Land use changes can result in emissions and removals from the atmosphere of the most important greenhouse gas, carbon dioxide (CO2), thus influencing potential climatic change. In this study, annual agricultural census data is used to estimate the net flux from land use change on UK agricultural land, which comprises over three quarters of the UK land area. The assessment includes a new estimate of changes in carbon storage on arable land due to improvements in yield and changes in area devoted to different crops. The study complements recent assessments of CO2 flux in the forestry sector, and provides an alternative to a previous assessment of CO2 flux in the agricultural sector based on periodic land cover surveys. In this study the authors estimate changes in CO2 emissions and storage from above-ground biomass on agricultural land for the period 1970-1992. Annual CO2-C flux on agricultural land is estimated as 200 to 417 kC per year in the period 1970-1988 and 339 to 371 kC per year during 1988-1992. These results are consistent with the estimated range for 1990 published in the UK national communication to the Framework Convention on Climate Change, but may provide a preferable point estimate for the agricultural sector. The intervals used in this study were selected in order to identify flux changes resulting from important new UK land use policy: the introduction in 1988 of incentives to take arable land out of production, known as set-aside. To date, the set-aside programme has resulted in very little carbon sequestration. However such a policy could result in much greater carbon sequestration in future, as the rotation requirement for such land use has been waived from 1996 onwards
