When global crises erupt - whether they are natural disasters, riots or the Ebola outbreak - we tend to immediately think big picture solutions. How will governments react? What policies and NGO’s will save the day?
But what if the solution were smaller and less centralised? In fact, new research shows that the data collected by mobile phones could be the fastest, easiest and best way to respond to crisis situations. Because we carry them everywhere, mobiles are the simplest way to track population movement and physical trends in social networks.
