Here’s What to Know About the Hunger Crisis in Gaza

Six months into the Israel-Hamas war, the people of Gaza are facing a hunger crisis that the United Nations says borders on famine.

The crisis in Gaza is entirely human-made, a result of Israel’s war on Hamas and a near-complete siege of the territory, aid experts say. Conflicts were also at the root of the other two disasters in the last two decades that were classified by a global authority as famines, in Sudan and Somalia, though in those countries drought was a also significant underlying factor.

Here’s a look at how Gaza reached this point.

The food shortages in Gaza have been created by Israel’s blockade and military operations.

For years before the latest war, Gaza was subject to an Israeli blockade, backed by Egypt. Under the blockade, humanitarian aid, including food and commercial imports, was tightly restricted. Even so, levels of malnutrition among Gaza’s roughly 2.2 million people were low and comparable to those of countries in the region.

After Oct. 7, when Hamas led a deadly attack on Israel that incited the war, Israel imposed a siege and instituted much stricter controls on what could go into Gaza, stopping anything it believed could potentially benefit Hamas from entering. At the same time, Israel blocked commercial imports of food that had filled Gaza’s shops and markets.

It also bombed Gaza’s port, restricted fishing and bombed many of the territory’s farms. Airstrikes and fighting have shattered Gaza’s infrastructure and forced almost all of its population to flee their homes. That displacement, plus the destruction of businesses and a surge in prices, has made it hard for families to feed themselves.

“The food production system has been completely obliterated, and the lack of entry of emergency aid within a short time has created a free fall,” said Jens Laerke, a spokesman for the U.N. humanitarian office.

Famine has a precise definition for the United Nations and aid groups.

This week, Samantha Power, the head of the U.S. Agency for International Development, said that a famine was underway in northern Gaza, the part of the territory most cut off from aid. Her agency later said that assessment was based on data collected in March, not on new information, but that “conditions remain dire.”

That data was released by the Integrated Food Security Phase Classification, an initiative of U.N. bodies and major relief agencies that is also known as the I.P.C.,. The I.P.C. has not declared a famine in Gaza but said last month that one was imminent in the north. The body declares a famine when at least 20 percent of households face an extreme lack of food; when at least 30 percent of children suffer from acute malnutrition; and when at least two adults or four children for every 10,000 people die each day from starvation or disease linked to malnutrition.

Since 2004, when the system was set up, there have been two famines, according to that definition. In 2011, the I.P.C. declared famine in parts of Somalia, which had endured decades of conflict. Years of drought wrecked the agricultural sector and the economy, forcing many people to leave their homes in search of food. At the same time, an Islamist insurgent group blocked starving people from fleeing and forced out Western aid organizations. In all, around 250,000 people died.

Six years later, a famine was declared in parts of South Sudan. The country had suffered years of drought, but the U.N. said that the famine was human-made. Millions of people had fled because of a civil war, destroying the country’s economy, and rebel forces and government soldiers blocked aid and hijacked food trucks. Tens of thousands died.

Gaza is small and mostly urban, so food should be close at hand.

Gaza is just 25 miles long and largely urban, and there is no shortage of food on the other side of its borders, with Israel and Egypt.

Still, aid agencies have found doing their jobs difficult. Six months of war have included the killings of scores of aid workers, including seven from World Central Kitchen, the relief group founded by the chef José Andrés. Those employees were killed by an Israeli drone strike on April 1 after delivering tons of food to a warehouse.

There is a sharp disagreement in Gaza between the U.N. and the Israeli government about how much aid is entering Gaza each day, but aid organizations say they need better access, particularly to northern Gaza. The Israeli authorities have repeatedly denied permission for aid convoys to move within Gaza, they say.

Arif Husain, the chief economist at the World Food Program, said that what made the situation in Gaza so shocking was the scale and severity of the crisis and how quickly it had developed.

Israel claims it has placed no limits on aid. Critics disagree.

Critics of the way Israel is conducting the war say that the hunger crisis derives largely from Israeli restrictions on where trucks can enter and from an onerous inspection process. Some have accused Israel of slowing aid down to punish Gazans for the Oct. 7 attack.

Israeli officials say they have placed no limits on the amount of aid that can flow into Gaza. They blame the U.N., particularly UNRWA, the main agency that helps Palestinians, for failing to distribute aid effectively.

COGAT, the Israeli agency responsible for coordinating aid deliveries into Gaza, says that it has “surged” deliveries in recent days and is opening an additional entry point in northern Gaza. More broadly, the Israeli government holds Hamas responsible for all civilian suffering in Gaza. (UNRWA said last month that Israel had denied the group access to northern Gaza, though Israel has rebutted that claim.)

Governments around the world have urged Israel to address the crisis quickly. President Biden last week warned that the United States could withhold support for Israel if it did not ensure adequate aid deliveries and protect civilians. On Wednesday, Mr. Biden said that the steps Israel had taken since then were “not enough.”
