Geografische Informatie Agrarische Bedrijven 2019 : documentatie van het GIAB 2019 bestand

Os, J. van; Kros, J.


To compile the national emissions inventory, the National Institute for Public Health and the Environment (RIVM) has to have an accurate picture of the locations of all the livestock farms in the Netherlands. The GIAB-plus dataset (Geographical Information on Agricultural Businesses) was created for this purpose in 2009. In this dataset, animal numbers taken from the agricultural census are reallocated across the farm locations obtained from the animal registers and associated with the types of livestock housing recorded in the agricultural census. Since 2015 the livestock housing census have been made available as a supplement. These record for each location the average number of animals, divided into animal group, each agricultural business held and in which types of housing, per calendar year. Since emission year 2016 this additional information has been used as the basis for the GIAB dataset and the information from the agricultural census and animal registers is used as an aid to check these records and where necessary improve the data they contain. This report describes how the GIAB 2019 was compiled and what it can be used for. Besides localising emissions from livestock farming, the dataset can be used in regional studies of the agricultural structure and for research into the spread of animal diseases.
