Deforestation · 2001–2025
Which has lost more forest, Alexandria or Port Said?
Alexandria has lost more: about 19 ha of forest within 10 km of its center from 2001 to 2025, against 16 ha around Port Said. 11 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: 2008, with 3 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
Alexandria vs Port Said: your questions answered
Is Port Said cleaner than Alexandria?
On air quality, yes, right now: Port Said reads AQI 53 against 94, a gap of 41 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, Port Said averaged AQI 33 against 39, and it was the cleaner of the two on 4 of those days.
Is it safe to exercise outdoors in Alexandria and Port Said today?
The advice is the same for both today. Unusually sensitive people should consider limiting long outdoor exertion. Alexandria reads AQI 94 and Port Said reads AQI 53.
Which has lost more forest, Alexandria or Port Said?
Alexandria has lost more: about 19 ha of forest within 10 km of its center from 2001 to 2025, against 16 ha around Port Said. 11 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Alexandria or Port Said?
Alexandria has more tree cover: 3.9% of the land within 2 km of its center against 1.1% around Port Said, or about 9,655 trees against 2,177. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Alexandria and Port Said need?
Alexandria needs about 64,613 more to reach its canopy target of 30%, and Port Said about 57,199 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Alexandria and Port Said 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 Alexandria vs Port Said 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 17, 2026 and Sep 16, 2026), and the forest figures are published yearly.
