Session Proposal: Intersections of Ecology, Hydrology, and Climatology in Earth’s Drylands (AGU25)

B056
Intersections of Ecology, Hydrology, and Climatology in Earth’s Drylands

Session ID#: 249496

Session Description:
Drylands cover 41% of Earth’s land surface, host 60% of global agriculture, and support 35% of the human population. They are also exceptionally vulnerable to global change, in part because of the interconnectedness of dryland climatology, hydrology, and ecological dynamics. Accounting for cross-scale linkages among these key components of dryland functioning is crucial for predicting impacts of climate and land-use change. In this session, we seek to: 1) highlight advances in our understanding of the connections among dryland ecology, hydrology, and climatology, 2) identify new approaches to quantify and characterize those connections across space and time, and 3) address dryland-specific challenges, including those related to spatial heterogeneity and temporal pulse responses. We invite submissions from researchers examining linkages between/among any combination of dryland ecology, hydrology, and climatology, in natural or managed ecosystems. We welcome observational, experimental, modeling, or remote sensing perspectives across a wide range of fields.
