| 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. |

| 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... |

| A visitor’s decision to use a particular recreational site is influenced by the individual’s taste as well as the characteristics of the site. For this reason, improved knowledge of the visitors’ interests and factors influencing their choices are vital for both planning and policy formulations in coastal development. This study examines visitor characteristics and desired site specific characteristics in order to determine the factors affecting use of the Louisiana coast for specific recreational purposes. We use a multinomial logit model and internet survey data to evaluate the factors affecting individuals’ decisions to visit coastal Louisiana for a specific use. Results suggest that the major variables affecting the choice of coastal recreational... |

| A USGS analysis of land change data from satellite imagery and field observation indicated that 217 square miles of Louisiana's coastal wetlands were converted to open water because of Hurricanes Katrina and Rita. Because of their physical location and marine-dependence, commercial and recreational fishing sectors in Louisiana received a disproportional economic impact from the hurricanes of 2005. Storm surge modeling was accomplished using the ADCIRC model with data generated by the National Weather Service on storm trajectory and storm magnitude and detailed data on coastal bathymetry and elevation. In our application of the ADCIRC model, a grid composed of 1 square-mile cells (and encompassing the entire coastal management zone) was used within a GIS... |

| A multinomial logit model was estimated and used to analyze the impact of various producer characteristics on the adoption of flow-through and recirculating technology in soft-shelled crab production. Because of the industry's geographic isolation and high turnover rate, data was collected by personal interviews in 1991. The results suggest that increased adoption might be fostered by targeting education programs towards full time, family operated businesses in nontraditional production regions. However, development of effective education programs may be hindered by the lack of a significant relationship between producer adoption decisions and the information provided by university or extension personnel. |

| The income capitalization approach is used, based on expenditure and nonmarket values collected from travel-cost and contingent valuation methodologies, to measure the feasibility of running a self-sustaining recreational site in coastal Louisiana. Through Internet and intercept surveys, a total of 2,696 respondents, 88% of them anglers, provided information on economic expenditures, destination preferences, and preferences for specific site amenities regarding Elmer's Island. The purchase and subsequent opening of the area to the public were found to be self-sustaining even when considering conservative economic estimates. |

| The goal of this study was to produce a detailed aquaculture production model incorporating constraints unique to closed system culture and to conduct a formal economic analysis of closed system operation. Results generated by this model indicate that less than perfect management ability can eliminate the normal advantages associated with using high protein feed. While higher protein levels produce faster growth, and for this reason are often used in the industry, the increased direct feed costs and indirect costs due to metabolic feedbacks produce lower daily returns if high protein feed use continues through harvest. This model showed that inefficiency in solids removal negatively affects returns, but the majority of negative impacts were linked to... |
