The boss of one of the world's biggest fertilizer companies has said the war in Ukraine will deliver a shock to the global supply and cost of food. Yara International, which operates in more than 60 countries, buys considerable amounts of essential raw materials from Russia. Fertilizer prices were already high due to soaring wholesale gas prices. Yara's boss, Svein Tore Holsether, has warned the situation could get even tougher. "Things are changing by the hour," he told the BBC. "We were already in a difficult situation before the war... and now it's additional disruption to the supply chains and we're getting close to the most important part of this season for the Northern hemisphere, where a lot of fertilizer needs to move on and that will quite likely be impacted." Russia and Ukraine are some of the biggest producers in agriculture and food globally. Russia also produces enormous amounts of nutrients, like potash and phosphate - key ingredients in fertilizers, which enable plants and crops to grow. "Half the world's population gets food as a result of fertilizers... and if that's removed from the field for some crops, [the yield] will drop by 50%," Holsether said. "For me, it's not whether we are moving into a global food crisis - it's how large the crisis will be." His company has already been affected by the conflict after a missile hit Yara's office in Kyiv. The 11 staff were unharmed. The Norwegian-based company isn't directly affected by sanctions against Russia, but is having to deal with the fall-out. Trying to secure deliveries has become more difficult due to disruption in the shipping industry. Just hours after Holsether spoke to the BBC, the Russian government urged its producers to halt fertilizer exports. He pointed out that about a quarter of the key nutrients used in European food production come from Russia. "At the same time we're doing whatever we can do at the moment to also find additional sources. But with such short timelines it's limited," he said before the news emerged. Analysts have also warned that the move would mean higher costs for farmers and lower crop yields. That could feed through into even higher costs for food. Nutrients aren't the only factor to consider, either. Huge amounts of natural gas are needed to produce ammonia, the key ingredient in nitrogen fertilizer. Yara International relies on vast quantities of Russian gas for its European plants. Last year, it was forced to temporarily suspend production of about 40% of its capacity in Europe because of the spike in the price of wholesale gas. Other producers also cut supplies. Combined with higher shipping rates, sanctions on Belarus (another major potash supplier) and extreme weather - this prompted a big jump in fertilizer prices last year, adding to a surge in food prices. The company says it's making day-to-day evaluations on how to maintain supply and that it is too early to say if more shutdowns may be on the cards. It acknowledges it has a "very strong obligation" to keep production running at what it describes as a critical point. But Yara's boss says the world must, in the long-term, reduce its dependency on Russia for global food production. "On the one hand, we're trying to keep fertilizer flowing to the farmers to keep up the agricultural yields. "At the same time... there has to be a strong reaction. We condemn the Russian military invasion of Ukraine so this is a dilemma and one that frankly is very difficult." Climate change and growing populations had already been adding to the challenges the global food production system faces - all before the pandemic started. The Yara International chief executive describes the war as "a catastrophe on top of a catastrophe", highlighting just how vulnerable to shocks the global food supply chain now is. It will increase food insecurity in poorer countries, he adds. "We have to keep in mind that in the last two years, there's been an increase of 500 million more people that go to bed hungry... so for this to come on top of it is really worrying." — BBC
