Irrigated acreage is an important indicator for agricultural water demand which is a major category of water use. Three methodologies were applied in this study to project irrigated acreage of major crops in Georgia from 2010 to 2050. These three methodologies show consistent results. Total...

Through a geographically weighted panel regression analysis, we demonstrate the spatially varying relationship between weather and corn yields. A balanced panel data of 958 U.S. corn production counties for the period 2002-2006 is used. The results indicate that the relationship between weather...

Future climate change will likely to increase the frequency and severity of droughts in many regions of the U.S., especially in the southwestern states, thus further will reduce the water supply in those states. On the water demand side, the population of the U.S. also moves to the southwestern...

The hypothesis underlying this analysis is that in the presence of volatile gasoline prices competitive market forces will yield alternative, less volatile fuels as substitutes. A real-option pricing approach was employed for this analysis by modeling investment under uncertainty for the case of...

This study identifies the presence of slippage and the pitfalls associated with not considering economic substitution and expansion effects in measuring changes in water demand. Based on estimates from the Georgia Flint River Basin, the analysis indicates a 13% slippage caused by disregarding...

Policy makers should consider price volatility effects when determining appropriate spending levels for alternative fuel programs.

Since the beginning of this century, China’s annual GDP growth is over 9%. This growth is fueled by large increases in energy consumption, led by a coal-dominated energy structure, and associated with higher sulfur dioxide emissions and industry dust. In 2008, China accounted for over 17% of...
