Highlighting forests’ vulnerability to invasive species

After habitat destruction, invasive alien species are the second biggest threat to biodiversity worldwide. It has a significant impact on livelihoods and the economy, incurring losses of USD$1.4 trillion a year. Prior to 2012 many South-East Asian countries lacked the policies and information on the presence, distribution and impact of invasive species to properly manage this increasingly urgent threat.

The locust invasions devastating Niger

It is the end of December 2016, with clear skies over Niger. But as 2017 draws near prospects are grim for some 500 residents in Bani Kosseye, a village 80km from the capital Niamey. Agricultural production has been poor here, and families’ meagre stocks are expected to run out within a few weeks. People already fear famine. Continue reading

CABI’s ISC datasheets contribute to regulatory action against high-risk freshwater invasive species in the USA

Aquatic invasive species threaten aquatic resources by negatively impacting native organisms and altering ecosystems. They have a competitive advantage over native species because they lack natural enemies to control their spread, they grow and reproduce rapidly, and also adapt to a wide range of environmental conditions.

Invasive alien species (IAS) threaten livelihoods and biodiversity globally

Invasions from non-native plants, animals and pathogens threaten the economies of the world’s poorest nations, according to a new study.

The study, published in Nature Communications (‘Global threats from invasive alien species in the twenty-first century and national response capacities’) found that one-sixth of the world’s land is highly vulnerable to invasion, including substantial areas in developing countries and global biodiversity hotspots.

CABI at EcoSummit 2016

EcoSummit 2a

CABI promoted its new invasive species initiative at this year’s EcoSummit event which took place in Montpellier, France, from 29 August – 1 September. CABI’s latest initiative aims to tackle the issue of invasive species to improve the lives of 50 million farmers in Africa and Asia.

Launched in Copenhagen in 1996, the event provides a platform for ecological scientists and researchers from around the world to share new knowledge and discuss sustainable solutions to global environmental and ecological challenges. This year’s EcoSummit conference focused on terrestrial ecosystems, especially fragile systems that are less resilient to climate change and the impact that human activities are having on the environment – especially agriculture. The increasing global demand for food was also discussed and how intensified agriculture to meet this demand can adversely affect ecosystems.

CABI’s work on invasive species was highly relevant here as many invasive species cause the loss of natural biodiversity and alter global ecosystems. CABI’s expertise in tackling invasive species in order to promote environmental sustainability, livelihoods and food security is a significant contribution to solving global environmental challenges.

Julien Lamontagne-Godwin was one of CABI’s representatives at the conference. He said: “This conference is vital to showcase the myriad avenues of research in ecology, and is a vital tool to describe and remind us of the importance of a healthy ecosystem for our way of life. Many discussions we had with top scientists here highlighted the value of CABI’s knowledge platforms, such as our Invasive Species Compendium. These conversations also helped us add depth and significance to our new livelihoods initiative on invasive species.”

CABI has been working on invasive species for over 100 years, exploring measures to prevent, mitigate and manage invasive species on a global level. Through a selection of different sustainable techniques such as biological control, CABI tackles some of the worst invasive species that negatively impact terrestrial ecosystems and impact the livelihoods of farmers who depend directly on the ecosystem for their sustenance.

New European Union IAS Regulation

Invasive alien species are a major threat worldwide, impacting upon millions of livelihoods and threatening biodiversity. The situation is worsening, due in no small part to increased global trade and transport. The economic costs of IAS can be vast: worldwide, invasive species are estimated to cost US$1.4 trillion per year – close to 5% of global GDP.

In the European Union alone, invasive alien species (IAS) are estimated to cost €12-20 billion a year.

In response to this threat, the European Union adopted Regulation (EU) No 1143/2014 which makes compulsory the management of key IAS that are of concern to the region. Methods include limitation of spread, eradication of early invasions and active management of established IAS. A list of 37 species to be included under the regulation was approved by EU Member States in December 2015 and has recently come into force (Regulation (EU) 2016/1141). It includes 23 animals and 14 plants whose current and potential impacts across the region will mean that collaborative and concerted action is required across the EU.

This is part of the EU’s biodiversity strategy which aims to halt the loss of biodiversity and ecosystem services in the EU by 2020 and is in line with the Convention on Biological Diversity’s (CBD) Aichi Targets, particularly Target 9:

“By 2020, invasive alien species and pathways are identified and prioritized, priority species are controlled or eradicated, and measures are in place to manage pathways to prevent their introduction and establishment.”

At CABI, we have been working on invasive species at a global scale for decades and are experts in their management using both traditional methods and through biological control. This new legislation is welcome; recognising the serious threats that invasive species pose and imposing compulsory measures to lessen the spread and impacts of IAS in the EU.
