Island Conservation.
Restoring islands through the removal of non-native invasive mammals is a powerful biodiversity conservation tool. This new study now shows that human communities on islands could benefit from restoration actions, which can potentially reduce or eliminate the burden of diseases transmitted to people by invasive species. Simply put, removal of invasive species can benefit human health in addition to ecological health.

See in particular Chapter 3: Freshwater, Wetlands, Biodiversity and Human Health, section 5.1 "Aquatic Invasive Alien Species" and Chapter 7: Infectious Diseases, section 2.3.4 "Implications of Biotic Exchange (Invasive Alien Species)".
Caribbean Invasive Alien Species Network.
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.
UNFAO. International Plant Protection Convention.
You cannot protect the environment without also safeguarding plant health. When plant pests and diseases spread into new areas they seriously damage entire ecosystems, putting at risk biological diversity and the environment itself. Tiny and lethal at the same time, plant pests and invasive alien species have been recently identified as the main driver of biodiversity loss. Pests are also responsible for losses of up to USD 220 billion in agricultural trade each year and the loss of 40 percent of the global food crop production. Climate change is making the situation even worse. It is changing the life cycle of pests – sometimes increasing the number of yearly generations - and creating new niches where they can thrive. For more information see the IPPC factsheet "Plant Health and Environmental Protection (PDF | 1.22 MB)".

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. The full report can be viewed here (PDF | 1.34 MB).

Nile perch were introduced to Lake Victoria in the 1950s to boost the fishing industry. The introduction of Nile perch caused an economic boom, but almost caused cichlids, a native fish, to go extinct. Discover the role an invasive species can play in an ecosystem and social system.

A desire to avoid more extinctions is one of the drivers behind new research by the Threatened Species Recovery Hub which has identified invasive species as the no. 1 threat to Australian biodiversity with habitat loss a close second.
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 damage that invasive species can cause to the environment and the economy are well known, but impacts on human health have been much less analysed. However, invasive species can cause impacts ranging from psychological effects, phobias, discomfort and nuisance to allergies, poisoning, bites, disease and even death.

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.
