TL;DR: In this article, the authors discuss the needs and benefits for a system that would monitor and predict the Earth's terrestrial water, energy, and biogeochemical cycles, and they call upon the international hydrologic community and the hydrological science support infrastructure to endorse the effort.

TL;DR: In this article, the authors quantify globally the amount of non-renewable or nonsustainable groundwater abstraction to sustain current irrigation practice and show that non-rechargeable groundwater abstraction contributes approximately 20% to the global gross irrigation water demand for the year 2000.

TL;DR: The model used to assess the future development of the glaciers and the runoff using an ensemble of downscaled climate model data in the Langtang catchment in Nepal shows that both temperature and precipitation are projected to increase which results in a steady decline of the glacier area.

TL;DR: Wada et al. as discussed by the authors assesses global water stress at a finer temporal scale compared to conventional assessments, using simulations of monthly river discharge from the companion paper, which is confronted with global monthly water demand, defined as the volume of water required by users to satisfy their needs.

TL;DR: In this paper, different types of hydrological triggering systems for debris flows, shallow and deeper landslides, are described, and the assessment of meteorological threshold conditions for shallow landslides (1-2 m) needs more detailed meteorological information than for deeper ones (5-20 m).
