Philippines

What the record shows

In the Philippine record, the body that measures and the body that can act on the measurement are almost never the same. The City of Manila is one of sixteen cities inside Metro Manila, so most of what happens on its streets belongs to the metropolitan authority, the national transport department, a private concessionaire or a court — which is why so many entries here are marked regional rather than citywide. That is not a coverage artefact. It is the governing fact of the place, and it explains nearly every gap the entries below document.

The sharpest illustration is EFCOS, the flood telemetry the metropolitan authority has run across the Pasig-Marikina basin since 1993 and rehabilitated with Japanese aid a decade ago. Rainfall and river levels publish live on the weather bureau's basin site against alert, alarm and critical thresholds; crews decide how many Manggahan Floodway gates to open, keyed to a gauge upstream; the authority says mountain rain gauges give roughly ninety minutes of warning. The defences those gauges warn about are procured somewhere else entirely, and in 2025 a government validation flagged 421 flood-control projects nationwide as ghosts, with the Ombudsman charging a senator, a former public works secretary and two Metro Manila district engineers with plunder in May 2026. Metro Manila measures its floods in public, minute by minute, while the works those measurements are about became the country's largest corruption case. Sensing and concrete are funded and audited separately.

A court can force the measuring and still not reach the pipes. The Pasig River was pronounced biologically dead in 1990, and in December 2008 the Supreme Court issued a continuing mandamus ordering the environment department and eleven other agencies to restore Manila Bay and its tributaries to swimmable quality and to file quarterly progress reports indefinitely — an obligation still running. The measurement arm is a unified network of sampling stations testing dissolved oxygen, biochemical oxygen demand and coliform against a fixed parameter list. The river still fails, and a 2025 peer-reviewed source-tracking study found sewage to be the dominant contributor at both river stations, 38 per cent of the downstream signal and 22 per cent upstream, with animal sources under 1 per cent. Decades of compelled reporting cannot compel a sewer.

Where the state handed the instrument to a private party, the contract shaped the outcome more than the technology did. The beep card replaced magnetic tickets on Metro Manila's three elevated rail lines in 2015, issued not by the state but by a consortium that won the fare-collection concession and paid the government for it; the card costs a non-refundable 30 pesos, unspent balances lapse a year after a four-year expiry, and reclaiming one costs 150. The operator reports 13 million cards and 3.3 billion transactions. No independent performance figure exists, and the reason is precise: the state auditor found the project was never given performance indicators to measure against. Camera traffic enforcement has the same structure and a worse incentive. Manila switched it on in December 2020 to remove the roadside stop the city argued was where bribes happened, and the contractor running the cameras and the billing took 60 to 70 per cent of every fine collected across the five participating cities. The Supreme Court restrained the scheme in August 2022 and lifted the order in 2026 only as moot, without ruling the ordinances lawful; Manila's has not restarted. Taking the enforcer off the kerb removes the kerbside bribe and creates a new party with a financial stake in how many tickets get written.

Improvising infrastructure turns out to be fast, and instrumenting it slow. The EDSA Busway was thrown down the middle of Metro Manila's main artery in barriers and paint as a pandemic measure in June 2020, and it stayed: 66.7 million passengers in 2025, about 183,000 a day on the transport department's count, up 5.8 per cent on the year. The sensing arrived four years later — 166 cameras, 21 of them AI-equipped, timing how long buses sit at stations — QR fare payment reached part of the fleet only in December 2025, an earlier card mandate collapsed within a week, and riders still reach median stations by footbridge or across live traffic. The metropolitan command centre is the same lesson at a higher altitude: operators retime signals remotely across 403 cameras and 899 km of agency fibre, and in June 2025 stripped countdown timers from 96 intersections in favour of sensor-actuated ones — yet it publishes no machine-readable data, and the cost of Metro Manila's congestion is still quoted from a 2017 survey, because nobody has measured whether any of it helped. The plate-based driving ban, running since December 1995, has no impact evaluation at all — unlike its Mexico City counterpart, which has three and no measured air-quality gain. Thirty years in, it is defined as much by its exemptions and its enforcement gaps as by the ban.

The record's most inventive work is happening far from the capital, in cities small enough that one local government owns both halves of the problem. Cauayan, a city of about 140,000, built a drone-based 3D digital twin and used it after Typhoon Ulysses in November 2020 to estimate crop and infrastructure damage and flag 7,724 families needing evacuation; its dengue project pairs mosquito traps with a camera and a neural network that counts Aedes aegypti eggs at 99.5 per cent accuracy in field testing — and its own funder lists it as field-tested, not scaled, which is the honest description of a validated sensor that is not yet a warning system. San Fernando, smaller still, runs flood telemetry and analytics from a 220-million-peso command centre. If the entries below agree on one lesson, it is that the Philippines is rarely short of measurement. What it is short of is a single authority that holds the gauge, the budget and the duty to act at the same time.
