The Anthropocene and International Relations: A Critical Analysis

The concept of the Anthropocene, a geological epoch marked by human activity as the primary force shaping Earth’s systems, has sparked significant debate within International Relations (IR). While some argue it signifies a radical transformation of the discipline, this article contends that the Anthropocene expands rather than replaces existing IR frameworks, particularly within constructivist and critical traditions.

Defining the Anthropocene and Its Implications

Coined by Paul Crutzen in 2002, the Anthropocene denotes a “human-dominated” era where human actions profoundly impact geological and ecological processes. As Dipesh Chakrabarty notes, humans now wield a “geological force,” altering climate, biodiversity, and ecosystems at unprecedented scales. This epoch challenges traditional IR paradigms by shifting focus from state-centric security to planetary-scale challenges.

The Anthropocene forces IR scholars to confront ontological questions—how we understand existence and reality—rather than solely epistemological ones. It critiques modernist assumptions that position humans as separate from nature, advocating for a “planetary” perspective that recognizes interconnectedness between human and non-human systems.

Reconfiguring Security and Agency

Traditional security studies, rooted in state-centric and military-focused frameworks, face reevaluation. The Anthropocene introduces “posthuman security,” which considers non-human actors—ecosystems, climate systems, and the Earth itself—as integral to global politics. This aligns with Ulrich Beck’s concept of a “risk society,” where modernity’s own advancements generate crises requiring new solutions.

Posthumanism, a philosophical perspective challenging anthropocentrism, argues that non-human entities possess agency. This shifts security discourse from protecting human lives alone to addressing socio-ecological vulnerabilities. For instance, climate change is not merely a political or economic issue but a complex
