A Watershed-Based Economic Model of Alternative Management Practices in Southern Agricultural Systems AgEcon
Paudel, Krishna P.; Hite, Diane; Intarapapong, Walaiporn; Susanto, Dwi.
We investigated the environmental impacts of alternative cultural practices within a watershed under different water quality standards. We used experimental data on nutrient runoff to determine the optimal amount of broiler litter application in hay production in Louisiana. To compensate for the lack of experimental data, we used biophysical simulation models to find the optimal combination of agricultural best-management practices in a watershed in Mississippi. The results indicated that stricter environmental standards lower total profit potential and litter utilization.

ADOPTION OF PRECISION AGRICULTURE TECHNOLOGY IN MISSISSIPPI AgEcon
Hudson, Darren; Hite, Diane.
Precision application technology has been an important topic in agriculture in recent years. This technology has the promise to improve farm management through improved information and control over in-field variability of soil characteristics and productivity. Despite this apparent promise, recent studies have shown that adoption has been low. However, little is known about the adoption of this technology in Mississippi or the reasons for or against adoption as seen through the eyes of the producer. This survey was designed to collect basic information on producer perceptions about precision agriculture technology and to assess potential reasons for or against adoption.

AGRICULTURAL SEDIMENTATION IMPACTS ON LAKESIDE PROPERTY VALUES AgEcon
Bejranonda, Somskaow; Hitzhusen, Frederick J.; Hite, Diane.
A hedonic pricing model is developed to estimate the effects of policies to control agricultural sedimentation on lakeside property values at 15 Ohio state park lakes, Using an LA/AIDS demand system, we estimate changes in social welfare that result from upstream soil conservation practices and/or lake dredging activity, while holding other property characteristics constant. Policy simulation results suggest that lakeside residents generally have a higher willingness to pay on an annualized basis for sediment reduction from upstream soil conservation than for lake dredging. This has important implications for soil conservation policy, particularly in targeting improvements in the economic efficiency of the Conservation Reserve Program.

Assessing the Relationship Between Crop Choice and Land Use Change Using A Markov Model AgEcon
Hua, Wei; Sohngen, Brent; Hite, Diane.
There is widespread concern among environmental and agricultural interest that land use change will affect the future productivity of the agricultural industry by utilizing highly productive land for development. This paper considers the links between land use change and crop choices in order to analyze whether land use change is influencing crop choices. In order to account for potential endogeneity between crop choices and land use choices, we develop a Markov Model that allows us to capture potential endogeneity between these two choices (land use and crop choice). The Markov model is developed for the 12 Midwestern U.S. States using USDA NRI data at the county level.

COMPETING RISKS IN THE SUBURBANIZATION OF AGRICULTURAL LAND AgEcon
Hite, Diane; Sohngen, Brent; Simpson, John W.; Templeton, Josh.
The rapid change in the character of land use in traditional agricultural regions of the Midwest has led to public concern in recent years. As a result, policy makers have attempted to forge novel ways to cope with problems associated with loss of farmland and the encroachment of urban/suburban sprawl. Some of the policies that have been implemented or suggested in a number of jurisdictions include purchase of development right programs, impact fees, agricultural zoning, and preferred tax treatment for agricultural land uses, among others. In this paper, we explore the forces that promote land use change in order to help public officials make informed decisions on policy implementation.

Consumer Willingness-to-Pay for Green Energy: Results from Focus Groups AgEcon
Duffy, Patricia A.; Hite, Diane; Bransby, David; Slaton, Christa.
To find out if consumers are willing to pay a surcharge for "green energy," the Alabama Department of Agriculture and Industries hosted consumer focus groups at four locations in Alabama. Results showed that consumers were willing to pay a premium in line with the costs, but that most did not have much prior information about green energy options.

Demographic and Management Factors Affecting the Adoption and Perceived Yield Benefit of Winter Cover Crops in the Southeast AgEcon
Bergtold, Jason S.; Duffy, Patricia A.; Hite, Diane; Raper, Randy L..
The inclusion of cover crops in cropping systems brings direct and indirect costs and benefits. Farmers will adopt and utilize cover crops as long as the perceived benefit of using them is positive. This paper examines the demographic and management factors affecting the adoption and perceived benefit (in terms of improved crop yield) of using winter annual cover crops. A double selectivity model of cover crop adoption and perceived yield gain was estimated using survey data of Alabama farmers examining cover crop use and management. Results may help in understanding factors shaping farmers’ perceptions, adoption, and retention of cover crops.

