It is the second serious drought in the region in three years, it says.
Oxfam is calling on donors to increase aid levels to the region.
The call follows another warning on Tuesday from the UN World Food Programme, saying that more than 14 million people in the Horn of Africa needed food aid because of drought and rising food and fuel prices.
"The cost of food has escalated by up to 500% in some places, leaving people who have suffered drought after drought in utter destitution," says Oxfam's Rob McNeil, who has just returned from the Somali and Afar regions of Ethiopia.
- In Somalia, 2.6 million (35% of the population) require emergency assistance, Oxfam says. This could increase to half the population of the country (3.5 million) by the end of 2008. Between 18% and 24% of children are acutely malnourished
- In Ethiopia, the government estimates 4.6 million people are now in need of emergency food assistance. This has more than doubled from 2.2 million in need of help at the beginning of this year. Some 75,000 children are suffering from severe acute malnutrition in drought-stricken areas, the government says
- In Turkana, northern Kenya, an Oxfam survey showed 25% of children are suffering from acute malnutrition, the highest in the country
Not a pleasant post so early in the morning but this needs to be in our consciousness as we decide on our next leader. The world is bigger than the U.S. and while we represent only a few percent of the world's population we are responsible for consuming some 25% of it's resources.
