Climate Change as a Conflict Multiplier in Fragile States: Disaggregating the Causal Pathways between Environmental Stress and Political Violence

Abstract

The relationship between climate change and political violence has emerged as one of the most contested and consequential debates in contemporary international relations and security studies. Existing scholarship has advanced the proposition that climate change serves as a "threat multiplier," yet this framing remains analytically imprecise, theoretically underdeveloped, and empirically inconclusive. The dominant literature tends to treat climate-conflict relationships as essentially linear, positing that environmental stress directly and proportionally escalates into political violence. This article challenges that presumption. Drawing upon a qualitative, explanatory, post-positivist research design and employing structured comparative analysis, process tracing, and thematic synthesis of peer-reviewed scholarship published between 2022 and 2026, this study identifies and theorizes five interconnected causal pathways through which climate-induced environmental stress contributes to political violence in fragile states: livelihood insecurity, governance erosion, institutional collapse, grievance formation, and political mobilization. The article's central theoretical contribution is the development of the Cascade Fragility Mechanism (CFM), an original conceptual framework proposing that climate shocks do not directly produce violence; rather, they initiate a sequential and compounding process whereby environmental stress degrades livelihoods, overwhelms governance capacity, erodes institutional legitimacy, amplifies socio-political grievances, and enables violent political mobilization. The analysis further proposes a refined analytical proposition: climate change functions not merely as a threat multiplier but as a fragility accelerator that structurally reshapes political opportunity for violent actors in vulnerable states. The study carries important implications for peacebuilding policy, climate adaptation programming, and fragile state governance reform. It concludes by recommending that international institutions, national governments, and development organizations integrate climate risk into conflict-sensitive governance frameworks as a matter of urgent strategic priority.
