Jhang
Jhang's 606,533 residents sit atop a river-fed crop machine where five sugar mills and repeated Trimmu floods keep water, acreage, and risk tightly linked.
Jhang does not merely sit near water; it bargains with it. Pakistan's 2023 census counts 606,533 residents in the city, far above the older GeoNames figure, and the municipal committee still summarizes the local economy in a few blunt nouns: sugar, cotton, wool, wheat, sugarcane, rice, and oilseeds. What those lists miss is that Jhang works less like a self-contained industrial city than like the command point of a flood-fed agricultural machine.
The machine starts with rivers. Jhang district sits around the Trimmu headworks where the Jhelum and Chenab systems meet, and that hydrology shapes both fertility and risk. Dawn's crop reporting on the district shows how strongly water availability and processing capacity steer land use: wheat remained the largest crop at 660,000 acres in 2020, rice still covered 184,000 acres, and sugarcane stayed attractive because five sugar mills operate in the district. Cotton, once a prime crop, collapsed from more than 200,000 acres to a fraction of that after repeated pest and price shocks. The point is not that Jhang grows crops. The point is that Jhang's economy keeps reallocating itself around whichever water-hungry crop can best exploit riverbank irrigation and nearby mills.
That same hydrology can flip from asset to emergency fast. In September 2025, Radio Pakistan reported a very high flood at Trimmu Barrage that affected 304 villages across Jhang district, forced about 387,476 people to safer locations, and submerged nearly 390,000 acres, including more than 281,855 acres of standing crops. That is the Wikipedia gap. Jhang's wealth comes from a river system that periodically reminds the city it is in charge only on good days. The city matters because it coordinates the trading, processing, and administrative side of that volatile agricultural basin.
The biological parallel is the earthworm. An earthworm improves soil by moving water, air, and organic matter through it, but its whole advantage depends on moisture staying within a narrow range. Jhang works the same way. Path dependence anchored cultivation around the confluence, resource allocation favors the crops and mills that best exploit available water, source-sink dynamics pull rural harvests toward the city, and phase transitions arrive whenever irrigation abundance tips into flood disaster.
