Buffer Strips on Hartcliffe County Creeks: A Debate Kit

Resolution: "Hartcliffe County should require every farm to keep a planted buffer strip along any creek that crosses its land, even though the strip takes cropland out of production."

Background: Hartcliffe County is a fictional area of grain and vegetable farms crossed by small creeks that flow into a shared river downstream. Farmers spread fertilizer to grow their crops, but rain can wash some of that fertilizer, rich in nitrogen and phosphorus, off the fields and into the creeks. Those same nutrients that help crops grow also feed algae in the water. When large amounts of algae grow and then die, bacteria use up the oxygen in the water as they break the algae down. Most fish need dissolved oxygen above 5 mg/L, so a drop in oxygen can kill fish and harm the creek.

A buffer strip is a band of grass, shrubs, or trees left unplanted with crops along the water's edge. It slows runoff and lets the soil and roots trap nutrients before they reach the creek. Requiring buffer strips would protect the water, but it would also take a band of productive land out of use on every farm along a creek.

Roles: The affirmative team argues for the requirement, the negative team argues against it, and three student judges score both teams with the rubric and ask one question each. Each team should prepare an opening claim, two supporting points with evidence, and at least one rebuttal.

Case for requiring buffer strips:

1. Fertilizer runoff feeds algae; when the algae die, the water loses oxygen, and most fish need dissolved oxygen above 5 mg/L, so runoff can cause fish kills downstream. (Source: standard water-quality benchmark, EPA and USGS.)
2. Buffer strips are a well-established, low-technology method: a band of grass and roots along the water traps nutrients and slows runoff before it reaches the creek. (Source: standard soil-conservation practice.)
3. A fictional Hartcliffe drinking-water manager testifies that when creek nutrient levels rise, the downstream utility must spend more to remove nitrate before delivering water, a cost paid by everyone on the system. (Illustrative testimony created for this debate.)
4. The creeks and the river they feed are a shared resource used by many people downstream, so protecting them is not only each farm's private choice.

Case against requiring buffer strips:

1. Fertilizer is not only a pollutant; it is a necessary resource that feeds the food supply. Every acre planted in a buffer strip is an acre that grows no crop, and farms run on thin margins, so removing a strip of cropland cuts real income.
2. A single required width treats every farm the same, but a steep field beside a creek and a flat field farther away pose very different runoff risks, so a fixed rule may force some farms to give up land for little gain.
3. A fictional Hartcliffe farm cooperative argues that voluntary programs with cost-sharing already lower runoff while keeping farmers willing to cooperate, and that a mandate would breed resistance and lawsuits instead of cleaner water. (Illustrative testimony created for this debate.)
4. Taking cropland out of production across many farms could lower local harvests and raise food prices, a cost that also falls on the public the rule is meant to help.
