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. Debrecen leads here at 28.7%.
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: Bağcılar reads 90 (moderate) and Debrecen reads 44 (good) right now.
Frequently asked
Bağcılar and Debrecen, answered
Which has more trees, Bağcılar or Debrecen?
Debrecen, with roughly 90,164 trees inside its 2 km radius against 19,164. Tree cover tells a slightly different story from raw count: Debrecen has the denser canopy at 28.7%.
Which has better air quality, Bağcılar or Debrecen?
Debrecen right now, at AQI 44 against 90 — a gap of 46 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?
Bağcılar needs about 75,084 more to reach its canopy target, and Debrecen about 4,084. 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.
