Última A Risk Analysis of Converting CRP Acres to a Wheat-Sorghum-Fallow Rotation 31 Williams, Jeffery R.; Llewelyn, Richard V.; Pendell, Dustin L.; Schlegel, Alan J.; Troy, Dumler. This study examines the economic potential of producing a wheat (Triticum aesitivum) and grain sorghum (Sorghum bicolor (L.) Moench) rotation with three different tillage strategies compared to the Conservation Reserve Program (CRP) in a semi-arid region. This research uses stochastic efficiency with respect to a function (SERF) to determine the preferred management strategies under various risk preferences and utility-weighted certainty equivalent risk premiums. Yields, input rates, and field operations from an experimental field in western Kansas are used to calculate net returns for each tillage strategy. Although current net returns to crop production using reduced tillage and no-tillage strategies are higher than CRP, risk analysis indicates CRP...

Ano: 2009 URL: http://purl.umn.edu/45985 Economic Considerations for Playa Management Alternatives 31 Jones, DeDe; Amosson, Stephen H.; Warminski, Patrick L.. Playa lakes are very important to the Texas High Plains. They provide habitat for a wide variety of wildlife, and are the Ogallala Aquifer’s primary recharge source. Plowing and sedimentation have caused substantial damage to the overall health of many playas. A need exists to protect this resource for future generations. Several government programs are available to assist landowners with playa preservation including CP23A, the Wetlands Reserve Program, and the Wildlife Habitat Incentive Program. This study evaluates each conservation program and weighs the economic benefits and costs of program implementation.

Ano: 2010 URL: http://purl.umn.edu/56420 The Effective Use of Limited Information: Do Bid Maximums Reduce Procurement Cost in Asymmetric Auctions? 31 Hellerstein, Daniel; Higgins, Nathaniel. Conservation programs faced with limited budgets often use a competitive enrollment mechanism. Goals of enrollment might include minimizing program expenditures, encouraging broad participation, and inducing adoption of enhanced environmental practices. We use experimental methods to evaluate an auction mechanism that incorporates bid maximums and quality adjustments. We examine this mechanism’s performance characteristics when opportunity costs are heterogeneous across potential participants, and when costs are only approximately known by the purchaser. We find that overly stringent maximums can increase overall expenditures, and that when quality of offers is important, substantial increases in offer maximums can yield a better quality-adjusted result.

Ano: 2010 URL: http://purl.umn.edu/90850 Land Retirement Program Design in the Presence of Crop Insurance Subsidies 31 Hennessy, David A.. The U.S. federal government implements environmental, biofuels and crop insurance programs that influence land use. They are not well integrated in that cost savings from crop insurance subsidies are not acknowledged when screening land for retirement or when calculating the cost of land retirement programs. We identify and evaluate an optimal benefit index for enrollment in a land retirement program that includes a sub-index to rank land according to insurance subsidy savings. All else equal, land ranked higher in the Lorenz stochastic order should be retired first.

Ano: 2009 URL: http://purl.umn.edu/52236 The Economic Impacts of Bioenergy Crop Production on U.S. Crop Production 31 Torre Ugarte, Daniel de la; Walsh, Marie E.; Shapouri, Hosein; Slinsky, Stephen P.. In response to energy security concerns, alternative energy programs such as biomass energy systems are being developed to provide energy in the 21st century. For the biomass industry to expand, a variety of feedstocks will need to be utilized. Large scale production of bioenergy crops could have significant impacts on the United States agricultural sector in terms of quantities, prices and production location of traditional crops as well as farm income. Though a number of scenarios were examined to study the impact of bioenergy crop production on the agricultural sector, two cropland scenarios are presented in this report. Under the wildlife management scenario, the analysis indicates that, at $30/dry ton (dt) for switchgrass,...

Ano: 2003 URL: http://purl.umn.edu/33997 A QUALITATIVE CHOICE ANALYSIS OF FACTORS INFLUENCING POST-CRP LAND USE DECISIONS 31 Johnson, Phillip N.; Misra, Sukant K.; Ervin, R. Terry. The future use of Conservation Reserve Program (CRP) lands is an important agricultural policy issue. To examine the effects of factors that influence landowners' post-contract use of CRP lands, a survey of Texas High Plains CRP contract holders was conducted in 1992. This study analyzes the results of the survey using a qualitative choice model. It was found that the presence of a livestock enterprise in the current contract holder's operation increases the probability of these acres remaining in the established cover. Contract holders who value the commodity base have an increased probability of returning their acres to crop production.

Ano: 1997 URL: http://purl.umn.edu/15532 AN EMPIRICAL ANALYSIS OF LOUISIANA SMALL FARMERS' INVOLVEMENT IN THE CONSERVATION RESERVE PROGRAM 31 McLean-Meyinsse, Patricia E.; Hui, Jianguo; Joseph, Randolph, Jr.. The study examines Louisiana small farmers' reasons for not participating in the Conservation Reserve Program (CRP), their awareness of the program, and their willingness to participate in the program. The results suggest that: farmers do not participate in the CRP if revenues from cropland are an important source of income, or if they are tenants; awareness is significantly related to education, income, race, and average return per acre; willingness is positively influenced by payment per acre, age, and farm status. Participation depends on whether payments per acre are comparable to the opportunity costs of removing cropland from production.

