| 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 analysis estimates the profitability of restoring wetlands for the sale of carbon offsets. Results indicate that about 7% to 12% of the recently restored grassed wetlands of the prairie pothole and high plains regions and 20% to 35% of the forested wetlands of the Mississippi alluvial valley and Gulf-Atlantic coastal flats regions could have carbon offset values that exceed the cost of restoring the wetland and the opportunity cost of moving the land out of agricultural production. Given the uncertainties, the analysis applies conservative estimates of wetlands’ costs, offset prices, and wetlands’ effects on greenhouse gases. |

| 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... |

| Nitrogen is an important agricultural input that is critical for crop production. However, the introduction of large amounts of nitrogen into the environment has a number of undesirable impacts on water, terrestrial, and atmospheric resources. This report explores the use of nitrogen in U.S. agriculture and assesses changes in nutrient management by farmers that may improve nitrogen use effi ciency. It also reviews a number of policy approaches for improving nitrogen management and identifi es issues affecting their potential performance. Findings reveal that about two-thirds of U.S. cropland is not meeting three criteria for good nitrogen management. Several policy approaches, including fi nancial incentives, nitrogen management as a condition of farm... |

| Pheasant hunting benefits of the Conservation Reserve Program (CRP) were approximately $80 million/year in 1991 in states where the CRP appears most critical to pheasant populations. To obtain this benefit measure, tire demand for pheasant hunting was estimated using a recently developed multi-site demand model, a national survey on recreation, and environmental data processed through a geographic information system (GIS). Thus not only is the resulting evaluation of the CRP'S environmental impacts more accurately assessed than through the use of the generalized, supply-demand equilibrium models of previous work, but, more importantly, the environmental benefits of program acreage can he compared across field locations allowing subtle changes in policy to... |

| The objective of this analysis is to describe and, if possible, measure gains that farmland owners may have seen because of the public's demand for wetland services. To do so, we first consider landowners' ability to directly sell onsite (hunting, fishing, wildlife viewing) and offsite (water quality, groundwater recharge, etc.) wetland services. We found little evidence that landowners sell wetland services. We then consider farmland owners' gains from the mitigation banking system. We found that, with less than 200 approved mitigation banks on farmland, farmland owners had some but limited opportunities to participate in mitigation markets. Finally, we consider landowners' gains from the sale of wetland easements through the USDA's Wetland Reserve... |

| 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... |

| 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. |

| 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... |

| This paper presents the methodology, assumptions, and data used to generate regional and national environmental benefit estimates of the USDA’s Conservation Reserve Program (CRP). It’s assumed that, without the program, production and conservation practices on CRP lands would be the same as those used on surrounding lands. When range and forest lands are (are not) included as land-use options, 54 (71) percent of the CRP land would be in crop production—which is consistent with past analyses. Soil erosion would be 222 to 248 million tons per year—about 11 percent—higher than the current level. Benefits are estimated by applying environmental benefit models, estimated in previous analyses, to the CRP’s estimated effect on erosion and wildlife habitat.... |
