Southern Africa: Armyworm Infestation - Jan 2017Alert
Reports from the Zambia Disaster Management and Mitigation Unit indicate that as of 9 January 2017, close to 130,000 ha planted to maize had been affected by a severe outbreak of the Fall Armyworm, which is new to the southern African region. Of the affected area, over 68,000 ha may require re-planting. Government efforts to control the outbreak are underway...With 94% of the country’s districts affected in varying degrees, including several districts bordering Zambia’s eight neighbours in the SADC region, vigilant region-wide monitoring activities are required.

A fall armyworm outbreak, the first emergence of the pest in southern Africa, is causing considerable crop damage in some countries. If the pest damage aggravates, it could dampen prospects for good crop harvests that is anticipated in the current farming season. Maize, a staple food in the region, has been the most affected, as well as other cereals including sorghum, millet and wheat. Southern Africa is reeling from the effects of two consecutive years of El Niño-induced drought that affected over 40 million people, reduced food availability by 15 percent and caused a cereal deficit of 9 million tonnes.
