Coinciding with its regional consultation with member states in Africa, CABI hosted a policy summit on invasive species in Gaborone, Botswana on 28 February. About 70 delegates representing policymakers, research, the private sector and civil society from across Africa gathered to learn about and discuss the impact of invasives as well as the technical and policy solutions required to defeat them.

CABI scientist Dr Lukas Seehausen has updated delegates at the International Soft Fruit Conference in s-Hertogenbosch, in the Netherlands, on the very latest research in the fight against the devasting fruit fly Drosophila suzukii.

Dr Seehausen, a research scientist in risk analysis and invasion ecology based at CABI’s Swiss centre in Delémont, said a biological control agent – the parasitoid Ganaspis cf. brasiliensis – could soon be released to manage the invasive pest in Europe.

Past, present and future – reflections on the XV International Symposium on Biological Control of Weeds

xv-isbcw-2018.jpgInvasive alien weed species have been a global environmental and human health issue for decades. In 1969, CABI organised the first International Symposium on Biological Control of Weeds (ISBCW) in Delémont, Switzerland. Weed biocontrol research was then in its early stages and 20 scientists attended.

Invasive alien species should not be used in restoring degraded landscapes as their costs outweigh their benefits, experts say.

Invasive alien species, according to the Convention on Biological Diversity, are plants, animals and other organisms that are non-native to an ecosystem, and may adversely affect human health and the environment, including decline or elimination of native species.

Invasive alien plants, land degradation and restoration

Reblogged from Global Landscapes Forum

Invasive alien plants contribute to land degradation by forming vast unproductive monocultures. These invasions have a negative impact on biodiversity, water resources, crop and pasture production, human and animal health, and as such undermine Africa’s ability to achieve its Sustainable Development Goals. Landscapes degraded as a result of unsustainable land-use practices are also more likely to be invaded by invasive plant species, making any attempts at restoration considerably more difficult. As such it is imperative that invasive species management forms an integral part of any attempt at landscape restoration. By actively removing invasive species, followed by restoration, livelihood outcomes will be enhanced across the continent.
