Beirut vs Tyre
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.
Tyre has more tree cover — 11.7% against 9.8%.
Beirut has cleaner air right now — AQI 16 against 59.

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. Tyre leads here at 11.7%.
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: Beirut reads 16 (good) and Tyre reads 59 (moderate) right now.
Frequently asked
Beirut and Tyre, answered
Which has more trees, Beirut or Tyre?
Beirut, with roughly 25,677 trees inside its 2 km radius against 6,616. Tree cover tells a slightly different story from raw count: Tyre has the denser canopy at 11.7%.
Which has better air quality, Beirut or Tyre?
Beirut right now, at AQI 16 against 59 — a gap of 43 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?
Beirut needs about 52,926 more to reach its canopy target, and Tyre about 10,348. 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.
