Dammam vs Manama
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.
Manama has more tree cover — 2.8% against 1.9%.
Dammam has cleaner air right now — AQI 135 against 152.

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. Manama leads here at 2.8%.
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: Dammam reads 135 (unhealthy for sensitive groups) and Manama reads 152 (unhealthy) right now.
Frequently asked
Dammam and Manama, answered
Which has more trees, Dammam or Manama?
Manama, with roughly 8,260 trees inside its 2 km radius against 5,969. Tree cover tells a slightly different story from raw count: Manama has the denser canopy at 2.8%.
Which has better air quality, Dammam or Manama?
Dammam right now, at AQI 135 against 152 — a gap of 17 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?
Dammam needs about 103,987 more to reach its canopy target, and Manama about 109,738. 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.
