Overpopulation: Another cause of flood on Metro Manila

The Department of Environment and Natural Resources (DENR) indicated that overpopulation is the primary cause of flooding in Metro Manila.

“Ang pinaka-kalaban natin ay population. Habang dumadami ang population, nag-e-encroach sa waterways. Inagawan natin yung tubig ng pupuntahan niya. Tapos ‘pag may namatay na tao, sisihin natin yung ulan,” DENR MGB director Leo Nazareno said.

From an interview with Maki Pulido of GMA News’ “24 Oras,” DENR MGB director Leo Nazareno said that natural waterways can cope with the volume of heavy rainfall but the draining of floodwaters is impeded.

Small houses in Metro Manila are increasing due to the growing population in the community. The DENR Mines and Geosciences Bureau (MGB) said that these houses are blocking the way of the natural flow of rivers and streams.

Jasareno explained how the Pasig River is unable to serve its function as the outlet of excess water from the Laguna Lake to Manila Bay. Rivers have drainage and its path so that it will not overflow but drainage that are unclogged and houses that blocks the path of the river makes flood water to rise in places like Pasig City, Marikina, Pateros, Muntinlupa, Taguig and Parañaque.

“Kasi ang Marikina River, pupunta ng Laguna Lake. And then yung Laguna Lake, pupunta ng Pasig River. So, kung barado ang Pasig River, tataas ang tubig sa Laguna Lake. ‘Yung Marikina River, tataas din,” Nasareno said.

Nazareno suggests that aside from dredging another effective solution is the relocation of squatters who populate areas at and near Pasig river and other major waterways. —AY/ELR/VS, GMA News
