Climate change effects on land use and ecosystems: Belgian case study

The Belgium case study is a nested database of information at 2 spatial levels: Belgium (as a country) and the Dyle Catchement (catchment of 670km² in Central Belgium). The GIS database consists of vector shapefiles as well as raster layers. At the geographic extent of Belgium, agricultural census data are available at NUTS5, yield data for "circonscription agricoles", DTM at 1000m resolution, species distributions at 8x10km² grid, "Aardewerk" point profiles and soil association map, road and river networks, land use from CORINE and Pelcom.

Data collected for the Dyle Catchement are: IACS parcel data (shapefile of declared agricultural parcels) for 1999, farm locations (918 farms), land use derived from LandsatTM 1999 image, aerial photography from 2000, scanned topographic maps 1:10000 from 1980, DTM at 30m resolution, detailed precipitation data.

The Accelerates model, based on a Ricardian approach, produces acceptable results at country scale. Statistical analysis of the Dyle data showed that at the local level, different factors (topography, distance to farm, farm location, farm typology, neighbourhood interactions) determine agricultural practices, land use and landscape structure.

A simple agent-based model showed that competition between farmers is partly responsible for the relative parcel distribution in space (relative to the farm).

Aggregation experiments in the Dyle unravelled the very low accuracy of Corine and Pelcom land use datasets, compared to the IACS data.
