Sustainability scientists in the Julie Ann Wrigley Global Institute of Sustainability Osvaldo Sala, Christopher Boone and Billie Turner and Arizona State University student Courtney Currier recently published a journal article, “The sustainability publication gap and its implications,” in Current Opinion in Environmental Sustainability. In this journal article, the researchers demonstrate that there is a significant difference in the publication patterns of sustainability research compared to the publication patterns of well-established disciplines such as biology and physics. In those established disciplines, there is a continuous publication gradient from lower- to higher-impact-factor journals. This, however, isn’t the case for sustainability research, which tends to be published in very high- or low-impact-factor journals and with relatively few in middle-impact-factor journals. The ASU researchers speculate that this gap may reflect the significance and seriousness of sustainability problems and the youth of sustainability as a scientific field. The lack of sustainability publications in middle-impact journals could hinder communication among sustainability scientists and impede the growth of the field. If sustainability develops into a discipline similar to biology or psychology, this could spread out publications along a broader range of impact factors. However, the authors argue that creating core journals in sustainability could encourage the intellectual silos that sustainability attempts to overcome.
