The UN Food Agency said on Monday that world hunger is rising again after staying neutral for years, and millions are suffering from the effects of climate extremes and conflict combined.

Jose Graziano da Silva, director-general of the U.N. Food and Agriculture Organization (FAO) said, “Preliminary data available for this year indicates that the number of undernourished people in the world has (started to) rise again.” “Unfortunately this is not good news,” he added. Although he couldn’t come up with any exact figure but assured that the data will be available in September.

According to the FAO, the number of people starving had decreased to 795 million in 2014-16, down 21 percent on 1990–92.

But Graziano da Silva said that the setback in this year’s fight against hunger came as no surprise. In Nigeria, Somalia, Yemen and South Sudan, almost 20 million people are already starving because of fighting and drought.

Total 19 nations are facing a protraction of crises, where conflicts and violence often add up to the natural climate shocks such as droughts and floods caused by a warming planet. “About 60 percent of the people suffering from hunger in the world live in areas affected by conflict and the impact of climate change,” he said.

One of the UN’s Sustainable Development Goals adopted by member states in 2015 is to achieve zero hunger by 2030. But now the goal has “zero chance of succeeding in the atmosphere that we have in the world today”, due to conflicts, according to David Beasley, head of the U.N. World Food Programme (WFP). 10 of the 13 countires that the WFP spent the most money on faced a shortage of food due to man-made reasons. But there is still hope. “Maybe we should slow down and back up a little and focus just on two or three big conflicts,” he said. He thinks that would free enough resources to lower down the intensity of food shortages, if not eradicate hunger.

Nominated for the role of WFP executive director by the administration of US President Donald Trump, Beaseley said that the United Nations will continue with its humanitarian funding and requested the governments to come forward. “I have no doubt that the United States will not turn its back. It will stand strong,” he said.
