Highlands and lowlands have multiple and diverese ecological and enironmental linkages. This note, however, is confined to economic linkages which are influenced by biophysical conditions of the highlands (mountains) and lowlands (plains). In this context, the author examines and highlights the importance of the relationship between highlands and lowlands, proposes a framework to identify economic flows, and presents approaches to operationalise the framework. Issues that should be addressed on a priority basis are posed as questions in the end.
