Droughts can have strong environmental and socio-economic impacts in the Mediterranean
region, in particular for countries relying on rain-fed agricultural production, but also in areas …

The time that water takes to travel through the terrestrial hydrological cycle and the critical
zone is of great interest in Earth system sciences with broad implications for water quality …

Accumulating evidence highlights increased mortality risks for trees during severe drought,
particularly under warmer temperatures and increasing vapour pressure deficit (VPD) …

Water stable isotopes (18O and 2H) are widely used as ideal tracers to track water through
the soil and to separate evaporation from transpiration. Due to the technical developments in …

Root access to bedrock water storage or groundwater is an important trait allowing plant
survival in seasonally dry environments. However, the degree of coordination between …

In view of future changes in climate, it is important to better understand how different plant

Maximizing agricultural production on existing cropland is one pillar of meeting future global
food security needs. To close crop yield gaps, it is critical to understand how climate …

Aridity—the ratio of atmospheric water supply (precipitation; P) to demand (potential
evapotranspiration; PET)—is projected to decrease (that is, areas will become drier) as a …

The intensity and frequency of droughts events are projected to increase in future with
