Why is Yemen's food crisis off the world's humanitarian radar?

Despite the initial high optimism after Ali Abdullah Saleh's fall from power, almost half of the country's population suffer from starvation, says the World Food Programme. The appeals for humanitarian help made by Oxfam and Islamic Relief to the UN resultet in a minor raise of funds. Still, instead of $38m, the UN has decided on only $586m. Suggested reasons for this reaction are lack of media coverage, associations with al-Qaida and lack of political sway as well as donor fatigue.
