| Zusammenfassung |
| This paper presents a preface to this Special Issue on the results of the
QUEST-GSI (Global Scale Impacts) project on climate change impacts on
catchment scale water resources. A detailed description of the unified
methodology, subsequently used in all studies in this issue, is provided.
The project method involved running simulations of catchment-scale hydrology
using a unified set of past and future climate scenarios, to enable a
consistent analysis of the climate impacts around the globe. These scenarios
include "policy-relevant" prescribed warming scenarios. This is followed by
a synthesis of the key findings. Overall, the studies indicate that in most
basins the models project substantial changes to river flow, beyond that
observed in the historical record, but that in many cases there is
considerable uncertainty in the magnitude and sign of the projected changes.
The implications of this for adaptation activities are discussed. |
