The FAO has three categories of Desert Locust situations: outbreak, upsurge, and plague. The current locust attack (2019-2020) has been categorised as an upsurge

India should remain on high alert against locust attack for the next four weeks, the Food and Agriculture Organization (FAO) has warned amid the country facing the worst locust attack in 26 years.

In its latest update on Friday, the FAO said spring-bred locust swarms, which migrated to the Indo-Pakistan border and travelled east to northern states, are expected to return back to Rajasthan with the start of the monsoon in coming days. The FAO has three categories of Desert Locust situations: outbreak, upsurge, and plague. The current locust attack (2019-2020) has been categorised as an upsurge. Outbreaks are common, but only a few result in upsurges. Similarly, few upsurges lead to plagues. The last major plague was in 1987-89 and the last major upsurge was in 2003-05. Upsurges and plagues do not occur overnight; instead, they take many months to develop.
