Dar es Salaam vs Singida

Tree cover and air quality for both, measured the same way: Sentinel-2 imagery at 10 m detail over a 2 km radius from each city centre, and the live US EPA air quality index. Same radius and same index, so the two numbers compare directly.

Dar es Salaam has more tree cover — 11.1% against 6.0%.

Singida has cleaner air right now — AQI 19 against 32.

Reading these numbers

What is actually being measured

Tree cover

The share of ground under canopy inside a 2 km radius of each city centre, read from Sentinel-2 satellite imagery at 10 m detail. It is a measurement of that circle, not of the whole municipality — which is exactly what makes the two comparable, since city boundaries are drawn to wildly different rules around the world. Dar es Salaam leads here at 11.1%.

Air quality index

The live US EPA index, computed from current pollutant concentrations — ground stations where a city has them nearby, and a model everywhere else. It moves hour to hour, so this is a snapshot rather than a verdict on either place: Dar es Salaam reads 32 (good) and Singida reads 19 (good) right now.

Frequently asked

Dar es Salaam and Singida, answered

Which has more trees, Dar es Salaam or Singida?

Dar es Salaam, with roughly 34,837 trees inside its 2 km radius against 17,587. Tree cover tells a slightly different story from raw count: Dar es Salaam has the denser canopy at 11.1%.

Which has better air quality, Dar es Salaam or Singida?

Singida right now, at AQI 19 against 32 — a gap of 13 points. This is a live reading rather than an annual average, so it can reverse within a day.

How many more trees does each city need?

Dar es Salaam needs about 59,317 more to reach its canopy target, and Singida about 70,347. The target is the same share of ground for both, so the figures are directly comparable.

Are these two measured the same way?

Yes — that is the point of the page. Identical radius, identical satellite source at 10 m detail, and the same US EPA index for air. Nothing here is adjusted for population, city limits or climate, so the numbers describe the same-sized circle of ground in each place.
