How much forest has Nepal lost?

Since 2001, Nepal has lost about 61,600 hectares of forest (about 86,000 football pitches): 1.2% of the forest it had in 2000. Most of it (54%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations.

Nepal as a whole

43.6% of Nepal was forested as of 2024, against a 30% benchmark. That already clears the benchmark — the city reports above show where cover is still thin locally. Source: World Bank (FAO).

Air quality in Nepal: your questions answered

What is the air quality in Nepal today?

Right now the 13 cities Airleaf measures in Nepal average AQI 132 (unhealthy for sensitive groups). The worst air is in Janakpur, at AQI 225, and the cleanest in Birendranagar, at AQI 81. At ground stations alone, which measure rather than estimate, the average is AQI 145 across 10 cities. 69% of the 13 measured cities are over AQI 100 today, where the air stops being fine for sensitive groups.

Which city in Nepal has the worst air right now?

Janakpur, at AQI 225 (Very unhealthy) on the US EPA index. Health alert — everyone should avoid long outdoor exertion.

Which city in Nepal has the cleanest air right now?

Birendranagar, at AQI 81 (Moderate). Both lists rank current readings, from ground stations wherever Nepal has at least three cities with one.

Is the air in Nepal safe to breathe today?

It depends on the city. 4 cities are Moderate, 5 cities are Unhealthy for sensitive groups, 3 cities are Unhealthy, 1 city is Very unhealthy. At the national average of AQI 132: Sensitive groups should limit long or intense outdoor activity.

How much forest has Nepal lost since 2001?

About 61,600 ha from 2001 to 2025, 1% of the forest it had in 2000, from the University of Maryland's yearly satellite maps of forest loss. 33,100 ha of it was cleared for good, for farms, mines or towns.

Which city in Nepal has the most trees?

Pokhara, with 56.5% tree cover within 2 km of its center, measured from Sentinel-2 satellite images.

How does Airleaf measure air quality in Nepal?

Each city's reading is the US EPA air quality index, from ground monitoring stations where one has reported recently nearby, and from the CAMS atmospheric model elsewhere; each city's report says which. Tree cover is measured over the same 2 km radius in every city, so the cities compare like for like.
