The carcass of a giraffe 
 
Wajir, Kenya - At first glance, the massive drought which has swept across Kenya, Somalia and Ethiopia appears to be a crisis caused entirely by nature.

As we traveled north through Kenya into one of the worst-hit areas, the lush green of the Nairobi suburbs disappeared into gray sand and dry earth. In three hours, I counted the carcasses of 27 cattle by the roadside, and one giraffe - apparently killed because the land could not sustain them. The striking images of the landscape seem to represent a deceptively simple assessment of the drought: the dirty work of Mother Nature.

"The only reason for all the suffering in this region is the lack of rain," one desperate doctor told me as he lifted up yet another severely malnourished baby so that he could be weighed. The doctor is wrong.

Witness the outbreak of famine or drought and you'll usually see that there has been an outbreak of war nearby. In this case, the lawlessless of war-torn Somalia is driving people into neighboring Kenya. In Ethiopia, high inflation and fast-rising food prices have also forced people out. Many of those refugees have been competing with the recently killed animals that we saw on our journey for water and food. Consider that and the deadly cocktail behind this current crisis doesn't look so basic. Human hands are all over this.
