Measuring the Sustainability of Water Management in the U.S. Minnesota Water 2005 John R. Wells Minnesota Environmental Quality Board & Sustainable Water Resources Roundtable October 26, 2005 Minnesota Environmental Quality Board Governor’s Office (Chair) 5 Citizens Administration Agriculture Commerce Employment & Economic Development Health Natural Resources Water & Soil Resources Pollution Control Agency Transportation Staffed By…. Office of Geographic & Demographic Analysis Department of Administration Sustainable Water 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 General Systems Perspective Biophysical Environment Economic System Social System Ecosystems Fisheries Systems Perspective Biophysical Environment Economic System Economic System for Fishing Social System Aquatic Ecosystem Social System for Fishery Management Ecosystem Processes & Societal Drivers Ecosystems time Disturbance & Response Ecosystem goods & services Economic Development Energy Cycling Hydrologic Cycle & Flow Regime Materials Cycling Social & Economic Drivers: Human alterations & discharges Energy Production and Use Land Use Population Growth Transportation time Natural Processes: Society Indicator Categories Specific Categories for Water-Resources Sustainability Indicators Starting Conditions Environmental Conditions Gross Water Availability Social Capacity Infrastructure Capacity Human Conditions, Social & Economic Processes Alterations of Landform & Stream Morph. Water in the Environment Water Withdrawals For Human Uses: Quantity Quality Processes Water Quality Environmental Processes Ending Conditions Environmental Conditions Water Uses Treatment Treatment Return, Waste and Residual Flows Water Dependent Resources and Conditions Econ. Production Water Dependent Resource Uses Water Dependent Condition Uses Water Dependent Resource Withdrawals Human Conditions Gross Water Availability: Precipitation Social Institutional Capacity: Social Infrastructural Capacity: Water law and rights Regulation of appropriations Drinking water and wastewater treatment capacity Water in the Environment: Net Water Availability: Quality/Quantity streams, lakes, wetlands & aquifers Water available for people Water Withdrawals for Human Uses: Total withdrawals for all purposes Treatment Water Uses And Reuses Treatment Return Flows: Return water & physical, chemical and biological pollutant loading System Capacities and Their Allocation Example Indicators Consequences of Water Allocation Water in the Environment Water Withdrawals For Human Uses Return Flows Water Uses And Reuses: Municipal and industrial use Environmental Conditions: Water quality Biodiversity Water Dependent Resources and Conditions: Fish stocks Aesthetics Water Dependent Resource Harvests: Fish landings Example Indicators Water Dependent Resource Uses: Fish consumption Water Condition Dependent Uses: Sailing Effects on People Value of Goods and Services Produced with Water: Water Uses: Cropland irrigation Value of produce and processed foods Water Dependent Res. Uses: Value of Goods and Services Produced With Resources: Fishing Food & recreational value Water Condition Dependent Uses: Sailing Health Effects: Nutritional value Exposure to toxic chemicals Incidence of drowning Value of Uses Dependent on Water Conditions: Boating expenditures Recreational value Example Indicators Information Pyramid Fewer Pieces Of Information Stories Criteria Indicators More Pieces Of Information Measurements 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 Figure 4.1.1. Available Precipitation Source: S.

Roy, K. Summers and R. Goldstein Collaboration on Research Needs Process research Decision support tools Data inventory Technologies Value of water in policy decisions Better law & policies Human resources Collaboration Outreach 300 active participants from federal, state and local governments; corporations; nonprofits and academia Meetings in California, Minnesota, Michigan, Washington DC, Maryland, Virginia Publications and conference presentations Future Work Complete, revise and refine indicators – Assist agencies – including indicators scalable to national, state and 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 Expand relationships with the scientific community Consult with other programs on water related indicators – – – National Research Council Key National Indicator Initiative Council on Environmental Quality Heinz Foundation Plan a National Forum Contact Information Email: [email protected] www.eqb.state.mn.us http://water.usgs.gov/wicp/acwi/swrr
