Presentation given at the 12th International IPM Symposium (Memphis, TN USA on 27-29 March 2012) by Keith Cressman.
FAO operates an early warning system to keep the international donor community and some 30 affected countries informed of the Desert Locust situation and potential developments concerning breeding and migration. The system is the basis of the preventive control strategy to reduce plagues. Remote sensing products are used operationally to help detect rainfall and green vegetation in locust habitats and to guide survey teams. Custom GIS applications are utilized in affected countries and at FAO for data analysis. An overview of these technologies, including lessons learned during the past two decades, is presented.
