Homogeneous zone according to agro-climatic criteria that condition grassland production in Auvergne

Homogeneous area according to agro-climatic criteria that condition grassland production. This zoning was based on the results of the “prairies” survey carried out by the SCEES in 1982. It was determined on the basis of the following criteria: — climate (especially humidity) — average altitude — geology (nature of soil and subsoil) They were revised in 1998 to work on areas of at least 90,000 hectares. They serve as the basis for the Prairie Objective Information and Monitoring (ISOP) system, which provides estimates of the yields of both temporary and permanent productive grasslands. The 228 French feed regions exclude the low-forage departments: L'island of France and the Mediterranean. __Origin__ Location at l' address Data from the departmental platform (Observatoire 41) __Partner organisations__ DDT Cantal __Links annexes__ * [XML metadata view](http://ogc.geo-ide.developpement-durable.gouv.fr/csw/all-dataset?REQUEST=GetRecordById&SERVICE=CSW&VERSION=2.0.2&RESULTTYPE=results&elementSetName=full&TYPENAMES=gmd:MD_Metadata&OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&ID=fr-120066022-jdd-72cf8a27-75e5-4b5e-9131-e1d721a9fdb9) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/2b791e1635ff182fad6aa563ae9de9b9dd118edf)
