Land-use and land-cover change (LULC), ranging from shifts in vegetation communities and agricultural practices to rapid land management transitions, plays a critical role in modulating ecohydrological processes across multiple timescales. In the shorter term, abrupt changes in irrigation, deforestation, and land management practices can affect flooding, droughts, and heatwaves by altering water cycle dynamics. Over longer timescales, gradual changes like evolving cropping patterns and afforestation can fundamentally impact water availability, carbon fluxes, and nutrient cycling over decades. This session invites presentations leveraging geospatial techniques—including remote sensing, machine learning, or Geospatial foundation models (GeoFMs), isotopic tracing, or modeling frameworks to capture the key ecohydrological impacts over time. Topics of interest include (i) detection and attribution of LULC shifts, (ii) quantification of extreme event frequency and severity in response to vegetation and agricultural dynamics, (iii) long-term trends in groundwater and surface water interactions, and (iv) uncertainty analyses in dataset selection and modeling.
