Última Spatial Considerations in Air- and Water-Quality Tradeoffs for Animal Agriculture AgEcon Gollehon, Noel R.; Aillery, Marcel P.. Total and average per ton costs of land-applying manure demonstrate the importance of spatial factors on the potential effect of policy limits for water and air emissions. Per ton costs vary with the need to transport greater distances for land application, reflecting the spatial distribution of cropland and animal production. Costs are estimated with a regional modeling framework, applied to the Chesapeake Bay watershed that integrates GIS-based spatial data within an optimization framework.

Ano: 2007 URL: http://purl.umn.edu/9848 Beyond Water-Quality Regulations for CAFOs? Manure Management Costs to Meet Air-Quality Objectives AgEcon Aillery, Marcel P.; Gollehon, Noel R.. 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.

Ano: 2005 URL: http://purl.umn.edu/19208 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.
