Reliable data is the basis for trend analysis and policy advice. The Thünen Institute collects most of this data: in our own monitoring programs and with cooperating partners. We also draw upon other data, such as agricultural structural surveys, agricultural statistics, and geo-referenced land use data.
One problem we often face is, however, that at the large-scale, for example the community level, access to data is restricted. This is why the Thünen Institute developed an estimation method combined with a comprehensive data collection on the basis of which trends in land use and animal husbandry can be described up to the community level. The results of the project “Agricultural Atlas” are illustrated in three map collections on agricultural usage.
Four further map collections provide insight in the various topics of forestry monitoring and research. The maps on wood supplies and carbon storage in German forests are based on monitoring programs carried out in cooperation with the federal states.
As in the case of climatic water balances, these maps are provided on the level of “growing areas”. Growing areas are rural spaces with comparably good growth conditions; particularly valuable for spatial presentations of forest growth as well as material and water flows in forests. The maps for the hunting routes are, in contrast, done at the county level and include all hunting areas including forest, open land, and water bodies.
