For months we have been following increasingly urgent reports about food scarcity, rising prices and vulnerable populations. Last week, the World Food Program said the crisis is a silent tsunami that is "threatening to plunge more than 100 million people on every continent into hunger."

The World Food Program says it has never seen a crisis of this proportion. Analysts expect it will be difficult to reverse in the short term. The Financial Times says humanitarian aid at levels comparable to Indonesia's 2004 tsunami response will be needed to prevent the starvation of millions.

For Mercy Corps the increase in food prices is hurting the very people our program staff around the world are working to support.

Reports from those working most closely with affected communities confirm that the situation is dire — and has the potential to grow much worse.

Penny Anderson, Mercy Corps' food security program officer, told OPB radio: "I've been working with Mercy Corps for over eight years now and I have never seen anything like it."

In Niger, prices of bread, powdered milk and wheat flour have spiked, exacerbating the West African nation's precarious food situation. Currently about two-thirds of the population is at serious risk, with shortages pushing the country closer to famine.

In Syria, spiraling food prices have forced Mercy Corps to cut back on the amount of food we can buy and distribute to hundreds of Iraqi refugee families.

In Tajikistan, where Mercy Corps recently distributed blankets and generators to help residents keep warm during an unusually harsh winter, about 40 percent of households in the Rasht Valley are down to no more than one warm meal a day. Neighboring Kazakhstan has suspended wheat exports — shutting off Tajikistan's primary supply of the grain.

Like several other humanitarian aid agencies, Mercy Corps has established a Global Food Crisis fund to help its field teams respond to needs arising from the worst global food crisis in recent memory.

As tensions continue to run high, Mercy Corps warns that further chaos and violence in Kenya, long a bastion of regional stability, could push neighboring East African countries toward new humanitarian crises.

Our colleague Matt Lovick states, "historically, Kenya has been the hub that allowed goods and assistance to reach these land-locked, war-torn places," said Matt Lovick, Mercy Corps’ Nairobi-based East Africa regional program director. "Its importance in fostering and maintaining stability in this region cannot be underestimated."

If hostilities escalate in Kenya, neighboring economies could suffer immediately from a shortage of critical resources. Markets, planting seasons and access to food could all be severely disrupted, increasing the risks for communities already on the brink of disaster.
