After habitat destruction, invasive alien species are the second biggest threat to biodiversity worldwide. It has a significant impact on livelihoods and the economy, incurring losses of USD$1.4 trillion a year. Prior to 2012 many South-East Asian countries lacked the policies and information on the presence, distribution and impact of invasive species to properly manage this increasingly urgent threat.

It is the end of December 2016, with clear skies over Niger. But as 2017 draws near prospects are grim for some 500 residents in Bani Kosseye, a village 80km from the capital Niamey. Agricultural production has been poor here, and families’ meagre stocks are expected to run out within a few weeks. People already fear famine. Continue reading
The fall armyworm, Spodoptera frugiperda, is making headlines worldwide for all the wrong reasons. The caterpillar crop pest, native to the Americas, was reported in Africa for the first time last year and is now rapidly marching across the continent. It is a voracious pest of maize and other staple crops and has already destroyed tens of thousands of hectares of farmland. As such, it risks devastating smallholder livelihoods throughout Africa. Given that CABI scientists predict it could reach Europe and Asia in a matter of years, it looks set to quickly become a global problem.
The case for action against fall armyworm is overwhelming. On the ground, CABI will support national extension services to help farmers identify the pest quickly and accurately, contribute to awareness-raising and conduct studies to work out the best ways to control it that are not overly dependent on insecticides. Alongside these efforts, CABI also has a range of freely-available materials to help people understand and manage fall armyworm. Continue reading
In this video, scientists and local people explain the dangers of Opuntia stricta, an invasive cactus weed covering large tracts of land in Kenya’s semi-arid Laikipia County, and efforts in place to tame its spread and adverse impacts. Continue reading
CABI has produced a new video which focuses on how we are using biological control, or biocontrol, to manage some of the worst invasive species that are affecting farmers’ livelihoods.
The Global Forum on Agricultural Research (GFAR) posted four blogs about CABI’s activities in its ‘Partner Spotlight’ feature. One of these was on a four-year Global Environment Facility (GEF) funded project that we led which ended recently. The FORIS project was about preserving important genetic diversity in some of SE Asia’s forests. The blog is re-posted here.
The Global Forum on Agricultural Research (GFAR) has blogged about CABI’s activities in its ‘Partner Spotlight’ feature (12-15). One of these was our new invasive species programme which is re-posted here.
Millions of people living in rural communities around the world face problems with invasive species –animals, diseases, insects and plants – that are out of control and have resulted in damage costing more than an estimated US $1.4 trillion globally (Pimentel et al 2001). Yet, while we may have heard about the threats of losing biodiversity, some may have never considered how the addition of a species could be a detriment to agriculture and farmers. Continue reading
