Aid has saved lives and increased protection for civilians trapped in conflict, according to a Professor at the Graduate Institute of International and Development Studies in Geneva.

Gilles Carbonnier made the remarks at the UN while introducing his new book “Humanitarian Economics,” an emerging field of study.

But there is a flip side to providing massive aid in certain situations, he notes.

In his study, Mr Carbonnier also argues that understanding the economics behind war, disasters and terrorism can improve the humanitarian response on the ground.

He explained to Jocelyne Sambira what the title of his book meant.
