Researchers in several continents have found that agriculture began not in major river valleys but up in the hills, where early farmers tended crops on alluvial fans and improved irrigation by building earth barriers across them. Here the authors reveal a similar process in the hills of Baluchistan and Khyber Pakhtunkhwa, where early farming villages overlook the plains of the Punjab and Sindh, heartland of the later Indus civilisation. Today this is a troubled border zone, with difficult access on the ground, but our researchers make exemplary use of satellite survey to map the villages in their specific local environments.
