Deforestation · 2001–2025
Which country has lost more forest, Poland or South Africa?
South Africa has lost more: about 1.66 million ha of forest from 2001 to 2025, against 1.52 million ha in Poland. 169,000 ha of South Africa'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: 2018, with 96,800 ha lost.
Worst year: 2006, with 105,000 ha lost.

Behind the averages
The cities behind Poland and South Africa
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: 39 in Poland and 66 in South Africa, 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. South Africa rests on 66 cities against 39, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.
Frequently asked
Poland vs South Africa: your questions answered
Is South Africa cleaner than Poland?
On air quality, yes, right now: South Africa's cities average AQI 60 against 68 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 Poland 69 (32 cities) and South Africa 58 (30 cities).
Which country has lost more forest, Poland or South Africa?
South Africa has lost more: about 1.66 million ha of forest from 2001 to 2025, against 1.52 million ha in Poland. 169,000 ha of South Africa'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, Poland or South Africa?
Poland does: its measured cities average 37.6% tree cover against 21.8%, a gap of 15.8 percentage points.
How many cities are the Poland and South Africa figures based on?
39 measured cities in Poland and 66 in South Africa. 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 Poland and South Africa?
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.
