Each morning in this Somali border town, 11-year-old Bashir Nur Salat plots his day's mission behind a crooked wire fence. Armed with only a friend's yellow school shirt, a borrowed book and toothy grin, he eyes his prize through the mesh: lunch.

Bashir lives where three crises converge — global warming, spiraling food prices and war. He, like millions of others in Somalia, are in the crosshairs of what some aid workers are calling the "The Three Cs": climate change, costs and conflict.

The worst drought in four decades in war-torn Somalia forced his family to leave their farm three months ago and to move about 100 kilometers north to the town of Dollow on the border with Ethiopia.
