Estimating Agricultural Impacts of Expanded Ethanol Production: Policy Implications for Water Demand and Quality AgEcon
Torre Ugarte, Daniel de la; He, Lixia; Jensen, Kimberly L.; English, Burton C.; Willis, Kaelin.
Feedstock production for large scale development of the U.S. ethanol industry and introduction of cellulose–to-ethanol technology will require extensive changes in land use and impact water demand and quality. This study compares two scenarios: attaining a 60 billion gallon per year target of ethanol by 2030 and a billion gallon per year biodiesel target by 2012 with cellulose-to-ethanol technology introduced in 2012 and also delayed until 2015. Results suggest water demands and quality will vary regionally with cellulosic feedstock production. Policy emphasis on reduced and no-till practices needs to be complementary to increased crop residue use.

ESTIMATING PRICE VARIABILITY IN AGRICULTURE: IMPLICATIONS FOR DECISION MAKERS AgEcon
Ray, Daryll E.; Richardson, James W.; Torre Ugarte, Daniel de la; Tiller, Kelly.
Using a stochastic version of the POLYSYS modeling framework, an examination of projected variability in agricultural prices, supply, demand, stocks, and incomes is conducted for corn, wheat, soybeans, and cotton during the 1998-2006 period. Increased planting flexibility introduced in the 1996 farm bill results in projections of significantly higher planted acreage variability compared to recent historical levels. Variability of ending stocks and stock-to-use ratios is projected to be higher for corn and soybeans and lower for wheat and cotton compared to the 1986-96 period. Significantly higher variability is projected for corn prices, with wheat and soybean prices also being more variable. No significant change in cotton price variability is projected.

The Economic Impacts of Bioenergy Crop Production on U.S. Crop Production AgEcon
Torre Ugarte, Daniel de la; Walsh, Marie E.; Shapouri, Hosein; Slinsky, Stephen P..
In response to energy security concerns, alternative energy programs such as biomass energy systems are being developed to provide energy in the 21st century. For the biomass industry to expand, a variety of feedstocks will need to be utilized. Large scale production of bioenergy crops could have significant impacts on the United States agricultural sector in terms of quantities, prices and production location of traditional crops as well as farm income. Though a number of scenarios were examined to study the impact of bioenergy crop production on the agricultural sector, two cropland scenarios are presented in this report. Under the wildlife management scenario, the analysis indicates that, at $30/dry ton (dt) for switchgrass,...

INCENTIVES FOR SWITCHING AGRICULTURAL LAND TO CARBON SEQUESTERING NO-TILLAGE: WHAT DURATION ARE INCENTIVES NECESSARY? AgEcon
Hellwinckel, Chad M.; Larson, James A.; Torre Ugarte, Daniel de la.
Fourteen long term side-by-side tillage practice experiments were studied to analyze if no-tillage yields improved through time allowing incentives to decline. In the majority of cases, no significant increase in no-till yield is evident. Incentives may need to be permanent if switched acres are to remain using no-tillage practices.

Land Use Implications of Expanding Biofuel Demand AgEcon
Dicks, Michael R.; Campiche, Jody L.; Torre Ugarte, Daniel de la; Hellwinckel, Chad M.; Bryant, Henry L.; Richardson, James W..
The Renewable Fuel Standard mandates in the Energy Independence and Security Act of 2007 will require 36 billion gallons of ethanol to be produced in 2022. The mandates require that 16 of the 36 billion gallons must be produced from cellulosic feedstocks. The potential land use implications resulting from these mandates were examined using two methods, the POLYSYS model and a general equilibrium model. Results of the POLYSYS analysis indicated that 72.1 million tons of corn stover, 23.5 million tons of wheat straw, and 24.7 million acres would be used to produce 109 million tons of switchgrass in 2025 to meet the mandate. Results of the CGE analysis indicated that 10.9 billion bushels of corn grain, 71 million tons of corn stover, and 56,200 tons of...

