Liên quan đến thông tin về việc các nhà máy điện rác ở Hà Nội không có số liệu quan trắc, đại diện cơ quan chức năng đã lên tiếng.
Lãnh đạo Trung tâm Kỹ thuật Nông nghiệp và Môi trường Hà Nội khẳng định tất cả các nhà máy điện rác đều phải thực hiện quan trắc online 24/24. Dữ liệu này được truyền trực tiếp về cơ quan quản lý để giám sát chặt chẽ.

Comparison of the median-seasoned NDVI for central Calgary: 2024 vs 2025
Here is a side-by-side look at how the vegetation conditions in central Calgary changed between two years, using median-seasoned NDVI maps derived from Sentinel-2 imagery.
You can clearly see the interannual differences in greenness — especially in parks, riparian zones, and residential areas with large tree cover.
The spatial patterns remain stable, but 2025 shows noticeably higher NDVI in many neighbourhoods due to more favourable moisture conditions.
This is part of my ongoing project on analyzing the vegetation dynamics of Calgary communities: #GreennessOfCalgary

In the distant 2016, when I was a member of an environmental NGO in Kryvyi Rih (Ukraine), I started using satellite Earth Observation data to monitor the condition of large industrial tailings ponds.
At that time, environmental regulations required these storage facilities to be either flooded or at least kept moist to prevent dust storms.
Industrial operators often ignored these rules, leaving huge dry surfaces exposed — which created massive dust pollution affecting nearby communities.
Using Sentinel-2 and Landsat-8 imagery with false-color composites, I developed a simple but effective method to map dry, moist, and water-covered zones of tailings ponds.
Local residents and journalists were absolutely delighted! Industrial companies, on the other hand… reacted very differently 🤣
These maps are from 2016–2017 and show several tailings facilities around #KryvyiRih.

🌿 Greenness of Calgary Communities (Summer 2024)
📎 https://www.datastory.org.ua/greenness-of-calgary-communities-summer-2024/
Last year I published my first attempt to analyze the actual vegetation condition across Calgary and to build a data-driven ranking of its communities based on median summer NDVI. It was my very first experiment in assessing urban greenness at the neighbourhood scale — but the results turned out surprisingly insightful.
Some patterns were expected, while others revealed unexpectedly low vegetation density in places that looked green from the ground.
This exploration later grew into a much larger line of research on Calgary’s greenness, climate resilience, and spatial variability in vegetation health. You can find some results here with thematic hashtag #GreennessOfCalgary
If you're working on urban ecology, remote sensing, or land-cover analysis of Canadian cities — I’d be happy to exchange ideas.

Here is the city-wide map of ΔNDVI for Calgary — the difference between the median summer NDVI (mid-May to mid-September) in 2024 vs 2025.
As in the previous post, the signal is quite clear:
2025 shows a systematic increase in vegetation index across almost the entire city, but some areas showing a decrease.
This pattern is consistent with what I see in the frequency distributions of median NDVI:
2025 has a broader, greener distribution — likely reflecting better moisture conditions and a more favourable growing season.
Working with ΔNDVI on a pixel-by-pixel scale (10 × 10 m) offers a much more detailed picture of how vegetation responds spatially, compared with community-level averages or city-wide summaries.

Wildfires in Dnipropetrovsk region: a one-week satellite chronicle (2018)
(In Ukrainian: Дніпропетровщина у вогні: тижнева космічна хроніка)
A short look at how quickly landscapes can change when dry vegetation is intentionally burned.
The main goal of the article was to draw attention to this destructive and widespread local practice of setting dry biomass on fire.
Using Sentinel-2 imagery, I documented how almost 3,000 hectares of land were burned within just one week.
The full article contains many more satellite images and comparisons.
👉 Full article (in Ukrainian): https://www.datastory.org.ua/%d0%b4%d0%bd%d1%96%d0%bf%d1%80%d0%be%d0%bf%d0%b5%d1%82%d1%80%d0%be%d0%b2%d1%89%d0%b8%d0%bd%d0%b0-%d1%83-%d0%b2%d0%be%d0%b3%d0%bd%d1%96-%d1%82%d0%b8%d0%b6%d0%bd%d0%b5%d0%b2%d0%b0-%d0%ba%d0%be%d1%81/
Intentional burning of dry biomass remains a serious ecological problem in many regions: it destroys soil, steppe ecosystems, and increases erosion and air pollution.
Remote sensing helps make this damage visible — and documented.

🌳 Random Forests and Living Trees
English translation of my earlier article on applying satellite imagery and machine learning to map urban land cover.
What started as a local research project in Kryvyi Rih turned into something much larger — the results sparked a heated discussion among residents, officials, and industry representatives about the real condition of green buffers around large industrial sites.
The methodology developed during that work is still being used today — adapted for new environmental and urban projects.

🌿 NDVI change in Calgary’s Weaselhead Flats (2024 → 2025)
This map shows how vegetation in one of Calgary’s most diverse natural areas responded to the city’s unusually wet summer of 2025.
Greener shades mark zones where NDVI increased most strongly compared to 2024 — the same floodplain and forest patches that locals know for dense canopy recovery.
Even modest year-to-year shifts in temperature and rainfall leave clear spatial traces in NDVI — a reminder of how sensitive urban ecosystems are to climate variability, and how well open-data satellite products can capture it.

🛰️ Land-cover classification with Sentinel-1 & Sentinel-2 — validated and working
My machine-learning model for land-cover classification has shown very high accuracy (both overall and per-class).
It was trained on multi-temporal Sentinel-1/2 data over one of Ukraine’s largest mining and industrial areas.
The model now serves as a base for analysing environmental dynamics and supporting real-world sustainability decisions.

It sounds like a curiosity, but the sensitivity of Unio tumidus to pollution https://pmc.ncbi.nlm.nih.gov/articles/PMC10714398/ is used by more than 50 water treatment plants across Poland. The mollusks control the water supply for 10 million people. Similar systems operate in the US (for example, in Minneapolis) https://www.cbsnews.com/minnesota/news/mussels-helping-monitor-water-quality-in-minneapolis/ and other countries. #EnvironmentalMonitoring #WaterTreatment #Poland #USA #Minneapolis #Mollusks #Bioindicators
