The top 7 regions creating refugees are Syria, Venezuela, Afghanistan, South Sudan, Myanmar, Somalia or Democratic Republic of Congo. None of them do so due to overpopulation, or even environmental or ecological crisis. They're all political issues.
South-eastern Mediterranean situation was caused by repeating drought since 2006 collapsing their agricultural production. A drought in 2010 in Russia reduced their grain production by 30% and doubled the price of grain during the winter 2010-2011: it was basically a death sentence to already famished people in some African countries (Centrafrique, but also Sudan at the time), but what wasn't expected was the price of oil declining sharply, making Syria, Lybia, Tunisia and Egypt and Algeria less solvent. Algeria managed, but other countries less so. What do you think these countries have in common?
Again, these famines are also entirely a socioeconomic crisis, not actual lack of food. If Sudan wasn't a terribly run place at war with itself on two fronts, it would not have food shortages. If Somalia had a functioning government at any point in the preceding two decades, it would not have food shortages. Supply chain disruptions occur all the time in the global food market, but in non-basketcase countries there's enough resiliency for this to never reach anywhere near "death sentence" territory.
>What do you think these countries have in common?
Terrible authoritarian governments that buy off its impoverished populaces with a mirage of huge food subsidies, while stealing most of the wealth of their nations for themselves.
This is a chicken-and-egg problem. Every famine has a socioeconomic component. Theoretically you could just dump food from elsewhere into every Somali village, practically you cannot, because of the lack of security.
Is it possible to build a functional government and maintain peace if food shortages are a regular thing? I am not so sure. This kind of conditions brings warlords to power, who cement economic instability, thus never alleviating food shortages. A vicious cycle.
Other countries in the same regions facing the same issues are not in the same situation. Can you be more specific about the causes and effects you seem to be alleging?
