Resources Roundtable
A national collaboration of federal,
state, local, corporate, non-profit
and academic interests
SWRR Progress
A conceptual framework for understanding the
world
Principles, criteria and indicators to support
decision-making
Collaboration on research needs
Principles of Water Sustainability
1. The value & limits of water
People need to understand the value and
appreciate the limits of water resources
and the risks to people and ecosystems
of unbounded water and land use
Principles of Water Sustainability
2. Shared responsibility
Because water does not respect political
boundaries, its management requires
shared consideration of the needs of
people and ecosystems up- and
downstream and throughout the
hydrologic cycle
Principles of Water Sustainability
3. Equitable access
Sustainability suggests fair and equitable
access to water, water dependent
resources and related infrastructure
Principles of Water Sustainability
4. Stewardship
Managing water to achieve sustainability
challenges us while meeting today’s
needs to address the implications of our
decisions on future generations and the
ecosystems upon which they will rely

Major Categories of Indicators
1. System capacities and their allocation
2. Consequences of water allocation
3. Effects on people
4. Underlying processes and driving forces
5. Composite sustainability assessment
System capacities and their
allocation
1. Gross water availability
2. Total withdrawals for human uses
3. Water remaining in the environment after
withdrawals and consumption
4. Water quality in the environment
5. Total capacity to deliver water supply (i.e.,
infrastructure capacity)
6. Social and organizational capacity to manage
water sustainably
Consequences of the way we
allocate water capacity
7. Environmental conditions
8. Resource conditions
9. The quality and quantity of water for human
uses
10. Resources withdrawals and use
Effects on people of the conditions
and uses of water resources
11. Human conditions – measures of the value
people receive from the uses of water and
the costs they incur, including health effects
Underlying processes and driving
forces
12. Land use
13. Residual flows – the flow of water and wastes
back into the water system
14. Social and economic processes – the systems
people and organizations develop to influence
water resources and sustainability
15. Ecosystem processes
Composite sustainability
assessment
16. Water use sustainability – in each watershed,
the ratio of water withdrawn to renewable
supply
17. Water quality sustainability – in each
watershed, indicators of the suitability of water
quality for the uses desired, including
ecosystem uses

local levels
describing the need for programs to collect the
information necessary for generating indicators
Increase representation
–
incorporating indicators of regional water
management programs
Future Work, cont’d
