Agroecology Map1d ago

🌱🛰️ Agroecology Map now has two new satellite layers for mapped locations: EVI and NDMI. These indicators help communities look at living landscapes from new angles, together with NDVI. They make it easier to follow vegetation, water stress, restoration, and seasonal change over time. 🗺️💚💧

Scientists See More Vegetation In The Himalayas - But It Is Not Good News, Because That Extra “Green” Can Disrupt Water, Snow, And High-Mountain Biodiversity | Plants Growing Higher Across Himalaya As Climate Warms

“For years, the biggest climate warning from the Himalaya was easy to picture because glaciers were shrinking on the roof of Asia. Now, researchers are pointing to a quieter signal, one that can look almost harmless from a distance. The mountains are getting greener.
New research [link above] shows alpine vegetation moving higher across six Himalayan regions from 1999 to 2022, pushed in part by warming and reduced snow depth. That might sound like nature recovering, but in this fragile landscape, more plant cover at extreme heights may change how snow is stored, how water runs downhill, and how rivers behave for communities far below…”

5. The Paradox of Greening

Satellite tracking measures a massive increase in the Normalized Difference Vegetation Index (NDVI), meaning the Arctic is getting visibly greener. However, this greening is not an environmental victory. The incoming dark tree canopies and tall shrubs destroy the snow's high albedo effect; instead of reflecting sunlight back into space, they act as a dark thermal sponge.

🏡 Here is the data analysis for Calgary, Summer 2025. This chart shows the relationship between vegetation density (NDVI) and Land Surface Temperature (LST).

🔥 The data reveals a critical "tipping point": vegetation only starts effectively cooling the environment once it reaches a specific density threshold. Below this threshold (the left side of the curve), green spaces stay just as hot as the surrounding concrete.
Sparse or isolated trees don't act as air conditioners—they "burn" in the urban furnace right along with us.

❗ What does this mean for Calgary? Simply planting a few scattered trees isn't enough. To actually move the needle on temperature, we need dense, healthy green belts. Otherwise, it’s just a waste of water and resources.

How hot was Calgary's neighborhood in 2025? 🛰️🌡️

I processed satellite data from last summer to see how Calgary’s communities handle the heat. It turns out that not all greenery is equal. My research shows a clear "breakpoint" where the density of vegetation actually starts to drop the surface temperature.

I’ve mapped the "Hottest" and "Coolest" communities — see where yours stands and why some "green" areas are still overheating.

Calgary experienced a very wet and rainy summer in 2025. Naturally, the city’s vegetation responded vigorously to the high moisture levels, showing lush growth compared to the scorching summer of 2024. 🌿
Among residential areas, tiny Roxboro showed the most significant "greening"! Meanwhile, the lowest "recovery" rates were observed in the city's newest communities.
