In Syria alone there are thought to be 6.5 million displaced people. The conflict has uprooted many families not once but several times. Their access to food, water, shelter and medical care is often extremely limited, and because they remain inside a conflict zone, it is hard for aid agencies to reach them.
Throughout the Syrian crisis, Lebanon, Jordan and Turkey have kept their borders open. Lebanon now hosts more than a million Syrian refugees, meaning a quarter of its total population is Syrian. The pressure on housing, education and health is causing tensions in a country which itself has a recent history of conflict.The UN data serve as a reminder, though, that other conflicts have generated huge numbers of refugees in central Africa and south Asia. Indeed, as the graph below shows, Afghanistan still accounts for the greatest number of refugees in the world, and thus its neighbor Pakistan hosts more refugees than any other nation. It is not a wonder that this region continues to be a hotbed of trouble.
