Ecological security examines how disruption across Earth systems alters human, national, and global security. It widens the aperture beyond climate alone to include biosphere instability, pollution and plastics, biogeochemical imbalance, ecological crime, and eco-amplifying processes such as antimicrobial resistance and zoonotic spillover — all of them products of how human civilization has reorganized the planet’s living systems.

Ecological security is integral to human, national, and global security. Traditional security institutions, doctrines, and architectures often relegate these stresses to the realm of so-called environmental issues, but in reality, they are deeply-rooted societal, economic, and political issues. EFG uses the term ecological security distinctly from environmental security, which has evolved over time to focus primarily on a few abiotic concerns, such as climate and water security. The word environment also, unfortunately, connotes a disconnect between humans and the rest of the planet, rather than recognizing that human civilization is embedded in and intertwined with Earth systems and processes.

Ecological security threats can lead to outcomes traditionally recognized as security risks — resource conflict, geopolitical tension, and state fragility. Yet security doctrine has been slow to treat biodiversity loss, pollution, and plastics as core concerns, leaving institutions increasingly mismatched to the threats emerging in the Anthropocene era.

Ecological disruption reaches security outcomes through multiple pathways: habitat loss erodes resource bases that sustain communities; pollution undermines health and agricultural productivity; climate change amplifies instability across food, water, and migration systems; and the collapse of ecosystem services removes the material foundations on which stable societies depend.

Ecological Futures Group analyzes and articulates the pathways by which ecological disruption translates into security outcomes, developing research methodologies that bridge security analysis and Earth system science. The goal is a widely acknowledged security doctrine — one that treats biosphere instability, pollution, eco-amplification, biogeochemical imbalances, ecological crime, and climate change as the core security issues they are.

Pathways to Insecurity

Ecological disruption does not stay in forests, rivers, coastlines, or bodies. It moves through food systems, disease dynamics, migration pressures, infrastructure stress, political legitimacy, and interstate competition. Understanding these pathways — the mechanisms by which Earth-system stress becomes human, national, or geopolitical consequence — is the core analytical task of ecological security research.

Uncertainties and Open Questions

Ecological security is a young field facing a wide landscape of uncertainty. The pace and magnitude of Earth-system change remain difficult to predict. The social and political consequences of specific disruptions depend on context, institutional capacity, and compounding pressures. Many of the most important risks — cascading effects across systems, threshold behaviors, compounding crises — are precisely those that existing analytic frameworks handle least well. Acknowledging these gaps is not a weakness; it is part of rigorous analysis.
