Welcome to the new computational sustainability blog! This blog is intended to encourage interaction among researchers with various interests connected to computational sustainability. The goal is to bring together a community of researchers, educators, policy makers, and students interested in applying and developing state of the art techniques from computational sciences to help balance environmental, economic, and societal needs for sustainable development. This is also a terrific opportunity to announce the 3rd International Conference on Computational Sustainability, to be held in July 2012 in Copenhagen, Denmark. Please visit http://www.computational-sustainability.org/compsust12/ for more details, and do take advantage of this opportunity to use the blog to communicate with others interested in computational sustainability.
