This article is a transcript of the author's Keynote Address to the Fourth World Environmental Education Congress, Durban, July 2007. He has been asked to speak about environmental education research since Tbilisi, to explore what environmental education researchers might learn from this work, and look ahead to the challenges that now face them as a community engaged in doing, and using, research. The author argues that there is a need for greater openness to new approaches, and different ways of thinking and working, more understanding across cultures, and a stronger research focus on understanding the relationship between sustainability, society and learning. He concludes that, as an environmental education community, it is important to reach out to other researchers and users of research, and especially to policy-makers. He argues that this is necessary for two reasons: (1) because they need to know more about the significance of what environmental education researchers do; and (2) because environmental education researchers need to work with them if environmental education researchers are to make a significant contribution to resolving the issues the planet faces. To prepare for this talk, the author re-familiarises himself with the research literature from the past 30 years, and uses that to examine the various shifts that have taken place since then: for example, shifts of emphasis, of engagement, and of approach. A number of things are apparent from doing this, and in this address he discusses four of these: (1) conceptions of research; (2) reporting research; (3) communicating research; and (4) future research. He starts by looking at the nature of research and how that has changed.
