Última Determination of Least Cost Phosphorus Abatement Practices in a Watershed Under Stochastic Conditions AgEcon White, Michael J.; Stoecker, Arthur L.; Marumo, Davis; Machooka, Stella; Howry, Sierra S.; Storm, Daniel E.. Tipo: Conference Paper or Presentation Palavras-chave: Resource /Energy Economics and Policy. Ano: 2007 URL: http://purl.umn.edu/10001 The Economics of Efficient Phosphorus Abatement in a Watershed AgEcon Ancev, Tihomir; Stoecker, Arthur L.; Storm, Daniel E.; White, Michael J.. This study presents a method to determine efficient environmental targets at a watershed level. Efficient targets are devised by estimating abatement cost and cost of environmental damages and minimizing their sum. The method was applied to a case study of phosphorus pollution in a watershed in Oklahoma. Several cumulative scenarios with alternative abatement options were simulated and efficient targets were determined. As the number of abatement options at disposal to agricultural sources increased, their optimal abatement expanded relative to the abatement at the point source. Efficient targets were found to be dependent on the choice of policy that stimulates abatement.

Ano: 2006 URL: http://purl.umn.edu/8635 OPTIMAL SPATIAL ALLOCATION OF WASTE MANAGEMENT PRACTICES TO REDUCE PHOSPHORUS POLLUTION IN A WATERSHED AgEcon Ancev, Tihomir; Stoecker, Arthur L.; Storm, Daniel E.. Phosphorus pollution from excessive litter application and municipal discharges causes eutorphication of lakes in the Eucha-Spavinaw watershed in eastern Oklahoma and western Arkansas. Consequent algae blooms impair the taste of drinking water supply drawn from the watershed and reduce the recreational values of the lakes. The paper shows how GIS data based biophysical modeling can be used to derive spatially optimal, least-cost allocation of agricultural management practices to be combined with optimal wastewater treatment activity from the point source in order to achieve socially optimal phosphorus load in the watershed. The optimal level of phosphorus load is determined by equating marginal abatement with marginal damage cost. Transportation...

Ano: 2003 URL: http://purl.umn.edu/22179 Economic Analysis of Management Practices to Reduce Phosphorus Load to Lake Eucha and Spavinaw AgEcon Howry, Sierra S.; Stoecker, Arthur L.; Storm, Daniel E.; White, Michael J.. Changes in management practices are often proposed to reduce phosphorus loading from a watershed due to over application of poultry litter. This study determines the choice, location, and level of each best management practice in the watershed to meet a Total Maximum Daily Load and margins of safety at least cost.
