Book excerpt: In Pamirian Crossroads and Beyond Hermann Kreutzmann offers insights in his fieldwork-based research in High Asia during four decades. A human-geographical perspective is pursued in which case studies about colonial and post-colonial boundary-making, exchange relations of mountain communities across international borders, the transformation of agricultural and pastoral practices and the effects of modernisation strategies in neighbouring countries are centred in the Hindukush, Wakhan Quadrangle, Pamirian Crossroads, Karakoram Mountains and Himalaya. Empirical evidence is augmented by in-depth archival research, thus allowing a perspective from the 19th to the 21st century. By shifting the focus to mountain peripheries and emphasising spaces in between urban centres of power in Afghanistan, Pakistan, China, and the Central Asian Republics different arenas of confrontation and effective changes emerge.
