Economic evaluation of biological invasions-a survey. Nonetheless, our findings call for the implementation of consistent management actions and international policy agreements that aim to reduce the burden of invasive alien species.īorn, W., Rauschmayer, F. Research approaches that document the costs of biological invasions need to be further improved. We show that the documented costs are widely distributed and have strong gaps at regional and taxonomic scales, with damage costs being an order of magnitude higher than management expenditures.
These costs remain strongly underestimated and do not show any sign of slowing down, exhibiting a consistent threefold increase per decade. Moreover, we estimate that the annual mean cost could reach US$162.7 billion in 2017. Here we found that the total reported costs of invasions reached a minimum of US$1.288 trillion (2017 US dollars) over the past few decades (1970–2017), with an annual mean cost of US$26.8 billion. The InvaCost database has enabled the generation of a reliable, comprehensive, standardized and easily updatable synthesis of the monetary costs of biological invasions worldwide 3. Biological invasions are responsible for substantial biodiversity declines as well as high economic losses to society and monetary expenditures associated with the management of these invasions 1, 2.
