Global threats from invasive alien species in the twenty-first century and national response capacities

Posted on Wed, 24 Aug 2016, 11:26

Invasive alien species (IAS) threaten human livelihoods and biodiversity globally. Increasing globalization facilitates IAS arrival, and environmental changes, including climate change, facilitate IAS establishment. Here we provide the first global, spatial analysis of the terrestrial threat from IAS in light of twenty-first century globalization and environmental change, and evaluate national capacities to prevent and manage species invasions. We find that one-sixth of the global land surface is highly vulnerable to invasion, including substantial areas in developing economies and biodiversity hotspots. The dominant invasion vectors differ between high-income countries (imports, particularly of plants and pets) and low-income countries (air travel). Uniting ...

Scientists gear up to battle invasive species

Posted on Wed, 24 Aug 2016, 08:34

A research programme to tackle invasive species that kill plants and sicken animals is getting under way at the United Kingdom’s Centre for Agriculture and Bioscience International (CABI). The programme, worth US$50 million, aims to find scientific solution that help farmers to either defeat or adapt to the presence of invasive species. The goal is to tackle the devastating economic impact of such species, estimated to be around $183 billion in lost crops and revenue in Sub-Saharan Africa, South Asia and South-East Asia every year.

Threats from Invasive Species: A driver for the extinction of plants

Posted on Tue, 10 May 2016, 18:04

A fifth of the world's plant species are at risk of extinction, British researchers warned Tuesday in an unprecedented global census of the plant kingdom. The survey by Britain's Royal Botanic Gardens at Kew, London, said 21 percent of plant species are under threat. The report, the first of its kind, is intended to become a global reference point for the study of plants.

The study, which estimates there are a total of 390,900 plants known to science, found farming to be the biggest extinction threat. Logging, the gathering of plants, construction work, climate change and severe ...
