The ELUM project was commissioned to improve understanding on the GHG and soil carbon changes arising as a result of direct land-use change to bioenergy crops, with a focus on the second-generation bioenergy crops Miscanthus, short rotation coppice willow and short rotation forestry.The project was UK-bound, but with many outcomes which could be internationally relevant. Indirect land-use change impacts were out of scope. This deliverable presents a review of existing (2012) models, toolkits and resources available to assess the effects of a land use change to bioenergy crops from specified transitions. This report reviews the current (as of 2012) global literature covering the technological aspects of Work Package WP2 (chronosequencing approach to monitoring soil organic carbon), WP3 (dynamic approach to measuring soil carbon and atmospheric GHG emissions) and WP4 (numerical modellingapproaches), specific to bioenergy land use transitions.The findings of this review were designed to further inform the design of the ETI’s ELUM project experimental and modelling work from within the global scientific community. It was to provide key recommendations and help to guide the consortium as it delivered the ELUM project, and maintain cutting edge empirical and modelling work relevant to the development of sustainable bioenergy land-use transitions.