Ano: 1994 URL: http://purl.umn.edu/15170 Conservation-Compatible Practices and Programs: Who Participates? 31 Lambert, Dayton M.; Sullivan, Patrick; Claassen, Roger; Foreman, Linda F.. In recent years, the Federal Government has increased its emphasis on conservation programs that reward good stewardship on working farmland. This report examines the business, operator, and household characteristics of farms that have adopted certain conservation-compatible practices, with and without financial assistance from government conservation programs. The analysis finds that characteristics of the farm operator and household, in addition to the characteristics of the farm business, are associated with both the likelihood that a farmer will adopt certain conservation-compatible practices and the degree to which the farmer participates in different types of conservation programs. For example, operators of small farm operations and operators not...

Ano: 2006 URL: http://purl.umn.edu/7255 FACTORS AFFECTING CONSERVATION PRACTICE BEHAVIOR OF CRP PARTICIPANTS IN ALABAMA 31 Hendrix, Shannon; Wheelock, Gerald; Onianwa, Okwudili O.. This study examines the factors that affect conservation practice choices of CRP farmers in Alabama. From over 9,000 contracts enrolled in the state between 1986 and 1995, 594 were randomly selected for the study. A multiple-regression analysis was employed to analyze the data. Results indicate that education, ratio of cropland in CRP, farm size, gender, prior crop practice, and geographic location of contract had a significant influence on the choice of conservation practice adopted.

Ano: 1999 URL: http://purl.umn.edu/14730 Contract Designs and Participation in the Conservation Reserve Program in the Era of Biofuel Production 31 Wu, Feng; Guan, Zhengfei. This article has presented a farmer decision making model of participation in the Conservation Reserve Program (CRP) under the current rising bio-fuel production. The decision is specified as an optimal stopping problem and farming return is assumed following stochastic process with the uncertainty of growth rate. Nonliear Kalman filter approach is used to continuously upgrade the new information and estimate the random growth rate with the minimum error. The problem is formulated as a linear complementarity problem that is solved numerically using a fully implicit finite difference method. It is found that participation in the CRP is sensitive to financial incentive, and shortening contract length is also an effective method to promote land enrollment in...

Ano: 2009 URL: http://purl.umn.edu/51646 Conservation Reserve Program in South Dakota: Major Findings from 2007 Survey of South Dakota CRP Respondents 31 Janssen, Larry; Klein, Nicole L.; Taylor, Gary; Opoku, Emmanuel; Holbeck, Michael. This study summarizes key results from a 2007 survey completed by 753 CRP contract holders in South Dakota. Topics covered include: comparison of national and South Dakota CRP trends, key characteristics of CRP contract holders in South Dakota, current CRP management practices and overall crop/livestock management practices, and respondent assessment of relative importance of various factors affecting their CRP decisions. Projected re-enrollment rate into a new CRP contract varies from 34 percent to 63 percent of existing CRP acres, depending on scenario. Statewide, 61 percent of post-CRP acres, not re-enrolled, are projected to be used for crop production, 30 percent for grass hay or livestock production, and 9 percent for other uses.

Ano: 2008 URL: http://purl.umn.edu/37936 Impact of High Crop Prices on Environmental Quality: A Case of Iowa and the Conservation Reserve Program 31 Secchi, Silvia; Babcock, Bruce A.. Growing demand for corn due to the expansion of ethanol has increased concerns that environmentally sensitive lands retired from agricultural production into the Conservation Reserve Program (CRP) will be cropped again. Iowa produces more ethanol than any other state in the United States, and it also produces the most corn. Thus, an examination of the impacts of higher crop prices on CRP land in Iowa can give insight into what we might expect nationally in the years ahead if crop prices remain high. We construct CRP land supply curves for various corn prices and then estimate the environmental impacts of cropping CRP land through the Environmental Policy Integrated Climate (EPIC) model. EPIC provides edge-of-field estimates of soil erosion, nutrient loss,...

Ano: 2007 URL: http://purl.umn.edu/9373 The Conservation Reserve Program, Off-Farm Work, and Farm Household Technical Efficiencies 31 Chang, Hung-Hao; Boisvert, Richard N.. Using data from a national survey of farm households in the United States, this paper examines the effects of farm households’ decisions to participate in the Conservation Reserve Program (CRP) and to work off the farm on the technical efficiency of farm household production. After controlling for the self selection bias in estimating the multiple output-oriented distance functions, results show that operators’ decisions to work off the farm (both separately and combined with participation in CRP) lead to higher technical efficiencies for farm household production— implying improvements in the resource allocation between farm and other productive activities by farm households. The technical efficiencies of household production of those farm households...

