Maumee Basin Lake Erie HABS Nutrient Management Options Comparative Analysis

Comparing the options for reducing nutrient runoff

Principal Investigator

Timothy Haab, Ohio State University


New research at Ohio State researcher helps land and water managers gauge the nutrient impacts of potential actions.

There is more than one way to reduce the amount of nutrients that get into Lake Erie from agricultural lands. To help decision makers and stakeholders address the issue, an Ohio State researcher is developing a comparative analysis for the Maumee Basin.

Timothy Haab, professor and department chair for Ohio State’s Department of Agricultural, Environmental, and Development Economics, will create a grid of management options and metrics. “We need to understand what we know and what we don’t know about current nutrient reduction efforts and possible solutions,” Haab said.

His analysis will include the relative strengths, weaknesses, pros, cons, costs, and benefits of possible solutions. Each proposed solution will be measured against a specified target such as a given reduction in a nutrient overage. The management options will likely include the status quo, incentive-based solutions, voluntary and engineering solutions and direct controls on nutrient use.  Haab will look at traditional cost and benefit measures as well as indicators of social acceptability and/or political feasibility. He will use existing data to fill in cells and identify critical gaps in data.

The End Result

A new tool to help decisionmakers weigh the water quality impacts of their options.
