The United Nations has warned again that the world is on the brink of its worst food crisis in at least 50 years.

Recently, the United Nations released a report, once again for countries to sound the alarm. According to the U.S. Department of Agriculture, about 11 percent of U.S. households are already “food insecure” in 2018. In some U.S. states, nearly half of respondents reported that the new corona pneumonia pandemic threatened food safety, according to a new U.S. study.

The spread of the new crown pneumonia outbreak has also put enormous pressure on the global food supply chain. Some food-exporting countries have introduced policies to restrict or even ban food exports in order to protect themselves. Vietnam was the first to announce a halt to rice exports; india, a rice exporter, has stalled because of its “sealing” and wheat exporter Russia has subsequently restricted sales. In addition, severe locust plagues are threatening some countries in Africa and South Asia. Some Indian scholars predict that the locust plague may reduce food production by 30-50 per cent. For Pakistan, already struggling with food insecurity, the locust plague is even more deadly.

A report by the Food and Agriculture Organization of the United Nations, the International Fund for Agricultural Development, the World Food Programme and others suggests that the outbreak could lead to a significant increase in the number of hungry people worldwide by 2020. This year, 130 million hungry people will be added, and 690 million people worldwide will be hungry. A United Nations study warns that 25 countries are at risk of severe hunger this year and that the world is on the brink of its worst food crisis in at least 50 years.
