| The objective of this research is to value soil conservation's impact on reservoirs. Using a model based on replacement cost, we estimate the benefits gained by marginal decreases in soil erosion for more than 75,000 reservoirs across the contiguous States. We aggregate benefits across the reservoirs within each of the 2,111 U.S watersheds in order to produce regional benefit estimates. Results show that a one-ton reduction in soil erosion provides benefits ranging from zero to $1.67. Our estimated model can be used to assess conservation benefits. For example, the lower level of soil erosion in 1997, relative to the 1982 level, preserved $139 million in reservoir benefits. |

| This report estimates the impact that high levels of enrollment in the Conservation Reserve Program (CRP) have had on economic trends in rural counties since the program's inception in 1985 until today. The results of a growth model and quasi-experimental control group analysis indicate no discernible impact by the CRP on aggregate county population trends. Aggregate employment growth may have slowed in some high-CRP counties, but only temporarily. High levels of CRP enrollment appear to have affected farm-related businesses over the long run, but growth in the number of other nonfarm businesses moderated CRP's impact on total employment. If CRP contracts had ended in 2001, simulation models suggest that roughly 51 percent of CRP land would have returned... |

| U.S. farmers and ranchers produce a wide variety of commodities for food, fuel, and fiber in response to market signals. Farms also contain significant amounts of natural resources that can provide a host of environmental services, including cleaner air and water, flood control, and improved wildlife habitat. Environmental services are often valued by society, but because they are a public good—that is, people can obtain them without paying for them—farmers and ranchers may not benefit financially from producing them. As a result, farmers and ranchers under-provide these services. This report explores the use of market mechanisms, such as emissions trading and eco-labels, to increase private investment in environmental stewardship. Such investments could... |

| We investigate what farmland preservation programs reveal about the importance of protecting different rural amenities. An extensive content analysis of the enabling legislation of various farmland protection programs suggests wide variation exists in the protection of amenities. An analysis of 27 individual Purchase of Development Rights (PDR) programs' selection criteria suggests these programs favor preserving amenities that are jointly provided by cropland and livestock operations. These PDR selection criteria also reveal unique preferences regarding the spatial patterns of preserved agricultural lands. Variation in relative weights given to protecting most parcel characteristics in PDR programs is not easily explained by factors that characterize... |

| Agri-environmental policy is at a crossroads. Over the past 20 years, a wide range of policies addressing the environmental implications of agricultural production have been implemented at the Federal level. Those policies have played an important role in reducing soil erosion, protecting and restoring wetlands, and creating wildlife habitat. However, emerging agri-environmental issues, evolution of farm income support policies, and limits imposed by trade agreements may point toward a rethinking of agri-environmental policy. This report identifies the types of policy tools available and the design features that have improved the effectiveness of current programs. It provides an indepth analysis of one policy tool that may be an important component of a... |

| Application of the tobit model to estimate economic welfare is transferred from the consumer side to the producer side. Supply functions are estimated for multioutput irrigators in the Pacific Northwest. Empirical procedures are then developed for computing expected producer's surplus from the output supply functions. Confidence intervals for the surplus measures are generated using the Krinsky-Robb method. An experiment predicts decreases in surplus given increases in water pumping cost. The experiment replicates possible increases in hydroelectric prices due to the salmon recovery program in the Columbia-Snake River Basin. Output substitution explains producers' ability to mitigate the effect of the price increases on producer's surplus. |

| How might increases in commodity prices, along with the acreage reduction mandated in the 2008 Farm Act, impact the Conservation Reserve Program (CRP)? Modeling Strategy The Likely To Bid (LTB) model “restarts” the CRP from scratch. Uses National Resources Inventory data to find parcels “likely” to offer acreage to the CRP Policy scenarios We consider several scenarios, both with and without increases in CRP rental rates. Continuation of current prices, which are well above prices prevalent when most CRP contracts were enrolled Predicted prices due to an increase in biofuels production to 15 billion gallons Expectation that summer 2008 prices will be the norm Findings Continuation of current, relatively high commodity prices would have noticeable... |

| Nitrates in drinking water, which may come from nitrogen fertilizers applied to crops, are a potential health risk. This report evaluates the potential benefits of reducing human exposure to nitrates in the drinking water supply. In a survey, respondents were asked a series of questions about their willingness to pay for a hypothetical water filter, which would reduce their risk of nitrate exposure. If nitrates in the respondent's drinking water were to exceed the EPA minimum safety standard, they would be willing to pay $45 to $60, per household, per month, to reduce nitrates in their drinking water to the minimum safety standard. There are 2.9 million households in the four regions studied (White River area of Indiana, Central Nebraska, Lower... |

| Public amenities provided by a rural agricultural landscape, arising from open space and farm activity, are important to many citizens and policymakers. Widespread development of farmland in some parts of the country has spawned an expanding array of farmland protection programs by county, State, and Federal governments, as well as by nonprofit organizations. To investigate the relative importance of preserving different amenities, this report examines the enabling legislation of these programs across the 48 contiguous States, and the implementation of these programs in five Northeastern States (Maryland, Massachusetts, New Jersey, Pennsylvania, and Vermont). The report also assesses how farmland protection programs fit into the broader array of rural land... |

| The range of environmental problems confronting agriculture has expanded in recent years. As the largest program designed to mitigate the negative environmental effects of agriculture, the Conservation Reserve Program (CRP) has broadened its initial focus on reductions in soil erosion to consider other landscape factors that may also be beneficial. For example, preserving habitats can help protect wildlife, thus leading to more nature-viewing opportunities. This report demonstrates how nonmarket valuation models can be used in targeting conservation programs such as the CRP. |

| Federal programs may encourage farmers to convert native grasslands—land that has never been cultivated — to production of corn, soybeans, and other crops, leading to potential losses of Northern Plains' native grasslands. Federally subsidized crop insurance reduces risk associated with crops grown on converted grasslands and, over time, increases average returns to production by making crop farming more attractive. Other programs, including Federal disaster assistance and marketing loan benefits, also reduce risk and increase returns to crop production on converted grasslands. While these programs can be important risk management tools for farmers, they may also result in unintended, environmentally damaging actions. |

| Many conservation programs, such as the Conservation Reserve Program (CRP), use indices to select offers. When modeling how changes in the index weights effect program outcomes, one must account for the attributes of available land, and which landowners chose to participate. This paper introduces a methodology to account for changes in participation as index weights change. Data on the actual CRP (all offers received) are combined with an artificial population of available lands (based on National Resources Inventory data). Bootstrapping methods are used to calibrate estimates of participation probability, and to account for errors-in-variables when estimating how index scores effect this probability. Preliminary analysis suggests that accounting... |
