The Government Office for Science has launched a series of summaries about their priority research areas. The Areas of Research Interest (ARI) documents detail the most important research questions facing government departments:

Eleven ARIs have been published so far and there are more in the pipeline. They are intended as a means to engage academia in dialogue around the research questions, in order for policy development and decision making to be informed by the best available scientific evidence, research and expertise. The ARIs each include contact details, for academics and researchers who wish to communicate with the originating departments about their contents.
