Habagat” (Southwest monsoon) brings heavy rainfall, which results in flooding in Metro Manila and close by provinces. Have we tailored to this new norm? And even higher, have we realized our classes?
Our latest expertise with Supertyphoon “Carina” and Hurricane “Enteng,” which enhanced the impacts of habagat, solely proves that the world’s local weather has modified drastically due to our use of fossil fuels, which emit heat-trapping gases blamed for local weather change.

Habagat has grow to be greater than only a seasonally prevailing wind that blows from June to October. It’s a disruptive climate system that has grown in ferocity through the years, buying typhoon-like impacts since 2012, when most of Metro Manila grew to become a waterlogged zone as a consequence of torrential rains that overwhelmed the capital area’s pumping stations.
That 12 months, Luzon was battered by torrential rains and thunderstorms for eight days straight, from Aug. 1 to eight, and the sky remained darkish and misty for days after. Though the toughest hit was Metro Manila, Habagat 2012 minimize a large swath that inundated the Calabarzon area and Central Luzon with heavy rainfall. It didn’t assist that Typhoons “Gener” and “Helen” additional strengthened Habagat 2012, which dumped extra rain into the already saturated areas in Luzon.
In that 12 months, too, the federal government acknowledged the rising helplessness of residents of the capital and close by provinces because of the unpredictability of habagat and the devastating influence of over a dozen typhoons that hit the nation yearly.

Though not thought of a storm by definition, Habagat 2012 led to the deaths of 109 folks and left behind a path of destruction that value the nation P3 billion, in response to the Nationwide Catastrophe Threat Discount and Administration Council.
Working as a reporter for the Inquirer at the moment, I coated then President Benigno Aquino III as he made a four-hour swing by means of evacuation facilities in Nangka, Marikina, Bagong Silangan, Quezon Metropolis, Gen. T. de Leon, Valenzuela and Poblacion, Navotas. (Learn “3 antiflood initiatives to rise in Laguna, Marikina, Camanava” (8/10/2012) at https://tinyurl.com/d3hzzjfp).
Grasp plan. Quick-forward to 2024, the Division of Public Works and Highways asserts that there isn’t any built-in grasp plan for flood management in Metro Manila regardless of the billions of pesos beforehand allotted for it.
The 5,500 accomplished initiatives, mentioned Public Works Secretary Manuel Bonoan, have been simply “fast aid initiatives and engineering interventions everywhere in the nation that aren’t a part of the grasp plan.”
However this piecemeal method to mitigating flooding is exactly what our authorities has deserted for the reason that Aquino administration after Habagat 2012, prompted by scientific findings that local weather change will trigger chaos within the coming years. And flooding is probably the most vital problem dealing with Metro Manila, the place many areas are under sea stage.
Along with upgrading the pumping stations operated by the Metropolitan Manila Growth Authority, the Aquino administration had deliberate to put in embankments and catch basins within the Marikina watershed, and an 8-kilometer dike within the Camanava (Caloocan, Malabon, Navotas, and Valenzuela) space, and a ring-road dike alongside Laguna de Bay.
In 2012, a P351-billion long-term flood administration grasp plan was authorized to flesh out these plans, which embody the proposed Marikina Dam, Parañaque Spillway, and Manggahan Management Gate Construction, which may block floodwaters from Sierra Madre from getting into Pasig and close by cities.
If these mega infrastructure initiatives had been executed as deliberate, the grasp plan would have regularly alleviated the flood-prone jap, northern, and southern areas of the Nationwide Capital Area throughout habagat.
Scientists have lengthy warned that excessive climate occasions will grow to be more and more frequent because the local weather disaster accelerates, and that “world warming really adjustments the properties of precipitation when it comes to frequency, depth, and period,” CNN quoted Chu Jung-eun, an atmospheric and local weather scientist on the Metropolis College of Hong Kong in 2023.
However following the onslaught of Carina in July this 12 months, Bonoan admitted in a radio interview that there was a grasp plan, though solely lower than 30 % of it had been accomplished. Why did Bonoan change his tune when he confronted the Senate in August?
Even Surigao del Sur Rep. Romeo Momo issued an announcement final July 26 confirming the existence of a $500-million Metro Manila Flood Administration Challenge being funded by the World Financial institution and the Asian Infrastructure Funding Financial institution. Nonetheless, “most of the initiatives are but to be bidded out and a few are nonetheless ongoing. We have to double time with our flood infrastructure initiatives. The cash is already obtainable.” (Extra on the grasp plan in my subsequent column.)
