What each city is breathing
Concentrations in µg/m³, measured at the same moment as the index above. Lower is better in every row. Pointe-Noire is read from nearby ground stations and Bandundu Province 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. Bandundu Province leads here at 35.9%.
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: Bandundu Province reads 55 (moderate) and Pointe-Noire reads 88 (moderate) right now.
Frequently asked
Bandundu Province and Pointe-Noire, answered
Which has more trees, Bandundu Province or Pointe-Noire?
Bandundu Province, with roughly 110,866 trees inside its 2 km radius against 14,556. Tree cover tells a slightly different story from raw count: Bandundu Province has the denser canopy at 35.9%.
Which has better air quality, Bandundu Province or Pointe-Noire?
Bandundu Province right now, at AQI 55 against 88 — a gap of 33 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?
Bandundu Province needs about 0 more to reach its canopy target, and Pointe-Noire about 69,419. 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.
