The 'bioenergy boom' of recent years has polarised opinion: while supporters claim that bioenergy can help to secure energy supply, mitigate climate change and create development opportunities, its critics maintain that the production of bioenergy crops will heighten land use conflicts as food cultivation, nature conservation and bioenergy production compete for land.In Future Bioenergy and Sustainable Land Use, WBGU's central message is that use should be made of the sustainable potential of bioenergy, which can be tapped all over the world, provided that risks to sustainability are excluded. However, this aim will require considerable international co-operation and co-ordination to ensure that the use of bioenergy does not endanger food security or the goals of nature conservation and climate change mitigation.The report thus presents an integrated vision that will provide policy-makers with clear guidance for the deployment of bioenergy.
