Using GIS and remote sensing in the IPM context of early warning

1,024 views

Published on

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.

  6. 6. front-line secondary invasion warning level: CAUTION DESERT LOCUST BULLETIN FAO Emergency Centre for Locust Operations No. 401 General Situation during February 2012 (2 Mar 2012) Forecast until mid-April 2012 A Desert Locust outbreak developed in early near Djanet. National ground teams treated 2,365 February in southwest Libya. Some adults moved ha in Libya and 230 ha in Algeria during February. into adjacent areas of southeast Algeria where Good rains fell over a large area at mid-month and local infestations were already present. Survey high-density adult groups were seen copulating. and control operations were limited due to Consequently, a second generation of breeding will insecurity in both areas. Good rains that fell in occur with hatching and hopper band formation during both countries will allow a second generation of March and April. This is expected to cause locust breeding to occur during March and April. This numbers to increase dramatically in Libya and, to a is expected to cause locust numbers to increase lesser extent, in Algeria. The situation is not entirely dramatically and hopper bands to form. Scattered adults arriving from northern Niger may augment on both sides of the border that hamper survey and local populations. All efforts are required to control operations. In northern Niger, scattered adults monitor the situation carefully and undertake the that are likely to be present in the Air Mountains may necessary control operations to avoid a further move into southern Algeria during March. No locusts escalation in the situation. Elsewhere, there was were reported elsewhere in the region. very little locust activity in the winter breedingdata collection • analysis • inform areas along both sides of the Red Sea due to Central Region.

In South-West in the winter breeding areas along both sides of www.fao.org/ag/locusts Asia, small-scale breeding is expected to occur the Red Sea due to a lack of rain during February. during the forecast period in western Pakistan and Nevertheless, breeding conditions were favourable on southeastern Iran but locust numbers will remain the southern coast in Sudan where scattered adults below threatening levels. were present and laying eggs, and on the central Red Sea coast in Yemen. Isolated adults were present in Western Region. An outbreak developed in early northern Oman. No locusts were seen during surveys February in southwest Libya near the Algerian in Egypt and Saudi Arabia.
