A Warning to the World

More than 11 million people in the Horn of Africa face starvation, the result of a particularly cruel mix of political turmoil and the worst drought in 60 years. The famine has caught much of the world off-guard. Hunger relief agencies are scrambling, and donors have been slow to respond.

The crisis was foreseen: Repeated drought in recent decades has been making the largely pastoral life in the drylands of East Africa unsustainable. Climate change is expected to further dry out the region. And the worst hit areas are in Somalia, a nation trapped for years in a pit of civil war, poverty, piracy and radical religion. The extremist al-Shabab movement has blocked famine aid to areas in the south and prevented residents from fleeing to find help elsewhere.

Earth Institute director Jeffrey Sachs has underscored the urgency of the need for emergency aid: A billion dollars or more is needed, "equal to $1 dollar from each person in the high-income world."

"The warning is also clear," he writes in The Guardian newspaper. "The Horn of Africa is the world's most vulnerable region, beset by extreme poverty, hunger, and global climate change, notably a drying and warming of the climate during the past quarter century. These scourges are leading to the spread of violence and war, and war is contributing to global instability. Unless we confront the challenges of the Horn of Africa at their root causes — the poverty and vulnerability of pastoralist and agro-pastoralist populations — we will face a burgeoning violence in the Horn of Africa, Yemen, and beyond."

The Earth Institute's collaboration with the UN and other agencies and governments on the Drylands Initiative in East Africa is aiming to tackle the long-term problems faced by pastoral and small-plot farmers across Djibouti, Eritrea, Ethiopia, Kenya, Somalia, Southern Sudan and Uganda. Working through the MDG Centre in Nairobi, the project focuses efforts to achieve the UN's worldwide Millennium Development Goals.

The Science Behind Drought

At the International Research Institute for Climate and Society, researchers work to predict the effects of major climate shifts, such as the El Niño-La Niña cycles and human-induced warming. At the IRI video channel, IRI climate scientist Brad Lyon and others talk about the science of predicting drought, and the role index insurance is playing in helping farmers cope.

On the State of the Planet blog, IRI's Brian Kahn writes about the role of drought in the famine, and Lakis Polycarpou of the Columbia Water Center steps back to look at "The Year of Drought and Flood."

Researchers at the Lamont-Doherty Earth Observatory have been studying drought around the world, mapping the long-term history of wet and dry periods through North America and Asia. The U.S. Southwest is in the midst of a drying spell, too, raising concerns about conflicts over water use.
