The Problem
• Human land use and land management contributes to
(fresh) water quality issues in the Great Lakes
• Rural to Urban Home/Landowners
– Chemical lawn applications (runoff)
– Dumping (stormwater drains, streams)
– Streamside maintenance (mowing, riparian areas)
• Agricultural Landowners
– Land use (cropping choice, crop rotation)
– Land management (nutrient applications, tillage practices)

Water quality risks
• Human health
– Neurotoxins, Skin Irritants, Pathogens
• Environmental health
– Oxygen depletion, Biodiversity, Ecosystem services
• Recreation
– Fishing, Swimming, Boating
• Economic
– Fisheries, Tourism, Property values

Informing Decision Making
• Need to improve knowledge about the issue
– What do people know about stream health and water quality?
– What do people know about human impact?
• Need to frame problem in light of relevant risks
– What motivates stream stewardship decisions?
– What do people care about in regards to poor water quality?

Two Studies
• Mental models methodology
• What do citizens (rural to urban) know about water
quality?
– What are the major influences on their stream stewardship
decisions?
• What do farmers know about nutrient transport?
– What are the major influences on their land management
decisions?

Study I: A study of Ohio citizens
• USDA National Integrated Water Quality project
• Conducted in-depth interviews with 45 central Ohio citizens (ages ranging from 16 to 80)– Probed knowledge about streams, watersheds and water
quality
– Probed influences on stream related decisions
• Currently using findings to design H.S. science curriculum and community-based education and outreach programs

Ecological Knowledge & Related Threats
• Ecological knowledge gaps:– Specialized functions (wetlands, floodplains)
– How streams are formed (topography, flow, watersheds)
– What makes streams healthy (flow, substrate)
• Threat/Impacts gaps:– Channelization, Ecosystem services, Human influence
• Need to communicate: – Change over time to overcome focus on present state
– How healthy streams operate (structurally, functionally)
– Threats/causes/sources, and link between threat and impact
– Influence of human activity & importance of specialized function

Influences on Decision Making
• Drivers of information seeking:– Environmental ethic and changing recreational opportunities
• Drivers of internalization:– Awareness of the problem (due to availability of info and personal
interest) and perception of risks and benefits, and adaptive capacity
• Need to: – Ease the path to information, frame in light of personal interests
(health, property), and include tips for recognizing problems
– Build an ethic/value base around environmental stewardship
– Use recreation to educate/communicate and promote it as a benefit of healthy streams

Barriers to Action
• Pre-internalization barrier:– Benign neglect (lack of concern due to being unaware)
• Post-internalization barrier:– Economic interests (greed, high personal costs)
• Citizens interested in monitoring and management
• Need to: – Communicate about problems that currently exist
– Motivate by focusing on salient risks and benefits (water quality, access/use, human health, aesthetics)
– Focus on actions not limited by economics
– Communicate what needs to be done and how to do it

The Five Essential Questions
• What influences stream flow?
• How do human activities influence stream health?
• How does energy and nutrients flow in a stream?
• What habitats are found in the stream?
• What is connectivity within a watershed?

Study II: A study of Ohio farmers
• Project funded by the Climate, Water, Carbon
Initiative at OSU
• Interviewed 20 farmers about land use and
management decisions related to nutrient
management– Probed knowledge about the nutrient cycle, impacts, and
mitigation actions
– Probed perceptions of risk and influences on decision making

Influences on Farmer Decision Making
• Younger, more environmentally concerned farmers
demonstrate higher knowledge scores
– Younger = Greater concern?
– Greater concern = Greater knowledge?
• Financial and environmental perceptions of risk
related to nutrient loss were equal
• 83% of farmers responded that something other than
profit (stewardship, lifestyle) was their primary goal
![Page 16: Robyn S. Wilson, PhD School of Environment and Natural Resources Environmental Social Sciences Lab The Ohio State University Climate Change and Water Quality](https://reader035.vdocuments.us/reader035/viewer/2022081520/56649e4a5503460f94b3ecd6/html5/thumbnails/16.jpg)
Summary
• Citizen knowledge about what makes a healthy stream
and human impacts on the stream is low
– Desire to take action to protect water quality depends on
awareness of the problem, perception of risk, and perceived
ability to take action
• Farmer knowledge about nutrient cycle fairly high – but
not reflecting current phosphorus issues
– Desire to take action to protect soil and water quality depends on
both financial and environmental perceptions of risk
![Page 17: Robyn S. Wilson, PhD School of Environment and Natural Resources Environmental Social Sciences Lab The Ohio State University Climate Change and Water Quality](https://reader035.vdocuments.us/reader035/viewer/2022081520/56649e4a5503460f94b3ecd6/html5/thumbnails/17.jpg)
Conclusions
• Enhancing knowledge is important…but communication
must also address individual differences in motivation,
values, perceived risk, etc.
• Improving water quality requires addressing decision
making from the top down and bottom up
• Climate change just another challenge for water quality
– Potential for behavioral change to counteract any predicted
negative impacts on water quality?
