PROBABILISTIC COST EFFECTIVENESS IN AGRICULTURAL NONPOINT POLLUTION CONTROL
Provedor de dados: 31
Autores: McSweeny,   William T.; Shortle,   James S.
Conceptual weaknesses in the use of costs of average abatement as a measure of the cost effectiveness of agricultural nonpoint pollution control are examined. A probabilistic alternative is developed. The focus is on methods for evaluating whole-farm pollution control plans rather than individual practices. As a consequence, the analysis is presented in a chance-constrained activity analysis framework because activity procedures are a practical and well developed device for screening farm planes. Reliability of control is shown to be as important as reduction targets in designing farm plans for pollution control. Furthermore, broad-axe prescriptions of technology in the form of Best Management Practices may perform poorly with respect to cost effectiveness.

REDUCING NUTRIENT APPLICATION RATES FOR WATER QUALITY PROTECTION IN INTENSIVE LIVESTOCK AREAS: POLICY IMPLICATIONS OF ALTERNATIVE PRODUCER BEHAVIOR
Provedor de dados: 31
Autores: McSweeny,   William T.; Shortle,   James S.
High rates of commercial fertilizer and animal manure application on cropland have been identified as an important cause of ground and surface water degradation in many areas of the country.  Suggested remedies are often based on the idea that fertilization levels are economically irrational for the individual farmer.  The received wisdom is that farmers could simultaneously improve their own economic well being and reduce the degradation of the ground and surface waters by fertilizing only to meet crop nutrient needs.  Rather than assuming that farmers act irrationally, this study examines the fertilization problem on a mixed crop-livestock farm from the perspective of a risk-averse farmer coping with two key uncertainties: crop yield response to nitrogen...

A FARM-LEVEL ANALYSIS OF SOIL LOSS CONTROL: MODELING THE PROBABILISTIC NATURE OF ANNUAL SOIL LOSS
Provedor de dados: 31
Autores: McSweeny,   William T.
The Conservation Compliance provision of the Food Security Act of 1985 requires all farmers who farmed highly erodible land prior to the passage of the Act to have a locally approved conservation plan fully implemented by 1995 or lose eligibility for numerous farm programs.  Soil loss estimates of various crop, tillage practices, and conservation practices, however, are stochastic in nature.  A farm planning model is suggested that allows for stochastic soil loss estimates.  The model is compared to other models used in farm level soil conservation studies.  The model shows promise as a more acceptable tool in that the farm plans are more likely to be acceptable to the farmer.

COST COMPARISONS OF ALTERNATIVE METHODS FOR PROCESSING RECYCLED WASTE NEWSPAPERS INTO FARM-ANIMAL BEDDING
Provedor de dados: 31
Autores: Beierlein,   James G.; McSweeny,   William T.; Woodruff,   Barbara A.
The United States is facing a seemingly overwhelming problem of how to dispose of its solid waste.  For disposal solutions to be viable, they must be environmentally sound and economically viable.  Processing waste newspapers for farm-animal bedding offers a successful partial solution that meets both criteria.  Centralized newspaper chopping is found to cost less than on-farm chopping.  Both chopped and unchopped waste newspapers can be economically transported considerable distances.  The use of waste newspapers for animal bedding is economically attractive at the farm level and can provide a partial solution to the solid-waste disposal problem.
