Temporal land use patterns and livestock numbers across several river catchments. Within DAFM the Land Parcel Identification System (LPIS) division generated a list of herds who had land in each river catchment area for a select number of river catchments from 2014-2020. The departments Animal Identification & Movement (AIM) division provided the bovine and ovine figures for each herd in each year.
It should be noted that the AIM data was generated for herds who had land in each river catchment area. It is likely that some herds also had land outside the river catchment areas. In total AIM were supplied with 26,002 herds to report on across each location and year. 2,198 of these herds were not included in the final dataset because they either did not have cattle in the period, or did not have sheep census returns in the period (or both).
This dataset is interesting as it is published by Catchment (not County or ED), which makes it useful for water quality purposes. So I asked the Open Data Officer in DAFM why this is the case. Response is as follows:
We received a specific request looking for land use patterns and livestock numbers across several river catchments and how these may have changed over time as part of the Climate Change Mitigation Research Programme | CCMRP | Inland Fisheries Ireland project. As part of the request, we were provided a shapefile by the requester for each river catchment area they required data for. LPIS generated lists of herds who had land in each river catchment area for each year. AIM provided the bovine and ovine figures for each herd in each year.
