Regional, Economic, and Environmental Implications of Dual Ethanol Technologies in Brazil

Submitted by Selene Victor on Thu, 12/06/2012 - 5:04pm

Climate change, food security, and energy efficiency have become universal challenges for global economic development and environmental conservation that demand in-depth multidisciplinary research. Biofuels have emerged as a decisive factor in the fight against global warming and air pollution from fossil fuel use, and they can play an important role in the development of poor as well as rich regions. In this work, we investigate the implications of biofuels for regional development in Brazil given its historic experience as an ethanol producer.

Energy Use in the U.S. Food System

Energy is an important input in growing, processing, packaging, distributing, storing, preparing, serving, and disposing of food. Analysis using the two most recent U.S. benchmark input-output accounts and a national energy data system shows that in the United States, use of energy along the food chain for food purchases by or for U.S. households increased between 1997 and 2002 at more than six times the rate of increase in total domestic energy use. This increase in food-related energy flows is over 80 percent of energy flow increases nationwide over the period.

Comprehensive evaluation of effects of straw-based electricity generation: A Chinese case

Submitted by Selene Victor on Thu, 12/06/2012 - 3:05pm

Greater use of renewable energy is being aggressively promoted to combat climate change by the Chinese government and by other governments. Agricultural straw is the kind of renewable energy source that would become a pollution source if it is not well utilized. We select the Shiliquan straw-based electricity generation project in Shandong Province, China as a case and assess environmental externalities of straw utilization in power plants by using life-cycle analysis.

Antagonistic bioenergies: Technological divergence of the ethanol industry in Brazil

Submitted by Selene Victor on Thu, 12/06/2012 - 1:55pm

We present evidence for the coexistence of two antagonistic sugarcane ethanol production technologies in Brazil, with the Southeast region of the country having relatively mechanized production processes, and the Northeast area using labor-intensive ones.We highlight the main differences between the handproduction and fully automated mechanicalmanufacturing in the Brazilian ethanol industry and examine the historical, political, and economic factors that induced this regional technology gap that is currently observed.

Land Recycling in China and its Implication for the Regional Economy

Submitted by Selene Victor on Thu, 12/06/2012 - 12:12pm

Since 2000, many cities in China have moved their large-scale manufacturing plants from urban to suburban or other less-developed regions. This inter- or intra-regional plant relocation not only leads to changes in land use patterns but also affects institutional, socioeconomic, and environmental issues both at the local and regional levels. We call this regional restructuring process land recycling, which creates critical energy, environmental,  financial, social, and political implications.

Measuring the energy consumption of China’s domestic investment from 1992 to 2007

Submitted by Selene Victor on Thu, 12/06/2012 - 11:34am

In this study, we first define the energy consumption of domestic investment as the investment-driven energy consumption (IDEC). Then, we build an energy input–output model to identify quantitatively the amounts of China’s IDEC from 1992 to 2007. We also use the model to analyze the sector distributions of the IDEC for the same time period.
