| A mixed-integer programming model is developed to assess the economic feasibility of siting a woody biomass-based ethanol facility in the central Appalachian hardwood region. The model maximizes the net present value (NPV) of a facility over its economic life. Model inputs include biomass availability, biomass handling system type, plant investment and capacity, transportation logistics, feedstock and product pricing, project financing, and taxes. Four alternative woody biomass handling systems, which include all processes from stand to plant, are considered. Eleven possible plant locations were identified based on site selection requirements. Results showed that the optimal plant location was in Buckhannon, West Virginia. The NPV of the plant with a... |

| This paper provides an economic analysis that compares the profitability and land management capability of four different organic cropping systems used to produce winter squash (Cucurbita pepo cv. ‘Delicata’) and cabbage (Brassica oleracea var. capitata cv.’ Farao’). The organic cropping systems are part of a long term experiment designed for vegetable production in the Northeast, and designed to maintain ecological integrity and contribute to environmental stewardship. Our research addresses the causal chain from soil processes to economic outcomes including soil quality, efficiency in cycling of nutrients, off-farm impacts, pressures from weeds, insects and diseases, crop yield and quality, and marketing opportunities. Interactive crop budgets were... |

| On a topic like the environment, communication among scholars from different disciplines in the natural and social sciences is both important and difficult, but such communication has been far from perfect. Economists themselves may have contributed to some rather fundamental misunderstandings about how economists think about the environment, perhaps through our enthusiasm for market solutions, perhaps by neglecting to make explicit all of the necessary qualifications, and perhaps simply by the use of jargon that has specific meaning only to other economists. In this brief essay, we seek to clarify some of these misunderstandings and thus to improve future interdisciplinary communication. We hope that natural scientists and other non-economists will take... |

| The contents of this staff paper are based on the analysis of the Sodsaver provision prepared for the South Dakota Corn Utilization Council and the South Dakota Department of Agriculture. In addition this paper contains a summary of the policy discussion in January 2009 prior to South Dakota’s decision to not participate in the “Sodsaver” provision. Finally, a copy of the professional poster formatted for this publication is shown in Appendix 1. |

| An economic evaluation of wet corn gluten feed used in beef feedlot finishing was done. Data were from feeding trials at North Dakota State University. Four rations were analyzed at 0 percent, 28 percent, 56 percent, and 85 percent wet corn gluten based on dry matter intake. Data were entered into a computer model that integrated the feeding trial data with economic input and output prices. A typical feedlot example was used. Results indicated that the 56 percent ration was the most biologically efficient. A matrix of results can be shown for various corn prices, relative to wet corn gluten feed prices and quantities fed. Based on this study, wet corn gluten feed is priced competitively with other feed stuffs. |

| The perceived value of integrating small partial- equilibrium structural models of individual livestock industries into a comprehensive single-sector model is to take advantage of the interrelationships that are usually expressed by cross elasticities on both the supply and demand sides of these industries. Model integration should provide a more realistic representation of the livestock industries and an improved mechanism for industry analyses. However, model integration could also lead to increased error in model simulation that could reduce the value of the larger model for those purposes. Using forecasting as an example application, this paper investigates how the increased endogenisation of cross-commodity relationships in alternative structural... |

| Farming communities in water-scarce regions increasingly practice the use of urban wastewater in agriculture. Untreated urban wastewater is generally considered unacceptable for direct use because of potential health risks. However, in many parts of the world, poor farmers in peri-urban areas use untreated wastewater. This situation is considered likely to continue even in the foreseeable future due to the high investment cost associated with the installation of treatment facilities. |

| The present study has been carried out in the Barabanki district of Uttar Pradesh on economic analysis of menthol mint cultivation in the year 2010. The economics has been worked out by comparing costs and returns at different stages by the conventional method. The linear production function has been fitted to evaluate the resources-use efficiency in the production of menthol mint. The study has shown that the major portion of operational cost is shared by hired labour, interculture operations, distillation charges, irrigation and machine / tractor charge. The overall benefit-cost ratio has been found to be 2.55, which indicates a higher profit for farmers on less investment in mint cultivation. The independent variables like human labour, machinery,... |
