Deforestation · 2001–2025
Which has lost more forest, Cobán or Guatemala City?
Cobán has lost more: about 8,280 ha of forest within 10 km of its center from 2001 to 2025, against 1,270 ha around Guatemala City. 6,210 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: 2016, with 1,110 ha lost.
Worst year: 2012, with 137 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
Cobán vs Guatemala City: your questions answered
Is Cobán cleaner than Guatemala City?

Which has more trees, Cobán or Guatemala City?
Cobán has more tree cover: 52.8% of the land within 2 km of its center against 17.9% around Guatemala City, or about 165,876 trees against 56,235. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Cobán and Guatemala City need?
Cobán needs about 0 more to reach its canopy target of 30%, and Guatemala City about 38,013 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Cobán and Guatemala City 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. Guatemala City is read from a nearby ground station and Cobán is a model estimate, so the two are not quite like for like. Nothing is adjusted for population, city limits or climate.
How often does the Cobán vs Guatemala City 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 10, 2026 and Aug 16, 2026), and the forest figures are published yearly.
