Territorial information to analize crop and livestock disconnection_reconnection in some world regions

This dataset contains information on regions in Spain, France, China, and the USA, used to create spatial maps illustrating crop–livestock disconnection at the county or provincial scale. It was developed as part of the collaboration for the Special Issue Reducing Nitrogen Waste Through Crop and Livestock Reconnection, edited by Luis Lassaletta, Alberto Sanz-Cobeña, Lin Ma, Sheri Spiegal, Corentin Pinsard, Pytrik Reidsma (†), and Val Snow.
