This thesis deals with identification, analysis and critical assessment of challenges for international relations arising in the Arctic in connection with global climate change, which results mainly into decrease of the sea ice. Copenhagen School forms the primary theoretical bedrock of the thesis. The thesis maps the approach of different theoretical paradigms to the Arctic region throughout the history and on this basis it justifies the relevance of application of the concept of security sectors defined by Copenhagen School on the region. The thesis also maps the current governance mechanisms of the Arctic region as far as international law and institutional arrangements are concerned. The analysis of concrete challenges for international relations is structured according to the sectors of security defined by Copenhagen School. Thus, challenges in the environmental, societal, economic, political and military sectors are examined.

This study investigates how to enhance Sámi participation in EU Arctic policymaking processes by adopting and adapting participatory practices from the Arctic Council. Through a qualitative content analysis of policy documents and elite interviews, the study identifies that the EU can learn from the Arctic Council by recognizing the Sámi as internal actors, developing their collaborative platforms, and integrating Indigenous Knowledge into policymaking processes. This thesis develops a conceptual framework, integrating the concepts of procedural and intergovernmental self-determination, epistemic belonging, and organizational interdependency to define meaningful Indigenous participation and influence, which guides the analysis. Using this framework, the study contrasts the Arctic Council’s successful practices, where Indigenous Peoples Organizations are treated as equals, with the EU’s tendency to view the Sámi as an external Indigenous group outside of EU borders. The study identifies opportunities for the EU to translate participatory mechanisms that reflect the Sámi’s unique position and integrate their knowledge, as well as barriers such as treaty and resource constraints. By translating Artic Council practices into soft-law, the EU can create an inclusive atmosphere, contributing to meaningful Sámi participation.

The Arctic region is changing. This is an oft-cited statement researcher, policy-makers and the general public say about the Arctic. But who can change the Arctic order? This academic paper is interested in determine Greenland’s role and ‘actorness’ in this changeable region. Adopting an interpretivist approach, I advocate to embrace the narrative turn in IR as a useful move to understand how Greenland, as a sub-state regional entity, can enhance its agency capacity in Arctic affairs. Using phronetical case study, govermentality and narrative analysis as main methodologies, this study decipher how the Arctic governance has changed and been shaped by different narratives and governmental practices. Greenland’s possibilities to exercise more power have been analysed through the lenses of ontological security theory because this theory is intimately related to human agency. However, this theory presents several challenges that must be overcome by doing a revision of the theory. The final results are discusses in a reflexive manner adopting four phronetical value-rational questions that policy-makers should take into account when planning any relevant strategic action, such as Greenland’s visibility and empowerment in Arctic affairs.
