The routes and scales of aeolian research since Bagnold (1941). The themes focus on reductionist process research,
research that treats aeolian systems in an integrated (time/space or scale) manner, research focused at the landscape scale and
research with a strong focus on understanding the temporal history of aeolian systems. Since 2000 there has perhaps been a
growing emphasis on research that attempts to integrate all these elements and which might be termed 'earth system science'
(after Thomas and Wiggs, 2008).
