A mail survey was used to gather information from the main food buyer in random households in southeast Missouri to analyze consumer preferences for locally grown food. A majority of shoppers in the region were not aware of the state's AgriMissouri promotion program. Consumers defined locally grown not as a statewide concept but as a narrower regional concept that could cross state boundaries. Most important when purchasing produce were quality and freshness, and most consumers perceived local produce at farmers' markets to be of higher quality and lower price. Farm households were not significantly different from other households in the region and did not show a preference or willingness to pay a price premium for local food products. Food buyers who were members of an environmental group had higher education and income and were more likely to purchase organic food and more willing to pay a higher price for local produce. Households in which someone was raised on a farm, or had parents who were raised on a farm, had a preference for locally grown food and were willing to pay a price premium for it. Marketing local products should stress quality, freshness, and price competitiveness, and appeal to environmentalists and those with a favorable attitude towards family farms.

The role of rising atmospheric CO in modulating estuarine carbonate system dynamics remains poorly characterized, likely due to myriad processes driving the complex chemistry in these habitats. We reconstructed the full carbonate system of an estuarine seagrass habitat for a summer period of 2.5 months utilizing a combination of time-series observations and mechanistic modeling, and quantified the roles of aerobic metabolism, mixing, and gas exchange in the observed dynamics. The anthropogenic CO burden in the habitat was estimated for the years 1765-2100 to quantify changes in observed high-frequency carbonate chemistry dynamics. The addition of anthropogenic CO alters the thermodynamic buffer factors (e.g., the Revelle factor) of the carbonate system, decreasing the seagrass habitat's ability to buffer natural carbonate system fluctuations. As a result, the most harmful carbonate system indices for many estuarine organisms [minimum pH, minimum Ω, and maximum pCO] change up to 1.8×, 2.3×, and 1.5× more rapidly than the medians for each parameter, respectively. In this system, the relative benefits of the seagrass habitat in locally mitigating ocean acidification increase with the higher atmospheric CO levels predicted toward 2100. Presently, however, these mitigating effects are mixed due to intense diel cycling of CO driven by aerobic metabolism. This study provides estimates of how high-frequency pH, Ω, and pCO dynamics are altered by rising atmospheric CO in an estuarine habitat, and highlights nonlinear responses of coastal carbonate parameters to ocean acidification relevant for water quality management.

The food access/availability environment is an important determinant of health outcomes in metro and non-metro areas. Future research should focus on more refined specifications that capture variability across non-metro settings.

Farmers' markets presumably benefit local economies through enhanced retention of local dollars. Unlike other studies, the net impact of farmers' markets on the West Virginia economy is examined. Producer survey results are used in estimating annual direct sales ($1.725 million). Using an IMPLAN-based input-output model, gross impacts are 119 jobs (69 full-time equivalent jobs) and $2.389 million in output including $1.48 million in gross state product (GSP). When the effect of direct revenue losses are included (primarily for grocery stores), the impact is reduced to 82 jobs (43 full-time equivalent jobs), $1.075 million in output, and $0.653 million in GSP.
