CLIMATE CHANGE UPDATE

The worst drought in sixty years has thrown more than 13 million people across the Horn of Africa into crisis.

In Kenya, those already living in the greatest danger have been pushed even closer to the edge.

In the arid lands, deadly inter-tribal conflict is escalating as pastoralists compete over increasingly scarce resources, as climate change accelerates drought cycles.

As weather patterns become increasingly unpredictable, small scale farmers are struggling to grow enough food.

And in Nairobi's poorest neighborhoods, residents are reduced to eating one meal a day, as the price of food spirals out of reach.

As world leaders discuss climate policy in Durban, Fault Lines travels through Kenya's drought zone. In the second part of a two-part series, we ask how US policies intersect with drought and hunger, and how the United States is responding to the emergency in the Horn of Africa.

This episode of Fault Lines first aired on Al Jazeera English on December 5, 2011
