Public support for integrated pest management (IPM) is derived in part from concerns over food safety and the environment, yet few studies have assessed the economic value of health and environmental benefits of IPM. An approach is suggested for such an assessment and applied to the Virginia peanut IPM program. Effects of IPM on environmental risks posed by pesticides are assessed and society's willingness to pay to reduce those risks is estimated. The annual environmental benefits of the peanut IPM program are estimated at $844,000. The estimates of pesticide risks and willingness to pay can be applied elsewhere in economic assessments of IPM.
Rose et al. 271exclusively on locally produced foods (i.e., a local food diet) for 4 weeks during the summer and fall of 2006. For this study, a local food was defined as a food produced within 100 miles of an individual's residence. Food records were used to assess each participant's compliance with the local food diet as well as the impact of following the diet on the intakes of energy, macronutrients, and fruits and vegetables. Body weight was assessed at baseline and immediately following the 4-week period. Compliance with the local food diet varied considerably, but the average intake of local foods increased from 15% of calories at baseline to 81% of calories during the local food diet. Compared to participants' baseline values, following the local food diet for 4 weeks significantly (p < 0.05) reduced reported intakes of energy and protein and increased reported intakes of dietary cholesterol, saturated fat, and servings of fruits and vegetables. Results from this pilot study suggest that individuals attempting to follow a local food diet vary in how they execute a local food diet and that following a local food diet may result in a reduction of energy intake. Future research into the impacts of following a local food diet on dietary quality is needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
