PPG: Earth and Environment are now publishing a new section, intended as a complement to its long-running Classics Revisited features. Articles in this section are intended to illuminate progress in physical geography in terms of the evolution of ideas over time. They need not be focussed on any one paper or book but can involve several related publications. Unlike 'Classics' they may well focus on the more obscure, less well known but nevertheless significant aspects of the evolution of the subject.

PPG: Earth and Environment is an international journal, encompassing an interdisciplinary approach incorporating the latest developments and debates within Physical Geography and interrelated fields across the Earth, Biological and Ecological System Sciences. Contributions which review progress to date; which blend review material with new and original findings; or which introduce material, methods or techniques at the forefront of current knowledge, while setting directions for future work are welcomed. Authors need not be uncritically exhaustive in synthesizing research on a particular topic, but should concentrate on what they consider to be the most promising recent productive trends and developments which are likely to be transformative.
