| The profitability of planting flood tolerant crops in flood plains relative to traditional row crops is evaluated under different assumptions concerning flood frequency and the level of government crop subsidy. The alternative crops evaluated are short rotation woody crops and herbaceous energy crops. The analysis is conducted for two growing environments: Louisa County, Iowa and Saline County. Missouri. The economic indicator used to value the alternative scenarios is annualized net return per acre. This indicator can account for the significant time lags between planting and harvesting of the two alternative crops. The results indicate that row crops dominate the flood tolerant crops until flood frequency approaches 50 percent. The positive... |

| Restricting or eliminating the use of atrazine in the Midwest would have important economic consequences for farmers and consumers. Atrazine is an important herbicide in the production of corn and other crops in the United States. Since atrazine is such an important herbicide, mandatory changes in application strategies are likely to generate sizable costs for producers and consumers. However, recent findings indicate that elevated amounts of atrazine are running off fields and entering surface water resources. This report presents the costs and benefits of an atrazine ban, a ban on pre-plant and pre-emergent applications, and a targeted ban to achieve a surface water standard. A complete atrazine ban is hypothesized to be the costliest strategy, while the... |

| The interface between RS-CRAM and the environmental component of the integrated modeling system is described for crops, crop sequences, and management systems representative of western Canada. An experimentally designed set of EPIC simulations were performed to generate erosion output that was used to construct wind and water erosion metamodels (response functions). The results of the EPIC simulations indicate that wind and water erosion would be the dominant erosion problem over most of Saskatchewan and Manitoba. For Alberta, water erosion was predicted to be the dominant problem, except for the southern portion of the province. Erosion impacts were sensitive to tillage and cropping patterns. EPIC-predicted yields did not vary much across tillage, a... |

| This report describes an integrated agro-ecological modeling system that was developed to assess the potential economic and soil erosion impacts of different agricultural policies for the Canadian prairie provinces of Alberta, Saskatchewan, and Manitoba. The system was constructed by linking erosion metamodels (response functions), based on multiple simulations of the USDA Erosion Productivity Impact Calculator (EPIIC), with a modified version of Agriculture Canada's Canadian Regional Agriculture Model (CRAM) denoted as RS-CRAM (resource sensitive CRAM). A summary of both the environmental and agricultural decision (RS-CRAM) components are presented, including a description of the modifications and enhancements that were made to CRAM. Results of policy... |
