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...

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...

Livestock waste management issues are of growing environmental concern in the United States and elsewhere. Lowering the quantity of nutrients excreted by pigs can ease associated environmental problems and at the same time can reduce waste management costs. Reduction in nutrient excretion can be...
