What each city is breathing
Concentrations in µg/m³, measured at the same moment as the index above. Lower is better in every row. New Cairo is read from nearby ground stations and Al Ḩawāmidīyah 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. Al Ḩawāmidīyah leads here at 40.9%.
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 Ḩawāmidīyah reads 58 (moderate) and New Cairo reads 164 (unhealthy) right now.
Frequently asked
Al Ḩawāmidīyah and New Cairo, answered
Which has more trees, Al Ḩawāmidīyah or New Cairo?
Al Ḩawāmidīyah, with roughly 128,491 trees inside its 2 km radius against 31,416. Tree cover tells a slightly different story from raw count: Al Ḩawāmidīyah has the denser canopy at 40.9%.
Which has better air quality, Al Ḩawāmidīyah or New Cairo?
Al Ḩawāmidīyah right now, at AQI 58 against 164 — a gap of 106 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 Ḩawāmidīyah needs about 0 more to reach its canopy target, and New Cairo about 94,248. 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.
