This week I was at the Australasian Fire and Emergency Services (AFAC) conference in Adelaide, presenting work from the Scientific Diversity project in the Research Forum. AFAC is a good opportunity to see people from the sector, chat about research projects, check in on the progress of various projects and, as my colleague Michael Eburn demonstrates every year, score free merchandise from the trade hall.
There were a few interesting things to mention:
- Stuart Minchin from Geoscience Australia talked about some of their current and developing ‘products,’ including Water Observations from Space, which overlays clear satellite observations of surface water since 1987. For flood-minded people, this isn’t exactly an extensive record, but the images reveal some of the ‘pulses’ in surface water generated by flooding and draught.
- Hamish Clarke from OEH NSW presented work on the ‘weather envelopes’ or ‘burn windows’ within which prescribed burns (aka hazard reduction burns) have been, and can be, completed. In short, you do the laborious work of putting together a complete record of when burns have historically happened, look at those weather characteristics, then figure out whether these conditions will increase or decrease under climate change through several models (GCMs). The results are both positive and negative, though, as Hamish stated, this uncertainty ‘hastens the need for policy response’.
- Mark Finney from the (USDA Forest Service) and Rick McRae (ACT Emergency Services Agency) both gave seminars about their respective fire behaviour projects. McRae is part of the team who identified the pyrotornadogenesis event (or fire tornado) in the 2003 Canberra bushfires. He’s a great science communicator, and laid out some of the evidence about vorticity-driven lateral spread (VLS, where fires move perpendicular to wind) from recent fires (his colleague Jason Sharples explains it all here). Finney’s response to his own prompt – ‘How do fires spread?’ – was to say ‘we don’t know,’ but they’re doing some interesting work to find out.
My other recent news is that the special issue of Settler Colonial Studies is out there in the world. Stephen Turner and I had been working on the project for a while, which morphed through various forms from conversations in 2011, to a panel at a conference in 2012, and a call for papers in 2013. The cover image of the special issue (below) is from Kakadu National Park and was taken by my friend Tim Grey. If you have any trouble getting a hold of the journal – get in touch.
