Using publicly available data on land use and transportation corridors we calculated the human footprint index for the whole of Mexico to identify large-scale spatial patterns in the anthropogenic transformation of the land surface.

Glacial reworking of paraglacial rock slope material has been inferred from long-deglaciated terrains to be an important component of glacial sediment transfer. We provide the first description from a contemporary glacial environment of the geomorphological consequences of glacier advance (of the Feegletscher Nord, Switzerland) across a paraglacial rock avalanche deposit. The landform-sediment ...

Henri Lefebvre famously seized upon the duality of the modern city: how for some it is a space of play and liberation, and for others a centre for power and repression.

From the 1920s onw...

This article reviews selected works of the major medical geographers and examines the conditions of their emergence. Only mildly concerned with the values of cartographic precision, the article lays a foundation for future investigations into the subliminal geography of the medical ...
