Reindeer husbandry under global change in the tundra region of Northern Fennoscandia
The Nordic Centre of Excellence (NCoE) TUNDRA (“How to preserve the tundra in a changing climate”) has been a 5-year project (2011–15) within the Top-Level Research Initiative (TRI) by NordForsk. This report combines the key results and a synthesis of the NCoE TUNDRA with earlier research to provide...
