Deforestation · 2001–2025
Which has lost more forest, Budta or Davao?
Davao has lost more: about 1,330 ha of forest within 10 km of its center from 2001 to 2025, against 539 ha around Budta. 1,320 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: 2010, with 75 ha lost.
Worst year: 2010, with 205 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
Budta vs Davao: your questions answered
Is Budta cleaner than Davao?
On air quality, yes, right now: Budta reads AQI 4 against 6, a gap of 2 points on the US EPA index. This is a live reading rather than an annual average, so it can reverse within a day. But over the past 7 days, on modeled daily averages, Davao averaged AQI 31 against 34, and it was the cleaner of the two on 4 of those days.
Is it safe to exercise outdoors in Budta and Davao today?
The advice is the same for both today. Air quality is satisfactory for everyone. Budta reads AQI 4 and Davao reads AQI 6.
Which has lost more forest, Budta or Davao?
Davao has lost more: about 1,330 ha of forest within 10 km of its center from 2001 to 2025, against 539 ha around Budta. 1,320 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Budta or Davao?
Budta has more tree cover: 70.8% of the land within 2 km of its center against 10.0% around Davao, or about 222,202 trees against 25,667. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Budta and Davao need?
Budta needs about 0 more to reach its canopy target of 30%, and Davao about 51,334 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Budta and Davao 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. Davao is read from a nearby ground station and Budta 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 Budta vs Davao 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 19, 2026 and Sep 19, 2026), and the forest figures are published yearly.
