FAO established an "Emergency Prevention System for Transboundary Animal and Plant Pests and Diseases" in 1994, focusing on the control of diseases like rinderpest, foot-and-mouth disease and avian flu by helping governments coordinate their responses. One key element is the "Global Rinderpest Eradication Programme", which has advanced to a stage where large tracts of Asia and Africa have now been free of the cattle disease rinderpest for an extended period of time. Meanwhile, "Locust Watch" monitors the worldwide locust situation and keeps affected countries and donors informed of expected developments.
