Kibera, Mathare, Mukuru — the politics of upgrading versus replacement

<p>Nairobi&#x27;s three largest informal settlements — Kibera, Mathare, and Mukuru — together house roughly 1.2 to 1.5 million residents, depending on whose census you accept. The official population numbers have always been a political instrument: state actors who favour clearance prefer lower estimates, residents and advocacy groups prefer higher ones. The Kenya National Bureau of Statistics 2019 enumeration put the three at about 950,000; the Slum Dwellers International / Muungano wa Wanavijiji household survey of 2023 reached 1.4 million. The truth probably lies between.</p> <p>The choice between *upgrading* and *replacement* has been the central planning question for these settlements since the early 2000s. The Kenya Slum Upgrading Programme (KENSUP), established 2004, started with replacement — clear, build apartment blocks, decant residents in. The Soweto East decant village in Kibera was the flagship. The flagship failed at predictable points: original residents could not afford the rents in the new blocks, sold their occupancy rights to middle-income tenants, and moved back into neighbouring informal areas. The state had built housing; it had not housed the people it was supposed to house.</p> <p>The Mukuru Special Planning Area, gazetted in 2017, took the lessons. SPA-Mukuru is an *in-situ* upgrading programme — improve infrastructure (water, sanitation, roads, electrification) on the existing footprint, formalise tenure incrementally, leave household structures in place except where streets need widening. The programme is running on a fifteen-year horizon. Five years in, the visible infrastructure improvements — Mukuru&#x27;s first sealed access roads, reticulated water mains in two of the eight sub-locations, a county-funded primary school complex — are real and have not displaced residents.</p> <p>The political economy is what makes upgrading work where it works. SPA-Mukuru was drafted with intensive participation from the Mukuru Consortium — federation chapters of Slum Dwellers International, Muungano, Akiba Mashinani Trust. The residents had drafted *their* version of the upgrading plan before the County government drafted its version, and the negotiated final plan absorbed roughly 80% of the resident-side proposals. That is the variable that distinguishes Mukuru from earlier replacement projects, more than the technical content of the plan.</p> <p>The lesson generalises. Upgrading versus replacement is not, in the end, a technical or financial question. It is a question of who has standing to negotiate the upgrade. In settlements where federated tenant organisations exist and are politically credible, upgrading is feasible. Where they don&#x27;t, replacement remains the default — and the replacements continue to fail at the same predictable points.</p>
