Mainstreaming is one of the most frequently used terms in contemporary policy English. It signals a structural shift: the issue is no longer addressed via a separate scheme or special ministry, but is woven into every department’s core work.

Gender mainstreaming, the dominant usage, came from the 1995 Beijing Platform for Action and was reinforced by UNSC Resolution 1325 (2000) on women, peace, and security. Today the term applies equally to climate mainstreaming in finance commissions, DRR mainstreaming in Sendai-aligned plans, and disability mainstreaming under the RPwD Act. Mains essays on inclusion are incomplete without it.
