Dynamics of the GWS
GWSP – Central Tenet
Human-induced changes to the global
water system are now globally significant
and are being modified without adequate
understanding of how the system works
The Global Water System
Working definition
The global suite of
water-related
human, physical,
biological, and
biogeochemical
components and
their interactions.
BIOLOGICAL &
BIOGEOCHEMICAL
COMPONENTS
e.g. species richness,
habitat quality,
water quality
PHYSICAL
COMPONENTS
e.g. moisture transport,
precipitation,
river discharge,
water storage
WATER
CYCLING
HUMAN COMPONENTS
e.g. water related institutions,
water engineering works,
water use sectors
ESSP Projects
BALTEX
GWSP Research Niches
 Focus
on global environmental change
 Science driven but policy-relevant
 Global perspective, taking local- and
watershed processes into account
 Broad temporal perspective
(Past-present-future time domains)
 Interdisciplinary & integrative
 Focus on fresh water
Goals & Vision
 Gain
a new understanding about the
global water system
 Refine society‘s view of water
 Create a vision of future possible states of
the global water system

Overarching Question
How are human actions changing the
global water system and what are the
environmental and socio-economic
feedbacks arising from the anthropogenic
changes in the global water system?
Framing Questions (Themes)



What are the magnitudes and key
mechanisms of anthropogenic and
environmental changes in the GWS?
What are the main linkages and
feedbacks within the Earth system,
arising from changes in the GWS?
How resilient and adaptable is the
GWS to change, and what are
sustainable management strategies?
Mechanisms by which humans are
affecting the GWS
reservoirs, withdrawal,
transfers
resulting in
stop-flow events,
changes in nutrient and
sediment fluxes etc.

Conclusion
Global Water System Project
 Consolidate various efforts into a unified,
dynamic research programme
 Broaden knowledge about the GWS
changes; linkages & feedbacks; resilience and adaptive
capacity

Establish monitoring indicators
 New numerical models, GWSP database
 Synergy effects in GWSP-BALTEX co-operation
