| A new, post-industrial, paradigm for agriculture is emerging under the concept of sustainable agriculture. The sustainability paradigm has emerged to solve problems created by the industrial model, primarily environmental pollution and resource base degradation. The role of farm size in this transformation to a more sustainable agriculture is the issue addressed. Using a descriptive approach, and relying on a survey of the literature including emerging paradigms and observations, we conclude that, from a sustainability perspective, the smallest effective size will be the most competitive size for farms, as for other knowledge-based enterprises of the future. |

| Contract grazing is compared with retained ownership of cattle using two frameworks-decision theory and portfolio analysis. The study area is West Virginia. Contracting is optimal under a wide range of price and weather scenarios and decision criteria. It also dominates other alternatives based on labor efficiency measures. The optimal portfolio consists of contract grazing and pasture rental, with the results insensitive to small changes in contract grazing returns. The decision theory and portfolio analyses are complementary; together, the two sets of results provide a comprehensive view of the optimal production alternative. Because different agents employ different decision criteria, this approach can increase the utility of results to decision... |

| Obesity constitutes an important public policy issue since it causes external costs to society through increased healthcare costs borne by taxpayers. This study employed random and fixed effects estimations and spatial autoregressive approaches under a panel data structure to unravel possible socioeconomic and built environment factors contributing to obesity. Though there is no statistical evidence for time invariant fixed effects, empirical evidence shows that obesity is a spatially non-random event. Educational attainment that raises both human and social capital as well as changes in the built environment could play a vital role in controlling obesity. |

| The extent to which individual factors influence the adoption of sustainable agricultural practices is estimated using a logit model and data from a 1990 survey of West Virginia producers. The results are, as expected, different than those for conventional agricultural technologies. For example, the effects of human capital characteristics are significant, while those for structural and institutional characteristics are not. However, the likelihood of adoption of sustainable agricultural practices is affected most by the environmental characteristic of whether or not the producer is aware that ground water contamination exists on his farm. This creates an important "awareness effect" upon which policies to promote sustainable agriculture adoption can... |

| Direct farm marketing sales in the Northeastern region of the U.S. and more specifically in the state of West Virginia increased during the 1990s. To understand the factors that influence recent trends in direct farm marketing, this analysis uses a regression function to test the relationships between county direct farm marketing sales and county spatial and socio-economic characteristics. Data from West Virginia is used to analyze the relationship between the consumer, land characteristics, and farm sales. The results reveal that the model is relatively accurate and multiple consumer characteristics and land use variables significantly influence sales of farm goods marketed directly to consumers. |

| To understand the factors that influence farm direct marketing, a linear regression model is estimated to test the relationships between county-level direct market sales and socioeconomic, agricultural production, and location characteristics for West Virginia. The results show that higher median housing value, increased population density, a younger population, a greater number of direct market farms, more diversity of fruit and vegetable production and closer proximity to Washington, D.C., increase direct market sales. The results have implications for other states with a large proportion of small and part-time farmers, many of whom are located in close proximity to metropolitan areas. |

| The Opequon watershed is located in northern Virginia (VA) and the eastern panhandle of West Virginia (WV). In both states, Opequon Creek is classified as impaired based on violations of bacteria, benthic and biologic standards. Both VA and WV are using Total Maximum Daily Load (TMDL) plans to improve water quality within Opequon Creek. However, these TMDL plans are at different stages with VA being completed and WV still in progress. As part of the TMDL process in VA, this research is based on a contingent valuation survey which was developed to measure the expected monetary benefits of TMDL implementation throughout the Opequon watershed. On the basis of log-likelihood tests of grouped tobit models to explain willingness-to-pay (WTP) for watershed... |

| A disaggregated econometric model of the agricultural sector at the state level is constructed. Using time series data on West Virginia agriculture and three-stage least squares in estimation, the model is employed to examine how various components of the state's agricultural sector adjust to changes in certain price and nonprice variables. Results reveal characteristics of the state's agricultural economy that are both unique and useful - characteristics that are usually masked in aggregate models but that have profound implications for modeling producer decision making and policy formulation. |

| We explore the transfer of poultry litter among watersheds incorporating both economic characteristics (litter demand and supply) and environmental characteristics (vulnerability to phosphorus runoff, a major pollutant). A combination of techniques was employed: the Lemunyon-Gilbert P-Index model to determine watershed environmental vulnerability, GIS for land use coverages, and a goal focusing model (incorporating Saaty's eigen-value approach for penalty weight estimation) to identify optimal litter shipments among watersheds. Both primary and secondary data were used. The results should be useful to producers and policy makers in the study area and in other areas where poultry production is linked to water quality, and contribute to a more sustainable... |

| The U.S. market for commoditized beef is a dynamic one that has, over the last 30 years, seen decreases in per capita consumption and an increased reliance on large, integrated feedlot facilities that focus on efficient weight gain and producing carcasses deemed desirable according the USDA quality grading system. Because of the problems inherent in the conventional production system and the existence of farm-to-retail price spreads that do not favor primary cow-calf producers, analyses of alternative beef production and marketing strategies that facilitate enhanced profitability and simultaneously address surging consumer demand for specialty food products are necessary. To that end, focus of the current study was on the market potential for grass-fed... |

| The investment potential of warm-season grasses is compared with that of cool-season grasses, with special emphasis on hill-land beef production. In addition to evaluating relative costs and returns for various grazing systems, a sensitivity analysis is conducted. The results are then illustrated for a representative hill-land farm in West Virginia, and both an optimal and a set of quasi-optimal solutions are generated within the linear programming framework. In general, warm-season grasses are found to be a superior investment alternative for hill-land beef producers. |

| Cow-calf operations are important enterprises for family farmers in Appalachia and provide significant opportunity for supplemental income. This analysis constitutes a thorough economic assessment of pasture-raised beef production, an alternative to traditional production that could benefit the region's producers in terms of profitability and mitigated risk. Stochastic budgeting was utilized for profitability and risk comparison between traditional and pasture-raised operations and accounted for seasonal variability in prices, pasture availability and animal performance. Pasture-raised systems, in relation to traditional ones, were shown to consistently yield higher returns over variable costs and were shown less likely to yield losses over total costs... |
