Locust Watch


Over the years, FAO has carried out various activities in desert locust early warning and prevention. The Locust Watch provides information on the activities aimed at strengthening the national and regional capacities of the affected countries to monitor, prevent, and manage the Desert Locust.

This is useful in understanding the locust behavior, environmental conditions that can influence locust life cycles, and tested and proven locust control and management practices used in different regions as well as adopting innovative approaches in monitoring and controlling desert locust.

A dynamic map that shows where vegetation is present in the desert and how long it has been green to better monitor Desert Locusts habitats


FAO's Desert Locust Information Service (DLIS) is engaged with three dozen academic, research, and private sector partners to continually innovate and harness the latest cutting-edge technologies for improving Desert Locust early warning. The goal is to provide more accurate advice and guidance earlier while streamlining procedures and simplifying messaging. A number of new technologies have been integrated into DLIS and the national locust programmes.
