I was not talking about hunger. I specifically said "mass starvation". Don't tell me there has not been any progress since the 80s, because there certainly was a lot happening since then and it's very rare to hear about mass starvation these days (except when they are created by conflicts).
Mass starvation is nearly always the result of conflict or political issues that prevent food being routed to the area of starvation (see Amartya Sen on the subject).
The famous Ethiopian famine was the direct result of a war.
