| The emerging biofuel sector has drawn great interest as an alternative source of fuel for transportation. The expansion of biofuels greatly impacts world agricultural markets, since currently, the primary feedstocks for ethanol and biodiesel production are field crops and their derived products. There is great interest in the potential of countries to expand their biofuel sectors through increased production of feedstocks. The long-term potential for developing first-generation biofuels in many countries depends on a large and constant supply of feedstocks. This may be achieved in two ways: land extensification and/or land intensification. However, expansion of land area comes with a number of environmental challenges highlighted by the recent debate on... |

| There is significant policy interest in liquid biofuels with appealing prospects for energy security, farm security, poverty alleviation, and climate change. Large-scale commercial biofuel production could have far reaching implications for regional and global markets – particularly those related to energy and land use. As such, large-scale biofuels growth is likely to have significant impacts on global greenhouse gas (GHG) emissions. This paper utilizes a CGE model with explicit biofuel, land, and energy markets. The model is able to estimate the effects on the broad range of input and output markets potentially affected globally by biofuels policies. One of the most controversial issues within the biofuels debate is potential indirect changes in land use... |

| Although food quality and food safety issues seem to dominate discussion and research in Europe, price inflation and economic recession may pose questions over food abundance over the coming years. For the first time since the early seventies, market stability for a number of commodities is seriously questioned. The paper tackles the fluctuation of food prices in the last decade and the reasons behind recent record prices in a series of commodities, trying to investigate whether food shortages may create new problems, even for relatively economically stable nations. Lowering stock levels that induce price volatility, production shortfalls due to adverse conditions that are often correlated to climate change, oil prices, changing diet patterns in regions... |

| As is the case with most rural agricultural communities, western Colorado is dependent on fossil fuels transported from distant sources. This results in vulnerability to fuel supply disruptions and price shocks (Ederington et al., 2011; Yu, Wang, and Lai, 2008). A predictable and locally derived fuel source may provide stability to the agricultural production supply chain as well as to local commerce (Tareen, Wetzstein, and Duffield , 2000; Western Organization of Research Counsels, 2009). This research project evaluates the economic feasibility of bio-butanol as a locally grown biofuel in western Colorado as a means to encourage farm-level and regional energy sovereignty. |

| A mixed-integer programming model is developed to assess the economic feasibility of siting a woody biomass-based ethanol facility in the central Appalachian hardwood region. The model maximizes the net present value (NPV) of a facility over its economic life. Model inputs include biomass availability, biomass handling system type, plant investment and capacity, transportation logistics, feedstock and product pricing, project financing, and taxes. Four alternative woody biomass handling systems, which include all processes from stand to plant, are considered. Eleven possible plant locations were identified based on site selection requirements. Results showed that the optimal plant location was in Buckhannon, West Virginia. The NPV of the plant with a... |

| The need to decrease the United States’ dependency on oil has pushed ethanol to the forefront of energy sources. In the U.S., corn is used to make ethanol. Corn-based ethanol production has been profitable over the past few years, but there has been a near doubling of corn prices in late 2006 and early 2007 (Outlaw, et. al., 2007). The trend is a constant rise in prices, which has given way to ethanol production by other sources of raw materials like sugarcane. Sugarcane ethanol is the most cost-efficient biofuel available anywhere in the world, and in the United States, the government supports sugar prices. Through the US sugar policy, sugar prices are controlled, and foreign imports are severely limited. Brazil is leading the way in sugarcane ethanol,... |

| Biofuels production is expanding rapidly all over the world, driven by rising crude oil prices, the desire of countries to be energy independent, and concerns about climate change. As developed countries, especially the United States, are expanding biofuels production, developing countries are expanding their biofuels industries as well, to power their growing economies. However, developing countries must address the food security issue when they develop biofuels. As China is a developing country with rapid economic growth, population growth, significant demand for fuels, and food security concerns, it serves as a good example for studying the opportunities and challenges faced by developing countries under current conditions. This study analyzes the... |
