Iraq vs Nigeria Air quality index (AQI) and deforestation
Iraq has cleaner air than Nigeria right now: its cities average AQI 72 against 101.
At ground stations alone, which measure rather than estimate, the averages are Iraq 106 (3 cities) and Nigeria 81 (13 cities), which puts Nigeria ahead instead. Nigeria has lost more forest since 2001. Nigeria 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, Iraq or Nigeria?
Nigeria has lost more: about 1.56 million ha of forest from 2001 to 2025, against 138 ha in Iraq, or 11344 times as much. 1.44 million ha of Nigeria'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: 2003, with 19 ha lost.
Worst year: 2017, with 172,000 ha lost.

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: 49 in Iraq and 99 in Nigeria, 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. Nigeria rests on 99 cities against 49, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.
Frequently asked
Iraq vs Nigeria: your questions answered
Is Iraq cleaner than Nigeria?
On air quality, yes, right now: Iraq's cities average AQI 72 against 101 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 Iraq 106 (3 cities) and Nigeria 81 (13 cities), which puts Nigeria ahead instead.
Which country has lost more forest, Iraq or Nigeria?
Nigeria has lost more: about 1.56 million ha of forest from 2001 to 2025, against 138 ha in Iraq, or 11344 times as much. 1.44 million ha of Nigeria'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, Iraq or Nigeria?
Nigeria does: its measured cities average 19.4% tree cover against 5.1%, a gap of 14.3 percentage points.
How many cities are the Iraq and Nigeria figures based on?
49 measured cities in Iraq and 99 in Nigeria. 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 Iraq and Nigeria?
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.
