Explore frontiers in ecohydrology through this AGU lecture by Dr. Simone Fatichi from the National University of Singapore. Delve into the roots of ecohydrology, moving beyond equidrology with case studies and observational comparisons. Examine model confirmations, experimental results, and the drought paradox. Investigate the effects of CO2, land-atmospheric interactions, and management scenarios. Learn about data interpretation techniques, machine learning applications, and above and below ground processes in ecohydrology. Discuss challenges in the field, including data gaps and heterogeneities. Gain insights into the future of ecohydrology and its impact on understanding complex environmental systems.
