Interdependent

Interdependence describes a condition or state in which two or more entities rely on each other to function, survive, or achieve outcomes. Interdependence implies mutual dependence and shared fate rather than unilateral dependence or complete independence. The term draws from Latin roots inter- meaning 'between' and dependere meaning 'to hang from' or 'to rely on.' In modern usage, it is especially associated with systems thinking, where components of a whole affect one another through feedback and reciprocal influence.

In practical terms, interdependence appears in ecological, social, economic, and technological networks. In ecosystems, species rely on one another for food, pollination, and nutrient cycles; changes to one member can cascade through the system. In human groups and communities, individuals depend on others for support, services, and collaboration, while contributing to the welfare of the group. Economies function through interdependent markets, supply chains, and institutions, such that disruption in one locale or sector can ripple globally. Technological networks and information systems also exhibit interdependence, with systems layered and linked to enable collective capability.

Interdependence is distinct from mere cooperation or dependence. It emphasizes reciprocal obligation and shared outcomes, and it can enhance resilience by spreading risk, though it can also propagate vulnerabilities. Understanding interdependence supports approaches to governance, sustainability, and conflict resolution that recognize mutual stake and the value of coordination.
