Key modelling activities undertaken were to:
- Parameterise, calibrate and test the ECOSSE (Estimating Carbon in Organic Soils - Sequestration and Emissions) process-based model using field measurements and assess model sensitivities and uncertainty
- Apply the ECOSSE model spatially in the UK to 2050
- Examine spatial patterns of soil carbon stock change and greenhouse gas emissions according to crop type, soil type, management, climate region and climate change
- Develop an Ecosystem Modelling Tool to allow non-specialist users to explore the consequences of land use change arising from bioenergy cropping, in terms of soil carbon and greenhouse gas emissions
Process-based modelling ouptuts
The powerful combination of field-scale measurements and sophisticated modelling has given ELUM the capacity to enhance and validate a range of process models to deliver an Ecosystem Modelling Tool. This high-resolution tool allows users to explore the impact of direct land-use change to bioenergy crops on soil carbon and greenhouse gases down to the 1 km2 level. Users have a number of different ways in which to select the geographical area of interest, add or exclude different land constraints, crop types and then select their chosen time-frame through which to assess the impacts of land-use change.
After rigorous peer review and independent scrutiny, the Ecosystem Land Use model will be made available via the Centre for Ecology & Hydrology website. This model will give policymakers, landowners and commercial bioenergy growers the confidence to evaluate likely impacts of bioenergy land use change through to 2050.
