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…
Why Prosopis no longer ‘pays’ as a prospect for positive environmental and socio-economic productivity

Could invasive plant management prevent the spread of malaria?
CABI scientists have joined an international team of experts who suggest that the large-scale management of a range of some invasive plants could hold the key to reducing the spread of deadly malaria. Dr Arne Witt and Dr Sean Murphy worked with scientists from the University of Illinois, The Ohio State University and the Fundación…
Removal of invasive shrub could be an easy way to help reduce malaria transmission
Removing the flowers of an invasive shrub from mosquito-prone areas might be a simple way to help reduce malaria transmission, according to a new study published in the open access Malaria Journal. Removing the flowers from villages in Mali decreased the local mosquito vector population by nearly 60%.
Use them and lose

A view from Arne Witt, CABI Regional Coordinator, Invasives (Africa & Asia): Promoting the utilization of any invasive non-native species…
