Al Manāqil vs Sennar
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.
Sennar has more tree cover — 42.5% against 2.3%.
Al Manāqil has cleaner air right now — AQI 59 against 61.

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. Sennar leads here at 42.5%.
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 Manāqil reads 59 (moderate) and Sennar reads 61 (moderate) right now.
Frequently asked
Al Manāqil and Sennar, answered
Which has more trees, Al Manāqil or Sennar?
Sennar, with roughly 124,973 trees inside its 2 km radius against 7,226. Tree cover tells a slightly different story from raw count: Sennar has the denser canopy at 42.5%.
Which has better air quality, Al Manāqil or Sennar?
Al Manāqil right now, at AQI 59 against 61 — a gap of 2 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 Manāqil needs about 87,022 more to reach its canopy target, and Sennar 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.
