Smallholder farmers in eastern and southern Africa are facing a new threat as a plague of intrepid fall armyworms creeps across the region, so far damaging an estimated 287,000 hectares of maize.

Since mid-2016, scientists with the International Maize and Wheat Improvement Center (CIMMYT) and national agricultural research partners have been monitoring reports of sightings of the fall armyworm in Kenya, Tanzania and Uganda. Surveys conducted in 2016 in farmers’ fields confirmed the pest is present in Kenya. The threat of the pest spreading into other eastern Africa countries is a significant risk since the region has similar planting seasons.

Q+A: Scientist Thokozile Ndhlela inspires girls in Africa to embrace agriculture careers

Little did 47-year-old Thokozile Ndhlela know that growing up in a rural area in Zimbabwe would inspire her to become a well-respected agricultural scientist, helping to transform agriculture by developing science-based solutions to some of the complex issues facing African farmers.

Currently a postdoctoral staff member with the International Maize and Wheat Improvement Center (CIMMYT) in Zimbabwe’s capital Harare, Ndhlela encourages girls to choose options that lead to careers in agriculture. Most farmers worldwide average an age of over 60, so Ndhlela’s work is also helping to encourage young people to get involved in agriculture.

Study reveals diversity “blueprint” to help maize crops adapt to changing climates

By Julie Mollins

Scientists have unlocked evolutionary secrets of landraces through an unprecedented study of allelic diversity, revealing more about the genetic basis of flowering time and how maize adapts to variable environments, according to new research published in Nature Genetics journal. The discovery opens up opportunities to explore and use landrace diversity in new ways to help breeders adapt crops to climate change and other emerging challenges to crop production.

New cycle of maize lethal necrosis germplasm screening to begin at Kenya site in May 2017

The first screening activity for the 2017A planting cycle from March to May is set to begin in May 2017 at the joint Kenya Agricultural and Livestock Research Organization (KALRO)–International Maize and Wheat Improvement Center (CIMMYT) maize lethal necrosis (MLN) artificial inoculation screening site at Naivasha, Kenya.

Deadline for interested private and public sector organizations to send their maize germplasm for screening is March 30, 2017 to enable processing imports and clear seed shipment that takes between six to eight weeks. Planting is due to start at the first week of May 2017.

Since its establishment in 2013 as a response to the MLN outbreak, the screening facility has so far screened over 60,000 entries from 16 private and public institutions including seed companies and national research organizations in Africa and beyond. The facility was established with support from the Bill & Melinda Gates Foundation and the Syngenta Foundation for Sustainable Agriculture.
