📰 Curb‑cutting Resistance Helped Reshape Tucson’s Urban Ecology

🌧️ Tucson: A man illegally diverted rainwater into streetside basins in 1998. Years later, it transformed a desert neighborhood into a shaded, food‑producing micro‑ecosystem.

🌵 The approach revived Indigenous rain‑harvesting traditions but also caused Tucson to change water management laws to be more nature positive.

How much does landform position matter for vegetation dynamics across Calgary?

I explored how ΔNDVI (2025-2024) varies across geomorphon classes (summit, ridge, slope, hollow, valley, etc.) using a large spatial dataset (~194k observations).

A few key points from the analysis:
• Non-parametric Kruskal–Wallis test shows statistically significant differences between geomorphons
• However, the effect size is moderate (ε² ≈ 0.04)
• Distributions strongly overlap — landform position matters, but it is not a deterministic driver
• Median ΔNDVI tends to be higher in lower landscape positions (hollows, footslopes, valleys), consistent with moisture and accumulation controls