Demographic and Management Factors Affecting the Perceived Benefit of Winter Cover Crops in the Southeast AgEcon
Bergtold, Jason S.; Duffy, Patricia A.; Hite, Diane; Raper, Randy L..
The inclusion of cover crops in cropping systems brings both direct and indirect costs and benefits. Farmers will adopt and continue to utilize cover crops in their production systems as long as the perceived benefit of using cover crops (e.g. increased yield, higher profits, and improved soil productivity) is positive. The perceived benefits, while partially based on actual changes, may be influenced by demographic, economic and management factors. The purpose of this paper is to examine the demographic and management factors affecting the perceived benefit, in terms of improved crop yield, of using winter annual cover crops. A tobit model is estimated using survey data of Alabama farmers examining cover crop use and management. The model examines the...

ENDOGENOUS GROWTH MODELS AND THE ENVIRONMENTAL KUZNETS CURVE: AN ANALYSIS OF GLOBAL ENVIRONMENTAL SUSTAINABILITY AgEcon
Bhattarai, Gandhi Raj; Hite, Diane; Hatch, L. Upton; Thompson, Henry.
Fertilizer consumption per cubic meter of freshwater is taken as a proxy for global water quality indicator. A global model of environmental quality for 121 countries confirms the Kuznet's hypothesis. Global turning point is reached at nearly five times the average income of all countries. Foreign Direct Investment (FDI) was significant to increase the national income. Increased aid and larger farm size per capita favored higher environmental quality, albeit insignificant. A flow of better technology and possible non-agricultural employment might help improve water quality in developing countries when their net income increases.

ESTIMATING DEMAND FOR RECREATIONAL FISHING IN ALABAMA USING TRAVEL COST MODEL AgEcon
Ojumu, Oluwagbemiga; Hite, Diane; Fields, Deacue.
Individuals and households reveal their willingness to pay to enjoy environmental and natural resource services by engaging in outdoor recreation activities. The state of Alabama and the Black-Belt region possess significant recreational fishing resources whose qualities could be improved through public and private management innovations. To measure the value of such interventions, a baseline estimate of recreational fishing demand and potential for increasing the demand by on-site improvements needs to established. Using direct mail survey, count data obtained on individual angler characteristics, expenditures on fishing equipment, and destinations and expenditures on time and travel for each trip taken. In addition, the kinds and quantities of fish...

LAND USE CHANGE AND PROPERTY TAXES: AN EMPIRICAL STUDY OF THE EFFECT OF PROPERTY TAXES ON THE TIMING OF LAND CONVERSION FROM AGRICULTURAL TO RESIDENTIAL DEVELOPMENT AgEcon
Sohngen, Brent; Hite, Diane; Templeton, Josh.
This study explores how property taxes affect the timing of development. The theoretical literature suggests that higher taxes increase the time to development, although there is some disagreement in the literature. We present a simple theoretical model to motivate an empirical model that explores how land use change decisions are made over time. A hazard model is used to predict factors that influence the time to development over an 11-year period in an urbanizing county in the Midwestern corn belt. The results suggest that higher taxes slow development, as expected. Over the 11-year period for our sample, we predict that 25% more agricultural land would have converted to development if taxes had not risen. We also find, however, that the effects are...

OPTIMAL USE OF SMOKESTACK SCRUBBER BY-PRODUCT AgEcon
Hite, Diane; Forster, D. Lynn; Rausch, Jon.
Federal legislation mandates substantial reduction of air pollution emissions from electric utilities. Utilities in Appalachia that use locally mined high-sulfur coal must choose among abatement options such as fuel mixing and smokestack scrubbing technologies. Wet scrubbers are the most frequently adopted abatement technology in Ohio. This paper investigates beneficial reuses of by-product from wet scrubbers. By-product is most often disposed of in landfills, resulting in large external costs. We combine social cost and benefit transfers with a linear optimization model to investigate potential benefits of by-product recycling. Results suggest that significant incentives exist to find beneficial uses for by-product.

THE ECONOMIC AND ENVIRONMENTAL IMPACTS OF VARIABLE RATE FERTILIZER APPLICATION: THE CASE OF MISSISSIPPI AgEcon
Intarapapong, Walaiporn; Hite, Diane; Hudson, Darren.
A number of programs have been introduced to limit environmental nonpoint pollution (NPP) associated with agricultural practices. One such program, precision agriculture, involves a range of management practices that utilize site-specific information at the field level. These practices can limit the amount of nutrient and chemical runoff to the environment because they precisely match fertilizer and pesticide application to the needs of the crop. This study uses bioeconomic modeling to investigate the environmental and economic impacts of precision agriculture technology associated with variable rate fertilizer application, as compared to a conventional, single rate application. The empirical results demonstrate that one particular precision...