Sixty Billion Gallons by 2030: Economic and Agricultural Impacts of Ethanol and Biodiesel Expansion AgEcon
Torre Ugarte, Daniel de la; English, Burton C.; Jensen, Kimberly L..
Agriculture is well positioned as a feedstock source because the fuels can be utilized with current engine technologies and are compatible with the current distribution infrastructure. Commercialization of cellulosic to ethanol technology will enable fuels to be derived from a diverse portfolio of feedstocks from numerous regions of the country. The levels of ethanol production analyzed are 10, 30, and 60 billion gallons of ethanol annually by 2010, 2020 and 2030, respectively. Impacts of producing 1 billion gallons of biodiesel production by 2012 and 1.6 billion gallons by 2030 are also projected. Overall, for the period 2007 to 2030, the estimated accumulated gains in net farm income are over $210 billion; and the accumulated potential savings in...

AN ENERGY STRATEGY BASED ON ENERGY DEDICATED CROPS OR CORN: DIFFERENTIAL ECONOMIC AND REGIONAL IMPACTS AgEcon
Torre Ugarte, Daniel de la.
The growth of the role of agriculture as a source of energy feedstock has been primarily concentrated on increasing corn use for ethanol. Alternatively, refocusing this growth in the utilization of dedicated energy crops could prove more advantageous as producers of more crops in a wider geographic area could benefit.

SUPPLY RESPONSE UNDER THE 1996 FARM ACT AND IMPLICATIONS FOR THE U.S. FIELD CROPS SECTOR AgEcon
Torre Ugarte, Daniel de la; Sanford, Scott; Skinner, Robert A.; Westcott, Paul C.; Lin, William W..
The 1996 Farm Act gives farmers almost complete planting flexibility, allowing producers to respond to price changes to a greater extent than they had under previous legislation. This study measures supply responsiveness for major field crops to changes in their own prices and in prices for competing crops and indicates significant increases in responsiveness. Relative to 1986-90, the percentage increases in the responsiveness of U.S. plantings of major field crops to a 1-percent change in their own prices are wheat (1.2 percent), corn (41.6 percent), soybeans (13.5 percent), and cotton (7.9 percent). In percentage terms, the increases in the responsiveness generally become greater with respect to competing crops' price changes. The 1996 legislation has...

SOCIAL WELFARE AND ENVIRONMENTAL DEGRADATION IN AGRICULTURE: THE CASE OF ECUADOR AgEcon
Segarra, Eduardo; Torre Ugarte, Daniel de la; Malaga, Jaime E.; Williams, Gary W..
A non-linear optimization model which maximizes total Ecuadorian social welfare, defined as the sum of consumers' and producers' surpluses for the four major crops (corn, bananas, rice and African palm) is developed to evaluate the tradeoff between welfare and environmental degradation in Ecuador. It was found that a total welfare loss of US$122 million (a 11 percent reduction - from US$ 1.112 billion to US$ 989.66 million) would be expected from a 30 percent reduction in the total pesticide load on the environment in the production of the four major crops. The distributional impacts of the welfare loss were found, however, to be significantly skewed toward the loss of consumers' surplus. Specifically, a 30 percent reduction of total pesticide load on...

Agricultural Impacts of Biofuels Production AgEcon
Walsh, Marie E.; Torre Ugarte, Daniel de la; English, Burton C.; Jensen, Kimberly L.; Hellwinckel, Chad M.; Menard, R. Jamey; Nelson, Richard G..
Analysis of the potential to supply 25% of projected 2025 U.S. transportation fuels indicates sufficient biomass resources are available to meet increased demand while simultaneously meeting food, feed, and export needs. Corn and soybeans continue to be important feedstocks for ethanol and biodiesel production, but cellulose feedstocks (agricultural crop residues, energy crops such as switchgrass, and forestry residues) will play a major role. Farm income increases, mostly because of higher crop prices. Increased crop prices increase the cost of producing biofuels.

Economic Competitiveness of Bioenergy Production and Effects on Agriculture of the Southern Region AgEcon
English, Burton C.; Torre Ugarte, Daniel de la; Walsh, Marie E.; Hellwinckel, Chad M.; Menard, R. Jamey.
The economic competitiveness of biobased industries is discussed by comparing the South relative to other regions of the United States and biomass as a feedstock source relative to fossil fuels such as coal and petroleum. An estimate of the biomass resource base is provided. Estimated changes in the agricultural sector over time resulting from the development of a large-scale biobased industry are reported, and a study on the potential to produce electricity from biomass compared with coal in the southern United States is reviewed. A biobased industry can increase net farm income and enhance economics development and job creation.
