Deforestation · 2001–2025
Which has lost more forest, Caracas or Ciudad Guayana?
Ciudad Guayana has lost more: about 1,320 ha of forest within 10 km of its center from 2001 to 2025, against 297 ha around Caracas. 1,290 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: 2015, with 33 ha lost.
Worst year: 2008, with 128 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
Caracas vs Ciudad Guayana: your questions answered
Is Ciudad Guayana cleaner than Caracas?
On air quality, yes, right now: Ciudad Guayana reads AQI 14 against 33, a gap of 19 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, Ciudad Guayana averaged AQI 43 against 65, and it was the cleaner of the two on 5 of those days.
Is it safe to exercise outdoors in Caracas and Ciudad Guayana today?
The advice is the same for both today. Air quality is satisfactory for everyone. Caracas reads AQI 33 and Ciudad Guayana reads AQI 14.

Ciudad Guayana has lost more: about 1,320 ha of forest within 10 km of its center from 2001 to 2025, against 297 ha around Caracas. 1,290 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Caracas or Ciudad Guayana?
Caracas has more tree cover: 29.5% of the land within 2 km of its center against 16.1% around Ciudad Guayana, or about 92,677 trees against 50,580. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Caracas and Ciudad Guayana need?
Caracas needs about 1,571 more to reach its canopy target of 30%, and Ciudad Guayana about 43,668 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Caracas and Ciudad Guayana 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 Caracas vs Ciudad Guayana 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 8, 2026 and Sep 14, 2026), and the forest figures are published yearly.
