A REGIONAL MODELING STRUCTURE FOR ASSESSING COSTS OF IMPLEMENTING MANURE NUTRIENT STANDARDS: APPLICATION TO THE CHESAPEAKE BAY WATERSHED AgEcon
Aillery, Marcel P.; Gollehon, Noel R.; Ribaudo, Marc.
A Chesapeake Bay Watershed manure management model estimates the minimal regional net cost of land applying manure at $76 million under a multi-year phosphorus standard, with assumed manure acceptance rate on 60 percent of cropland. The multi-year standard represents a savings of 17 percent relative to an annual phosphorus standard.

A REGIONAL MODELING STRUCTURE FOR ASSESSING MANURE MANAGEMENT POLICIES: APPLICATION TO THE CHESAPEAKE BAY WATERSHED AgEcon
Aillery, Marcel P.; Gollehon, Noel R.; Ribaudo, Marc; Breneman, Vincent E..
A modeling framework addresses manure management policies within the Chesapeake Bay watershed. Policy focus is on manure-land application at agronomic rates, as proposed under the EPA/USDA Unified Strategy. Manure-nutrient flows are assessed subject to assimilative capacity of farmland. National data bases and GIS coverages facilitate model transferability to other watersheds.

Accounting for Transaction Costs in Point/Nonpoint Water Quality Trading Programs in the Chesapeake Bay Watershed AgEcon
Ribaudo, Marc; McCann, Laura M.J..
Transaction costs are commonly identified as a major reason why so few point/nonpoint trades have occurred in water quality trading programs. We examine the transaction costs to buyers and sellers in Pennsylvania's trading program, and compare them to baseline costs.

AGRICULTURAL PRICE, QUANTITY, AND WELFARE EFFECTS OF AIR QUALITY IMPROVEMENTS AgEcon
Ribaudo, Marc; Shortle, James S..
The failure to allow for significant crop quality effects in a partial-equilibrium model can lead to misleading inferences about the price, output and welfare implications of air quality improvements. It has been observed that air pollutants such as ozone, sulphur dioxide, and nitrogen dioxide affect the yield and quality of many crops. The economic benefit from improving air quality in crop producing regions has been measured using a partial-equilibrium approach which accounts only for supply shifting yield effects. It is shown that a yield-effect only model will underestimate output increases and benefits from an air quality improvement when commodity quality improvements as well as yield increases are forthcoming.

Atrazine: Environmental Characteristics and Economics of Management AgEcon
Ribaudo, Marc; Bouzaher, Aziz.
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...

Changes in Manure Management in the Hog Sector AgEcon
Key, Nigel D.; McBride, William D.; Ribaudo, Marc.
In recent years, structural changes in the hog sector, including increasing farm size and regional shifts in production, have altered manure management practices. Over the same period, changes to the Clean Water Act, new state regulations, and increasing local conflicts over odor have influenced manure management decisions. This study uses data from two national surveys of hog farmers to examine how hog manure management practices vary with the scale of production and how these practices evolved between 1998 and 2004. The findings provide insights into the effects of structural changes and recent policies on manure management technologies and practices, the use of nutrient management plans, and manure application rates.

CONFINED ANIMAL PRODUCTION AND MANURE NUTRIENTS AgEcon
Gollehon, Noel R.; Caswell, Margriet; Ribaudo, Marc; Kellogg, Robert L.; Lander, Charles; Letson, David.
Using data from the Census of Agriculture on animal inventory and sales, we estimate manure nutrient production on farms with confined livestock. Using reported on-farm production of crops on these same farms, we estimate the nutrient uptake for major field crops and pastureland. This enables us to examine the balance between manure nutrient production and nutrient need measured by crop uptake at a farm level. Examination at alternative spatial scales, shows that 75 percent of counties in the U.S. have farms that produce more manure nutrients than can be assimilated on the farm of production (excess nitrogen).The vast majority of the counties that produce excess nitrogen have adequate land in the county to spread the manure at agronomic rates. Thus,...

