Al ‘Amārah vs Najaf

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.

Al ‘Amārah has more tree cover — 2.3% against 1.7%.

Najaf has cleaner air right now — AQI 78 against 151.

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. Al ‘Amārah leads here at 2.3%.

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: Al ‘Amārah reads 151 (unhealthy) and Najaf reads 78 (moderate) right now.

Frequently asked

Al ‘Amārah and Najaf, answered

Which has more trees, Al ‘Amārah or Najaf?

Al ‘Amārah, with roughly 7,204 trees inside its 2 km radius against 5,341. Tree cover tells a slightly different story from raw count: Al ‘Amārah has the denser canopy at 2.3%.

Which has better air quality, Al ‘Amārah or Najaf?

Najaf right now, at AQI 78 against 151 — a gap of 73 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?

Al ‘Amārah needs about 118,083 more to reach its canopy target, and Najaf about 88,907. 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.
