Abengourou vs Bonon

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.

Bonon has more tree cover — 40.3% against 31.5%.

Bonon has cleaner air right now — AQI 14 against 18.

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. Bonon is read from nearby ground stations and Abengourou 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. Bonon leads here at 40.3%.

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: Abengourou reads 18 (good) and Bonon reads 14 (good) right now.

Frequently asked

Abengourou and Bonon, answered

Which has more trees, Abengourou or Bonon?

Bonon, with roughly 126,606 trees inside its 2 km radius against 98,960. Tree cover tells a slightly different story from raw count: Bonon has the denser canopy at 40.3%.

Which has better air quality, Abengourou or Bonon?

Bonon right now, at AQI 14 against 18 — a gap of 4 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?

Abengourou needs about 0 more to reach its canopy target, and Bonon about 0. 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.