CONFINED ANIMAL PRODUCTION AND MANURE NUTRIENTS AgEcon
Gollehon, Noel R.; Caswell, Margriet; Ribaudo, Marc; Kellogg, Robert L.; Lander, Charles; Letson, David.
Census of agriculture data were used to estimate manure nutrient production and the capacity of cropland and pastureland to assimilate nutrients. Most farms (78 percent for nitrogen and 69 percent for phosphorus) have adequate land on which it is physically feasible to apply the manure produced onfarm at agronomic rates. (The costs of applying manure at these rates have not been assessed). Even so, manure that is produced on operations that cannot fully apply it to their own land at agronomic rates accounts for 60 percent of the Nation's manure nitrogen and 70 percent of the manure phosphorus. In these cases, most counties with farms that produce "excess" nutrients have adequate crop acres not associated with animal operations, but within the county, on...

Do baseline requirements hinder trades in water quality trading programs? AgEcon
Ribaudo, Marc; Ghosh, Gaurav S.; Shortle, James S..
The Environmental Protection Agency and the U.S. Department of Agriculture are promoting point/nonpoint trading as a way of reducing the costs of meeting water quality goals while giving nonpoint sources a larger role in meeting those goals. Farms can create offsets or credits in a point/nonpoint trading program by implementing management practices such as conservation tillage, nutrient management, and buffer strips. To be eligible to sell credits, farmers must first comply with baseline requirements. The EPA defines a baseline as the pollutant control requirements that apply to a seller in the absence of trading. EPA guidance recommends that the baseline for nonpoint sources be management practices that are consistent with the water quality goal. A...

ECONOMIC AND ENVIRONMENTAL EFFECTS ASSOCIATED WITH REDUCING THE USE OF ATRAZINE: AN EXAMPLE OF CROSS-DISCIPLINARY RESEARCH AgEcon
Ribaudo, Marc; Hurley, Terrance M..
Restricting or eliminating the use of atrazine in the Midwest would have important economic consequences for farmers, consumers, and the environment. These consequences can only be evaluated with cooperation between economists and weed scientists. The weed control choice set available to farmers cannot be observed through deductive research. Economists and weed scientists worked together to identify all possible weed control strategies for corn and sorghum in the Midwest and to incorporate them into an economic model. An atrazine ban was found to be the costliest strategy, and a targeted, water-quality based strategy the most cost effective.

Economics of Water Quality Protection from Nonpoint Sources: Theory and Practice AgEcon
Ribaudo, Marc; Horan, Richard D.; Smith, Mark E..
Water quality is a major environmental issue. Pollution from nonpoint sources is the single largest remaining source of water quality impairments in the United States. Agriculture is a major source of several nonpoint-source pollutants, including nutrients, sediment, pesticides, and salts. Agricultural nonpoint pollution reduction policies can be designed to induce producers to change their production practices in ways that improve the environmental and related economic consequences of production. The information necessary to design economically efficient pollution control policies is almost always lacking. Instead, policies can be designed to achieve specific environmental or other similarly related goals at least cost, given transaction costs and any...

ESTIMATING THE ECONOMIC POTENTIAL FOR OFF-FARM MANURE PROCESSING AgEcon
Gollehon, Noel R.; Christensen, Lee A.; Ribaudo, Marc; Aillery, Marcel P.; Agapoff, Jean; Breneman, Vincent E..
A Chesapeake Bay Watershed manure management model estimates the minimal regional cost of land applying manure at $110 to $130 million, depending on crop producer's’ willingness to accept manure and the nutrient standard enforced. Annualized capital costs of existing industrial plants indicate that off-farm options should be considered.

Estimating Water Quality Benefits: Theoretical and Methodological Issues AgEcon
Ribaudo, Marc; Hellerstein, Daniel.
Knowledge of the benefits and costs to water users is required for a complete assessment of policies to create incentives for water quality improving changes in agricultural production. A number of benefit estimation methods are required to handle the varying nature of water quality effects. This report reviews practical approaches and theoretical foundations for estimating the economic value of changes in water quality to recreation, navigation, reservoirs, municipal water treatment and use, and roadside drainage ditches.

Impact of Environmental Policies on the Adoption of Animal Waste Management Practices in the Chesapeake Bay Watershed AgEcon
Savage, Jeff; Ribaudo, Marc.
We use data from the ERS-NASS ARMS surveys to compare the use of best management practices on poultry and livestock farms inside the watershed and outside the watershed. Animal operations within the Chesapeake Bay States were found to be adopting some important manure management practices at a greater rate than operations outside the watershed. Adoption was taking place before the implementation of the TMDL, indicating that farmers may have been acting in response to building public pressure to reduce pollution.
