Deforestation · 2001–2025
Which has lost more forest, Chipata or Ndola?
Ndola has lost more: about 2,860 ha of forest within 10 km of its center from 2001 to 2025, against 254 ha around Chipata. 278 ha of that was cleared for good, for farms, mines or towns.
Measured within 10 km of each center, from the yearly satellite maps of forest loss: a wider circle than the one for tree cover, because forest is usually lost at a city's edges.
Worst year: 2001, with 27 ha lost.
Worst year: 2012, with 1,150 ha lost.

Reading these numbers
How this comparison is made
Air quality index
The US EPA index, computed from current pollutant concentrations: ground stations where a place has them nearby, and the CAMS atmospheric model everywhere else. It moves hour to hour, so it is a snapshot rather than a verdict on either place. The guideline marks are from the WHO's 2021 air quality guidelines.
Trees and forest
Tree cover is the share of ground under canopy within 2 km of each center, read from Sentinel-2 satellite imagery at 10 m detail. It measures that circle, not the whole municipality, which is what makes the two comparable. Forest loss comes from the University of Maryland's Global Forest Change maps.

Frequently asked
Chipata vs Ndola: your questions answered
Is Chipata cleaner than Ndola?
On air quality, yes, right now: Chipata reads AQI 29 against 58, a gap of 29 points on the US EPA index. This is a live reading rather than an annual average, so it can reverse within a day. Over the past 6 days, on modeled daily averages, Chipata averaged AQI 59 against 67, and it was the cleaner of the two on 4 of those days.
Is it safe to exercise outdoors in Chipata and Ndola today?
In Chipata, at AQI 29: Air quality is satisfactory for everyone. In Ndola, at AQI 58: Unusually sensitive people should consider limiting long outdoor exertion.
Which has lost more forest, Chipata or Ndola?
Ndola has lost more: about 2,860 ha of forest within 10 km of its center from 2001 to 2025, against 254 ha around Chipata. 278 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Chipata or Ndola?
Ndola has more tree cover: 22.8% of the land within 2 km of its center against 19.9% around Chipata, or about 71,628 trees against 62,518. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Chipata and Ndola need?
Chipata needs about 31,730 more to reach its canopy target of 30%, and Ndola about 22,619 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Chipata and Ndola measured the same way?
The method is the same: the US EPA index for air, and Sentinel-2 satellite imagery at 10 m detail over an identical radius for trees. Both readings are model estimates, with no ground station close enough to either. Nothing is adjusted for population, city limits or climate.
How often does the Chipata vs Ndola comparison update?
The air readings refresh about once an hour, and each reading's local time is shown at the top of the page. Tree cover comes from the latest clear satellite image of each area (Sep 12, 2026 and Sep 17, 2026), and the forest figures are published yearly.
