Ambitious nutrient reduction targets have been set for the Gippsland Lakes, Victoria but at what cost to productive agriculture? An interdisciplinary approach is addressing this question for the Moe River catchment, a dairy-dominated catchment that is a major source of pollutants to the Gippsland Lakes. Off-farm nitrogen exports are being estimated by biophysical modellers, and economists are quantifying the impact of farming systems and agricultural practices on farm profitability. This information is assembled to form the interim profit-pollution frontier for nitrogen reported in this paper, and to calculate abatement costs. Phosphorus and sediment exports will be considered in future work. This information is intended for use in a landscape-optimisation... |

Although the initial allocation of pollution permits is neutral in terms of efficiency, it does have a significant impact on distributive equity. In this paper, we examine the two main categories of permit allocation rules, the distributive and the reductive, for controlling phosphorus pollution in a small catchment in South West England. Based on the premise that the regulatory choice compromises efficiency and equity, the main result of this paper is that an allocation of permits in proportion to the intensity of environmental preferences is a “win-win” choice. The reason is that it simultaneously achieves two goals. First, it is efficient (or cost-effective) since a permit system achieves a prespecified target at a minimum abatement cost, while second,... |

Since 1985, U.S. agricultural producers have been required to practice soil conservation on highly erodible cropland and conserve wetlands as a condition of farm program eligibility. This report discusses the general characteristics of compliance incentives, evaluates their effectiveness in reducing erosion in the program's current form, and explores the potential for expanding the compliance approach to address nutrient runoff from crop production. While soil erosion has, in fact, been reduced on land subject to Conservation Compliance, erosion is also down on land not subject to Conservation Compliance, indicating the influence of other factors. Analysis to isolate the influence of Conservation Compliance incentives from other factors suggests that about... |

Corn production uses over 25 percent of the Nation's cropland and more than 40 percent of the commercial fertilizer applied to crops. Thus, corn farmers' choices of soil, nutrient, and water management systems can have a major impact not only on their own profitability, but also on the environment. If sound economic and environmental choices are to be encouraged, it may help to assess relationships between operator and farm characteristics and the adoption of management techniques by corn farmers. Data from the 1996 Agricultural Resource Management Survey (ARMS) of U.S. corn farms and producers are analyzed for this purpose, supplemented by a literature survey on factors that influence corn farm management choices. Relationships were found between certain... |
