Gaza is filled with more debris and rubble than Ukraine, the UN said Wednesday, with the mammoth task of clearing it made all the more costly and dangerous by the sheer amount of asbestos and unexploded ordnance.
Six months into the war between Israel and Hamas, the United Nations Mine Action Service (UNMAS) estimated the amount of debris in the Gaza Strip at 37 million tons in mid-April, or 300 kilograms per square meter.
"Gaza has more rubble than Ukraine, and to put that in perspective, the Ukrainian front line is 600 miles (nearly 1,000 kilometers) long, and Gaza is 25 miles (40 km) long," said Mungo Birch, head of the UNMAS program in the Palestinian territories.
But the volume of rubble is not the only problem, said UNMAS.
"This rubble is likely heavily contaminated with UXO (unexploded ordnance), but its clearance will be further complicated by other hazards in the rubble," Birch told journalists in Geneva.
"There's estimated to be over 800,000 tonnes of asbestos, for instance, alone in the Gaza rubble." The cancer-causing mineral used in construction requires special precautions when handling.
It is generally estimated that 10 to 15 percent of the munitions fired do not explode on impact and therefore represent a lasting danger for civilian populations.
New approaches needed
Birch said he hoped UNMAS, which works to mitigate the threats posed by all types of explosive ordnance, would become the coordination body for mine action in Gaza.
It has secured $5 million of funding but needs a further $40 million to continue its work in Gaza over the next 12 months.
However, "the sector as a whole will need hundreds of millions of US dollars over multiple years in order to make Gaza safe again for the population," Birch added.
A meeting of the main players in these future operations was held two weeks ago in Amman, under the leadership of the United Nations Development Program.
The UNDP is piloting the clearance plan and the participants went through the likely means and methods required when the time comes.
"Because the level of rubble is so unprecedented, it's going to take new thinking on how we proceed with the clearance," said Birch.
UNMAS has said that 65 percent of the buildings destroyed in Gaza were residential, and it would take 100 trucks 14 years to clear the rubble so far.
Birch said clearance operations were still in the planning phase but would require a significant amount of heavy installations.
"The methodology on how we're going to do that – it's still something that's being discussed because of the sheer scale," he said.
Northern Gaza fears
However, a precise assessment of Gaza remains impossible due to the violence of the fighting, bombings and difficulties of access.
"Until we've been able to get access to the north and can conduct an assessment we're not certain about the level of contamination," said Birch.
"Anecdotal stories suggest that it's exceptionally heavy in northern Gaza. Our teams have encountered unexploded ordnance on their missions to the north, and we believe that it will be a huge issue going forward."
The Gaza war started after Hamas's October 7 attack on southern Israel, which resulted in the deaths of 1,170 people, mostly civilians, according to an AFP tally of Israeli official figures.
Israel's retaliatory offensive has killed at least 34,568 people in Gaza, mostly women and children, according to the health ministry in the territory.
