DILG 10 equips high-risk LGUs on hazard, risk assessment via GIS

August 23, 2018

Focusing on the high-risk local government units of Northern Mindanao, DILG 10 conducted hazard and risk-assessment using Geographic Information System (GIS), aimed to provide said LGUs further knowledge and hands-on skills on the advanced features of GIS as powerful hazard and risk assessment tool.

GIS allows the representation of reality and the simulation of different scenarios such as different flood or landslide level.

“Resilience would need science and governance,” said DILG 10 Regional Director Arnel M. Agabe during the conduct of the said activity, as he emphasized that in building resilient communities, there is a need to come up with the correct information.

“This information should be known by everyone, valued by everyone, and used by our local decision makers so that we could come up with the appropriate response, actions and plans,” the Regional Director said.

On the said activity, the LGUs were coached on how to overlay any of the following data on the Light Detection and Ranging (LiDAR) maps from Department of Science and Technology (DOST): population by purok, spot map of high risk barangays, historical disaster event, poverty data, and updated Community-Based Monitoring System (CBMS) data in order for them to come up with risk assessment/determine vulnerable population/sectors.

Participating LGUs are those with LiDAR maps based on the LGU high-risk area online survey administered by Local Governance Capability Development Division (LGCDD) from May 31, 2018-June 10, 2018.

First batch catered LGUs from Talakag, Valencia City, Mambajao, Sagay, Jimenez, Ozamiz city, Tubod, Kapatagan, Oroquieta, Plaridel, Tangub City, and Manolo Fortich. This was conducted on August 14-17, 2018 at Hotel Conchita, Cagayan de Oro City.

Further, second batch will cater LGUs from Salvador, Gingoog, Opol, Lugait, Salay, Medina, Tagoloan, and Alubijid. Training schedule is on September 11-14, 2018.

This will be participated by the LGU’s Municipal Planning and Development Coordinator (MPDC), Local Disaster Risk Reduction and Management Officer (LDRRMO), Municipal Planning and Development Office (MPDO) IT staff.

The participants are expected to be able to produce their own risk assessment using the existing available data. This risk assessment will provide a basis for long-term management decisions regading flood and landslides preparedness systems.

Moreover, a multi-hazard risk assessment is generated using GIS based on overlays of hazard, land use and population maps. Multi-hazard risk maps can serve to identify vulnerable areas for the adoption of prevention and mitigation measures, or indicate a need for action.

“We should come up with contingency plans but unless we have the science to determine the hazards and risks, then we could not come up with long term plans,” RD Agabe said. “Good thing is that we have tools such as the GIS.”
