Deforestation · 2001–2025
Which has lost more forest, Córdoba or Mar del Plata?
Córdoba has lost more: about 64 ha of forest within 10 km of its center from 2001 to 2025, against 62 ha around Mar del Plata. 60 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 11 ha lost.
Worst year: 2025, with 14 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
Córdoba vs Mar del Plata: your questions answered
Is Mar del Plata cleaner than Córdoba?
On air quality, yes, right now: Mar del Plata reads AQI 17 against 29, a gap of 12 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, Mar del Plata averaged AQI 31 against 35, and it was the cleaner of the two on 5 of those days.
Is it safe to exercise outdoors in Córdoba and Mar del Plata today?
The advice is the same for both today. Air quality is satisfactory for everyone. Córdoba reads AQI 29 and Mar del Plata reads AQI 17.
Which has lost more forest, Córdoba or Mar del Plata?
Córdoba has lost more: about 64 ha of forest within 10 km of its center from 2001 to 2025, against 62 ha around Mar del Plata. 60 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Córdoba or Mar del Plata?
Mar del Plata has more tree cover: 11.5% of the land within 2 km of its center against 8.3% around Córdoba, or about 32,407 trees against 26,049. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Córdoba and Mar del Plata need?
Córdoba needs about 68,104 more to reach its canopy target of 30%, and Mar del Plata about 52,133 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Córdoba and Mar del Plata 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 Córdoba vs Mar del Plata 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 (Mar 2, 2026 and Mar 15, 2026), and the forest figures are published yearly.
