In view of the competing demands of land use to feed the growing pop-ulation, sustain biodiversity, ecosystem services, and mitigate climate change, there is a clear need for a systematic approach for allocating land use with respect to economic and environmental objectives. This study formulates an integrated environmental and economic assessment of the global consequences of changing current land use in the UK with differ-ent land-use strategies for food, feed, fuel, timber, and carbon sink. Life cycle assessment (LCA) is used for the environmental assessment and a parallel economic assessment is integrated with LCA for the character-ization of the main land-use strategies in the UK. The results indicate that changing land use and management on current cropland generally does not deliver improvement in all three criteria of mitigating climate and impacts on ecosystem service and biodiversity, while creating addi-tional economic value. Expanding cropland onto set-aside and perma-nent grassland is more beneficial when crops are used for fuel or for carbon sink. Expansion onto set-aside grassland is largely undesirable if by arable cropping, but desirable by energy and forestry crops. The consequential assessment showed that indirect effects are relevant and ought to be considered when assessing land-use strategies.
