ظِلّ — أولويات التشجير الحضري في بريدة

Shade is a research platform for urban tree planting in Buraydah. It measures how much green cover each district has and how hot its surface gets in summer, then combines both with population density into a single priority score — so planting goes first to the districts that need shade the most.

City Indicators

• 69 districts, using Saudi National Address boundaries
• 571,169 residents (GASTAT 2022 census)
• 6.7% average green cover, from Sentinel-2 at 10 m resolution
• 52.2 m² of vegetation per resident, including palm farms inside the city
• 54.2 °C mean summer surface temperature, from Landsat 8/9 (June to August)

The Data

• Sentinel-2 composites for September–October 2025, compared with a 2019 baseline
• Landsat 8/9 thermal composite from 34 summer 2025 scenes
• District population from an ensemble of three sources: WorldPop, Kontur and Meta HRSL
• All inputs are open — no accounts or API keys needed

The Score

• The green-cover gap is measured against a 9% target
• Exposure combines surface heat and population density
• Districts are ranked 1 to 69, and a Monte-Carlo analysis of 3,000 runs reports how certain each top-10 place is

What It Includes

• An interactive dashboard with a priority map and a searchable district ranking
• CSV export and a printable brief report
• A full study in Arabic and English, a presentation and an introductory film
• A reproduction guide and an independent audit that recompute every published number
