Scientists from across the world stressed immediate
measures to stop destructive nature of invasive species
that threatens to reduce food availability and increase
poverty among farmers.
the world makes progress in fighting invasive
species, their threat is growing,” said Dennis
Ragi, director general of Centre for Agriculture
and Biosciences International (CABI) in Kenya.
“Invasive species are now recognized as one of the
biggest threat to human survival,” he told
scientists meeting in Nairobi. Ragi gave the case
of fall armyworm, a worm that has invaded cereals
fields across sub-Sahara Africa since January
has already placed at risk lives of 300 million
people, affected food security and disrupted
peoples’ livelihoods,” he said.
Segenet Kelemu, director general of the
International Centre of Insect Physiology and
Ecology (ICIPE) in Kenya, said time to act is now.
must now shift from adhoc and reactive to
proactive mode of fighting the menace of invasive
species,” she said.
said it is unfortunate that sub-Saharan Africa is
one of the most affected by invasive species,
which is exacerbated by climate change, saying
this calls for urgency in tackling this problem.
scientists are meeting in Nairobi to find new ways
of fighting invasive species especially in Africa
and Latin America where the problem is rampant.

Species in Africa, in Nairobi, capital of Kenya,
Feb. 21, 2018. The objectives of the workshop is
to guide collective action towards bolstering
national capacities to effectively manage
(prevent, eradicate, and/or control) invasive
species, among others.
Saethre, deputy director general of the International
Institute of Tropical Agriculture (IITA), termed
invasive species as “a moving target” for scientists.
“We need to
act fast because this problem is threatening food
security and livelihoods of millions of people across
frequency of invasive species is increasing. It can not
be business as usual in dealing with this problem,” said
Sunday Ekesi, director of research and partnerships at

introduction of animal and plant species in Africa that
later turn out to be invasive with negative
instance, last year a study conducted in Kenya found
that an alien plant species introduced as ornamental
plant in wildlife-rich Serengeti and Mara is now posing
a major threat to plant and animal species there.
noted that such species could end up reducing the number
of wildlife and hurting tourism in Kenya and Tanzania.
