Our global Hydrology model PCR-GLOBWB was used by Rens van Beek in support of global studies on water scarcity and land degradation.

Together with PBL Netherlands Environmental Assessment Agency he contributed scenarios in support of the UNCD Global Land Outlook. Find the report here!

And together with the World Resources Institute and Deltares, Rens contributed to an assessment of water scarcity in the MENA region published  in a book by the World Bank. The book Beyond Water Scarcity and be downloaded here!

We published a paper in Nature projecting that under a 1.5  degree warming, as agreed upon under the Paris Agreement, the glaciers in High Mountain Asia will have lost about 35% of their mass. Under more realistic climate scenarios the mass loss could add up to 65%, with dire consequences for people that depend on the melt water runoff of the Asian rivers.

First author Philip Kraaijenbrink has made a nice visual story line of the study.

Some good press coverage: Carbon Brief  The Guardian

In a  new study by Ted Veldkamp (VU Amsterdam), Yoshi Wada  et al. that appeared in Nature Communications it  is shown, by using a multi-model ensemble from ISI-MIP 2a (PCR-GLOBWB among these),  that human interventions in the global water system may decrease water scarcity upstream while aggravating water scarcity downstream.

Former members of our group Yoshihide Wada and Niko Wanders were involved in new high impact publications using PCR-GLOBWB:

Yoshi was co-author on a paper in Nature assessing how groundwater depletion is embedded in international food trade.  See this link for a nice BBC news item.

Both Niko and Yoshi were involved in a GRL paper looking how water management can both mitigate and intensify hydrological drought. The PNAS website had a nice item about this work.

We are happy to announce that Inge de Graaf published a paper about our newly-developed global two-layer transient groundwater model. This version is coupled one-way with the global hydrology and water resources model PCR-GLOBWB. A newer version also has a two-way (at time-step) coupling with PCR-GLOBWB and will be reported on shortly. You can find the paper here!

Furthermore, Yoshihide Wada (vice-director Water at IIASA and senior research associate at UU) and colleagues published a new paper in Nature Geoscience in which they show from analyses of satellite and local well data spanning the past decade that long-term changes in monsoon precipitation are driving groundwater storage variability in most parts of India either directly by changing recharge or indirectly by changing abstraction.
