This paper analyzes the costs and benefits of controlling groundwater pollution from agricultural use of nitrogen fertilizer in southwestern Ontario. The Village of Hensall, where nitrate concentrations have been observed above 10 mg/L in recent years, is selected as the study site.'The CREAMS...

A dynamic model is developed to analyze farmers' irrigation investment and crop choice decisions under alternative water quality protection policies. The model is applied to an empirical example in the Oklahoma High Plains. The choices of crops and irrigation systems and the resulting levels of...

Because requisite micro data frequently are unavailable, it is common practice to use aggregate data to estimate economic relationships representing the behavior of individual agents. A substantial body of literature has examined conditions under which inferences between micro and aggregate...

This nation-scale, watershed-level analysis focuses on the major trends and the spatial pattern of land use and the impact on watershed health. We estimate a simultaneous equation system to analyze the impact of land use on aquatic health in watersheds across the United States.

A leading cause of biodiversity decline is the habitat destruction associated with urban development. We use a database of county-level land use regulations to analyze the effects of local land use regulations on land use changes. We use the results of this analysis and a species-habitat...

There is broad concern that humans are transforming our environment. This transformation has potential to impact humanity as we depend on the environment ecosystem services. According to the Millennium Assessment (2005), degradation and unsustainable exploitation presently threaten over 60% of...

This study compares the environmental and economic effects of alternative targeting strategies (benefit, cost, and benefit-cost ratio targeting) for reducing nitrate-N water pollution in the Des Moines Watershed in Iowa. The objective is achieved by applying an integrated modeling system to...
