Several roads in Metro Manila were submerged in deep floods Thursday afternoon (May 31) due to strong rains. MMDA, in its official Twitter account, advised motorists and commuters to stay indoors and avoid the roads during heavy rains.

Possible reasons:

1. Deforestation
2. Lands being converted to residential
3. Rivers being blocked/diverted/ illegally settled by squatters
4. Lack of discipline among Pinoys. Tapos dito, tapon doon ng basura.

Time has changed. Extreme climatic activities are here to stay. The only thing that can be done is to mitigate the effects of torrential rains.

We pass over bridges that look wide but shallow. Come rainy days, these rivers cannot cope with the volume or rain pouring down. The solution is to keep dredging machines working practically 365 days to keep those rivers from siltation, starting from the mouth of the sea, (not upriver which voters see). In Central Luzon it is the Manila Bay, and others the Laguna Lake and the Psig River. The problem of garbage and squatters on the paths of rivers should be addressed, strictly.

But that is only part of the solution. I mentioned dredging of rivers starting from the lake and the bay. However, there is another situation that slows the flow of water to the sea and lake.

You see bridges along the way, some wide. But do you see, do you know what are beyond those bridges? On some, they end at rice fields, not really part of the rainwater draining system. They form floodwater inundating homes, not only agri lands.

On some areas, the rivers come even narrower closer to the mouths of rivers, creating a bottle neck. The results we see every heavy rainfall.

There should also be a program to desilt Dams. Siltation defeats the purpoes of Dams.

This is the big problem in Central Luzon, but from time immemorial, the government refuse to solve.

Perennial flooding in the Philippines is concentrated in the Central Luzon area. The main causes and the solutions IMO are:

1. Deforestation – the solution of course is re-forestation but because our leaders know it so well that they won’t see the effects of the solution during their lifetimes (or is it political lifetimes), they do not care about it and won’t bother to implement it.

2. Siltation of rivers – Many of the tributaries of the Pampanga river, the main river channel in Central Luzon, are still heavily silted as result of the lahar flows during the 90’s. Needless to say, de-silting is the solution. Doing it is a monumental job and, to make matters worse, is being done very slowly.

3. Politics – illegal fishponds were built even before the eruption of Mt. Pinatubo. These structures have eaten a lot of areas that used to be parts of river banks. Because the fishponds are owned by people with political influence if not owned by politicians themselves their destruction is improbable. As always, the solution is POLITICAL WILL on the part of the present crop of leaders, provincial and national. There was a time when the NPA blasted illegal fishponds in Central Luzon. But those were the days because the NPA lost its ideology and has now turned into plain banditry.

4. Corruption in government – Again, as always, the solution is the elimination of government corruption. But that is trying to reach the unreachable.

a. There have been almost a hundred contractors of the DPWH doing river dredging works in Pampanga. Almost a decade has passed since lahar stopped flowing and the works started but the rivers have barely been dredged.

b. At the height of lahar flows in the 90’s Krupp of Germany offered to dredge the Pasig-Potrero river, one of the largest tributaries of the Pampanga river, FOR FREE. One condition, however, was that the project would be managed by Krupp itself and should have a free hand in choosing its contractors. Guess what? The Ramos administration rejected the offer.

c. Also during the 90’s, the Dutch government offered a grant of 200 million pesos for the dredging of the Guagua-Pasac river. As with Krupp, the Dutch made it a condition that it would choose the contractors. Guess what? The Ramos administration again refused the grant. The reasons are obvious – government corruption.

Dredging projects, post solution cause by illegal logging.

Kung marami lang puno sa gubat sa mga kabundukan, we have minimized the siltation level of inland water bodies. Nabawasan din sana ang water na pumupunta sa mga dams.

Ngayon, we need to spend billions of pesos para sa dredging projects, which sa tingin ko masasayang din dahi in a few years or more, ganun ulit dahil wala ng puno na tumutulong sa pag-hold ng soil and prevent erosion (surface run-offs).

People are now experiencing the greediness of illegal loggers and logging firms. Gagastusan pa natin.
