Nitrate concentration in ground water is a major problem in specific agricultural areas. Using regression and neural networks, this study models nitrate concentration in ground water as a function of iron concentration in ground water, season and distance of the well from a poultry house....

The objective of this research was to predict the nitrogen-loading rate to Delaware lakes and streams using regression analysis and neural networks. Both models relate nitrogen-loading rate to cropland, soil type and presence of broiler production. Dummy variables were used to represent soil...

One source of phosphorous pollution in areas of high chicken production is runoff from fields using fertilizer from these operations. A potential solution is to feed chicken high available phosphorus (HAP) corn, reducing phosphorus in manure. This study examined consumer purchase likelihood of...

This study compares subsurface drip irrigation and sprinkler irrigation with respect to expected returns, aquifer life, nutrient utilization and accumulation in the production of irrigated corn using swine effluent and fresh groundwater from a depleting aquifer in the Oklahoma Panhandle. Most of...

Recent studies have suggested that green technologies may be a cost effective way to manage urban runoff. Literature has also suggests that there needs to be a greater empirical basis to estimate the benefits associated with social values associated with urban trees; we therefore estimate...

We explore the efficiency of allowing participants in transferable-rights programs to sell credits in multiple markets, i.e., to double dip. In a first-best economy double-dipping is efficient, but if the cap is set suboptimally, then the answer depends on the relative slopes of the marginal...

The study explores the implications of climate change for the economic costs of ecological conservation and restoration of submerged aquatic vegetation. It develops a methodological framework that addresses the key issues of uncertainty, irreversibility and space in climate change and...

This paper uses a two-good specific factors model to derive a relationship between international trade, land degradation, and welfare. Because developing countries enjoy comparative advantage in agriculture, they will export agricultural goods. We found that trade could lower steady state land...

A simultaneous model of house values, cancer mortality and total releases is simultaneously estimated to study effects of environmental health risks. Health risks include county level total releases, number of Superfund sites and cancer mortality in Southeastern U.S. Benefits of superfund...

The objective of this research is to determine the contribution of recent agricultural policy reforms in the E.U. on the use of crop protection products. Specifically, we concentrate on the 1992 CAP reforms. Our theoretical model adopts the multi-output generalization of the...
