    • The Paris Agreement has the potential to facilitate ambitious climate action: a reply to ‘Why do climate change negotiations stall? Scientific evidence and solutions for some structural problems’ by Ulrich J. Frey and Jazmin Burgess 

      Kallbekken, Steffen (Peer reviewed; Journal article, 2022)
      Frey and Burgess (2022) argue that climate change negotiations have stalled because of the global public goods nature of the problem, the consensus decision-making process and the lack of institutions to enforce sanctions. ...
    • Pastoral herding strategies and governmental management objectives: predation compensation as a risk buffering strategy in the Saami reindeer husbandry
