Spain vs Turkey Air quality index (AQI) and deforestation
Spain has cleaner air than Turkey right now: its cities average AQI 21 against 77.
At ground stations alone, which measure rather than estimate, the averages are Spain 24 (30 cities) and Turkey 81 (67 cities). Spain has lost more forest since 2001. Spain has more tree cover in its cities.
Updated . Lower is better on the US EPA index: 0–50 is Good, above 300 is Hazardous. Measured by Airleaf.

Deforestation · 2001–2025
Which country has lost more forest, Spain or Turkey?
Spain has lost more: about 1.79 million ha of forest from 2001 to 2025, against 843,000 ha in Turkey, or 2.1 times as much. 81,100 ha of Spain's was cleared for good, for farms, mines or towns; the rest burned, was logged or can grow back.
The whole country, from the yearly satellite maps of forest loss: unlike the city averages above, this counts every forest, not just the land around cities.
Worst year: 2025, with 153,000 ha lost.
Worst year: 2021, with 79,200 ha lost.

Behind the averages
The cities behind Spain and Turkey
An average says nothing about how far apart the best and worst places are. These are the measured cities at each end.
Reading these numbers
What a country average is, and is not
It is a mean of cities
Not a national statistic. Each figure is the average across the cities Airleaf has measured: 57 in Spain and 95 in Turkey, each read over the same 2 km radius, on the US EPA index. Rural land and unmeasured towns are not in it.
Coverage shapes the number
A country measured mostly in its capital reads differently from one measured across dozens of towns. Turkey rests on 95 cities against 57, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.
Frequently asked
Spain vs Turkey: your questions answered
Is Spain cleaner than Turkey?
On air quality, yes, right now: Spain's cities average AQI 21 against 77 on the US EPA index. These are live readings averaged across cities, so the gap moves with the weather. At ground stations alone, which measure rather than estimate, the averages are Spain 24 (30 cities) and Turkey 81 (67 cities).
Which country has lost more forest, Spain or Turkey?
Spain has lost more: about 1.79 million ha of forest from 2001 to 2025, against 843,000 ha in Turkey, or 2.1 times as much. 81,100 ha of Spain's was cleared for good, for farms, mines or towns; the rest burned, was logged or can grow back.
Which country has more tree cover, Spain or Turkey?
Spain does: its measured cities average 14.3% tree cover against 14.2%, a gap of 0.1 percentage points.
How many cities are the Spain and Turkey figures based on?
57 measured cities in Spain and 95 in Turkey. Every one was read the same way, so the two averages are directly comparable, but a country with more measured cities has the more settled figure.
Why are there two air quality averages for each country?
The first covers every measured city, using a ground station where one is close and a model estimate everywhere else. The second counts only cities with a current station reading, which is measured rather than estimated but covers fewer places. Airleaf's world rankings use the station figures only.
Does this cover the whole of Spain and Turkey?
The air and tree figures are not: they are the cities Airleaf has measured, each over the same 2 km radius, so treat them as a comparison of urban air and urban tree cover. The forest figures are: they count every forest in the country.
