Deforestation · 2001–2025
Which has lost more forest, Gaziantep or İzmir?
İzmir has lost more: about 471 ha of forest within 10 km of its center from 2001 to 2025, against 2 ha around Gaziantep. 88 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: 2019, with under 1 ha lost.
Worst year: 2025, with 93 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.

Which has more trees, Gaziantep or İzmir?
İzmir has more tree cover: 9.6% of the land within 2 km of its center against 4.1% around Gaziantep, or about 26,691 trees against 12,881. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Gaziantep and İzmir need?
Gaziantep needs about 81,367 more to reach its canopy target of 30%, and İzmir about 70,620 to reach 35%. The target starts at 30% of the land and rises where air quality is poor.
Are Gaziantep and İzmir 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 Gaziantep vs İzmir 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 16, 2026 and Sep 18, 2026), and the forest figures are published yearly.
