Africa
is the world’s largest producer of cassava, accounting for 57%of a crop that
some 800 million people around the world rely on.
The
plant's starchy, tuberous root is the third largest source of carbohydrates in
tropical countries and a vital food for many subsistence farmers.
But
a new disease, the brown streak virus, has spread in recent years, causing
90-100% losses in some infected crops, with researchers from 12 African
countries calling for urgent action to avoid a looming "food
disaster" for the continent.
"We
call on governments to put in place an early warning system, a response
strategy to this disease," Justin Pita, executive director of the West
African Virus Epidemiology (WAVE) programme, said.
Corneille
Ahanhanzo, a researcher in Benin, said not enough time, money and research was
being committed to stop the disease's spread.
"It's
time for us researchers to stand up against this disease that will be an 'Ebola
for plants'," he told AFP.
First
documented in East Africa, scientists have watched outbreaks of brown streak
virus spread into parts of Central Africa, with fears it could push further
west.
In
Nigeria alone, Africa's most populous nation, cassava is a regular source of
carbohydrate for 80% of the country's 180 million inhabitants.
