Summary
Solidarity infrastructure is the lasting support that lets solidarity between movements outlive the crisis that sparked it. Adaku Utah and Deepa Iyer of the Building Movement Project set the idea out in Nonprofit Quarterly in February 2026. Solidarity that arrives in bursts, they write, “tends to recede when the crisis subsides or another one takes its place”.
They name four interconnected parts: skills such as building trust and handling conflict; spaces where relationships and strategy are built; scaffolding, the shared frameworks and tools that help groups coordinate; and structures, the agreements and governance that make cooperation durable. Without sustained investment, they warn, organisers must start again with each new crisis.
Rationale
Part 2 names “relational (or ‘solidarity’) infrastructure” first among the conditions this work needs. We came to this version through Julia Roig, whom we interviewed, and its four parts give that phrase practical content.
