What the satellite crop condition data holds
Cropland vegetation per administrative unit across 4 countries: 47 Kenyan counties, 31 Tanzanian regions, 135 Ugandan districts and 30 Rwandan districts. 2 products sit under the source tag. A 10 m product supplies 4 indices per unit and week: NDVI for greenness, NDRE for chlorophyll, SAVI for greenness with the soil signal damped down, NDMI for canopy moisture. A 300 m product supplies NDVI from 2018 onward and, from July 2026, a soil water index alongside it. The 10 m values are averaged over cropland only, so a value reflects what the fields themselves are doing, not the towns, forests and lakes sitting around them.
Against its own normal
The demand signal compares each unit only with itself: this week’s cropland vegetation against what the same weeks looked like across the 8 years before. A county that simply runs greener than its neighbours only counts as above normal once it beats its own record. The 10 m series is the live reading, the 300 m series is the climatology it’s read against; the platform calibrates the 2 per unit and, wherever they disagree past a set tolerance, serves the lagged reading and says so directly in the response. Thresholds of ±0.02 and ±0.05 sort the anomaly from well below to well above normal, and demand_outlook reads rising, steady or softening off the anomaly and its trend together. This dataset carries only the raw values; the anomaly, the outlook and the ranking all come from the demand signal and demand board analyses built on top of it.
Nakuru in 2026
The chart tracks the county’s 10 m NDVI across the year: 0.47 in early January, a low of 0.35 in early March just before the long rains, 0.68 at the start of June with the canopy fully closed, and back down to 0.46 by September. The 300 m product underneath follows the same season about 40 days later.
Across counties at the snapshot
Nandi read 0.66, Kericho 0.62, Kakamega 0.58, Marsabit 0.09. Against each county’s own normal, though, the picture shifts: Nandi sits at +0.03, Kakamega is exactly on normal, Marsabit at −0.18. The raw value says how green a county is; the anomaly says whether that’s unusual for it. The demand board ranks all 243 units this way every week, blended with how intensively each one farms, so a breadbasket county sitting merely on normal still outranks a pastoral district enjoying a rare green spell.
