“…As cellulosic ethanol production comes on line, it has been predicted that the first response of farmers will be to grow those crops on existing cropland rather than on non-cropland (e.g., (Swinton, Babcock, James, & Bandaru, 2011). Analysis of our interviews data supports this prediction.…”

Farmers' cropping decisions are a product of a complex mix of socio-economic, cultural, and natural environments in which factors operating at a number of different spatial scales affect how farmers ultimately decide to use their land in any given year or over a set of years. Some environmentalists are concerned that increased demand for corn driven by ethanol production is leading to conversion of non-cropland into corn production (which we label as "extensification"). Ethanol industry advocates counter that more than enough corn supply comes from crop switching to corn and increased yields (which we label as "intensification"). In this study, we determine whether either response to corn demand --intensification or extensification --is supported. This is determined through an analysis of land-use/land-cover (LULC) data that covers the state of Kansas and a measure of a corn demand shifter related to ethanol production --distance to the closest ethanol plant --between 2007 and 2009.

“…4) and these price increases have affected land use and cropping decisions in the agricultural community (Atkinson et al, 2011;Lubowski et al, 2008;Swinton et al, 2011). Average national crop prices rose between 2002 to 2007 by 81%, 82%, 76%, and 90% for corn, soybeans, sorghum, and wheat, respectively (Fig.…”

a b s t r a c tOver 22 million hectares (ha) of U.S. croplands are irrigated. Irrigation is an intensified agricultural land use that increases crop yields and the practice affects water and energy cycles at, above, and below the land surface. Until recently, there has been a scarcity of geospatially detailed information about irrigation that is comprehensive, consistent, and timely to support studies tying agricultural land use change to aquifer water use and other factors. This study shows evidence for a recent overall net expansion of 522 thousand ha across the U.S. (MIrAD-US), was then used to reveal relatively detailed spatial patterns of irrigation change across the nation and the HPA. Causes for the irrigation increase in the HPA are complex, but factors include crop commodity price increases, the corn ethanol industry, and government policies related to water use. Impacts of more irrigation may include shifts in local and regional climate, further groundwater depletion, and increasing crop yields and farm income.Published by Elsevier Ltd.

“…The majority of the existing literature studying the land-use change applies partial equilibrium (PE) and general equilibrium models (CGE) by simulating land-use implication of biofuels (e.g. Al-Riffai et al, 2010;Andrade de Sa et al, 2010;Beckman et al, 2011;Börjesson and Tufvesson, 2011;Havlík et al, 2011;Swinton et al, 2011;Diermeier and Schmidt, 2012).…”

Bioenergy and global land-use change

This is the first article that econometrically estimates the global land-use change impact of bioenergy. Applying time-series analytical mechanisms to fuel, biofuel and agricultural commodity prices and production, we estimate the long-run relationship between energy prices, bioenergy production and the global land-use change. Our results suggest that rising energy prices and bioenergy production significantly contribute to the global land-use change both through the direct and indirect land-use change impact. Globally, the total agricultural area yearly increases by 35 578.1 thousand ha due to increasing oil price, and by 12 125.1 thousand ha due to increasing biofuel production, which corresponds to 0.73% and 0.25% of the total worldwide agricultural area, respectively. Soya land-use change and wheat land-use change have the highest elasticities with respect to both oil price and biofuel production. In contrast, nonbiomass crops (grassland and rice) have negative land-use change elasticities. Region-specific results suggest that South America faces the largest yearly total land-use change associated with oil price increase (+10 600.7 thousand ha), whereas Asia (+8918.6 thousand ha), South America (+4024.9 thousand ha) and North America (+1311.5 thousand ha) have the largest yearly total land-use change associated with increase in biofuel production.
