Abuja vs Bauchi
Tree cover and air quality for both, measured the same way: Sentinel-2 imagery at 10 m detail over a 2 km radius from each city centre, and the live US EPA air quality index. Same radius and same index, so the two numbers compare directly.
Abuja has more tree cover — 38.7% against 16.2%.
Bauchi has cleaner air right now — AQI 37 against 48.

Air quality in detail
What each city is breathing
Concentrations in µg/m³, measured at the same moment as the index above. Lower is better in every row. Abuja is read from nearby ground stations and Bauchi is modelled — worth knowing, since the two are not quite like for like.

Reading these numbers
What is actually being measured
Tree cover
The share of ground under canopy inside a 2 km radius of each city centre, read from Sentinel-2 satellite imagery at 10 m detail. It is a measurement of that circle, not of the whole municipality — which is exactly what makes the two comparable, since city boundaries are drawn to wildly different rules around the world. Abuja leads here at 38.7%.
Air quality index
The live US EPA index, computed from current pollutant concentrations — ground stations where a city has them nearby, and a model everywhere else. It moves hour to hour, so this is a snapshot rather than a verdict on either place: Abuja reads 48 (good) and Bauchi reads 37 (good) right now.
Frequently asked
Abuja and Bauchi, answered
Which has more trees, Abuja or Bauchi?
Abuja, with roughly 121,580 trees inside its 2 km radius against 50,894. Tree cover tells a slightly different story from raw count: Abuja has the denser canopy at 38.7%.
Which has better air quality, Abuja or Bauchi?
Bauchi right now, at AQI 37 against 48 — a gap of 11 points. This is a live reading rather than an annual average, so it can reverse within a day.
How many more trees does each city need?
Abuja needs about 0 more to reach its canopy target, and Bauchi about 43,354. The target is the same share of ground for both, so the figures are directly comparable.
Are these two measured the same way?
Yes — that is the point of the page. Identical radius, identical satellite source at 10 m detail, and the same US EPA index for air. Nothing here is adjusted for population, city limits or climate, so the numbers describe the same-sized circle of ground in each place.
