The London Review of International Law lecture is behind a paywall but Stuart has kindly put “if you’d like a copy and can’t access [it] through an institution, please email me.” The link above also takes you to a video of the lecture. Here’s the abstract:
This lecture sketches the contours of a political -legal theory of terrain. It argues that terrain is a useful concept to think the materiality of territory. Terrain is where the geopolitical and the geophysical meet, and it is therefore a helpful concept to make political -legal understandings of territory better account for the complexities of the geophysical.
