DENR identifies landslide, flood-prone provinces

MANILA, Jan. 4 – The Department of Environment and Natural Resources (DENR) on Tuesday identified landslide and flood-prone provinces in the country.

DENR-Mines and Geo-Science Bureau (MGB) director Leo Jasareno said the landslide-prone areas are Benguet, Mountain Province, Nueva Vizcaya, Kalinga, Apayao, Southern Leyte, Abra, Marinduque, Cebu, Catanduanes and Ifugao.

He said the provinces susceptible to flooding are Pampanga, Nueva Ecija, Pangasinan, Tarlac, Maguindanao, Bulacan, Metro Manila, North Cotabato, Oriental Mindoro and Ilocos Norte.

Jasareno said they will work double time for “densification” of the geohazard maps to provide a specific mapping of villages with steep slopes and bedrocks prone to erosion which are usually on the Eastern Seabord of the country.

He said they will be spending P354 million for producing detailed maps prone to landslide and floodings with a scale of 1:10,000.

Jasareno said the geohazard maps may be used to prepare for emergencies to plan land use and to address concerns on climate change adaptation.

In early 2010, DENR-MGB started a geo-hazard mapping project to identify areas in the country that are most vulnerable to natural disasters.

The mapping project identified areas susceptible to floods, landslides, liquefaction and earthquakes.

Also taken note were structures considered hazardous and possible relocation sites in emergencies. Some 1,618 municipalities and cities were surveyed for vulnerability.

The geohazard assessment mapping of 56 municipalities/cities nationwide was completed to identify areas prone to floods, landslides and other geohazards.

This completed the geohazard assessment and mapping of the entire country with a scale of 1:50,000.

Geohazard maps and advisories were re-issued to local government units (LGUs) providing the list of critical areas that are likely to be seriously affected by natural calamities.

Information and geohazard maps were provided to agencies involved in disaster risk reduction and management such as the National Disaster Risk Reduction and Management Council and to all members of the House of Representatives and Senate of the Philippines and other stakeholders.

For transparency and public access, posting of around 498 geohazards map or around 50 percent of the total maps nationwide to the website of the Mines and Geo-Science Bureau (MGB) was done to make geohazards information more accessible to public users.

Jasareno said 2010, which follows a year of destructive typhoons, became a challenge for the Department of Environment and Natural Resources (DENR) to mitigate the effects of natural disasters in the country. (PNA)
