UK soil database for modelling soil carbon fluxes and land use for the national carbon dioxide inventory - SP0511

Description
Under the Kyoto Protocol, the UK is required to make estimates of net carbon emissions to the atmosphere. One potential source is the soil. An important driver of either soil carbon loss or gain is land use change. The size of the net carbon emission from soil is currently determined from various algorithms but relatively little use has been made of process-based numerical models of soil carbon turnover. The Department of Soil Science, IACR-Rothamsted is currently undertaking a project funded by MAFF to carry out just such modelling. To yield the greatest benefit the models will require input from a harmonised soil and land use database for the whole of the UK.

Experience to date has been that UK regions hold different soil carbon databases because of differences in soil classification systems, methods of analysis and definitions of critical soil properties. This has led to time-consuming and expensive re-runs of the databases each time a project relating to soil carbon arises. A standardised UK soil carbon database is needed with output that is compatible with GIS and numerical modelling requirements.
Objective
1. To assess the scientific quality and consistency of the soil type/land use database currently used as the basis for UK greenhouse gas inventory estimates of carbon dioxide emissions from land use and land use change
2. To construct a soil type/land use database for England and Wales, which includes all relevant parameters for soil carbon turnover modelling
3. To construct similar databases for Scotland and Northern Ireland
4. To join these databases into a seamless whole using transparent methodology, which uses a common system of geo-referencing and file formats compatible with the chosen carbon turnover model
5. To contribute to the development and use of this database in relation to the modelling
6. To assist in the interpretation of modelled outputs with measured data drawn from the National Soil Inventory of England and Wales and the core databases for Scotland and Northern Ireland.
7. To place the final dataset within SSLRC¡¦s land information system (LandIS).
