Prior state
The canal systems of the Indus and upper Ganges were engineered around a flow regime in which snow and glacier melt supplied the dry-season window that made winter wheat and dry-season rice possible. Deficits were made up from groundwater pumped on subsidized power. Entitlements between provinces, between states, and between farms and cities were fixed by mid-twentieth-century allocations and decades of litigation, and had never been reopened on hydrological grounds.
Material change
Dry-season entitlements are formally reallocated away from irrigated grain toward municipal, industrial, and cooling use. Canal commands are retired or converted to seasonal-only supply; groundwater extraction is metered and capped rather than nominally regulated; the cropping calendar shifts decisively off winter wheat and dry-season rice on the drier commands. The legal architecture of allocation, untouched for a century, is rewritten.
Why now
The melt contribution to dry-season flow declines through the decade as the low-elevation ice that buffered it finishes disappearing, moving the shortfall from bad years into normal years. Water tables beneath the most intensively pumped commands reach depths at which pumping cost exceeds crop value even with subsidized power. Urban and cooling demand in the Punjab conurbations, Karachi, and Delhi grows past the point where agricultural priority can be politically defended during shortage.
Mechanism and resistance
Reallocation proceeds through the machinery that exists: provincial water accords, canal-command administration, electricity tariff reform, and procurement policy. Resistance is the most formidable in this forecast — landholding cultivators with generations of political organization, provincial governments for whom water is sovereignty, and national doctrine treating grain self-sufficiency as strategic. Compensation, guaranteed procurement of less thirsty crops, and rural employment programs are the price of consent, and are only partly paid. Sindh's downstream position and Bangladesh's dependence on dry-season Ganges flow make each domestic reallocation an international question.
Consequences
The region becomes a structural net importer of staple grain, transferring its food security from its own hydrology to trade and reserves. Smallholders on the drier commands lose the asset value of irrigated land; larger operators with capital move to orchards, lower-water crops, and generation leases. Rural out-migration accelerates toward regional cities and feeds the mobility bargaining described above. Nutritional consequences fall on rural households whose own production formed part of their diet. The retirement of the world's largest contiguous irrigation complex is the decade's clearest case of industrial agriculture unwinding on physical grounds.
End state
Winter cereal area on the affected commands is materially reduced by formal allocation decisions rather than by drought, metered groundwater caps are in force, and the region's staple imports are a permanent feature of world trade.
Observable test
Provincial and interstate water accords governing the Indus and upper Ganges have been formally amended to cut agricultural dry-season entitlements, and winter cereal area on the affected commands shows a sustained downward break rather than year-to-year variation.
Disconfirming sign
Reallocation is repeatedly deferred, groundwater caps go unenforced, and winter cereal area is sustained through emergency pumping subsidies and interbasin transfer construction.
