Scientists stress urgent actions
against “rampant” invasive species       

NAIROBI (Xinhua) -- 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.

“As 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 2016.

“This 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.

“We must now shift from adhoc and reactive to proactive mode of fighting the menace of invasive species,” she said.

Kelemu 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.

The scientists are meeting in Nairobi to find new ways of fighting invasive species especially in Africa and Latin America where the problem is rampant.

Mmay-Guri 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 the world.”

“The 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 ICIPE.

Scientists have called for strict regulations before the introduction of animal and plant species in Africa that later turn out to be invasive with negative consequences.

For 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.

The study noted that such species could end up reducing the number of wildlife and hurting tourism in Kenya and Tanzania.

The study was done by scientists from the Centre of Agriculture and Bioscience International, Centre for Invasion Biology at the University of Stellenbosch and the Kenya Wildlife Service.
