Although issues linked to global environmental change and its role within peace, conflict andsecurity have been subject to social and political controversy for years, they are still notsufficiently respected by energy companies, trade unions, national governments andinternational institutions alike. Through applying the tools of a single instrumental case studylinked to the application of discourse analysis I, this study explores the process of securitizationof the environment in the extraordinary case of the resistance and occupation surrounding theHambach Forest, thereby countering the widely held assumption that collective action aimedat radically changing existing structures is not possible. The particular exploratory focus is puton the way this non-conventional environmental security discourse has been created within aredefined securitization framework. By challenging the traditional focus of securitizationtheory on top-down construction through elites, this study provides a broadened, bottom-upaccount of environmental securitization stemming from local civil society actors as nonpowerholdersthat effectively proclaim their recognition of the environment’s intrinsic valuefrom a grassroots level. Consequently, it argues for the significance of securitization as creativeprocess of alerting policy makers, political leaders and the broader society to the emergency ofclimate change and global environmental degradation symbolized through the specific case ofHambach Forest.

This thesis addresses indigenous groups agency in trade governance to enhance their ability to affect international decision-making that benefits their capability to sustainable development. It conducts a case study of Articulation of Indigenous People Brazil (APIB) in the EU-Mercosur Agreement and utilizes Eimers (2020) theory of subaltern social movement theory to establish: what strategies the APIB have used in the decision-making processes of the “Mercosur Agreement?  This theory allows consideration of indigenous agency and the effect of post-colonial structures on their capability to keep control over their realties. To collect data on this topic the author uses qualitative semi-structured interviews and qualitative thematic text analysis. The thesis finds that framing strategies of claims enabled alliance-building in Brazil and Transnational Advocacy Coalitions, which used international norms to enhance indigenous interests. However, has post-colonial structures hindered APIB´s ability to enhance interest in Brazil and silenced indigenous interests in governmental representation in the making of the EU-Mercosur.
