Among the warring factions, human-rights violations, deaths, destruction, dislocation, and the needs of millions of refugees, Canadian Simon Hacker co-ordinates aid efforts for the World Food Programme. Here's some of what he has to navigate
Palestinian children attend a rally in solidarity with Palestinian refugees in the Yarmouk refugee camp located in the suburbs of the Syrian capital of Damascus, in Gaza City, Thursday, Jan. 16, 2014. The Yarmouk camp once housed some 160,000 Palestinian refugees from the 1948 war in Israel known by Palestinians as "Naqba," or the Catastrophe, and by Israelis as the War of Independence. The dire conditions at the Yarmouk camp are a striking example of the catastrophe unfolding in rebel-held areas blockaded by the Syrian government.

Syrian refugees walk at Quru Gusik refugee camp on the outskirts of Arbil, in Iraq's Kurdistan region, December 15, 2013. The United Nations appealed for a record $6.5-billion for Syria and its neighbours on Monday to help 16 million people, many of them hungry or homeless victims of a conflict that has lasted 33 months with no end in sight. The Syrian appeal accounted for half of an overall funding plan of $12.9 billion for 2014 to help 52 million people in 17 countries, announced by U.N. emergency relief coordinator Valerie Amos at a meeting of donor countries in Geneva.
