Deforestation · 2001–2025
Which has lost more forest, Maputo or Nampula?
Nampula has lost more: about 113 ha of forest within 10 km of its center from 2001 to 2025, against 25 ha around Maputo. 113 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: 2009, with 4 ha lost.
Worst year: 2010, with 20 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.
More on the method on the About Airleaf page.
Frequently asked
Maputo vs Nampula: your questions answered
Is Nampula cleaner than Maputo?
On air quality, yes, right now: Nampula reads AQI 26 against 48, a gap of 22 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 7 days, on modeled daily averages, Nampula averaged AQI 38 against 40, and it was the cleaner of the two on 4 of those days.
Is it safe to exercise outdoors in Maputo and Nampula today?
The advice is the same for both today. Air quality is satisfactory for everyone. Maputo reads AQI 48 and Nampula reads AQI 26.
Which has lost more forest, Maputo or Nampula?
Nampula has lost more: about 113 ha of forest within 10 km of its center from 2001 to 2025, against 25 ha around Maputo. 113 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Maputo or Nampula?
Maputo has more tree cover: 15.0% of the land within 2 km of its center against 7.3% around Nampula, or about 43,637 trees against 22,934. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Maputo and Nampula need?
Maputo needs about 43,637 more to reach its canopy target of 30%, and Nampula about 71,314 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Maputo and Nampula 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 Maputo vs Nampula 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 16, 2026 and Sep 18, 2026), and the forest figures are published yearly.
