Beyond Water-Quality Regulations for CAFOs? Manure Management Costs to Meet Air-Quality Objectives

Federal policy on manure management has focused on water-quality protection. However, animal agriculture is an important source of ammonia-nitrogen and other air emissions, increasing attention on air-quality concerns. Policies to address air emissions would influence both the costs of meeting water-quality objectives and environmental tradeoffs. We consider hypothetical policies at a regional level.manure management, confined animals, water quality, air quality, regional optimization, Chesapeake Bay, Environmental Economics and Policy,

ESTIMATING PRODUCER'S SURPLUS WITH THE CENSORED REGRESSION MODEL: AN APPLICATION TO PRODUCERS AFFECTED BY COLUMBIA RIVER BASIN SALMON RECOVERY

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.Resource /Energy Economics and Policy,

CONSEQUENCES OF FEDERAL MANURE MANAGEMENT PROPOSALS: COST TO SWINE OPERATIONS FROM LAND APPLYING MANURE

A manure application cost model was used with survey data to examine the costs to confined swine operations of meeting proposed mandatory nutrient management plans across regions and size classes. Sector costs are examined under alternative scenarios involving nutrient standards, and owner willingness to accept, and the use of phytase.Livestock Production/Industries,

A REGIONAL MODELING STRUCTURE FOR ASSESSING MANURE MANAGEMENT POLICIES: APPLICATION TO THE CHESAPEAKE BAY WATERSHED

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.manure management, confined livestock operations, regional optimization, Chesapeake Bay, Environmental Economics and Policy, Livestock Production/Industries,

Comparative assessment of risk mitigation options for irrigated agriculture

Presented during the USCID water management conference held on October 13-16, 2004 in Salt Lake City, Utah. The theme of the conference was "Water rights and related water supply issues."Includes bibliographical references.The impact of reallocating water from historical agricultural uses to expanding non-agricultural uses depends crucially on how reallocation occurs. This paper examines the water reallocation problem from a Federal perspective, focusing on alternative instruments to indemnify or compensate irrigators in the event of reallocation. These include insurance strategies (crop insurance, direct payments, and new financial instruments such as tradable bonds), conservation initiatives, and market-based measures (buyouts, contingent markets, and water banks). Policy mechanisms differ in the level of compensation provided, capacity to address concerns of stakeholders, and reliance on Federal outlays. No clear "winner" emerges among the potential mechanisms to mitigate foregone irrigation returns. The merits of alternative mechanisms depend on the evaluation criteria considered, site-specific conditions, and current water institutions.Proceedings sponsored by the U.S. Department of the Interior, Central Utah Project Completion Act Office and the U.S. Committee on Irrigation and Drainage

SALMON RECOVERY IN THE COLUMBIA RIVER BASIN: ANALYSIS OF MEASURES AFFECTING AGRICULTURE

The effects of salmon recovery measures on the Northwest agricultural sector are evaluated. Relevant recovery measures, such as: modified timing for dam releases, reservoir drawdown, and flow augmentation in the Columbia River basin, on the regional agricultural sector are evaluated. Combined, these measures would increase power rates, grain transportation costs, and irrigation water costs and reduce the supply of water to irrigators. We quantify these input cost and quantity changes and combine them into seven recovery scenarios for analysis. Results suggest that drawdown and/or minor reductions in irrigation water diversions would reduce producers' profits by less than 1% of baseline levels. However, the most extreme scenario-a long drawdown period combined with a large reduction in irrigation diversions-would reduce producers' profits by $35 million (2.5$35 million decline in annual profits, more than $27 million occur in southern Idaho and eastern Oregon. The federal government would bear these costs if it acquires water via voluntary transactions.Agricultural and Food Policy, Resource /Energy Economics and Policy,

MODELING MULTI-FARM SPATIAL INTERDEPENDENCE USING NATIONAL DATA COVERAGES: A REGIONAL APPLICATION TO MANURE MANAGEMENT

A regional modeling framework using national data series is developed to estimate the net cost of land applying manure under new federal guidelines for manure management. The model, applied to the Chesapeake Bay watershed, integrates GIS spatial data within an optimization model to generate manure hauling distances and costs.Livestock Production/Industries,

POLICY DIRECTIONS TO MITIGATE WATER-SUPPLY RISK IN IRRIGATED AGRICULTURE: A FEDERAL PERSPECTIVE

Water reallocation to meet mandated flow requirements and trust responsibilities, established in Federal law and water authority, can result in large uncompensated losses to irrigated agriculture. This paper discusses the nature and potential cost of water-supply interruptions due to Federal actions, and provides a comparative assessment of alternative risk-mitigation measures.Resource /Energy Economics and Policy,

CONFINED ANIMAL PRODUCTION AND MANURE NUTRIENTS

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, proposed policies that focus on land application have the potential to limit manure nutrient movement to waterways in most areas, if properly managed. However, moving manure to crop farms that formerly had not used manure will increase costs. There were about 5 percent of counties where the manure nitrogen production levels from confined animal production exceeded half the nitrogen assimilative capacity of all the cropland and pastureland in the county. These areas have the greatest need for mechanisms to encourage off-farm solutions to utilize manure as a feedstock for commercial enterprises or central processing.Livestock Production/Industries,
