DOST introduces simplified landslides assessment procedure

La Trinidad, Benguet (20 February) -- A simplified rating system for landslide hazard assessment has been introduced by the Department of Science and Technology (DOST) to various Cordillera Stakeholders during the 2010 Northern Luzon Cluster Science and Technology Fair held at Gladiola Hall of Benguet State University last February 16.
The simplified landslide assessment is part of the DOST Grant-In-Aid Landslide project, which aims at developing a simplified and graphical hazard assessment procedure for rain-induced, shallow-depth landslides that can be used by non-experts. The proposed rating system can be applied to shallow land which slope is not beyond three meters.
The project team has already used the assessment procedure during its survey conducted on 230 landslides sites affecting communities in Kalinga and Mountain Province.
According to DOST Scientist Dr. Daniel Peckley, Jr., an individual can assess the susceptibility of his real estate property to determine its stability in terms of landslide incidents using the system. "The assessment procedure is helpful to individuals who are not familiar with assessing landslides, even a certain government agency they can adopt it and use it for their own," he said.
The said assessment procedure involves slope angle rating, material strength rating, vegetation factor, frequency of failure, land stability reduction due to presence of spring, land stability reduction based on drainage condition, and other land use factors.
"By measuring the stability of our lands, we would be able to find some ways to remedy the flaws and save our lands from erosion especially during the wet season," Peckley added.
Peckley also stressed that they will be coordinating with other government agencies and institutions, for the adoptation or utilization of the said landslide hazard assessment procedure.
"We are also open on the idea of tying up with other institutions in improving the said project, " Peckley said. The DOST is also planning to conduct training seminars on different communities, to introduce this simplified landslides assessment.
The project presentation is part of the DOST's program which also aims to educate Cordillerans on how they can contribute on climate change mitigation and adaptation procedure. (PIA) [top]