Ano: 2009 URL: http://purl.umn.edu/57034 ENVIRONMENTAL CONSERVATION IN AGRICULTURE: LAND RETIREMENT VERSUS CHANGING PRACTICES ON WORKING LAND 31 Feng, Hongli; Kurkalova, Lyubov A.; Kling, Catherine L.; Gassman, Philip W.. The study develops a conceptual framework for analyzing the allocation of conservation funds via selectively offering incentive payments to farmers for enrolling in one of two mutually exclusive agricultural conservation programs: retiring land from production or changing farming practices on land that remains in production. We investigate how the existence of a pre-fixed budget allocation between the programs affects the amounts of environmental benefits obtainable under alternative policy implementation schemes. The framework is applied to a major agricultural production region using field-scale data in conjunction with empirical models of land retirement and conservation tillage adoption, and a biophysical process simulation model for the environmental...

Ano: 2004 URL: http://purl.umn.edu/18627 An Econometric Analysis of the Environmental Benefits Provided by the Conservation Reserve Program 31 Fleming, Ronald A.. Over $1.7 billion has been spent on the Conservation Reserve Program (CRP) since 1985. The purpose of this study is to show that these expenditures have aided the environment. Rather than quantify changes in environmental variables, a spatial econometric model is used to test if CRP enrollments are greater in counties with poorer environmental quality. In seven of nine regions, CRP enrollments are higher in counties with an environmental concern. This positive finding justifies past expenditures by the CRP and supports continued funding as an environmental program. The CRP is targeting current environmental concerns that will lead to future improvement.

Ano: 2004 URL: http://purl.umn.edu/43388 An Ex Post Evaluation of the Conservation Reserve, Federal Crop Insurance, and Other Government Programs: Program Participation and Soil Erosion 31 Smith, Vincent H.; Goodwin, Barry K.. Recent research has questioned the extent to which government policies, including conservation and risk management programs, have influenced environmental indicators. The impacts of income-supporting and risk management programs on soil erosion are considered. An econometric model of the determinants of soil erosion, program participation, conservation effort, and input usage is estimated. While the Conservation Reserve Program has reduced erosion an average of 1.02 tons per acre from 1982 to 1992, approximately half of this reduction has been offset by increased erosion resulting from government programs other than federally subsidized crop insurance.

Ano: 2003 URL: http://purl.umn.edu/31090 The Conservation Reserve Program in the Presence of a Working Land Alternative: Implications for Environmental Quality, Program Participation, and Income Transfer 31 Feng, Hongli; Kling, Catherine L.; Kurkalova, Lyubov A.; Secchi, Silvia; Gassman, Philip W.. The United States has invested large sums of resources in multiple conservation programs for agriculture over the past century. In this paper we focus on the impacts of program interactions. Specifically, using an integrated economic and bio-physical modeling framework, we consider the impacts of the presence of working land programs on a land retirement for an important agricultural region—the Upper Mississippi River Basin (UMRB). Compared to a land retirement only program, we find that the presence of a working land program for conservation tillage results in significantly lower predicted signups for land retirement at a given rental rate. We also find that the presence of both a large working land and land retirement program can result in more...

Ano: 2005 URL: http://purl.umn.edu/18630 AN EVALUATION OF POST CONSERVATION RESERVE PROGRAM ALTERNATIVES IN THE TEXAS HIGH PLAINS 31 Johnson, Phillip N.; Segarra, Eduardo. Four policy alternatives for CRP lands upon expiration of the current contracts in Hale county, Texas are evaluated using chance-constrained programming. It was found that if CRP contracts are extended at the current average rental rate, 40 percent of the current enrollment would be expected to return to crop production, while 66 percent would return to crop production if the program were eliminated. The results also indicate that the marginal value of CRP payments to producers is lower than the marginal value of deficiency payments.

Ano: 1995 URL: http://purl.umn.edu/15275 Potential Economic Effects of Post-CRP Land Management in Southwest North Dakota 31 Bangsund, Dean A.; Hodur, Nancy M.; Leistritz, F. Larry; Nudell, Daniel J.. The uncertain future of the Conservation Reserve Program has created substantial interest for agricultural producers, rural businesses, community leaders, sportsmen, and wildlife organizations. Many regions of the upper Great Plains have participated heavily in the CRP as evidenced by program acreage reaching land enrollment limits; however, current enrollment and re-enrollment criterion are expected to substantially reduce CRP acreage in many parts of the Great Plains. The divergence of interests between pursing post-CRP lands for agricultural production versus retaining the wildlife habitat and wildlife populations supported on CRP lands presents land owners and agricultural producers with important land management decisions over the next several years....

Ano: 2011 URL: http://purl.umn.edu/119832 Potential Economic Impacts of the Managed Haying and Grazing Provision of the Conservation Reserve Program 31 Campiche, Jody L.; Dicks, Michael R.; Shideler, David W.; Dickson, Amanda. The Food Security and Rural Investment Act of 2002 included a new provision that allowed managed haying and grazing (including the harvest of biomass), if consistent with the conservation of soil, water quality, and wildlife habitat, in return for partial reductions in the annual CRP payments. The legislation provided for managed (or limited use) haying and grazing on the CRP acreage rather than prohibiting all use. This research analyzed whether or not the alternative grazing and haying scenarios would dramatically impact the price of beef or hay, and we estimated the impact such changes would have on state economies.
