U-Spatial Brown Bag Series: Fartun Dirie, Estimating Refugee Camp Populations with Remote Sensing

5/4/17, 12:00 PM

About this event

According to the United Nations, up to 30,000 people died every month during the height of the 2011 famine which affected parts of East Africa. By late 2010, MODIS imagery from NASA’s TERRA satellite had already captured dwindling vegetation/pastures and below average precipitation for the region, signs indicative of imminent crop failure and drought. In addition to drastic changes in crop yields and water levels, the drought forced millions to search for food with most hoping to reach refugee camps run by the United Nations. One of the largest refugee camps in the world is in Dadaab, Kenya. Dadaab itself is the size of a small city and is divided into five distinct camps, Ifo, Ifo 2, Kambioos, Dagahaley, and Hagadera. It is estimated that at the height of the famine, up to 1,400 new refugees were arriving each day, most unable to enter the camp due to overcrowding; therefore, creating makeshift shelters on the outskirts.

The goal of this project was to derive accurate population estimates using high resolution imagery as well as the classification of various building structures within the study area.
