UNITED NATIONS, United States, (AFP) – World powers met Tuesday at the United Nations on how to address rising food insecurity, with dire warnings of a devastating harvest next year due to the war in Ukraine.

The United States joined the European Union, African Union and Spain for a meeting at the ministerial level on food prices, seen as a key factor in conflicts and instability.

US Secretary of State Antony Blinken noted the effects of rising prices in some of the world’s most vulnerable places, including Yemen, which has been devastated by eight years of war from which it is seeing a respite.

“As we’ve seen over the last years as a result of Covid, before that climate change and, more recently, conflict — notably Russia’s aggression against Ukraine — profound food insecurity touches well over 200 million people on this planet, including, of course, in Yemen,” Blinken said.

The United States has increasingly highlighted Russia’s invasion of Ukraine — a major grain producer — as a factor in rising food prices.

Russia has cast blame on Western sanctions over its invasion, an assertion denounced by the United States, which says it is not targeting agricultural or humanitarian goods.

Blinken said it was “vital” to preserve an agreement brokered by the United Nations and Turkey through which ships with grain have been able to sail through the blockaded Black Sea.

But concerns are mounting on the long-term impacts. A recent report by the Ukraine Conflict Observatory, a non-governmental US group, found that around 15 percent of grain stocks in Ukraine have been lost since the invasion in February.

Experts warn that disruptions in fertilizer shipments could seriously impede future harvests around the world.

“It’s very clear that the current food supply disruption and the war in Ukraine is having an impact on the next harvest,” said Alvaro Lario, incoming president of the International Fund for Agricultural Development.

“There’s one or two harvests per year, and already we’re seeing that it’s going to be devastating for next year,” he told AFP, warning that the impact could be “much worse” than Covid.

He called for longer-term action, which would entail billions of dollars of investment, to ensure the stability of food supply chains and to adapt to a warming climate.

“We know the solutions and we have the institutions to make that happen. What is currently lacking is the political will, in terms of the investment,” he said.

In a joint report in July, UN agencies, including UNICEF and the Food and Agriculture Organization, said that between 702 and 828 million people were impacted by hunger in 2021, or 9.8 percent of the world population.
