Deforestation · 2001–2025

Which country has lost more forest, Indonesia or Vietnam?

Indonesia has lost more: about 33 million ha of forest from 2001 to 2025, against 3.85 million ha in Vietnam, or 8.6 times as much. 25 million ha of Indonesia'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.

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: 156 in Indonesia and 114 in Vietnam, 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. Indonesia rests on 156 cities against 114, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.

Frequently asked

Indonesia vs Vietnam: your questions answered

Is Vietnam cleaner than Indonesia?

On air quality, yes, right now: Vietnam's cities average AQI 53 against 81 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 Indonesia 96 (39 cities) and Vietnam 77 (20 cities).

Which country has lost more forest, Indonesia or Vietnam?

Indonesia has lost more: about 33 million ha of forest from 2001 to 2025, against 3.85 million ha in Vietnam, or 8.6 times as much. 25 million ha of Indonesia'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, Indonesia or Vietnam?

Vietnam does: its measured cities average 35.8% tree cover against 28.0%, a gap of 7.8 percentage points.

How many cities are the Indonesia and Vietnam figures based on?

156 measured cities in Indonesia and 114 in Vietnam. 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 Indonesia and Vietnam?

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.
