Global warming will lift agriculture weed threat

Tumble mustard Invasive weeds pose a significant threat to global agriculture productivity – and their threat will become more pronounced if the earth’s climate is affected by increased greenhouse gas concentration, according to a Flinders University climate researcher. Working with computer models to predict the likely impact of climate change on invasive weed propagation, Dr. Farzin Shabani from Flinders University’s Global Ecology Lab found a likely increase in areas of habitat suitability for the majority of IWS (invasive weed species) in European countries, parts of the US and Australia, posing a great potential danger to global biodiversity. In predicting the impact of climate change on current and future global distributions of invasive weed species, Dr. Shabani also found that existing attempts to eradicate invasive populations are inadequate. Dr. Shabani and an international team of researchers investigated 32 globally important Invasive Weed Species to assess whether c
