Contrasting Working-Land and Land Retirement Programs

A multitude of design decisions influence the performance of voluntary conservation programs. This Economic Brief is one of a set of five exploring the implications of decisions policymakers and program managers must make about who is eligible to receive payments, how much can be received, for what action, and the means by which applicants are selected. In particular, this Brief focuses on potential tradeoffs in balancing land retirement with conservation on working lands.Agricultural and Food Policy, Environmental Economics and Policy, Land Economics/Use,

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,

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,

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,

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,

AGRICULTURE IN AN ECOSYSTEMS FRAMEWORK

By broadening the definition of an ecosystem to include economic activities, can we better characterize the interactions and relationships among agricultural activities and important indicators of ecological system health? This paper addresses research approaches for assessing the role of agriculture in an ecosystems context. Environmental regulation and resource management policies have heightened the interest in understanding interactions among agricultural activities and the natural resource base, including the impacts of agriculture on environmental quality and the impacts on agriculture of ecosystem restoration efforts. What are the most meaningful indicators of environmental quality? Which agricultural practices and policies should be considered, along with which nonagricultural resource uses? Finally, does the evolving thinking about ecosystems permit us to link agricultural practices and policies more directly and meaningfully to conceptions of sustainability, of both natural and socioeconomic systems? This paper presents a brief synopsis of ecosystem management, drawing from several recent governmental initiatives. It then provides an overview of the economics of ecosystem management from the perspective of the role of agriculture; discusses two specific cases, the Pacific Northwest and South Florida; and concludes with a discussion of promising economic approaches, data needs, and caveats to those engaged in policy analysis involving ecosystem restoration.Environmental Economics and Policy,

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,

Federal Commodity Programs and Returns to Irrigation in the West

This report examines the impact of Federal commodity programs on returns to irrigation in the western United States. Returns to irrigation are defined as average returns to land, management, fixed capital, and water (above variable water cost), net of returns to dryland crop alternatives. Commodity market returns and program revenues per unit of applied irrigation water are estimated by field crop and subregion. Two representative study years - 1984 and 1987 - highlight the effect of differing commodity prices and program support levels under extreme market conditions. Aggregate returns to irrigation in western field-crop production were fairly constant over the two study years, averaging $33 per acre-foot of water. Program revenue contributions per unit-water were highest in the Southern and Northern Plains, and lowest in the Northern Mountain and Northern Pacific regions. Commodity programs had the greatest impact on returns to irrigation in rice and cotton production. Program contributions had the greatest impact on returns to irrigation in rice and cotton production. Program contributions per unit-water were relatively low for the major food and feed grains in 1984; contributions increased significantly with expanded deficiency payments and program enrollment in 1987. Under less favorable market conditions, positive returns to irrigation were largely dependent on commodity program supports.
