This report provides a comprehensive overview of global water resources for the year 2023, assessing key hydrological variables such as river discharge, reservoir storage, groundwater levels, soil moisture, and snow water equivalent. It examines climatic impacts, including droughts, floods, and heatwaves, and highlights the effects of transitioning from La Niña to El Niño conditions. The report emphasizes how water resource patterns shifted in response to global climate anomalies, drawing from extensive observational and modelled data. Additionally, it offers insights into major hydrological disasters, with a focus on regions like the Americas, Africa, Asia, and Europe, and calls for enhanced data sharing and monitoring to improve global water resource management.
