Can drought-resilient maize take pressure off African farmers?

Is drought-resilient maize an answer to pressure on African farmers through climate change? The Center for Development Research (ZEF) organised a panel of experts to address this topic in Bonn, Germany.

Maize is an important staple food crop in most of sub-Saharan Africa, and it is grown on around 33 million of the total 194 million hectares under cultivation in the region. However, El Niño and global warming have had a dramatic effect on farming in many areas. The 2015-2016 El Niño event was one of the strongest on record. Among the countries affected in Africa was Ethiopia, which saw its worst drought in decades. The country, which is the continent’s fifth-largest maize producer, suffered huge crop losses, and an estimated 1.35 million farmers were left without new seed.

As temperatures soar, Zimbabwe’s farmers test maize that can cope

Apolonia Marutsvaka looks triumphant as she shows off one of her three bags of gleaming white maize. She harvested the grain in the midst of a drought and sapping heat that charred many other types of crop.

The secret of her successful harvest is simple: A type of maize seed that has been bred to tolerate high temperatures.

“It has never been this hot, but (this) variety of maize performs well in the heat,” said the 62-year-old Marutsvaka. “I am preparing my maize field to plant it again.”

Marutsvaka is hopeful the new variety will continue to ensure her a harvest even as temperatures soar above 30 degrees Celsius here in Masvingo Province and across Zimbabwe.

Drought-tolerant maize a boon to farmers in Zambia hit by El Niño

“With consistently impressive harvests thanks to DT maize varieties, I’m always assured that my family will have enough food, and I can earn a decent income from selling some grain,” said Piri, a smallholder farmer in Petauke District, Zambia. Photo: CIMMYT/Rodney Lunduka.

Drought-related challenges in Africa call for proactive interventions rather than reactive ones. Every so often a drought hits, jolting the development community into action, and leading to the delivery of food aid to millions of people facing starvation — beneficial efforts in the short term, but futile for achieving lasting change.

Action needed to adapt maize breeding to climate change, report shows

Breeding and seed systems must be adapted to survive projected climate change if major loss of maize yields is to be avoided, a new report shows.

Tools that forecast the response of crops to different weather and climate conditions, coupled with crop yield modeling have enabled agricultural scientists to predict and formulate plans for potential future climate change.
