FAO Alert: Desert Locusts Threaten Iran Crops

Iran has been placed by the Food and Agriculture Organization of the United Nations in the group of countries where crops face the threat of desert locusts. 
This means that the country should remain vigilant and seriously conduct field surveys and control operations.
Other countries placed in the same category are Sudan and Saudi Arabia.
To keep the world informed of the seriousness of the current locust situation, the Locust Group uses a color-coded scheme; green for “calm”, yellow for “caution”, orange for “threat” and red for “danger”, FAO writes on its website.
