The Facts

  • Tolullah Oni, a University of Cambridge urban epidemiologist, founded the non-profit UrbanBetter in 2019 to connect researchers and residents in diagnosing city health problems. Nature only
  • UrbanBetter's civic arm, Cityzens Hubs, operates in 11 African cities plus Bogotá and Bangkok; its research arm, the UrbanBetter Academy, has a centre in Cambridge. Nature only
  • UrbanBetter started with a US$300,000 unrestricted grant from Unorthodox Philanthropy, sponsored by the San Francisco-based Lampert Byrd Foundation. Nature only
  • In 2025, Cityzens in Nairobi collected air-pollution data and held a community assembly proposing cleaner public transport, more trees and green spaces, and less open burning of rubbish; Oni says these points fed into the Nairobi City County Air Quality Action Plan. Nature only
  • Before the 2025 Lagos City Marathon, the local Cityzens Hub partnered with World Athletics' Running for Clean Air project; residents ran the route monthly through 2025 wearing air-quality sensors and logging geotagged data via the UrbanBetter app. Nature only

Context

Nature interviewed Tolullah Oni about UrbanBetter, a non-profit that trains residents and local researchers to collect and analyse data on air quality, heat and other urban conditions, then use it to lobby for policy change. Oni, born in Nigeria and now based in the UK, says on-the-ground participation is needed for diagnoses and solutions to reflect lived realities.

The hubs specialise differently: Lagos works on physical activity, air pollution and heat, while Bogotá has worked on transport, cycling and car-free days. The figures reported come from Oni's account and are not independently verified; the 60% pollution reduction was found by some runners rather than in a formal study.

How the Agent Panel Scored This

Independent AI personas each scored importance 1–10; the story's score is a trimmed mean (highest and lowest votes dropped). Vote spread: 1.

3 News Editor This is a feature profile of a non-profit's citizen-science programme, reporting ongoing community data collection and a few local policy inputs rather than a discrete, large-scale concrete event affecting many people.
2 Business Analyst This is a feature interview about a non-profit's community data-collection program with no major market-moving action, regulatory shift, or large-scale immediate impact, so it is niche and low-importance news.
2 Informed Citizen This is a feature profile of a non-profit's citizen-science model with local, small-scale activities and no concrete policy change or broad impact on ordinary people beyond niche participants.
