This book explores various dimensions of the nexus between climate changeClimate change , human securityHuman security , and politics and the need for a rethinking of these interconnected issues. Multiple chapters examine the urgent and complex intersections of climate change, human security, and political power dynamics. Authors stress the need to transcend disciplinary boundaries and adopt interdisciplinary approaches to understand how climate-related risks interact with socio-political tensions. Conflict, military preparedness, and environmental degradation are shown to be tightly interlinked. Effective governance, both formal and community-based, emerges as essential in mitigating these crises. Contributors also explore how grassroots movements, NGOs, and subnational actors influence climate governance. Transnational issues like plastic pollution and urban sprawl demand new collaborative frameworks. Meanwhile, global power asymmetries persist, with fossil fuel lobbies and petrostates resisting meaningful climate action. In Europe, rural backlash against top-down climate policies has fueled populist nationalism while in the Pacific, climate nationalism unites vulnerable nations under a justice-driven banner. Indigenous knowledge systems and land-use practices offer alternative, resilient responses to climate threats. Authors highlight the potential of native seeds, traditional farming, and multilevel governance to preserve biodiversity and empower marginalized communities. Ultimately, collective resilience requires rethinking development, amplifying underrepresented voices, and pursuing climate security as a shared global responsibility rooted in justice and inclusion.
