Willingness To Pay For Clear Lake Cleanup, Christopher D. Azevedo, Joseph A. Herriges Sr., Catherine L. Kling

Catherine Kling

The water quality in Iowa’s lakes has been a hot topic lately. Concerns about the water quality in many of the state’s lakes have brought increased attention to the value of the lakes as a recreational resource. One lake that has experienced recent water quality problems, as well as the accompanying publicity, is Clear Lake, located in Cerro Gordo County.

As increased attention is focused on the issue of water quality in the state of Iowa, policymakers must grapple with the pressures of balancing federal water quality requirements, tight conservation budgets, and citizen concern for environmental preservation and restoration of Iowa’s water resources. Efforts to improve water quality typically entail significant costs, either in the form of state resources to fund cleanup efforts or private costs associated with altering land uses, farming practices, municipal treatment facility expansions, or other investments.

On October 12–13, a workshop funded by the National Science Foundation was held at Iowa State University in Ames, Iowa with a goal of identifying research needs related to coupled economic and biophysical models within the FEW system. Approximately 80 people attended the workshop with about half representing the social sciences (primarily economics) and the rest from the physical and natural sciences. The focus and attendees were chosen so that findings would be particularly relevant to SBE research needs while taking into account the critical connectivity needed between social sciences and other disciplines. We have identified several major gaps ...


The Optimality Of Using Marginal Land For Bioenergy Crops: Tradeoffs Between Food, Fuel, And Environmental Services, Adriana M. Valcu-Lisman, Catherine L. Kling, Philip W. Gassman 2017 Iowa State University

The Optimality Of Using Marginal Land For Bioenergy Crops: Tradeoffs Between Food, Fuel, And Environmental Services, Adriana M. Valcu-Lisman, Catherine L. Kling, Philip W. Gassman

Catherine Kling

We assess empirically how agricultural lands should be used to produce the highest valued outputs, which include food, energy, and environmental goods and services. We explore efficiency tradeoffs associated with allocating land between food and bioenergy and use a set of market prices and nonmarket environmental values to value the outputs produced by those crops. We also examine the degree to which using marginal land for energy crops is an approximately optimal rule. Our empirical results for an agricultural watershed in Iowa show that planting energy crops on marginal land is not likely to yield the highest valued output.

Nonpoint source pollution from agriculture is the main source of nitrogen and phosphorus in the stream systems of the Corn Belt region in the Midwestern US. The eastern part of this region is comprised of the Ohio-Tennessee River Basin (OTRB), which is considered a key contributing area for water pollution and the Northern Gulf of Mexico hypoxic zone. A point of crucial importance in this basin is therefore how intensive corn-based cropping systems for food and fuel production can be sustainable and coexist with a healthy water environment, not only under existing climate but also under climate change conditions in ...

In early August 2014, the municipality of Toledo, OH (USA) issued a ‘do not drink’ advisory on their water supply directly affecting over 400,000 residential customers and hundreds of businesses (Wilson, 2014). This order was attributable to levels of microcystin, a potent liver toxin, which rose to 2.5 mg L1 in finished drinking water. The Toledo crisis afforded an opportunity to bring together scientists from around the world to share ideas regarding factors that contribute to bloom formation and toxigenicity, bloom and toxin detection as well as prevention and remediation of bloom events. These discussions took place at ...


Degraded Water Quality In Lakes: Consequences For Use, Hocheol Jeon, Catherine L. Kling, Yongjie Ji 2017 Iowa State University

Degraded Water Quality In Lakes: Consequences For Use, Hocheol Jeon, Catherine L. Kling, Yongjie Ji

Catherine Kling

Iowa, like many states in the Midwest, suffers from poor water quality. Excess nutrients in the state’s lakes and streams contribute to odor, limited clarity, excess algae and plant growth, and can contribute to a number of other undesirable changes to habitat and water quality. These changes, in turn, can reduce the usage and enjoyment of lakes and streams. Likewise, improvements in water quality brought about by reduced nutrient pollution or lake improvement projects can increase the number of visitors and their enjoyment of natural environments. To better understand what Iowans value about their natural environment and how changes ...


Economic Valuation Of Ecosystem Benefits From Conservation Practices Targeted In Iowa Nutrient Reduction Strategy 2013: A Non Market Valuation Approach, Mainul Hoque, Catherine L. Kling 2017 Iowa State University

Economic Valuation Of Ecosystem Benefits From Conservation Practices Targeted In Iowa Nutrient Reduction Strategy 2013: A Non Market Valuation Approach, Mainul Hoque, Catherine L. Kling

Catherine Kling

With the aim of improving water quality, the Iowa Nutrient Reduction Strategy 2014 sets a goal of reducing agricultural non-point-source generated nitrogen load by 41 percent and phosphorus load by 29 percent in Iowa’s waterways. The “strategy” describes several land use that could achieve those reductions, such as widespread adoption of conservation practices in farming, land retirement, and wetland restoration that can meet the specified target reduction. The goal of the current study is to identify the range of ecosystem benefits resulting from the conservation practices associated with each of these scenarios and apply a nonmarket valuation method to ...

Key Differences Between Lakes And Reservoirs Modify Climate Signals: A Case For A New Conceptual Model, Nicole M. Hayes, Bridget R. Deemer, Jessica R. Corman, N. Roxanna Razavi, Kristin E. Strock

Faculty and Staff Publications By Year

Lakes and reservoirs are recognized as important sentinels of climate change, integrating catchment and atmospheric climate change drivers. Climate change conceptual models generally consider lakes and reservoirs together despite the possibility that these systems respond differently to climate-related drivers. Here, we synthesize differences between lake and reservoir characteristics that are likely important for predicting waterbody response to climate change. To better articulate these differences, we revised the energy mass flux framework, a conceptual model for the effects of climate change on lentic ecosystems, to explicitly consider the differential responses of lake versus reservoir ecosystems. The model predicts that catchment and ...

Fecal Indicator Bacteria (FIB) such as Escherichia coli (E. coli) are a leading cause of surface water impairments in the United States. However, the relative impacts of different watershed characteristics on microbial water quality in agriculturally dominated watersheds are unclear. Spatial and statistical analyses were utilized to examine relationships between watershed characteristics and FIB and a multiple regression model was created. Geometric mean E. coli concentration data were obtained for 395 ambient water quality monitoring locations in Iowa. Watersheds were delineated for thirty randomly selected monitoring locations and drainage areas ranged from 93 to 1.1 million hectares. Watershed characteristics ...
