Abstract: | Shelterbelts have been shown to mitigate livestock odors incrementally through complex physical and social dynamics. By surveying
Iowa hog producers, we assessed the current degree of shelterbelt usage by pork producers, examined producers’ beliefs and
concerns regarding shelterbelt usage for odor mitigation and estimated both their willingness to pay and their overall demand
for shelterbelts. Overall, Iowa hog producers display strong beliefs that shelterbelts help, social-psychologically, to mitigate
odors and generally believe that shelterbelts physically reduce odors. Seventy-five percent of producers expressed a mean
willingness to pay $0.18 per pig produced annually. Sixty percent are willing to pay within a range of estimated costs, and
13% are willing to pay more. Overall, younger (<mean) producers are the most probable users of this technology, and they tend
to meet four criteria: they plan to be at the same site for over 10 years; they are located in regions with high pig populations;
they are at higher risk of affecting neighbors with odors, due to their proximity; they appreciate the more intangible perceived
benefits of using shelterbelts (e.g., those associated with social-psychological responses). Overall, the younger producers
perceived excessive cost/labor requirements as their main concerns. This information is critical to guide future extension
programming that addresses all key concerns of current and potential users of shelterbelts. |
