Cases addressed include the Chernobyl and Fukushima nuclear accidents; genetically modified agricultural crops and agroecology; the growing threat of invasive alien species; mobile phones and the risk of brain tumours; and nanotechnologies. There is often little science, and very little direct hindsight, to assist in the management of these emerging technologies but the lessons from the historical case studies need to be applied if hazards are to be avoided.

Part C - Emerging issues contains the following chapters:

• Late lessons from Chernobyl, early warnings from Fukushima
  Paul Dorfman, Aleksandra Fucic and Stephen Thomas
• Hungry for innovation: pathways from GM crops to agroecology
  David Quist, Jack A. Heinemann, Anne I. Myhr, Iulie Aslaksen and Silvio Funtowicz
• Invasive alien species: a growing but neglected threat?
  Sarah Brunel, Eladio Fernández‑Galiano, Piero Genovesi, Vernon H. Heywood, Christoph Kueffer and David M. Richardson
• Mobile phones and brain tumour risk: early warnings, early actions?
  Lennart Hardell, Michael Carlberg and David Gee
• Nanotechnology — early lessons from early warnings
  Steffen Foss Hansen, Andrew Maynard, Anders Baun, Joel A. Tickner and Diana M. Bowman
