  • Biofuels: The Grassroots Solution

    May 24, 2011  //  By Wilson Center Staff
    The original version of this article, by Joan Melcher, appeared on ChinaDialogue.

    The cultivation of biofuels – fuels derived from animal or plant matter – on marginal lands could meet up to half of the world’s current fuel consumption needs without affecting food crops or pastureland, environmental engineering researchers from America’s University of Illinois have concluded following a three-year study. The findings, according to lead author Ximing Cai, have significant implications not only for the production of biofuels but also the environmental quality of degraded lands.
    The study, the final report of which was published in the Journal of Environmental Science and Technology late last year, comes at a time of increasing global interest in biomass. The International Energy Agency predicts that biomass energy’s share of global energy supply will treble by 2050, to 30 percent. In March, the UK-based International Institute for Environment and Development called on national governments to take a “more sophisticated” approach to the energy source, putting it at the heart of energy strategies and ramping up investment in new technologies and research programs.

    The University of Illinois project used cutting-edge land-use data collection methods to try to determine the potential for second-generation biofuels and perennial grasses, which do not compete with food crops and can be grown with less fertilizer and pesticide than conventional biofuels. They are considered to be an alternative to corn ethanol – a “first generation” biofuel – which has been criticized for the high amount of energy required to grow and harvest it, its intensive irrigation needs and the fact that corn used for biofuel now accounts for about 40 percent of the United States entire corn crop.

    A critical concept of the study was that it only considered marginal land, defined as abandoned or degraded or of low quality for agricultural uses, Cai, who is civil and environmental engineering professor at the University of Illinois in the mid-western United States, told ChinaDialogue.

    The team considered cultivation of three crops: switchgrass, miscanthus, and a class of perennial grasses referred to as low-impact high-diversity (LIHD).

    Biofuels: Food, Fuel, and Future?

    From the Wilson Center  //  April 4, 2011  //  By Schuyler Null
    The Wilson Center’s Program on America and the Global Economy (PAGE) together with the Brazil Institute, have held a series of conferences focused on the field of biofuels and its impact both internationally and domestically. As part of the series, PAGE has published the results of a conference held last July on the current “state-of-play” for the biofuels industry in the United States.

    In the brief, Biofuels: Food, Fuel, and Future?, C. Ford Runge and Robbin S. Johnson, of the University of Minnesota, and Calestous Juma, of Harvard University, provide context on the various federal mandates, subsidies, and policies that affect the U.S. biofuels market. They also present recommendations to improve what is now a not-so-new market, with the aim of reducing damaging effects on food prices and creating more international competition. The brief was edited by PAGE Director Kent H. Hughes and Elizabeth A. Byers.
