| Agricultural nitrogen losses are the major contributor to nitrogen loads in the Mississippi River, and consequently, to the existence of a hypoxic, or dead, zone in the Gulf of Mexico. Focusing on two small agricultural watersheds in southeast Minnesota, simulation results from the Agricultural Drainage And Pesticide Management (ADAPT) model were combined with a linear-optimization model to evaluate the environmental and economic impact of alternative land-use policies for reducing nitrogen losses. Of particular importance was the studys explicit focus on agricultural subsurface (tile) drainage, which has been identified as the major pathway for agricultural nitrogen losses in the upper Midwest, and the use of drainage-focused abatement policies.... |

| Increases in the United States tariff-rate quota for sugar are simulated to determine the impact of Cuban market access and an increased Mexican allotment. The effects on both domestic and international sugar markets, including production, consumption, prices and trade, are determined and welfare effects identified. This analysis is carried out using a partial-equilibrium simplified world trade model, Modele International Simplifie de Simulation (MISS), which simulates, in a comparative-static framework, the effects of various policy actions. |

| In the wake of Hurricane Katrina, the Louisiana Coastal Protection and Restoration Authority (CPRA) was established to integrate programs for habitat restoration and infrastructure protection. The Authority has begun aligning the state’s coastal spending to reflect increasing public interest in the restoration of surface acreage. Concurrent with these changes, programmatic emphasis has been placed on rapid land building (RLB) techniques that rely on mechanical dredges and sediment conveyance pipelines to build new land. The apparent costs and benefits of this approach are increasingly compared in the scientific community to more traditional and natural methods of restoration, such as freshwater diversions (DIV). Given limited state and federal budgets for... |

| Forest residues are being considered as potential feedstock for a biomass-to-ethanol facility in Minnesota (USA), using residues from major wood-producing counties in Minnesota, Wisconsin, and Michigan. Results indicate that marginal residue costs delivered to a conversion facility would be $56-80/Mg for a small (95-189 MM liters) plant, and about $81/Mg for a larger (379 MM liters) plant. Output beyond these levels would involve substitution of lower-cost market pulpwood as the plant feedstock because of relatively high marginal residue costs. Sensitivity analysis indicates that either a 20-percent increase or decrease in the quantity of available residue would impact marginal cost estimates by no more than $15/Mg. |

| Corn stover harvest and transport cost functions were estimated for two harvest operations for a proposed biomass-to-ethanol conversion facility located in southern Minnesota, USA. This work presents an alternative methodology to estimating corn stover quantities and harvest costs at the county level, taking into account county-specific yields, transportation distances, erosion constraints, machinery specifications, and other key variables. Monte Carlo simulation was also used to estimate the probability distribution of costs under alternative assumption on key parameters whose values vary widely in the literature. Marginal stover cost for 50MM gal/year of ethanol output was estimated at $54/dt ($0.77/gal ethanol) for the more intensive harvest method... |

| Research was undertaken to determine the economic feasibility and environmental impact of harvesting corn stover and hardwood forest residue in Minnesota and surrounding states for conversion to fuel ethanol at facilities located in Minnesota. It was estimated that only 7 of the total 41 million dry tons of corn stover produced and 3 of the 6.5 million dry tons of hardwood residue produced in the study region would likely be harvested each year. From these quantities, it would be physically feasible to produce about 874 million gallons of ethanol annually. It was estimated that 200 million gallons could be harvested at a delivered feedstock cost below $40 per ton. Results indicate further that ethanol derived from corn stover would be cost competitive... |

| Agricultural nitrogen is a major contributor to Gulf of Mexico hypoxia, and research has shown that agricultural subsurface tile drainage is a major carrier of nitrogen from croplands to streams and rivers. This study compares the results of abating nitrogen under a retired-land minimization policy with those of a new revenue-maximizing policy, paying particular attention to the role of tile-drained land. Findings reveal the retirement-minimizing policy resulted in more tile-drained land being retired and less being fertilizer-managed than was optimal under the net-return maximizing policy. Also, it led to a greater economic burden being shouldered by tile-drained land. Under both cases, tile drainage dominated the abatement process. |

| In this study, we investigate the link between hurricane characteristics, demographics of the Coastal Gulf of Mexico residents, including their household location, and their respective evacuation behavior. Our study is significantly different from the previously made studies on hurricane evacuation behavior in two ways. At first, the research data is collected through recording responses to a series of hypothetical situations which are quite identical to the set of information that people are used to see during the hurricane season. Secondly, this study addresses and includes response heterogeneity while analyzing sample behavior, an issue which has not been addressed in previous research on hurricane evacuation behavior in spite of its importance. |

| The objective of this research is to identify factors that influence both the decision (yes or no) and level of flood insurance among coastal homeowners in the southeast U.S. Recently flood damage has dramatically increased (Flood), and Crossett et al. (2004) report that coastal populations are growing. And in spite of rising costs of living in coastal areas, people are willing to pay more for access to ocean views and other natural amenities associated with coastal living (Bin and Kruse, 2006). Although the federal government provides flood insurance programs and encourages at-risk residents to insure their property from flood, rates of uptake remain low (Burby, 2001; Kunreuther, 2006; Landry and Jahan-Parvar, 2009). The National Flood Insurance... |

| It was the objective of this study to take a first cut at understanding the cost structure of coastal restoration technologies and to obtain some preliminary measures of cost-effectiveness of these technologies. This analysis focused on restoration projects funded by the Coastal Wetlands Planning, Protection, and Restoration Act (CWPPRA, also known as the Breaux Act), the primary funding source for restoration projects in Louisiana. Projects chosen were those that included a component of dredging sediment with the explicit objective of increasing acreage in the project area, i.e., of building land. |

| The Cottonwood River Watershed is located in southwestern Minnesota, draining 1,310 square miles of land within the Minnesota River Basin. The watershed is comprised of parts of Brown, Cottonwood, Lyon, Murray, and Redwood Counties. This essay gives a brief account of the initial European settlement of the area and the establishment of the current political boundaries. It then focuses on the major developments in agricultural production during the past 150 years, touching on the changes in landscape and wildlife due to drainage and restructuring of water bodies and the clearing of forest land. |
