Sub continental drift
most issues that require bi-lateral or multi-lateral cooperation in South Asia are in disarray. Be it the recently failed Indo-Pakistan negotiations over the Baglihar dam in Kashmir or the old and vexatious controversy over the Farakka Barrage between India and Bangladesh (see: Conflict over ganga). Invariably, these issues are ecological in nature; natural resources are what these countries are beginning to scrap about.
Water is a good example. Indo-Pakistani dialogue is inconceivable sans the trappings baggage?
