Palestinians in the Gaza Strip are eager to leave miserable tent camps and return to their homes if a long-awaited ceasefire agreement halts the Israel-Hamas war, but many will find there is nothing left and no way to rebuild.

Israeli bombardment and ground operations have transformed entire neighborhoods in several cities into rubble-strewn wastelands, with blackened shells of buildings and mounds of debris stretching away in all directions. Major roads have been plowed up. Critical water and electricity infrastructure is in ruins. Most hospitals no longer function.

And it's unclear when — or even if — much will be rebuilt.

The agreement for a phased ceasefire and the release of hostages held by Hamas-led fighters does not say who will govern Gaza after the war, or whether Israel and Egypt will lift a blockade limiting the movement of people and goods that they imposed when Hamas seized power in 2007.

The United Nations says that it could take more than 350 years to rebuild if the blockade remains.

Two-thirds of all structures destroyed

The full extent of the damage will only be known when the fighting ends and inspectors have full access to the territory. The most heavily destroyed part of Gaza, in the north, has been sealed off and largely depopulated by Israeli forces in an operation that began in early October.

Using satellite data, the United Nations estimated last month that 69% of the structures in Gaza have been damaged or destroyed, including over 245,000 homes. The World Bank estimated $18.5 billion in damage — nearly the combined economic output of the West Bank and Gaza in 2022 — from just the first four months of the war.

Israel blames the destruction on Hamas, which ignited the war with its Oct. 7, 2023, attack into Israel, killing some 1,200 people, mostly civilians, and abducting another 250. Israel's retaliatory offensive has killed over 46,000 Palestinians, more than half of them women and children, according to Gaza's Health Ministry, which does not say how many of the dead were fighters.

Israel says it has killed over 17,000 fighters, without providing evidence. The military has released photos and video footage showing that Hamas built tunnels and rocket launchers in residential areas, and often operated in and around homes, schools and mosques.

Mountains of rubble to be moved

Before anything can be rebuilt, the rubble must be removed — a staggering task in itself.

The UN estimates that the war has littered Gaza with over 50 million tons of rubble — roughly 12 times the size of the Great Pyramid of Giza. With over 100 trucks working full time, it would take over 15 years to clear the rubble away, and there is little open space in the narrow coastal territory that is home to some 2.3 million Palestinians.

Carting the debris away will also be complicated by the fact that it contains huge amounts of unexploded ordnance and other harmful materials, as well as human remains. Gaza's Health Ministry says thousands of people killed in airstrikes are still buried under the rubble.

No plan for the day after

The rubble clearance and eventual rebuilding of homes will require billions of dollars and the ability to bring construction materials and heavy equipment into the territory — neither of which is assured.

The ceasefire agreement calls for a three- to five-year reconstruction project to begin in its final phase, after all the remaining 100 hostages have been released and Israeli troops have withdrawn from the territory.

But getting to that point will require agreement on the second and most difficult phase of the deal, which still must be negotiated.

Even then, the ability to rebuild will depend on the blockade, which critics have long decried as a form of collective punishment. Israel says it is needed to prevent Hamas from rebuilding its military capabilities, noting that cement and metal pipes can also be used for tunnels and rockets.

Israel might be more inclined to lift the blockade if Hamas were no longer in power, but there are no plans for an alternative government.

The United States and much of the international community want a revitalized Palestinian Authority to govern the West Bank and Gaza with the support of Arab countries ahead of eventual statehood. But that's a nonstarter for Israel's government, which is opposed to a Palestinian state and has ruled out any role in Gaza for the Western-backed authority.

International donors are unlikely to invest in an ungoverned territory that has seen five wars in less than two decades, which means the sprawling tent camps along the coast could become a permanent feature of life in Gaza.

Billions of dollars will be needed to rebuild Gaza after the war between Israel and the Palestinian group Hamas, according to assessments from the United Nations.

Israel and Hamas agreed to a deal to halt fighting in the enclave and swap Israeli hostages for Palestinian prisoners, an official briefed on the agreement said on Wednesday.

Here is a breakdown of the destruction in Gaza from the conflict prompted by the Oct. 7, 2023 attack on Israel by Hamas, which at the time ruled the Palestinian enclave.

HOW MANY CASUALTIES ARE THERE?

The Hamas attack on Israel killed 1,200 people, according to Israeli tallies. Israel's retaliation has killed more than 46,000 people, according to Gaza's health ministry.

HOW LONG WILL IT TAKE TO CLEAR THE RUBBLE?

The United Nations warned in October that removing 42 million tons of rubble left in the aftermath of Israel's bombardment could take years and cost $1.2 billion. A UN estimate from April 2024 suggested it would take 14 years to clear the rubble.

The debris is believed to be contaminated with asbestos, with some refugee camps struck during the war known to have been built with the material. The rubble also likely holds human remains. The Palestinian Ministry of Health estimated in May that 10,000 bodies were missing under the debris.

HOW MANY BUILDINGS HAVE BEEN DESTROYED?

Rebuilding Gaza's shattered homes will take at least until 2040, but could drag on for many decades, according to a UN report released last year.

Two-thirds of Gaza's pre-war structures - over 170,000 buildings - have been damaged or flattened, according to UN satellite data (UNOSAT) in December. That amounts to around 69% of the total structures of the Gaza Strip.

Within the count are a total of 245,123 housing units, according to an estimate from UNOSAT. Currently, over 1.8 million people are in need of emergency shelter in Gaza, the UN humanitarian office said.

WHAT IS THE INFRASTRUCTURE DAMAGE?

The estimated damage to infrastructure totaled $18.5 billion as of end-January 2024, affecting residential buildings, commerce, industry, and essential services such as education, health, and energy, a UN-World Bank report said.

An update by the UN humanitarian office this month showed that less than a quarter of the pre-war water supplies were available, while at least 68% of the road network has been damaged.

HOW WILL GAZA FEED ITSELF?

More than half of Gaza's agricultural land, crucial for feeding the war-ravaged territory's hungry population, has been degraded by conflict, satellite images analyzed by the United Nations show.

The data reveals a rise in the destruction of orchards, field crops and vegetables in the Palestinian enclave, where hunger is widespread after 15 months of Israeli bombardment.

The UN Food and Agriculture Organization said last year that 15,000 cattle, or over 95%, of the total had been slaughtered or died since the conflict began and nearly half the sheep.

WHAT ABOUT SCHOOLS, UNIVERSITIES, RELIGIOUS BUILDINGS?

Palestinian data shows that the conflict has led to the destruction of over 200 government facilities, 136 schools and universities, 823 mosques and three churches. Many hospitals have been damaged during the conflict, with only 17 out of 36 units partially functional as of January, the UN humanitarian office's report showed.

Amnesty International's Crisis Evidence Lab has highlighted the extent of destruction along Gaza's eastern boundary. As of May 2024, over 90% of the buildings in this area, including more than 3,500 structures, were either destroyed or severely damaged.
