This volume investigates the complex interplay between climate change, human activity, and natural fluctuations in driving global hydrological shifts. Edited by Makoto Taniguchi, a prominent researcher in groundwater and environmental hydrology, the text compiles findings from the 2008 Hydrochange conference. It presents a multidisciplinary framework for understanding how land-use changes and global warming exacerbate the vulnerability of water resources across diverse geographical scales.

Experts recognize this collection as a significant snapshot of hydrological research during the late 2000s, providing a foundational look at the early integration of climate and human-impact modeling. Readers frequently note the technical density of the proceedings, which serve primarily as a reference for researchers and environmental policy analysts.
