GIS vital to manage natural disasters



The use of Geographical Information System and Remote Sensing is vital to PNG in term of Managing Natural Disasters in the country.

The increase in frequencies of natural disasters in the country has prompted the Environmental Science and Geography students of the University of Papua New Guinea to propose the use of GIS and RS to better prepare people before disasters.

The environmental Science and Geography students presented a highlight of the program through a project during the recent UPNG Science Fair.

National and Provincial Disaster officers or urban planners in managing natural disasters were targeted to use the software to quickly identify possible impact areas to evacuate the affected population in an area.

Final year Environmental Science and Geography student Joshua Sasahombi said the materials involved includes ArcGIS and MapInfo software and relevant data received from the UPNG Remote Sensing Centre and the National Statistics Office.

“The ArcGis identifies vulnerable areas according to the level of impact caused by the natural disasters by categorising the impacts into high, moderate and low. The high risk areas are places that are closer to the area of destruction while the moderate risk is in between the high risk area and the low risk area. The project provides an alternative tool to assist decision makers and planners to be ready to make wise decisions so as to avoid adverse impacts on human lives, economy and infrastructure services,” said Sasahombi.

Since all the required resources are available in the country to carry out such analysis, the tool is said to be practicable.

PNG Music legend and Member of the British Empire (MBE) George Telek visited the Journalism and Public Relations strand of University of Papua New Guinea and gave an insight of his experiences in his music career. Telek said it is true that many people today in the country prefer western style music and thus contributes to the dying taste of our traditional music which involves using our traditional musical instrument. “We should be proud of our cultural heritage that we are blessed with which no other country in the world is provided to have. We are unique and our music should resemble that. When I am performing over ease, I wear my red lap lap and play my string band. I am always proud when I am out in another country performing my songs because I know I am representing PNG.” Said Telek Telek said with the current threat of
