Economic Impact of IAS in the Caribbean: Case Studies (Apr 28, 2015)

CAB International.

To date no studies have been undertaken on the costs and benefits of IAS management in the Caribbean. This may partly explain why there has been negligible funding to combat the onslaught of these exotic species in the region. As a result it was decided to provide individuals involved in the UNEP-GEF Project, "Mitigating the Threats of Invasive Alien Species in the Insular Caribbean" with training and an opportunity to undertake Cost-Benefit Analyses (CBAs) on some selected IAS. The CBAs undertaken and reported in this publication clearly demonstrates that the benefits of managing IAS outweigh the costs.

Government of Canada Releases Socio-Economic Study on the Risk of Grass Carp to the Great Lakes (Mar 13, 2019)

Government of Canada.

Grass carp, one of four species of Asian carp, has the potential to disrupt the Great Lakes ecosystem and economy unless their spread is stopped, according to a report released by Fisheries and Oceans Canada with support from the Great Lakes Fishery Commission and the Ontario Ministry of Natural Resources and Forestry. The socio-economic study concludes that, in addition to the significant ecological threat that is posed by the presence of grass carp in the Great Lakes, there would also be economic, social and cultural ripple effects.

Invasive Mussels Could Cost Montana $234 Million Per Year (Jan 24, 2019) (PDF | 191 KB)

Montana Invasive Species Council.

Montana’s economy could see more than $230 million in annual mitigation costs and lost revenue if invasive mussels become established in the state, according to a report released by the Montana Invasive Species Council (MISC). Commissioned by MISC and completed by the University of Montana Flathead Biological Station, the economic impact study provides “a snapshot of projected direct costs to affected stakeholders dependent on water resources,” said Bryce Christiaens, MISC chair. “It does not reflect the total economic impact to the state, which would be considerably higher.” View a one-page fact sheet (PDF | 484 KB) or the full report (PDF | 4.0 MB).

Invasive Species and Poverty: Exploring the Links (2007) (PDF | 2.24 MB)

Global Invasive Species Programme.

Invasive alien species are more often than not pigeon-holed as an environmental or biodiversity issue, and consequently – especially in developing countries – do not receive due recognition by policy-makers. Yet the reality is that they are a major threat to human livelihoods, especially to agriculture and therefore food security, and are generally undermining human well-being. Moreover, ongoing globalisation and increasing trade are escalating the problem to critical proportions. We hope that this booklet will contribute towards a better understanding of these links and to placing invasive species firmly on the development agenda.

The Economic Cost of Invasive Non-Native Species on Great Britain (2010) (PDF | 1.4 MB)

Great Britain Non-native Species Secretariat; Scottish Government.

The financial cost of non-native species has been published in a new report. "The Economic Cost of Invasive Non-Native Species (INNS) to the British Economy" suggests that invasive species cost 1.7 billion pounds every year. The research was conducted by the international scientific organization CABI for the Scottish Government, Defra and the Welsh Assembly Government and breaks down the effect on each country. It indicates that the economic cost of INNS can be wide ranging and can result in the loss of crops, ecosystems and livelihoods. The cost to the agriculture and horticulture sector alone is estimated to be 1 billion pounds across Britain. See Great Britain Non-native Species Secretariat - Reports for the full report and supporting document.
