Battered by typhoons: Why aren’t Philippine flood control projects working?

Government data shows that just one of the smaller “flagship” projects was completed this year, while the rest have languished in their preparatory stages since at least 2018.

The DPWH also reported that 70 percent of Metro Manila’s “antiquated drainage system” was clogged with rubbish and silt, hampering flood management. It also reported that the country lacks a national flood control master plan, with only 18 scattered plans for major river basins which are “still being currently updated”.
