Simulated hydroclimatic impacts of projected Brazilian sugarcane expansion

Matei Georgescu, David Lobell, Christopher B. Field, A. Mahalov
Geophysical Research Letters, 2013 March 1, 2013

Sugarcane area is currently expanding in Brazil, largely in response to domestic and international demand for sugar-based ethanol. To investigate the potential hydroclimatic impacts of future expansion, a regional climate model is used to simulate 5 years of a scenario in which cerrado and cropland areas (~1.1E6 km2) within south-central Brazil are converted to sugarcane. Results indicate a cooling of up to ~1.0°C during the peak of the growing season, mainly as a result of increased albedo of sugarcane relative to the previous landscape.

Direct Climate Effects of Perennial Bioenergy Crops in the United States

Matei Georgescu, David Lobell, Christopher Field
Proceedings of the National Academy of Sciences, 2011 February 28, 2011

Biomass-derived energy offers the potential to increase energy security while mitigating anthropogenic climate change, but a successful path toward increased production requires a thorough accounting of costs and benefits. Until recently, the efficacy of biomass-derived energy has focused primarily on biogeochemical consequences.

Potential Impact of U.S. Biofuels on Regional Climate

Matei Georgescu, David Lobell, Christopher Field
Geophysical Research Letters, 2009 November 11, 2009

Recent work has shown that current bio-energy policy directives may have harmful, indirect consequences, affecting both food security and the global climate system. An additional unintended but direct effect of large-scale biofuel production is the impact on local and regional climate resulting from changes in the energy and moisture balance of the surface upon conversion to biofuel crops.

Climate Effects of 30 Years of Landscape Change over the Greater Phoenix, Arizona Region: 1. Surface Energy Budget Changes

Matei Georgescu, G. Miquez-Macho, L. T. Steyaert, C. P. Weaver
Journal of Geophysical Research, 2009 March 11, 2009

This paper is part 1 of a two-part study that evaluates the climatic effects of recent landscape change for one of the nation's most rapidly expanding metropolitan complexes, the Greater Phoenix, Arizona, region. The region's landscape evolution over an approximate 30-year period since the early 1970s is documented on the basis of analyses of Landsat images and land use/land cover (LULC) data sets derived from aerial photography (1973) and Landsat (1992 and 2001).
