Sensitivity Of Carbon Emission Estimates From Indirect Land-Use Change, Jerome R. F. Dumortier, Dermot J. Hayes, Miguel Carriquiry, Fengxia Dong, Xiaodong Du, Amani E. Elobeid, Jacinto F. Fabiosa, Simla Tokgoz Jul 2009

Sensitivity Of Carbon Emission Estimates From Indirect Land-Use Change, Jerome R. F. Dumortier, Dermot J. Hayes, Miguel Carriquiry, Fengxia Dong, Xiaodong Du, Amani E. Elobeid, Jacinto F. Fabiosa, Simla Tokgoz

CARD Working Papers

We analyze the sensitivity of greenhouse gas (GHG) emissions from land-use change to modifications in assumptions concerning crop area, yield, and deforestation. For this purpose, we run a modified version of the Center for Agricultural and Rural Development (CARD) Agricultural Outlook Model, which was used previously to assess the impacts of energy price increases and biofuel policy changes on land conversion. To calculate the GHG implications of agricultural activity, we use GreenAgSiM, a model developed to evaluate emissions from land conversion and agricultural production. Both models are applied to scenarios that lead to higher US ethanol production. The results are ...


Land-Use Credits To Corn Ethanol: Accounting For Distillers Dried Grains With Solubles As A Feed Substitute In Swine Rations, Jacinto F. Fabiosa Apr 2009

Land-Use Credits To Corn Ethanol: Accounting For Distillers Dried Grains With Solubles As A Feed Substitute In Swine Rations, Jacinto F. Fabiosa

CARD Working Papers

Many studies on the impact of biofuels on greenhouse gas emissions do not consider indirect land-use change and land use avoided because of co-products utilization. This paper provides estimates of the land-use credit for corn ethanol when its by-product—distillers dried grains with solubles (DDGS)—is used in swine feed rations to substitute for corn and soymeal. The range of estimates used here covers the land-use credit used in the literature. Moreover, this study departs from earlier studies because feed rations from a least-cost optimization are used rather than rations from feeding trials, and DDGS nutrient profile variability is fully ...


Land Allocation Effects Of The Global Ethanol Surge: Predictions From The International Fapri Model, Jacinto F. Fabiosa, John C. Beghin, Fengxia Dong, Amani E. Elobeid, Simla Tokgoz, Tun-Hsiang (Edward) Yu Mar 2009

Land Allocation Effects Of The Global Ethanol Surge: Predictions From The International Fapri Model, Jacinto F. Fabiosa, John C. Beghin, Fengxia Dong, Amani E. Elobeid, Simla Tokgoz, Tun-Hsiang (Edward) Yu

CARD Working Papers

We quantify the emergence of biofuel markets and its impact on U.S. and world agriculture for the coming decade using the multi-market, multi-commodity international FAPRI (Food and Agricultural Policy Research Institute) model. The model incorporates the trade-offs between biofuel, feed, and food production and consumption and international feedback effects of the emergence through world commodity prices and trade. We examine land allocation by type of crop, and pasture use for countries growing feedstock for ethanol (corn, sorghum, wheat, sugarcane, and other grains) and major crops competing with feedstock for land resources such as oilseeds. We shock the model with ...


Three Essays Concerning Agriculture And Energy, Mindy Lyn Baker Jan 2009

Three Essays Concerning Agriculture And Energy, Mindy Lyn Baker

Graduate Theses and Dissertations

This dissertation consists of three papers, each regarding a particular aspect of the relationship between energy and agriculture. The objective of the first paper is to create a model that will enhance informed policy decisions regarding the bioeconomy. A forward-looking stochastic model captures the effect of uncertainty in crude oil prices and commodity yields on biofuel industry development. Acreage limitations on feedstocks such as corn, soybeans, and switchgrass are shown to create competition for acreage among the crops. Investors in the model are rational in the sense that they engage in biofuel production only if returns exceed what they expect ...
