Many countries are currently looking at growing high-yielding crops for the production of biofuels as alternatives to traditional fuels (petrol and diesel) to address imminent energy shortages and reduce impacts of climate change. This usually involves the importation of foreign (i.e., alien) species of plants that are known for their fast and productive growth.

Many governments are actively encouraging private investment in biofuels developments to harness the perceived benefits of biofuels such as agricultural development, increased energy security and independence, improved balance of trade and reduced greenhouse gas emissions. However, in the rush to pursue the benefits of biofuels, the risks of invasion by introduced species have received little or no attention and are not being adequately prevented or managed. The situation is most acute in countries lacking the capacity and resources to adequately avoid and manage the risks of invasion.
