Deforestation · 2001–2025
Which country has lost more forest, Ethiopia or Japan?
Japan has lost more: about 1.02 million ha of forest from 2001 to 2025, against 559,000 ha in Ethiopia, or 1.8 times as much. 108,000 ha of Japan'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: 2012, with 41,800 ha lost.
Worst year: 2016, with 54,800 ha lost.

Behind the averages
The cities behind Ethiopia and Japan
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: 30 in Ethiopia and 207 in Japan, 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. Japan rests on 207 cities against 30, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.
Frequently asked
Ethiopia vs Japan: your questions answered
Is Japan cleaner than Ethiopia?
On air quality, yes, right now: Japan's cities average AQI 47 against 60 on the US EPA index. These are live readings averaged across cities, so the gap moves with the weather.
Which country has lost more forest, Ethiopia or Japan?
Japan has lost more: about 1.02 million ha of forest from 2001 to 2025, against 559,000 ha in Ethiopia, or 1.8 times as much. 108,000 ha of Japan's was cleared for good, for farms, mines or towns; the rest burned, was logged or can grow back.

How many cities are the Ethiopia and Japan figures based on?
30 measured cities in Ethiopia and 207 in Japan. 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.
Does this cover the whole of Ethiopia and Japan?
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.
