standard IHRR Seminar – Mobile Data, Environmental Extremes and Population Movement

4th October 2013, 14:00 to 15:00, Seminar Room 010, Dept of Geography, Dr Md. Nadiruzzaman, United Nations University (MRF-UNU) Project

Population movements following an environmental stress can be a huge development challenge if we do not know where people are going and at what number. Without knowledge of the locations of affected people, relief assistance is compromised. No rapid and accurate method exists to track population movements after disasters. This research learns lessons from Haiti and plans to use CDR (call data record) from the Grameen Phone, the largest cellphone operator in Bangladesh, to estimate the magnitude and trends of population movements following the Cyclone Mohasen, which swept across Bangladesh on the 20th May 2013.

Geographic positions of SIM cards were determined by the location of the mobile phone tower through which each SIM card connects when calling. We will follow daily positions of SIM cards for Barisal and Chittagang Division from 01 April to 30 June of 2013. To exclude inactivated SIM cards, we will include SIM cards that made at least one call during the time of our study. Results from the Haiti study suggest that estimates of population movements during disasters and outbreaks can be delivered rapidly and with potentially high validity in areas with high mobile phone use. This research would offer new ways to understand population movements and climate change threshold.
