Comparing satellite maps from 2000 and 2020, the forest around Kanayannur stayed about the same size, at about 8,140 hectares: new forest grew on about 87 hectares, and about 124 hectares were lost.
These 2000 and 2020 maps, from the University of Maryland, count any land with trees taller than 5 m as forest, including plantations and orchards. Forest that was cut or burned and had grown back by 2020 counts in both years, so the loss here is smaller than the yearly figures.
These figures cover everything within 10 km of the city center, a wider area than the report above, because forest is usually lost at a city's edges.

Frequently asked
Questions about Kanayannur
What is the air quality (AQI) in Kanayannur right now?
The latest reading for Kanayannur shows an AQI of 97 (Moderate), observed Nov 11, 06:30 local time via Open-Meteo / CAMS, corrected with 2 ground-station cities within 125 km, US EPA index. The main pollutant is PM2.5. Unusually sensitive people should consider limiting long outdoor exertion.
Is it safe to exercise outside in Kanayannur today?
At AQI 97 (Moderate): fine for most people; unusually sensitive people should take long or hard exercise easier. Windows: fine to open; close them if you are sensitive to pollution. Masks: not needed for most people. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Kanayannur been like this week?
Over the last 7 days, the CAMS air-quality model put Kanayannur's daily AQI at 79 on average, from 70 on Nov 7 to an hourly peak of 114 on Nov 6. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Kanayannur's AQI the same as India's AQI (CPCB)?
No. Airleaf shows the US EPA Air Quality Index (AQI), the scale used by IQAir and most air-quality apps. India's Central Pollution Control Board (CPCB) publishes the National Air Quality Index on its own scale: 0–50 good, 51–100 satisfactory, 101–200 moderate, 201–300 poor, 301–400 very poor and 401–500 severe. The two scales don't line up. At moderate fine-particle levels the US scale reads higher: 55 µg/m³ of PM2.5 is 149 on the US AQI but about 92, "satisfactory", on India's. In heavy smog India's reads higher: 100 µg/m³ is 182 on the US AQI and about 232, "poor", on India's. CPCB also averages particles over 24 hours, so its figure moves more slowly than an hourly reading.
How much forest has the area around Kanayannur lost since 2001?
Since 2001, the area within 10 km of Kanayannur has lost about 56 hectares of forest (about 79 football pitches): 3.8% of the forest it had in 2000. Most of it (87%) was deforestation, forest cleared for good, mainly for towns and roads. Comparing satellite maps from 2000 and 2020, the forest around Kanayannur stayed about the same size, at about 8,140 hectares: new forest grew on about 87 hectares, and about 124 hectares were lost.
What is the tree count in Kanayannur?
Kanayannur has an estimated 45,962 trees across the 6.69 km² of land measured — 27.5% tree cover, 2 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Kanayannur need?
Kanayannur needs roughly 4,178 more trees to close a 2-point shortfall against its 30% tree-cover target — about 91.9 t of extra CO₂ absorbed per year once grown.
How are Kanayannur's air quality and tree cover measured?
Air quality comes from ground monitoring stations via OpenAQ where one reports nearby, and otherwise, as here, from the Open-Meteo / CAMS model, which may differ from street-level monitors. Tree cover is measured from Sentinel-2 L2A (ESA Copernicus) via Earth Search satellite imagery at 10 m detail across a 2 km radius around Willingdon Island; the tree count is an estimate derived from that cover.
