Deforestation · 2001–2025
Which has lost more forest, Managua or Matagalpa?
Matagalpa has lost more: about 838 ha of forest within 10 km of its center from 2001 to 2025, against 263 ha around Managua. 791 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: 2006, with 31 ha lost.
Worst year: 2023, with 134 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
Managua vs Matagalpa: your questions answered
Is Matagalpa cleaner than Managua?
On air quality, yes, right now: Matagalpa reads AQI 8 against 43, a gap of 35 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, Matagalpa averaged AQI 25 against 27, and it was the cleaner of the two on 4 of those days.
Is it safe to exercise outdoors in Managua and Matagalpa today?
The advice is the same for both today. Air quality is satisfactory for everyone. Managua reads AQI 43 and Matagalpa reads AQI 8.
Which has lost more forest, Managua or Matagalpa?
Matagalpa has lost more: about 838 ha of forest within 10 km of its center from 2001 to 2025, against 263 ha around Managua. 791 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Managua or Matagalpa?
Matagalpa has more tree cover: 41.7% of the land within 2 km of its center against 17.7% around Managua, or about 131,004 trees against 55,606. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Managua and Matagalpa need?
Managua needs about 38,642 more to reach its canopy target of 30%, and Matagalpa about 0 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Managua and Matagalpa 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 come from nearby ground stations. Nothing is adjusted for population, city limits or climate.
How often does the Managua vs Matagalpa 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 (Aug 15, 2026 and May 12, 2026), and the forest figures are published yearly.
