Karachi

Karachi's most instructive entry has no start year, because the arrangement it describes predates the label. K-Electric, the private utility that supplies the city, publishes a weekly feeder-by-feeder load-shedding schedule derived from periodic reviews of roughly 2,000 feeders for theft and bill payment: after one such review it kept 71 per cent of the network exempt from scheduled outages while high-loss feeders faced hours of daily cuts. A published rationing plan makes scarcity legible — a resident can look up their own feeder's hours — and the regulator has ruled the logic behind it unlawful, fining the company in 2024 for loss-based load-shedding of up to sixteen hours a day, because a whole feeder is switched off even where individual customers pay their bills. It issued a fresh show-cause notice in 2025. The schedule continues.

The buses arrived next, and were shaped by ownership rather than by technology. The Green Line opened to passengers on Christmas Day 2021 after years of construction delay, built for the federal government by a state infrastructure company, with fares on a stored-value card and app that also shows live bus positions. Under federal management it carried about 55,000 passengers a day; in March 2025 operations passed to the provincial government, which connected the short Orange Line that December so both run on one ticket — a single fare across two corridors that arrived not with new hardware but when one government finally ran both. Six months after the Green Line opened, the province put roughly 240 air-conditioned buses on the road as the Peoples Bus Service, adding an app in 2023 that shows live positions, routes, timings and fares. The same feed that tells a rider where the next bus is lets the province watch its contractor in real time. Neither side publishes an audited ridership figure.

The third corridor is still a building site. TransKarachi's Red Line pairs a fare and journey-planning app with live bus tracking and a dedicated biogas plant turning cattle waste into fuel for the fleet, financed by four development institutions across 26.6 kilometres. It has run years behind schedule, its Lot 2 contractor was terminated in April 2026, and completion is uncertain. Meanwhile the Safe City project took thirteen years to produce a picture: conceived in 2011, ordered launched by the Supreme Court in 2016, and nothing built while cost estimates quadrupled. The first 25 cameras went live in October 2024, and a first phase of 1,300 cameras around the Red Zone and airport corridor was declared technically complete in December 2025 — at which point the binding constraint was not hardware at all, because the cameras had been transmitting for more than a year while the authority meant to watch them was still hiring its control-room staff.

The newest entry is the one that shows most clearly what a data layer can and cannot do. Karachi's water utility supplies about 650 million gallons a day against a demand it puts at 1,200, so tankers fill the gap for whole neighbourhoods, and in February 2026 the utility folded tanker booking, complaints and billing into a single app in Urdu, English and Sindhi. The digital layer sits on a narrow base: independent reporting puts the official hydrants it books from at only 15 to 18 million gallons a day of the city's supply, illegal hydrants tap the network alongside them, and in January 2026 the mayor said the hydrant system itself should be abolished once its contracts expire. Digitising the queue does not create water — it makes official bookings legible while the system being formalised is a sliver of how the city actually gets its supply, and the mayor now wants it gone.
