein is to explore both the unique characteristics of turbulence in complex canopies and the methods for measuring and modeling turbulent transport in these environments.

Identifying and Monitoring the Effects of Agricultural Drought

Location: Bellmont A (Crowne Plaza Portland Downtown Convention Center Hotel)

Several recent studies suggest the occurrence of drought has increased globally. This theme would focus on recent advances in methods for identifying the onset of drought including “flash” droughts, quantifying drought characteristics (severity, duration, geographic extent, etc.), and monitoring its impacts over time through direct observation, numerical modeling, and remote sensing-based approaches.
