Newfound enthusiasm for the latest technologies, such as drones and smartphones, to improve the way aid is provided to people in disasters may be overblown, experts warn.

The annual World Risk Report from the United Nations University (UNU) highlights the growing interest in new technologies to improve emergency response — from drones that can survey crisis-hit areas to social media networks that allow survivors to communicate with the wider world.

These can provide important information to the logisticians who organize aid delivery or health workers trying to track deadly diseases like Ebola in no-go areas, the report said.
