CABI scientists have revealed the massive ecological and economic impacts that the invasive alien tree Prosopis juliflora has had across the Afar Region of north eastern Ethiopia.
Dr Urs Schaffner, who is supervising lead author Mr Hailu Shiferaw for his PhD studies, contributed to the Science of The Total Environment published research which shows that the devastating Prosopis was a major reason for losses in annual ecosystem service values in Afar Region estimated at US $602 million in just 31 years.
CABI has led an international team of Non-Native Species (NNS) specialists who have compiled a list of recommendations to improve the way in which the impact of a range of invasive pests – such as the tomato leaf miner Tuta absoluta – are assessed, potentially helping towards ensuring greater global food security.
Farmers and authorities throughout Asia need to be vigilant against fall armyworm invasions, after confirmation that the fast-moving pest has spread from India to China and now to South-East Asia, agricultural experts say.
A project aimed at managing the risks and costs of invasive alien species on important ecosystems, species and genetic diversity was launched in St. Kitts and Nevis on Tuesday, at the Ocean Terrace Inn Conference Room.
Warmer temperatures increase the metabolism and reproductive rates of the pest
Fall Armyworm was first reported in July 2018 in Karnataka. Ever since, it has spread to its neighbouring states. Reports are now coming from West Bengal and Bihar as well. The initial damages are widespread as the pest is a voracious feeder. But we have reacted quickly. The Karnataka government, for example, has issued ad hoc recommendations for emergency response against it.
CABI scientists have helped map the ferocious speed and probable cause of a devastating spread of the invasive alien tree Prosopis juliflora (Swartz DC) across an area equivalent to half of neighbouring Djibouti in the Afar Region of north eastern Ethiopia.
