No Triple Nexus coordination mechanism exists at the Nairobi level today. Mathare, further down, is currently the only level with real coordination data — this page says that plainly rather than filling the gap with placeholder content.
A Nairobi County coordination mechanism would need buy-in across its sub-counties and wards, a shared way of tracking which organisations work where, and agreement on how humanitarian, development and peacebuilding actors report to each other. None of that exists today.
Mathare, one of Nairobi’s informal settlements, is where the Nexus Bridge programme is building and testing this approach first — see the Mathare page for the real, working example.
If you know of Triple Nexus coordination efforts at the Nairobi level we should be aware of, tell us here.
