Expansion of sugarcane crop in Brazil leads to local cooling
Source : greencarcongress.com
A new study led by Carnegie Institution's Department of Global Ecology has found that the expansion of sugarcane crop in Brazil in areas previously occupied by other Brazilian crops cools the local climate. It does so by reflecting sunlight back into space and by lowering the temperature of the surrounding air as the plants "exhale" cooler water. The study is published in the second issue of Nature Climate Change. The research team, led by Carnegie's Scott Loarie, is the first to quantify the direct effects on the climate from sugarcane expansion in areas of existing crop and pastureland of the cerrado, in central Brazil. Co-authors on the study are David Lobell of the Program for Food Security and the Environment at Stanford University; Gregory Asner and Christopher Field of Carnegie's Department of Global Ecology; and Qiaozhen Mu of the University of Montana.
