Humanitarian & development policy
Humanitarian-Development Nexus
Definition
The humanitarian-development nexus is the coordinated working of humanitarian, development, and — in the full "triple nexus" formulation — peace actors across short-, medium-, and long-term time horizons, so that relief also reduces need, risk, and vulnerability. It is codified in the 2019 OECD DAC Recommendation on the Humanitarian-Development-Peace Nexus, a common standard for collective action in fragile and conflict-affected settings.

Overview
What it means
Crises have become protracted — the average displacement lasts years, not months — yet the aid system still funds and organises relief and development separately, leaving people stranded between the two. The nexus asks actors to programme toward shared "collective outcomes", to use joined-up analysis and planning, and to finance flexibly across the divide.
It is contested where closer integration risks compromising humanitarian principles.
How it is used
The nexus frames UN reform, donor strategies for fragile states, refugee-response compacts, and anticipatory-action programming.
Why it matters
Most humanitarian need now comes from long crises; only a nexus approach can address both the suffering and its causes.
