ANTALYA, Turkiye: Iran and the United States should “immediately” allow fertilizer shipments through the Strait of Hormuz to ease the crisis in some of the most vulnerable countries, a senior UN official said Saturday.

Jorge Moreira da Silva, head of the UN Office for Project Services, told the COP31 climate talks in the Turkish resort city of Antalya that the lack of fertilizers could push millions into poverty.

The Iranian blockade of the vital waterway, which started after the joint US-Israeli attack against Iran in late February, has choked shipping in the region and beyond. The US blockade of Iranian ports has further complicated matters.

While Iran and the United States are still trying to negotiate an end to the conflict, Moreira da Silva said he had the same message for both countries.

“They should continue their negotiations about the comprehensive deal — but that deal should not avoid an immediate, exceptional, limited, and time-bound solution for the fertilizers,” he said.

“Basically what we need is five vessels a day with fertilizers,” he added.

- Millions at risk -

Moreira da Silva heads up the UN task force dedicated to facilitating the safe passage of fertilizers during the crisis.

Before the conflict, a third of the world’s fertilizers passed through the Strait of Hormuz, and since the blockades, their prices had risen by 30 percent, he said.

“But what I think is not sufficiently recognized is the disproportionate impact on the most vulnerable countries,” he added.

Sudan’s finance minister recently told him that the price of food there had doubled in six months, he added. In Nepal, they had told him that farmers could no longer afford to buy fertilizers.

“So it’s very important that we are aware that countries such as Mozambique, Kenya, Sudan, Somalia, Nepal, Bangladesh, Sri Lanka are facing very significant impact.”

The effects of this shortage could be catastrophic, he warned.

“If we continue missing the planting seasons in different parts of the world we may have 45 million people facing severe and acute food insecurity,” he said.

“We may have 30 million people being forced into poverty.”

The UN had a system ready to get fertilizer shipments moving within seven to 10 days, he said.
